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.

Dear Mr. Reider: This is in reply to your letter of October 14, 1977, to Don Williamso of our Ohio regional office.; You enclosed information on an automatic warning flasher lamp that i designed for installation on the parcel shelf inside the rear window of automobiles. You asked whether such a device would be legal on U.S. cars or U.S. highways, and 'what steps might be required to obtain an endorsement for the generic device from the N.H.T.S.A.'; The unit appears to be designed for sale as a motor vehicle accessor in the aftermarket. There are no Federal prohibitions against the sale of the warning device or its installation in motor vehicles. Whether it is legal to use such a device however is a question to be answered under the laws of the jurisdiction where the motor vehicle in which it is installed is registered and/or operated.; The NHTSA does not issue approvals or endorsements of propriety safet devices.; Yours truly, Frank Berndt, Deputy Chief Counsel

Dear Mr. MacCleery: This is in reply to your letter of March 3, 1972, in which you asked t be referred to the information on which we based our statement in the notice of February 24, 1972, that systems meeting the injury criteria of Standard 208 are available using current seat belt technology.; Research data on the capabilities of seat belts are found in severa places in the public docket, notably in the progress reports from our Safety Systems Laboratory and from Cornell Aeronautical Laboratory (69-7 General Reference Nos. 74, 75, 83, 96, 102, 117, 120 and 135). There are records of vehicle tests in which current lap and shoulder belt systems have met the injury criteria (see, e.g. N13-69-7-20, N13-69-7-37). Also, the record contains information on energy absorbing webbing and anchorages, both of which are improvements within the current state of the art (see, for example, the 6th progress report from Cornell, runs no. 625-630, 69-7 General Reference No. 135, the data from Toyota in N13-69-7- 23, and the Takata Koyjo data in N16-69-7-1).; Although the behavior of the head seems to be a greater problem fo belt systems than the behavior of the chest, due in part to the effects of rebound, we have proposed changes in the head injury criterion that should ease the problem considerably.; Sincerely, Douglas W. Toms, Administrator

Dear Ms. Ciani: This responds to your May 11, 1976, question whether S 574.7 of Par 574 (*Tire Identification and Record Keeping*) (49 CFR Part 574), requires that the brand name owner of a single tire brand must supply to its dealers tire registration forms that conform to the dimensions specified for the 'universal form' described in Figure 3 of the regulation. You also request confirmation that a tire registration form 'which fits credit card imprinters and provides for the registration of only two tires' is similar in format to the form described in Figure 3.; Section 574.7 of the regulation specifies in part that '. . . form conforming in size and similar in format to Figure 3 shall be provided to those dealers who request them. . . .' As stated in the preamble accompanying the requirement, the purpose of the specification is to ease the problem of the multi-brand dealer who was 'faced with a multiplicity of different forms and procedures for tire registration' (39 FR 19482, June 3, 1974). The requirement that the 'universal form' conform in size as well as format was added in conjunction with a similar requirement for dealers, in response to petitions for reconsideration of the June amendment (39 FR 28658, November 1, 1974).; Review of the changes indicates clearly that the requirement fo conformity in size of the 'universal form' was directed only to the situation of multi- brand dealers. The NHTSA does not consider the manufacturer or brand name owner of one tire brand to be subject to this requirement in the case of a dealer who sells only one brand of tires. It is clear that any advantage in the storage of different forms from different tire manufacturers would not apply in the case of a one-brand dealer. Accordingly, the NHTSA interprets S 574.7 to not require conformity in the size of forms supplied by a tire manufacturer, brand name owner, or its designee, in the case of requests from dealers that sell only one brand of tire.; In answer to your second request, the NHTSA considers a tir registration form which provides for the registration of only two tires to be similar in format to the form described in Figure 3. Any variation from the size of the form described in Figure 3 would, of course, be subject to the limitation just discussed.; Sincerely, Frank A. Berndt, Acting Chief Counsel

