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.

TITLE: FMVSS INTERPRETATION

TEXT: This responds to your June 25, 1980, letter asking whether a proposed air brake system that you submitted would comply with the requirements of Standard No. 121, Air Brake Systems.

The National Highway Traffic Safety Administration (NHTSA) does not issue advance approval of systems constructed in compliance with safety standards. It is the responsibility of manufacturers to assure that their vehicles or equipment comply with the requirements of the safety standards. It is frequently impossible for the agency to tell from diagrams and descriptions of devices whether they will comply with the standards. Compliance is based upon testing and observation of the entire vehicle or piece of equipment as it is installed on the vehicle. Without the benefits of such tests, NHTSA cannot state whether your system would comply with Standard No. 121.

Our engineering staff has reviewed your letter and offers the following information. First, the standard contains no requirements for tractor protection valve control pressures. However, control pressures are usually set so that the trailer brakes apply before the tractor brakes.

Second, you asked whether it is appropriate to require the release of parking brakes by pushing in both the tractor protection control valve and the park valve. The standard states that the parking brake control shall control the parking brakes of the vehicle and any vehicle it is designed to tow. The standard is silent regarding the release of those brakes.

SINCERELY,

R. H. MADISON Engineering Consultant

June 25, 1980

National Highway Transportation Safety Administration

Gentlemen:

The purpose of this letter is to request an interpretation related to compliance with FMVSS 121.

A portion of one arrangement of air brake systems is illustrated on the attached sketch. The tractor protection control valve is designed to have several features.

1. With the system fully pressurized, pulling the knob out will exhaust the tractor supply line pressure and apply the trailer emergency brakes.

2. In case of trailer breakaway, the valve knob will automatically pop out, trap approximately system pressure in the tow vehicle, exhaust the tractor supply line, and apply the trailer emergency brakes.

3. If the total system pressure drops at a relatively slow rate (less than breakaway type leakage), the valve knob will automatically pop out and exhaust the tractor supply line at a system pressure not lower than 20 psi nor higher than 45 psi. The valve can be manually pushed back in but, if the system is 20 psi or lower, the valve will exhaust the tractor supply line pressure (non over-ride function).

4. When the tow vehicle is operated without a trailer, the knob is pulled out so that the tractor supply pressure is zero.

The tractor protection valve functions as follows:

1. It has a straight through passage so that the tractor supply line pressure and the trailer supply line pressure are equal.

2. The tractor service port pressure is blocked when the supply port pressure is between 20 and 45 psi.

Question One Is:

If the tractor protection valve were designed so it automatically blocked the tractor service port when the supply port was between 5 and 10 psi (rather than 20 to 45) would this, by itself, cause the system to be in non compliance?

One rationale for considering that this system would comply is as follows.

Function Present Proposed a) Tractor protection control 45 to 45 to valve automatically exhausts 20 psi 20 psi the supply pressure to the tractor protection valve. b) Tractor protection valve 45 to 10 to automatically blocks 20 psi 5 psi the trailer control port. c) Manual override of the 20 psi 20 psi tractor protection control valve is not possible below.

In both cases, when system pressure is reduced to 20 psi, the trailer emergency brakes are applied and the trailer control pressure port is blocked. The automatic operation of the tractor protection valve at 45 to 20 psi is redundant because the supply pressure to it goes to zero at not lower than 20 psi by the non override function built into the tractor protection control valve. The only difference in system performance would be the small increment of time required for the tractor protection control valve to deplete the supply pressure to the tractor protection valve from 20 psi to a range between 10 and 5 psi. System protection would still be provided by the tractor protection control valve at a supply line pressure of 20 psi or less.

Question Two Is: With the system described above (automatic operation at 10-5 psi), would a further modification, by itself, cause non compliance?

With this second proposal the park valve would apply the tractor and trailer parking brakes in the normal manner. Release would require that both the park valve and the tractor protection control valve be pushed in.

Mr. Stephen E. Mulligan International Harvester 4O1 North Michigan Avenue Chicago, IL 60611

Dear Mr. Mulligan:

This is in response to your letter of October 1, 1980, in which you ask whether compliance with 49 CFR 567, Certification, will satisfy the requirements of S4.3 of Federal Motor Vehicle Safety Standard No. 115, 49 CFR 571.115.

Section 4.3 of Federal Motor Vehicle Safety Standard No. 115 requires that the vehicle identification number (VIN) "appear clearly and indelibly upon either a part of the vehicle other than the glazing that is not designed to be removed except for repair or upon a separate plate or label which is permanently affixed to such a part." S4.3.1 requires each character to appear in a capital, sans typeface. In the case of passenger cars and trucks of 10,OOO pounds or less GVWR, each character must have a minimum height of 4 mm. s4.4 specifies that the VIN for passenger cars and trucks of 10,000 pounds or less GVWR shall be located within the passenger compartment.

