NHTSA Interpretation File Search
Overview
NHTSA's Chief Counsel interprets the statutes that the agency administers and the standards and regulations that it issues. Members of the public may submit requests for interpretation, and the Chief Counsel will respond with a letter of interpretation. These interpretation letters look at the particular facts presented in the question and explain the agency’s opinion on how the law applies given those facts. These letters of interpretation are guidance documents. They do not have the force and effect of law and are not meant to bind the public in any way. They are intended only to provide information to the public regarding existing requirements under the law or agency policies.
Understanding NHTSA’s Online Interpretation Files
NHTSA makes its letters of interpretation available to the public on this webpage.
An interpretation letter represents the opinion of the Chief Counsel based on the facts of individual cases at the time the letter was written. While these letters may be helpful in determining how the agency might answer a question that another person has if that question is similar to a previously considered question, do not assume that a prior interpretation will necessarily apply to your situation.
- Your facts may be sufficiently different from those presented in prior interpretations, such that the agency's answer to you might be different from the answer in the prior interpretation letter;
- Your situation may be completely new to the agency and not addressed in an existing interpretation letter;
- The agency's safety standards or regulations may have changed since the prior interpretation letter was written so that the agency's prior interpretation no longer applies; or
- Some combination of the above, or other, factors.

ID: RECARO_e-registration7970OpenMr. Dan Mullins Dear Mr. Mullins: This replies to your inquiry as to whether the recent amendments to Federal Motor Vehicle Safety Standard (FMVSS) No. 213 require your company to revise its on-line registration form. As explained below, so long as online registration information is not provided on the paper registration form, your electronic registration form is not subject to the format requirements of the standard. To improve the effectiveness of manufacturer campaigns recalling child restraint systems (CRSs) that contain a safety defect or fail to conform to FMVSS No. 213, manufacturers are required to provide a registration form (hereafter referred to as a "paper form") with each restraint (S5.8). The paper form must conform in size, content and format to the form depicted in the standard (figures 9a and 9b). To minimize the potential for confusion, no other information is permitted to appear on the paper form except for information that distinguishes a particular restraint from other systems. In your e-mail you indicate that RECARO provides an electronic registration form on its website and that the internet address for the electronic form is provided in the CRS instruction manuals. You further state that the internet address is not provided on the paper form. You then ask if recent amendments to FMVSS No. 213 would subject RECAROs electronic registration form to the standards format requirements under this scenario. On September 9, 2005, we amended FMVSS No. 213, in part, to permit the inclusion of an internet address for electronic registration of a CRS on the paper form (70 FR 53569). If a manufacturer chooses to provide such information, the website address must also be provided in the instruction manual (S5.6.1.7 and S5.6.2.2) and the format of the electronic registration form must conform to S5.8.2 (S5.8.1(d)). However, S5.8.2 is only applicable if a manufacturer voluntarily provides an internet address for electronic registration on the paper form. We noted in the final rule that the amendments did not establish any new requirements for CRS manufacturers. If a manufacturer does not include an internet address on the paper form, then the electronic registration requirements do not apply even if the manufacturer elsewhere provides information on electronic registration. I hope you find this information helpful. If you have any additional questions, please contact Mr. Chris Calamita of my staff at (202) 366-0536. Sincerely, Stephen P. Wood ref:213 |

ID: 1983-1.10OpenTYPE: INTERPRETATION-NHTSA DATE: 01/28/83 FROM: AUTHOR UNAVAILABLE; Frank Berndt; NHTSA TO: Mazda (North America) Inc. TITLE: FMVSS INTERPRETATION TEXT: This responds to your November 15, 1982 letter regarding the applicability of certain requirements in Federal Motor Vehicle Safety Standard (FMVSS) 219, Windshield Zone Intrusion, to two proposed cowl designs. FMVSS 219 provides that no part of a vehicle outside the occupant compartment, "except windshield molding and other components designed to be normally in contact with the windshield," may penetrate a specified protected zone template on the windshield during a vehicle test crash. In your letter, you present two possible vehicle designs in which the cowl would directly contact the windshield. In one design, the contact would occur across most of the width of the windshield, while in the other, the contact occurs only at the outside edges of the cowl. Both designs appear to fall within the exception in the standard for components "designed to be normally in contact with the windshield," and therefore the cowl would be permitted to penetrate the protected zone template. Nevertheless, I should mention that your second design does raise some concerns. It is difficult to determine from the drawings enclosed with your letter the extent of the windshield-cowl contact in your second design. If this contact were for such a short distance that it would be apparent that the design was intended to circumvent FMVSS 219 by establishing only minimal contact, the agency would consider taking appropriate action to assure that the intent of the standard is carried out. SINCERELY, MAZDA (NORTH AMERICA), INC. Detroit Office November 15, 1982 Frank Berndt Chief Counsel National Highway Traffic Safety Administration RE: Interpretation of FMVSS 219, Windshield Zone Intrusion Dear Mr. Berndt: Mazda respectfully submits this letter to request an interpretation of the requirements (S5.) of FMVSS 219, Winshield Zone Intrusion. The requirement states, ". . . . .No part of the vehicle outside the occupant compartment, except windshield molding and other components designed to be normally in contact with the windshield, . . . . . . . . . . ." Mazda is developing a new model in which the cowl, by design, contacts the lower portion of the windshield. There are two designs being considered, as shown in the attached sketches. According to our interpretation of the standard, the cowl would be part of "other components designed to be normally in contact with the windshield". We would appreciate your interpretation with regard to this matter at your earliest convenience. Thank you. H.