"Mr. Ashpy Lowrimore Senior Vice President Southern National Bank P.O Box 6676 Florence, SC 29502 Dear Mr. Lowrimore: This responds to your August 11, 1994 letter regarding our requirements for school vehicles. You explain that your church owns a 'commercial bus' and a 15-passenger van and would like to use these vehicles to transport children attending a kindergarten and after school care program that the church operates. You ask to be advised of any requirements applicable to those two vehicles, and have three questions, which I will answer below. I would like to begin with background information about our requirements. Our agency has two sets of regulations, issued under different Acts of Congress, that affect school vehicles. The first of these, the Federal motor vehicle safety standards (FMVSS's) issued under 49 U.S.C. 30101, et seq., apply to the manufacture and sale of new motor vehicles. Our agency was directed by Congress in 1974 to issue standards on specific aspects of school bus safety, including floor strength, seating systems, and crashworthiness. The standards we issued apply to all new vehicles designed to carry 11 or more persons and sold for pupil transportation purposes. Under our requirements, such a vehicle is a 'school bus,' and any person selling such a vehicle must ensure that the new vehicle is certified as meeting the FMVSS's for school buses. The second set of regulations issued by this agency was promulgated under the Highway Safety Act of 1966. These 'regulations' are actually recommendations from NHTSA to the States for use in developing their highway safety programs. Highway Safety Program Guideline No. 17, Pupil Transportation Safety, 23 CFR 1204 (copy enclosed), applies to school vehicles, and contains recommendations for the design, identification and operation of school vehicles. Individual States have chosen to adopt some or all of Guideline No. 17 as their own policies governing their highway safety programs. With that background in mind, I turn now to your specific questions: 1. Can we transport children who are related with our various schools by utilizing the van? ANSWER: The answer depends on State law, because the States regulate the use of motor vehicles, not NHTSA. NHTSA regulates the manufacture and sale of new vehicles. Any person selling a new bus or a new 15-passenger van to your church for purposes that include transporting kindergarten students to and from school or related events must sell buses that meet our FMVSS's for school buses, or face substantial civil fines and injunctive sanctions. NHTSA does not have the authority to regulate vehicle users, and thus does not mandate what vehicle can be used to transport school children. Thus, our regulations impose no requirement on schools that require them to transport students in complying school buses. While NHTSA does not require the use of any particular type of vehicle to transport students, we believe that school buses are the safest motor vehicle transportation currently available. We have included in Guideline No. 17 a recommendation that States require any bus (or van carrying 11 or more persons) used to carry school children to comply with all FMVSS's applicable to school buses at the time of their manufacture (see, recommendation number IV.B.1.h). However, since Guideline No. 17 will affect your church's school vehicles only if South Carolina has adopted it, you should check to see what State requirements are set for the operation of the school vehicles in question. Mr. Perry Brown, Deputy Director of South Carolina's Office of Highway Safety Programs, would be able to provide information about your State's requirements. He can be contacted at the following address: Mr. Perry Brown Edgar A. Brown State Office Building 1205 Pendleton St., Rm. 453 Columbia, SC 29201 2. Are there restrictions associated with the use of the bus in the transportation of children, young adults or senior adults? As explained above, NHTSA has no restriction on the use of motor vehicles. Restrictions on the use of a vehicle are matters of State law. Among other things, the State could require a special driver's license for persons operating buses as you described. A South Carolina official would be able to provide the information you need. 3. If there are special restrictions, can you elaborate on the type of equipment that we must obtain in order to meet any regulations or requirements that are in place? ANSWER: Again, NHTSA has no restrictions on the use of the vehicles by the church. Further, NHTSA does not require schools operating their vehicles to ensure that the vehicles are specially identified or equipped as school vehicles. However, Guideline No. 17 contains recommendations for identifying school buses and equipping them with safety equipment, including school bus lamps and mirrors and emergency equipment. South Carolina may have adopted some of these recommendations in its highway safety program for school vehicles. In summary, NHTSA does not have the authority to regulate the use of school vehicles owned and operated by your church. You should check with South Carolina officials to find out which, if any, State requirements apply to your church's activities. We hope this information is helpful to you. Should you have any further questions regarding this matter, please feel free to contact Walter Myers of my staff at this address or at (202) 366-2992. Sincerely, Philip R.

Dear Mr. Colburn: This responds to your February 6, 1976, questions whether Lufki Industries may, as an incomplete vehicle manufacturer, build 'incomplete chassis trailers' that do not have brakes installed that comply with Standard No. 121, *Air Brake Systems*, and whether Lufkin may tow the 'incomplete chassis trailers' over the highway to the final-stage manufacturer without brakes that conform to Standard No. 121.; Lufkin's activities are regulated by Part 568 of Title 49 of the Cod of Federal Regulations, if the 'incomplete chassis trailers' qualify as 'incomplete vehicles.' A copy is enclosed for your information. Part 568 does not require the incomplete vehicle to meet all applicable safety standards, but S 568.4 does require a statement of the status of an incomplete vehicle's conformity with all applicable standards.; In answer to your second question, the NHTSA permits the use of a incomplete vehicle on the public highways for the purpose of transit between the incomplete vehicle manufacturer and subsequent manufacturers, but for no other purpose, until such time as the vehicle complies with all Federal motor vehicle safety standards applicable to it as completed. This ruling by the NHTSA does not relieve the manufacturer or shipper from any applicable requirement imposed on the incomplete vehicle by other Federal, State, or local authority.; Sincerely, Frank Berndt, Acting Chief Counsel