Section 567.4 of Part 567, Certification (49 CFR 567), requires that the certification label be permanently affixed to the vehicle, and display the vehicle identification number. Consequently, for all vehicles except passenger cars and trucks of lO,OOO pounds or less GVWR, compliance with S 567.4 of Part 567 would also effect compliance with S4.3 of Standard No. 115 so long as capital, sans typeface was used.

Sincerely,

Frank Berndt Chief Counsel

October 1, 1980

Mr. Frank Berndt U.S. Department of Transportation Office of the Chief Counsel National Highway Traffic Safety Administration 400 7th Street, S.W. Washington DC 20590

Dear Mr. Berndt:

I am writing to request clarification of requirements which arise under Part 567 - Certification. S 567.4 requires each manufacturer of motor vehicles to affix to each vehicle a label which shall be permanently placed so that it cannot be removed without destroying or defacing it. The label is required to contain the vehicle identification number (VIN).

Federal Motor Vehicle Safety Standard No. 115 requires that each vehicle manufactured have a VIN which shall appear clearly and indelibly upon either a part of the vehicle or upon a separate plate or label permanently affixed to such a part.

International Harvester Company requests confirmation that compliance with the certification label requirements of Part 567 insures that there is also compliance with the VIN requirements set forth in FMVSS 115.

Thank you for your time and attention to this matter.

Very truly yours,

TITLE: FMVSS INTERPRETATION

TEXT: This responds to your October 31, 1980, letter asking a question about the appropriate test force for school bus seat belts. In particular, you ask whether seat belts mounted on a seat frame that employ a common U-Bolt would be tested separately or simultaneously.

As you are aware, the agency issued an interpretation stating that for purposes of complying with Standard No. 222, School Bus Passenger Seating and Crash Protection, seat belts mounted on a school bus seat frame can be tested separately as long as they have separate anchorages. In that interpretation, the agency indicated that it would not consider the seat to be a common anchorage when testing school bus seat belts.

If I understand your letter correctly, your seat frame has separate anchorage holes in it. However, the inside portions of the two seat belt systems would be tied together by a common U-Bolt. If this is the means by which you will manufacture your school buses, the seat belts must be tested simultaneously. The use of the U-Bolt provides a common anchorage between the two seat belt systems which require simultaneous testing.

Dear Mr. Tilton:

I am requesting further clarification on FMVSS Standard 222, school bus seating, in the area of seat belt load requirements as outlined in FMVSS Standard 210.

It is my understanding that the simultaneous load testing for two passenger seats is not required but that the 5,000-pound force must be tested at each seating position as long as each seating position provides its own anchorage holes for seat belt mounting.

The clarification of this ruling I am requesting is: on a two-passenger seat, in the metal frame construction, there are holes or provisions for individual mounting of seat belts. If a person mounted these two seat belts in the center by means of a "U-Bolt" sliding the belts on the "U" and then attaching the two nuts, would this means still fall under the above mentioned requirements?

TEXT: This is in response to your letter of October 20, 1980, concerning Federal Motor Vehicle Safety Standard No. 115, Vehicle identification number (49 CFR 571.115).

Your question concerns the submission of horsepower data to the agency as required by the standard (S4.5.2). On February 25, 1980, the agency published an amendment to Standard No. 115 in the Federal Register (45 FR 12255) which authorized slight variations between the engine horsepower encoded in the vehicle identification number (VIN) and the actual engine horsepower. Except in the case of motorcycles, a variance in horsepower of plus or minus 10 percent was authorized. You wish to know whether the engine horsepower data you submit to the agency should be consistent with the VIN coding, or whether you should submit the precise horsepower.

The information which must be submitted pursuant to S6.3 is that necessary to decipher the characters contained in the VIN. Consequently, the engine horsepower submitted should represent the horsepower actually encoded in the VIN, whether or not this is the precise horsepower.

TO: Volkswagen of America Inc.

TITLE: FMVSR INTERPRETATION

TEXT: This is in reply to your letter of October 28, 1980, enclosing a letter to the Environmental Protection Agency asking several questions about the relationship of your operation to the joint importation regulations.