Mr H. Nakaya Manager Mazda (North America) Inc. 23777 Greenfield Road - Suite 462 Southfield, MI 48075
Dear Mr. Nakaya:
This is in response to your letter of July 8 1983 asking for an interpretation of Motor Vehicle Safety Standard No. 108. Section S4.2 of SAE Standard J588e Turn Signal Lamps establishes a minimum distance of 4 inches from the optical axis (filament center) of the front turn signal to the inside diameter of the retaining ring of the headlamp providing the lower beam. You believe that it is not necessary to have a retaining ring on a semi-sealed headlamp and you have asked whether you may substitute the edge of the reflector (as shown on your drawing) to measure the dimension covered by S4.2 of J588e.
The point depicted on your drawing appears to be the inner edge of the reflector, rather than the extreme edge; nevertheless, the "reflector edge" you have indicated is the approximate location of a retaining ring on a fully sealed headlamp, and is therefore acceptable as a measuring point under Standard No. 108. Sincerely,
Frank Berndt Chief Counsel
July 8, 1983
Mr. Frank Berndt Chief Counsel National Highway Traffic Safety Administration 400 Seventh Street, S.W. Washington; D.C. 20590
Dear Mr. Berndt:
Mazda requests interpretation regarding the amendment to FMVSS No.108 which allows the use of semi-sealed headlamps (Docket No. 81-11; Notice 3, 48 F.R. 24690).
Section 4.2 of SAE Standard J588e states that, "The optical axis (filament center) of the front turn signal shall be at least 4 in. from the inside diameter of the retaining ring of the headlamp unit providing the lower beam." However, it is not necessary to have a retaining ring on a semi-sealed headlamp. We, therefore, believe that it is appropriate to use the edge of the reflector, instead of the inside diameter of the retaining ring, to measure the dimension described in Section 4.2 of SAE Standard J588e (See attached sketch).
We would appreciate your interpretation of this matter as soon as possible.
Very truly yours, H. Nakaya Manager

WAIMEY, DEAN HANSELL, LAW OFFICES OF DONOVAN, LEISURE, NEWTON & IRVINE TITLE: NONE ATTACHMT: ATTACHED TO LETTER DATED 12/09/88 FROM ERIKA Z. JONES -- NHTSA TO LANCE E. TUNICK, REDBOOK A33, STANDARD 208; LETTER DATED 11/10/75 FROM FRANK A. BERNDT TO JOHN B. WHITE, N40-30, SECTION 108(B)(5); LETTER DATED 10/20/88 FROM LANCE E. TUNICK TO ERIKA Z. JONES, REQUEST FOR INTERPRETATION OF FMVSS 208, OCC 2696 TEXT: Dear Mr. Waimey and Mr. Hansell: Thank you for your letter of April 15, 1985, concerning the automatic restraint requirements of Federal Motor Vehicle Safety Standard No. 208, Occupant Crash Protection. I regret the delay in our reply. You asked about the requirement in S4.1.3 of the standard concerning the minimum annual production of passenger cars that must be equipped with automatic restraints. You stated your assumption that the standard applies only to vehicles produced for sale in the United States and asked how a manufacturer is to determine if a vehicle is a part of its annual production for the United States. You pointed out that there are a number of possible sales transactions, beginning with the sale of a vehicle by Porsche to the U.S. importer and ending with the first sale to a consumer in the U.S. that can be used in determining at which point a vehicle becomes part of Porsche's annual production for the United States. I hope the following discussion answers your question. As discussed in the agency's April 12, 1985, (50 FR 14596) notice on Standard No. 208, your assumption that the term "average annual production" refers only to cars manufactured for sale in the United States is correct. S4.1.3 specifies that percentages of production are to be based on the number of cars manufactured between discrete dates. In the case of foreign cars, as in the case of domestic ones, "manufactured" means produced or assembled. Part 567 Certification (49 CFR Part 567) of the agency's regulation requires all vehicles manufactured for sale in the United States to have a tag affixed to them certifying that they meet all Federal Motor Vehicle Safety Standards. Therefore, in determining which vehicles are to be counted as the manufacturer's average annual production, the manufacturer should determine how many vehicles were produced and certified in accordance with our regulation during the applicable time period. Using production and certification provides the agency and manufacturers with an easily verifiable event to determine which cars are to be counted. I hope this information is of assistance to you. If you have further questions, please let me know.
Sincerely, |

Washington D.C. 20044-0407; "Dear Ms. Semo: This responds to your request for NHTSA's determinatio that certain former East German military trucks, ZIL model 131, are not motor vehicles, and exempt from the Federal Motor Vehicle Safety Standards (FMVSS). We are unable to make such a determination. As explained below, a ZIL model 131 truck imported into the United States is considered a 'motor vehicle' for purposes of the National Traffic and Motor Vehicle Safety Act (Safety Act)(15 U.S.C. 1391 et seq.), and is subject to the FMVSS. Your letter explained that a client plans to import over 500 ZIL model 131 trucks into the U.S. Apparently, your client plans to modify the trucks in the U.S. to use for nonmilitary purposes. Your client intends to send most of the modified trucks to buyers in other countries, but plans to sell some of the trucks in the U.S. Your letter states: '... S ome ZIL vehicles may be modified to meet DOT/NHTSA and EPA standards in order to satisfy those buyers who require vehicles conforming to those standards.' Under the Safety Act, any 'motor vehicle,' whether new or used, that is imported into the United States for sale in this country must be brought into conformity with all FMVSS that applied at the time of its manufacture. The question that must be answered is whether the ZIL 131 trucks, at the time of importation, would be considered 'motor vehicles.' 'Motor vehicle' is defined at section 102(3) of the Safety Act (15 U.S.C. 1391(3)) as: A ny vehicle driven or drawn by mechanical power manufactured primarily for use on the public streets, roads, and highways, except any vehicle operated exclusively on a rail or rails. NHTSA has interpreted this language as follows. Vehicles that are equipped with tracks or are otherwise incapable of highway travel are not motor vehicles. Further, vehicles designed and sold only for off-road use (such as airport runway vehicles and underground mining devices) are not considered motor vehicles, even though they may be operationally capable of highway travel. Vehicles that have an abnormal body configuration that readily distinguishes them from other highway vehicles and a maximum speed of 20 miles per hour (mph) are not considered motor vehicles, because their use of the public roads is intermittent and incidental to their primary intended off-road use. On the other hand, vehicles that use the public highways on a necessary and recurring basis are motor vehicles. For instance, a utility vehicle like the Jeep is plainly a motor vehicle, even though it is equipped with special features to permit off-road operation. If a vehicle's greatest use will be off-road, but it will spend a substantial amount of time on-road, NHTSA has interpreted the vehicle to be a 'motor vehicle.' Further, the agency has determined that a vehicle such as a dune buggy is a motor vehicle if it is readily usable on the public roads and is in fact used on the public roads by a substantial number of owners, regardless of the manufacturer's stated intent regarding the terrain on which the vehicle is to be operated. Applying the above criteria, and based on the information in your letter, the ZIL model 131 trucks are motor vehicles. You state that potential U.S. buyers would require vehicles that meet the FMVSS. This suggests that U.S. vehicle owners intend to use the ZIL model 131 trucks as they would other motor vehicles, on the public roads. Judging from your photographs, the trucks do not have abnormal body configurations that distinguish them from other vehicles on the road. You stated that the trucks have a top speed of almost 50 miles per hour, a speed suitable for public roads. These facts suggest that the ZIL model 131 truck is designed and intended to be routinely used on the public roads, and should be classified as a motor vehicle. Assuming your client is still interested in importing the ZIL 131 trucks for resale in the U.S., the Imported Vehicle Safety Compliance Act requires that the agency determine that the vehicles are capable of conversion to meet the FMVSS, and that the trucks be imported by a 'registered importer.' The agency makes determinations upon the basis of a petition by the manufacturer or registered importer (or upon its own volition). A 'registered importer' is one whom NHTSA has recognized as capable of converting vehicles to meet the FMVSS. If you would like further details on eligibility determinations and import procedures, please let us know and we shall be pleased to provide them. The Safety Act also addresses trucks your client wishes to import into the U.S. for modification for export. Under section 108(b)(3) of the Safety Act, the FMVSSs do not apply to vehicles intended solely for export. Thus, trucks brought into the U.S. for modification for export are not subject to the FMVSSs. Under 49 CFR 591.5, the importer would file a declaration under 591.5(c), that the vehicle does not comply with all applicable Federal motor vehicle safety, bumper, and theft prevention standards, but is intended solely for export. I hope that this information is helpful. If you have any questions, please contact Dorothy Nakama of my staff at this address or at (202) 366-2992. Sincerely, John Womack Acting Chief Counsel"; |