As you have explained it the facts appear to be these: Volkswagen of America (VWoA) imports certain items of motor vehicle equipment which are incorporated together with parts of domestic manufacture into automobiles manufactured in the United States. As the components do not enter the "U.S. Customs Territory" en route to the plant, which is in a Foreign Trade Subzone, HS-7 forms are not provided at time of importation, but are furnished to Customs on a weekly basis together with formal Consumption Entries. You have asked

1) Must we file a [HS-7 Form] with each Consumption Entry?

The answer is no. Under the joint Custom-DOT importation regulation, 19 CFR 12.80(b), declarations are required for equipment items "offered for introduction into the Customs Territory of the United States." Such an introduction might be deemed to occur upon entry into interstate commerce of the motor vehicle incorporating the parts shipped from abroad (i.e. when it leaves the Subzone). But since the vehicle itself must be certified as meeting all applicable Federal motor vehicle safety standards we see no useful purpose to be served by requiring VWoA to submit HS-7 Forms for these parts, no matter what forms are required by other Federal agencies.

2) Do we have to amend previously filed forms?

For the reasons indicated in reply to your first question there is no need for VWoA to continue burdening either itself or this agency with these forms, amended or otherwise.

3) Do we have to enter "pilot vehicles" under a Customs Temporary Importation Bond (T.I.B.) Entry, or can we pay duty on them when they are withdrawn from the Subzone?

This question which you asked EPA has no apparent applicability to our regulations and I surmise that you are asking whether you must file a HS-7 Form with pilot vehicles and at what point is the filing appropriate.

No filing is necessary -- We understand the "pilot vehicle" to be a pre-production prototype manufactured in the New Stanton plant. Although that plant may be outside the Customs Territory of the United States for purposes of Customs regulations, it is within the "United States" under the National Traffic and Motor Vehicle Safety Act. Therefore when the vehicle leaves the Subzone, it is not "imported" into the United States and no HS-7 Form is required. Driving the pilot vehicle on the public roads outside the Subzone, however, introduces it into interstate commerce and it must comply with all applicable Federal motor vehicle safety standards if VWoA is not to be in violation of Section 108(a)(1)(A) of the Act (15 U.S.C. 1397(a)(1)(A)).

I hope this answers your questions.

Robert Marconi Attorney for the Investigations/Imports Section Manufacturers Operations Div. (EN-340) Environmental Protection Agency

Dear Sir:

This will serve to confirm our telephone conversation during the week of October 6, 1980. As discussed, our Westmoreland Assembly Plant is a Foreign Trade Subzone (#33A), and we have some unique problems. Possibly some background information would be helpful for you to better answer our questions.

Our Subzone was activated on January 2, 1979. We receive both foreign and domestic automotive components to be assembled together to produce our vehicles. The majority of the foreign components move from the U.S. ports of arrival "in bond" to the plant. Such parts do not enter into the "U. S. Customs territory." After our vehicles are produced, they are withdrawn from the Subzone and at that time, they enter into the "U. S. Customs territory." Each day we submit to Customs a request to withdraw vehicles produced for domestic consumption. This is done on a CF 215, and attached thereto are the specific vehicle VIN numbers. (A separate CF 215 and VIN listing is filed for automobiles and automobile trucks.) Weekly, we prepare formal Consumption Entries (CF 7501) and submit them along with the EPA (3520-1) and DOT (HS-7) forms, which includes VIN listings previously filed with the respective CF 215s. For automobiles we pay duty on the composite foreign material content at the automobile duty rate. We pay duty on the individual foreign components at their various part tariff rates for automobile trucks. Vehicles exported from the Subzone under Transportation and Exportation Bond Entries (CF 7512) do not enter the "U. S. Customs territory," and no duties are paid and would not be reported to Customs on a CF 215 nor to EPA. Hopefully, this has given you some insight on our operations. If more details are required, please feel free to contact me.

Our inquiry covers three (3) situations, and the first two are somewhat related. The questions under discussion are as follows:

1) Must we file an EPA form 3520-1 with each Consumption Entry? Normally, vehicles produced outside of the United States and subsequently imported, require the filing of the EPA form. However, even though our vehicles have not entered the legal "U. S. Customs territory" until they are withdrawn from our Subzone for domestic consumption, they are still considered as being manufactured within the United States. U. S. Customs themselves have no problem with us not submitting these documents since they are only administratively handling your regulatory requirements for Consumption Entries covering motor vehicles.

2) Do we have to amend previously filed forms?