ID: aiam3107OpenMr. Hisakazu Murakami, Nissan Motor Co., Ltd., Suite No. 1012, 1028 Connecticut Avenue, N.W., Washington, DC 20036; Mr. Hisakazu Murakami Nissan Motor Co. Ltd. Suite No. 1012 1028 Connecticut Avenue N.W. Washington DC 20036; Dear Mr. Murakami: This responds to your recent letter requesting an interpretatio concerning the proper 'designated seating capacity' for three hypothetical seat designs. You ask whether each of the designs would be permitted to have only two 'designated seating positions.'; The amended definition of 'designated seating position' provides, i part, that any bench or split-bench seat having greater than 50 inches of hip room shall have not less than three designated seating positions, unless the seat design or vehicle design is such that the center position cannot be used for seating.; Your three hypothetical designs are derived from a basic seat desig having 52 inches of hip room (Figure 1 in your letter). This basic design would be required to have three designated seating positions since it has greater than 50 inches of hip room, unless the center position cannot be used because of some obstruction or other impediment. You ask whether the agency would consider the three hypothetical designs illustrated in your letter to adequately establish impediments to use of the center position.; Your 'Figure 2' illustrates an unpadded depression at the cente position of the bench seat. Since this center depression is unpadded, 3.1 inches deep and 6.7 inches wide, it is the agency's opinion that the center position lacks an essential attribute of a seating position and would not likely be used for seating (even though there might be some unorthodox use of the position from time to time). If a seat of this design is equipped with seat belt assemblies, location of assembly hardware in the center depression would further clarify that the area is not a seating position. It must be emphasized, however, that designs of this type would be required to have three designated seating positions if the depth and width of the depression is so minimal that a person could easily straddle the depression and use the center position. Also, stiffness of seat belt assembly hardware located in the center depression becomes a more determinative factor the more narrow the width of such a depression.; The seat design illustrated in 'Figure 3' of your letter includes 'partition pipe' at the center of the seat cushion. Whether such a design would preclude the use of the center position would depend greatly on the physical dimensions and characteristics of the 'pipe' that is used and whether it is removable. If the 'pipe' were made of soft, pliable padding similar to the other portions of the seat, for example, the 'pipe' might not be sufficient to discourage use of the center position. Since your letter provides no information on the nature of the 'partition pipe' that is illustrated, the agency cannot offer an opinion concerning this design.; In 'Figure 4,' there is a padded 'swelling' in the center sea position. Although the Figure specifies a height of 3.9 inches at the front of the 'swelling,' it appears that the 'swelling' slants down toward the seat back so that it is only about one-half inch high where it joins the seat back. The illustration also does not describe whether the 'swelling' is made of soft padding or of some rigid material. Without this information, the agency cannot offer an opinion concerning this design. I would point out, however, that if the 'swelling' is made of soft, flexible padding, it would not likely discourage use of the center position. In fact, if as it appears the 'swelling' slants down to the seat back to create a 'saddle effect,' young children might be encouraged to use this center position.; To summarize, it is the agency's opinion that 'Figure 2' in your lette illustrates a seat design that could qualify as having two designated seating positions. Regarding Figures 3 and 4, your letter did not include sufficient information for the agency to provide an opinion. On the basis of the information that was provided, however, I would say that these two designs are very dubious and do not indicate an adequate attempt on the part of the manufacturer to clarify that the center position is not to be used. It does not behoove a manufacturer to attempt to come narrowly within the meaning of the amended definition of 'designated seating position.' It would be much wiser to make sure that there is no question that the center position is not to be used. In the design illustrated in your 'Figure 4,' for example, you could easily design the 'swelling' to be 4 or more inches tall from front to rear and made of a rigid material, and there would be no question concerning your compliance.; Finally, I would emphasize that this letter only represents th agency's opinion based on the information supplied in your letter. The NHTSA does not pass approval on any vehicle design, for any safety standards, prior to the actual events that underlie certification. It is up to the manufacturer to determine whether its vehicles comply with all applicable safety standards and regulations, and to certify its vehicles in accordance with that determination.; Sincerely, Frank Berndt, Chief Counsel |

ID: aiam5651OpenDorothy Jean Arnold, M.D. 15 Fairview Knoll N.E. Iowa City, Iowa 52240-9147; Dorothy Jean Arnold M.D. 15 Fairview Knoll N.E. Iowa City Iowa 52240-9147; "Dear Dr. Arnold: This responds to your letter asking whether the ai bags in your car can be disconnected. You explained that you are physically impaired by the effects of osteomyelitis, a disease of the bones, cannot use a seatbelt with comfort, and were granted dispensation from such usage several years ago. In a telephone conversation with Richard Reed of this agency, you indicated that you are 74 years old, 5 feet, three inches tall, and must sit close to the steering wheel because of your medical condition. As explained below, our answer is that NHTSA will not institute enforcement proceedings against a repair business that disconnects an air bag on your vehicle to accommodate your condition. Standard No. 208, Occupant Crash Protection, requires that cars be equipped with automatic crash protection at the front outboard seating positions. The air bags in your car were installed as one means of complying with that requirement. The removal or deactivation of one of those air bags by a vehicle dealer is governed by a provision of Federal law, 49 U.S.C. 30122. The section provides that: A manufacturer, distributor, dealer, or motor vehicle repair business may not knowingly make inoperative any part of a device or element of design installed on or in a motor vehicle or motor vehicle equipment in compliance with an applicable motor vehicle safety standard. However, in limited situations in which a vehicle must be modified to accommodate the needs of a person with a particular disability or a person's special medical needs, NHTSA has in the past stated that it would consider violations of the 'make inoperative' prohibition as purely technical ones justified by public need, and that it would not institute enforcement proceedings. I would like to caution you that both safety belts and air bags are very important items of safety equipment. Safety belts are the primary means of occupant restraint, and work in all types of crashes. NHTSA estimates that in 1994, safety belts saved almost 9,200 lives and prevented more than 211,000 moderate to critical injuries. The combination of wearing safety belts and having an air bag installed at a seating position provides vehicle occupants with maximum safety protection in all types of crashes. Also, air bags are designed to offer some protection even when safety belts are not used. Since 1987, air bags are estimated to have saved 911 lives. NHTSA strongly encourages vehicle occupants to wear their safety belts, since we are concerned about the much higher safety risk faced by unbelted occupants. We understand, however, that you cannot wear your safety belt for medical reasons, and that you are concerned about a possible safety risk from the air bag in such a situation. While air bags have an impressive overall performance record and are designed to provide some protection even for unbelted occupants, NHTSA has become aware of situations in which current air bags have undesired side effects. These include situations in which an air bag appears to have contributed to serious injuries and even death to vehicle occupants, in minor-to-moderate severity crashes. Information indicates that an air bag might pose a risk of serious injury to unrestrained small statured and/or older people, in particular. I note that NHTSA has recently issued a request for comments (copy enclosed) concerning the agency s actions to minimize the adverse side effects of air bags and to invite the public to share information and views with the agency. Since your disability prevents you from wearing your safety belt, and given your age and size, the disability places you in a situation where there may be a risk of serious injury from the air bag. While this particular risk can be addressed by disconnecting the air bag, there are trade-offs: Disconnecting the air bag subjects you to a higher risk in crashes, especially higher-speed crashes, where the air bag would provide protection. We urge you to carefully weigh the trade-offs in making your decision. If you decide that the risk to you from the air bag offsets the potentially life-saving benefits of the air bag, and you wish to have your air bag deactivated, we would regard the deactivation a purely technical violation of the 'make inoperative' prohibition justified by public need. Accordingly, we would not institute enforcement proceedings against any person listed in section 30122 who deactivated the air bag. I would recommend that the manufacturer of the vehicle and/or air bag be consulted on the safest way to disconnect the air bag. I also note that the air bag should only be disconnected from a position where you would be seated. In addition, I strongly encourage you to ensure that every person in your vehicle who can use his or her safety belt does so. I want to add a caution. The purpose of the 'make inoperative' prohibition is to ensure, to the greatest degree possible, current and subsequent owners and users of your vehicle are not deprived of the maximum protection afforded by the vehicle as newly manufactured. Accordingly, if you were to sell your vehicle later, we urge that the air bag be reactivated for the subsequent driver. I hope that this letter resolves your problem. If you have any other questions, please contact Edward Glancy of my staff at this address or by phone at (202) 366-2992. Sincerely, Samuel J. Dubbin Chief Counsel Enclosure"; |