For Model Year 1980 (i.e. August. 1979 thru August, 1980), we produced 246,111 vehicles. Our initial analysis indicates that we reported only 245,995 to Customs, EPA and DOT. Therefore, it appears that 116 vehicles (VINs) which are a combination of automobiles and automobile trucks, have not been declared. A portion of these vehicles may have been properly exported plus entered under Customs Temporary Importation Bond (T.I.B.) Entries, and therefore, not reflected on CF 215, EPA and DOT documentation. To qualify what automobile and/or automobile truck was not reported on what date and applicable EPA and DOT form would be very time consuming and costly. Therefore, we make a proposal to submit for Model Year 1980 a complete VIN listing and identify those exported or entered under T.I.B. versus amending each EPA/DOT form. Also, please accept this as an alternate proposal for future Model Years instead of filing EPA/DOT forms on a weekly basis with our Consumption Entries.

3) Do we have to enter "pilot vehicles" under a Customs Temporary Importation Bond (T.I.B.) Entry or can we pay duty on them when they are withdrawn from the Subzone?

As with all automotive manufacturers, we produce a limited quantity of preproduction "pilot vehicles." We had seventy (70) for Model Year 1980 and forty-seven (47) for Model Year 1981. They are normally used for testing, evaluation, advertising, etc. It has been our normal practice to enter these vehicles under T.I.B. Entries. However, we would prefer to pay duty on them when they are withdrawn from the Subzone. Again, U. S. Customs has no problem with us paying duty on these vehicles versus entering them under T.I.B. Entries.

Your prompt consideration to our questions and proposals would be greatly appreciated. If you should have any questions, please do not hesitate to contact me at (412) 696-6358.

TEXT: The Office of Vehicle Safety Compliance has asked me to respond to your October 14, 1980, letter asking for a clarification of the basis upon which it was suggested that your wheel spinners may not be in compliance with Safety Standard No. 211, Wheel Nuts, Wheel Discs, and Hub Caps.

Standard No. 211 prohibits the manufacture or assembly of wheel nuts, wheel discs and hub caps that incorporate winged projections. This safety standard has been in effect since 1968 and was implemented at that time, because it was determined that these devices presented potential safety hazards to pedestrians and to cyclists. Prior to 1968, manufacturers were constructing devices with winged projections that extended quite far from the wheel. To prevent this from arising again, the agency issued the standard prohibiting the manufacture of all such devices.

From reviewing the wheel spinner that you are producing, our technical staff has concluded that it incorporates a winged projection of the type prohibited by the standard. Accordingly, our staff notified you of your possible noncompliance. I trust that this clarifies the basis of our investigation. Any questions that you have with respect to this possible noncompliance should be referred to our Office of Vehicle Safety Compliance.

Pursuant to your request, the National Highway Traffic Safety Administration will provide confidential treatment, subject to the limitation of 15 U.S.C. 1418(a)(2)(B), for the total production figure in paragraph 4 of your October 14 letter.

You have first asked whether door handles are a part of the vehicle to be included in the definition. The answer is that they need not be included. The definition in 49 CFR 571.3(b) excludes outside rearview mirrors and other equipment items in computing "overall vehicle width." Although the definition does not list door handles among the equipment to be excluded in determining the nominal design dimension of the widest part of the vehicle, they are substantially similar in character to outside rearview mirrors and the other equipment items listed and may be deemed included.

Your second question is whether vehicles, whose tolerances are such that they are less than 80 inches in overall width, must nevertheless be equipped with clearance and identification lamps if the basic vehicle design is such that the "nominal design dimensions of the widest part of the vehicle" is 80 inches or greater. The answer is yes. If the engineering drawings, etc. of the basic vehicle design posit an overall vehicle width of 80 inches or more, all vehicles manufactured on the basis of that specification must be equipped with clearance and identification lamps even if an occasional vehicle is produced whose overall width may be slightly less than 80 inches due to the tolerances involved.

Subject: FMVSS108 Interpretation

File: S203.108

Dear Mr. Berndt:

IVECO Trucks of North America is a wholly owned subsidiary of IVECO, (Industrial Vehicles Company) B.V. of Amsterdam, Holland. As such we act as importers into the United States of two lines of trucks. One of these lines is the new IVECO Z Range built in Brescia, Italy. It is with regard to this vehicle that we have some questions concerning FMVSS108 and request an offical interpretation. In particular, FMVSS108 makes a basic division of vehicle lighting requirements by "overall vehicle width" defined in 40 CFR, Part 571.3, Definitions. The current definition to the best of our knowledge is: "Overall vehicle width means the nominal design dimension of the widest part of the vehicle, exclusive of signal lamps, marker lamps, outside rearview mirrors, flexible fender extensions, and mud flaps, determined with doors and windows closed and the wheels in the straight ahead position."