ID: aiam5631OpenHugh J. Bode, Esq. Reminger & Reminger The 113 St. Clair Building Cleveland, OH 44114; Hugh J. Bode Esq. Reminger & Reminger The 113 St. Clair Building Cleveland OH 44114; "Dear Mr. Bode: This responds to your letter concerning whether 4 U.S.C. 30101 et seq. (formerly the National Traffic and Motor Vehicle Safety Act) requires a motor vehicle manufacturer to ensure that its vehicle continues to comply with applicable Federal motor vehicle safety standards (FMVSSs) after the first retail purchase of the vehicle. You specifically ask about FMVSS No. 124, 'Accelerator Control Systems,' and its application to a 1988 Dodge Ram 50 pickup truck. It appears from the questions you ask that corrosion developed inside the carburetor of the pickup truck at some point during the life of the vehicle, such that the carburetor would not return to idle in accordance with the requirements of Standard No. 124. You asked us to 'confirm the accuracy' of a number of statements. Your first statement, concerning the application of the FMVSSs generally, is as follows: As we understand it, former 108(a)(1)(A) of the National Traffic and Motor Vehicle Safety Act, 49 U.S.C. 30112(a), prohibits any person from manufacturing, selling or introducing into commerce any new motor vehicle unless the vehicle is in conformity with all applicable FMVSS. However, the Safety Act further provides that the requirement that a vehicle comply with all applicable FMVSS does not apply after the first purchase for purposes other than resale, i.e., the first retail sale of the vehicle. Safety Act former 108(b)(1), 49 U.S.C. 30112(b)(1). After the first retail sale, the only provision in the Safety Act that affects a vehicle's continuing compliance with an applicable FMVSS is set forth in former 108(a)(2)(A), 49 U.S.C. 30122(b), which prohibits certain persons from knowingly rendering inoperative a device installed in a motor vehicle in compliance with an applicable FMVSS. Your general understanding is correct. However, a manufacturer has responsibilities in addition to those in 30112, that may bear upon on 'continuing compliance' of its vehicle. Under 30118-30122 of our statute, each motor vehicle manufacturer must ensure that its vehicles are free of safety-related defects. If NHTSA or the manufacturer of a vehicle determines that the vehicle contains a safety-related defect, the manufacturer must notify purchasers of the defective vehicle and remedy the problem free of charge. This is not to say that the development of the corrosion in the carburetor necessarily constitutes a safety-related defect. Rather, we acknowledge the possibility of such a finding in certain circumstances, such as where the corrosion developed unreasonably quickly in the vehicle and the problem was such that it could lead to crashes involving injuries or fatalities. State law could also be relevant to this issue. For example, as part of its vehicle inspection requirements, a State could require that the accelerator control systems on vehicles 'continue to comply' with the requirements of Standard No. 124. With the above discussion in mind, I will now address your other four questions on Standard No. 124. Question 1. We ask that NHTSA confirm that FMVSS 124 is a standard that a given vehicle must comply with only at the time of the first retail sale of the vehicle. As explained in our answer above, your understanding is correct with regard to our requirements (49 U.S.C. 30112). There may be State requirements that apply. Question 2. We ask NHTSA to confirm that if a carburetor installed in a 1988 Dodge Ram 50 pickup truck met all the requirements of FMVSS 124 at the time of the truck's first retail sale, but, after the sale, due to in-service conditions, corrosion developed inside the carburetor so the carburetor would not return to idle in accordance with the requirements of S5.1, S5.2, and S5.3 of FMVSS 124, that circumstance would not render the vehicle in violation of FMVSS 124. Your understanding is essentially correct. As permitted by Federal law, Chrysler sold the truck based upon its own certification of compliance with FMVSS No. 124. That corrosion developed in the system may or may not be relevant with respect to the existence of a safety-related defect. Question 3. We ask NHTSA to confirm that all of the performance standards imposed by FMVSS 124 are contained in S5.1, S5.2 and S5.3 of FMVSS 124 and that S2 headed PURPOSE does not impose any separate regulatory obligation beyond those contained in S5. While your understanding is essentially correct, note that Standard No. 124 and other motor vehicle safety standards are minimum performance standards. Question 4. We ask you to confirm that the performance standard set forth in FMVSS 124 does not contain any requirement relating to durability or corrosion resistance. Standard No. 124 does not specify a test for corrosion resistance. It is unclear what you mean by 'durability.' The requirements of the standard must be met when the engine 'is running under any load condition, and at any ambient temperature between -40 F. and +125 F. ....' (S5) In addition to the performance regulated by Standard No. 124, each manufacturer must ensure that its motor vehicle does not have a safety-related defect. If you have any questions about the information provided above, please contact Dorothy Nakama of my staff at this address or at (202) 366-2992. Sincerely, John Womack Acting Chief Counsel"; |

ID: aiam3454OpenMr. V. J. Adduci, Motor Vehicle Manufacturers Association, Suite 300, 1909 K Street, N.W., Washington, DC 20006; Mr. V. J. Adduci Motor Vehicle Manufacturers Association Suite 300 1909 K Street N.W. Washington DC 20006; Dear Mr. Adduci: On June 5, representatives of MVMA met with representatives of thi agency to discuss various issues concerning the application of Federal Motor Vehicle Safety Standard No. 115. At that meeting, the MVMA representatives requested clarification of the agency's policy on correction of errors made by vehicle manufacturers in their vehicle identification numbers (VIN's). This letter responds to that request.; The agency shares your concern about the potential difficultie associated with correcting erroneous VIN's and will attempt to minimize the burdens involved with any required corrective action. Nevertheless, the agency must consider the safety benefits of an accurate, national VIN system, as well as the anti-theft and other benefits of such a system.; This letter focuses on some of the most likely VIN errors and discusse whether those errors in vehicles sold to consumers would be inconsequential as the errors relate to safety, and, if not, what type of remedy would have to be provided to vehicle owners. Corrective action involving the replacing of an erroneous VIN plate or label or the restamping of the VIN on part of the vehicle is the most desirable remedy. However, there may be less burdensome remedies that would be effective and satisfy the National Traffic and Motor Vehicle Safety Act.; One type of error which could be easily corrected is an error in single VIN character other than the check digit or a character monitored by VIN users. The agency would likely regard such an error as inconsequential if the vehicle manufacturer submitted the necessary corrected decoding information to the agency. The agency would place this information in a public file, thereby making it available to other VIN users. With this corrected decoding information available, the agency's safety research activities would not be impaired and manufacturers would still be able to conduct recall campaigns where necessary.; A second type of error involves an erroneous check digit or othe character monitored by vehicle records systems of States or other VIN users. Erroneous check digits could adversely affect our ability to conduct research and to monitor recalls, since the error rate of VIN transcription would presumably be higher in the absence of a properly functioning check digit. Further, without some form of corrective action by the manufacturer (such as restamping or the use of a correction label), vehicle purchasers could face rejections by State, insurance, and other data-processing systems using the check digit to verify transcription accuracy. However, the agency is also concerned that the use of labels could create opportunities for auto theft operations to generate bogus VIN's. Therefore, the agency is presently inclined to treat erroneous check digits as inconsequential noncompliance if the manufacturer reports the errors to the agency. However, as discussed below, the agency is planning to invite public comment on this question before establishing a final position on the matter.; A third type of error involves the physical aspects of the VIN itself For example, a manufacturer might use a type face other than the sans serif type face required by the standard. Although errors of this type would have to be resolved on a case-by-case basis, they would likely be deemed inconsequential because they would present no problems to the agency, other VIN users, or vehicle owners.; The most difficult type of errors would involve a major error i numbering which would impair the safety and other uses of the VIN. An extreme example of such an error would be a situation where a manufacturer numbered many of its vehicles identically, or where the VIN's were totally illegible. An error of that magnitude could impair the manufacturers' (sic) ability to conduct recall campaigns and the ability of the agency to monitor them. It would also cause serious problems for all VIN users. In this type of situation (which should arise rarely, if ever), some form of corrective action would be necessary. The use of a correction label which meets all requirements of FMVSS 115 including indelibility would be one possible approach.; One final matter discussed at the June 5 meeting relates to th correction of VIN errors on vehicles already produced but still in the possession of the manufacturer. We would treat these vehicles the same as the vehicles already sold, i.e., if the noncompliance were inconsequential for the vehicles already sold, it would also be inconsequential for the vehicles produced but still in the manufacturer's possession. However, the agency would expect that once the error is detected, similar vehicles produced thereafter would fully comply with the standard. There is precedent for this approach, since the agency has previously treated as inconsequential noncompliance erroneous identification numbers on tires still in the manufacturer's possession, where an inconsequentiality petition has been granted with respect to tires already sold.; The agency will issue in the near future a notice inviting comment o MVMA's petition to change Standard 115 to a general regulation. In this notice, we will seek comment on the types of corrective action discussed above. If you have any thoughts on other means of making these types of corrections, we would of course be pleased to receive your views.; Sincerely, Frank Berndt, Chief Counsel |