With regard to this definition:

1) Are door handles to be considered as a part of the vehicle to be included in the "overall vehicle width" or is the intent of the definition to take into account only the major body structure as would seem to be indicated by the list of exceptions?

2) If a vehicle were designed such that the "nominal design dimensions of the widest part of the vehicle" was above 80 inches, but the tolerance was such that specific vehicles might in reality be manufactured below 80 inches.

a) Do such vehicles, which physically measure under 80 inches, require the marker/identification lamps per greater than 80" width requirements or should they more properly meet the lighting requirements for vehicles under 80"?

In affect, what is the meaning of "nominal design width" and how does it relate to compliance of vehicles which physically meet one criteria while technically appear to meet another.

These questions are of great concern to us, therefore we would appreciate as prompt an interpretive reply as possible. If clarification or additional information is required, please do not hesitate to call me at the above address and phone number. If a meeting is deemed necessary, I am likewise available. Thank you for your assistance.

TEXT: This responds to your October 28, 1980, letter asking whether Standard No. 217, Bus Window Retention and Release, requires that there be an aisle to provide access to a side exit. The answer to your question is no.

Standard No. 217 states that side emergency exits on school buses must have an opening of 45 by 24 inches. The standard further states that a vertical transverse plane tangent to the rear most point of a seat back shall pass through the forward edge of the emergency exit. These requirements mean only that the size of the opening must be 45 by 24 inches, and that the opening must be located in a specific place with reference to the seat back.

The Federal government does not require an aisle or other access to a side emergency exit. Although some seats may partially block a side emergency exit, it can still be used for emergency exit purposes and is supplementary to a rear emergency exit. The agency adopted this approach to side emergency exits as a balance between the desire for additional exits in school buses and the need to maintain the fullest possible seating in school buses as well as the proper seat spacing.

A State is permitted to require an aisle leading to the side exit if the State determines that this is an area that it would like to regulate. Such a regulation would not be preempted, because the Federal government does not regulate the placement of aisles in buses. However, the required seat spacing would need to be retained. This means that the seat behind the aisle leading to a side emergency exit would need to have a restraining barrier placed in front of it. The net effect of the aisle and the restraining barrier could be a substantial loss of seating capacity.

Dear Mr. Shannon:

I am writing to you reference our conversation about the 1980 Thomas School Bus Body with the Side Emergency Door. I have enclosed pictures and a sketch with measurements.

In further inspection of this Emergency Door, I find it quite difficult to exit, especially if you are sitting in the seat located in the door opening. (The State of Wisconsin Rule MVD 17 requires a 12 inch aisle to the Emergency Door zone.)

I am interested in the application of your Standard No. 217, Section S5.4.2.1 (b) which reads: In the case of a side emergency door, an opening at least 45 inches high and 24 inches wide. A vertical transverse plane tangent to the rearmost point of a seatback shall pass through the forward edge of a side emergency door. Does this mean that there must be an opening with access or does it mean that there must only be an opening in the side of the bus that size? The seat blocks this emergency door opening so that there is not an opening 45 inches by 24 inches.

Thank you for your interest and attention and if I can be of further assistance, please contact me.

TITLE: FMVSS INTERPRETATION

TEXT: This is in response to your letter of November 26, 1980, to Mr. Schwartz of my office concerning Federal Motor Vehicle Safety Standard No. 115, Vehicle identification number.

In your letter you ask whether 1981 model year vehicles produced before the effective date of the standard, September 1, 1980, need comply with the standard. It would not be a violation of Standard No. 115 to produce 1981 model year vehicles which do not comply with the standard so long as they were manufactured prior to September 1, 1980.

Sincerely,

Dear Mr. Schwartz:

This letter is in response to your telephone request concerning 1981 Datsun Models' VIN Systems (new and old).

After our plants in Japan took their summer vacation (August 9-17, 1980), Nissan produced 1981 Datsun Model Vehicles with new VIN System Numbers that have seventeen (17) characters and meet the new requirements of FMVSS No. 115, VIN which has been applied to the vehicles that have been produced on and after September 1, 1980.

However, before the summer vacation mentioned above, Nissan produced 1981 Datsun Models with old VIN System Numbers because the new machines for the New VIN Numbers were introduced into our plants during the summer vacation. There are approximately 34,430 Datsun 1981 Models with old VIN Numbers (Attachment).

Nissan has been guaranteed by the Federal Government that we are not violating the Federal Law by using the old VIN System Numbers on 1981 Model Vehicles produced before August 31, 1980.

We hope this information will be sufficient for your needs. Your taking the information mentioned above into consideration will be greatly appreciated.

Very truly yours, Hisakazu Murakami -- Washington Representative, Safety