ID: aiam3108OpenMr. Hisakazu Murakami, Nissan Motor Co., Ltd., Suite No. 1012, 1028 Connecticut Avenue, N.W., Washington, DC 20036; Mr. Hisakazu Murakami Nissan Motor Co. Ltd. Suite No. 1012 1028 Connecticut Avenue N.W. Washington DC 20036; Dear Mr. Murakami: This responds to your recent letter requesting an interpretatio concerning the proper 'designated seating capacity' for three hypothetical seat designs. You ask whether each of the designs would be permitted to have only two 'designated seating positions.'; The amended definition of 'designated seating position' provides, i part, that any bench or split-bench seat having greater than 50 inches of hip room shall have not less than three designated seating positions, unless the seat design or vehicle design is such that the center position cannot be used for seating.; Your three hypothetical designs are derived from a basic seat desig having 52 inches of hip room (Figure 1 in your letter). This basic design would be required to have three designated seating positions since it has greater than 50 inches of hip room, unless the center position cannot be used because of some obstruction or other impediment. You ask whether the agency would consider the three hypothetical designs illustrated in your letter to adequately establish impediments to use of the center position.; Your 'Figure 2' illustrates an unpadded depression at the cente position of the bench seat. Since this center depression is unpadded, 3.1 inches deep and 6.7 inches wide, it is the agency's opinion that the center position lacks an essential attribute of a seating position and would not likely be used for seating (even though there might be some unorthodox use of the position from time to time). If a seat of this design is equipped with seat belt assemblies, location of assembly hardware in the center depression would further clarify that the area is not a seating position. It must be emphasized, however, that designs of this type would be required to have three designated seating positions if the depth and width of the depression is so minimal that a person could easily straddle the depression and use the center position. Also, stiffness of seat belt assembly hardware located in the center depression becomes a more determinative factor the more narrow the width of such a depression.; The seat design illustrated in 'Figure 3' of your letter includes 'partition pipe' at the center of the seat cushion. Whether such a design would preclude the use of the center position would depend greatly on the physical dimensions and characteristics of the 'pipe' that is used and whether it is removable. If the 'pipe' were made of soft, pliable padding similar to the other portions of the seat, for example, the 'pipe' might not be sufficient to discourage use of the center position. Since your letter provides no information on the nature of the 'partition pipe' that is illustrated, the agency cannot offer an opinion concerning this design.; In 'Figure 4,' there is a padded 'swelling' in the center sea position. Although the Figure specifies a height of 3.9 inches at the front of the 'swelling,' it appears that the 'swelling' slants down toward the seat back so that it is only about one-half inch high where it joins the seat back. The illustration also does not describe whether the 'swelling' is made of soft padding or of some rigid material. Without this information, the agency cannot offer an opinion concerning this design. I would point out, however, that if the 'swelling' is made of soft, flexible padding, it would not likely discourage use of the center position. In fact, if as it appears the 'swelling' slants down to the seat back to create a 'saddle effect,' young children might be encouraged to use this center position.; To summarize, it is the agency's opinion that 'Figure 2' in your lette illustrates a seat design that could qualify as having two designated seating positions. Regarding Figures 3 and 4, your letter did not include sufficient information for the agency to provide an opinion. On the basis of the information that was provided, however, I would say that these two designs are very dubious and do not indicate an adequate attempt on the part of the manufacturer to clarify that the center position is not to be used. It does not behoove a manufacturer to attempt to come narrowly within the meaning of the amended definition of 'designated seating position.' It would be much wiser to make sure that there is no question that the center position is not to be used. In the design illustrated in your 'Figure 4,' for example, you could easily design the 'swelling' to be 4 or more inches tall from front to rear and made of a rigid material, and there would be no question concerning your compliance.; Finally, I would emphasize that this letter only represents th agency's opinion based on the information supplied in your letter. The NHTSA does not pass approval on any vehicle design, for any safety standards, prior to the actual events that underlie certification. It is up to the manufacturer to determine whether its vehicles comply with all applicable safety standards and regulations, and to certify its vehicles in accordance with that determination.; Sincerely, Frank Berndt, Chief Counsel |