Dear Mr. Siwac: I regret our delay in responding to your letter of December 2, 1969 which evidently became lost after it reached us.; In your letter you ask three questions. The questions, and our answer to them, are as follows:; >>>1. If a European concern manufactures seat belts for installation i vehicles imported into the United States, is the vehicle manufacturer or the seat belt manufacturer responsible for compliance with Motor Vehicle Safety Standard No. 209 with respect to those seat belts? It is our view that both manufacturers are responsible for compliance with the standard. Section 108(a) of the National Traffic and Motor Vehicle Safety Act prohibits the manufacture for sale in the United States of a nonconforming vehicle or item of motor vehicle equipment. A seat belt manufactured for installation on a motor vehicle to be sold in the United States is itself manufactured for sale in the United States. The manufacturer of the motor vehicle in which the nonconforming seat belt is installed would be in violation of section 108(a) because Motor Vehicle Safety Standard No. 208 requires certain motor vehicles to be equipped with seat belt assemblies that conform to Standard No. 209.; 2. Is a foreign manufacturer of seat belts which will be imported int the United States required to test the belts at approved facilities in the United States to demonstrate that they conform to Standard No. 209? The answer is no. There is no requirement in the law or the standard that seat belts must be subjected to approved tests before they can be imported and sold. The manufacturer must certify that the belts conform to the standard. In order to do so, a manufacturer would ordinarily make tests of his products. This is particularly the case because compliance with some of the standard's requirements can be ascertained only by actual tests of seat belts. However, there is no requirement that any particular test be made at any specific test facility.; 3. Must a European seat belt manufacturer designate an agent fo service of administrative process under section 110(e) of the National Traffic and Motor Vehicle Safety Act if he is merely supplying the belts for installation as original equipment in motor vehicles to be imported into the United States. It is our view that a foreign manufacturer of motor vehicle equipment who knows or has reason to know that his products will be imported into the United States, whether as original equipment on motor vehicles or otherwise, is obligated under section 110(e) to designate an agent for service of process in accordance with that section. Section 110(e) is not limited in its scope to manufacturers who actually import their products, it also applies to manufacturers who are 'offering a motor vehicle or item of motor vehicle equipment for importation into the United States'. The quoted language seems broad enough to cover suppliers of motor vehicle equipment who know or should know that the vehicles in which their products are installed will be imported for sale into the United States.<<<; Again, let me express my apologies for the delay in responding to you inquiry. If you have any further questions about your obligations under the National Traffic and Motor Vehicle Safety Act, please do not hesitate to contact me.; Very truly yours, Lawrence R. Schneider, Assistant Chief Counsel fo Regulations;

DC 20515-4202;

Dear Mr. Duncan: Thank you for your letter enclosing correspondenc from your constituent, Mr. Clarence Lowe, an instructor for Campbell County Comprehensive High School, concerning the use of 15-passenger vans to transport school children. Campbell County has been informed by the Tennessee State Department of Education that vans cannot be used to transport children to school or school-related events. In light of school budget constraints, Mr. Lowe would like to use these vehicles for transporting students to off-campus vocational programs. Your letter also enclosed a letter from Ernest Farmer, Tennessee Director of Pupil Transportation, explaining why the State of Tennessee has instructed schools not to use vans to transport school children. I am pleased to have this opportunity to clarify Federal law as it relates to school buses. The National Highway Traffic Safety Administration (NHTSA) has the authority under the National Traffic and Motor Vehicle Safety Act to issue motor vehicle safety standards that apply to the manufacture and sale of new motor vehicles, in order to reduce the number of fatalities and injuries that result from motor vehicle crashes. Under NHTSA's regulations, vans are generally classified as either multipurpose passenger vehicles (MPV's) or buses. The MPV category includes vans which carry 10 persons or less, vans which carry more than 10 persons are buses. Thus, the 15-passenger vans referred to by Mr. Lowe are classified as buses. Under the agency's definitions, a 'school bus' is a type of bus sold for transporting students to and from school or school-related events. All MPV's and buses are required to meet Federal motor vehicle safety standards. However, in the legislative history of the School Bus Safety Amendments of 1974, Congress stated that school transportation should be held to the highest level of safety. Accordingly, NHTSA has issued special Federal motor vehicle safety standards applicable to all new school buses. Like all safety standards, NHTSA's school bus standards impose obligations on the manufacturers and sellers of new motor vehicles, not upon the subsequent users of these vehicles. It is a violation of Federal law for any person to sell any new vehicle that does not comply with all school bus safety standards if the vehicle capacity is more than 10 persons, and if the seller is aware that the purchaser intends to use the vehicle as a school bus. On the other hand, without violating any provision of Federal law, a school may use a vehicle which does not comply with Federal school bus regulations to transport school children. This is so because the individual States, not the Federal government, have authority over the use of vehicles. However, I would like to call your attention to a guideline that NHTSA has issued under the authority of the Highway Safety Act of 1966. That Act authorizes the agency to issue guidelines for states to use in developing their highway safety programs. NHTSA issued Highway Safety Program Guideline 17, Pupil Transportation Safety, to provide recommendations to the states on various operational aspects of their school bus and pupil transportation safety programs. Guideline 17 recommends that any vehicle designed for carrying more than 10 persons which is used as a school bus comply with all safety standards applicable to school buses at the time the vehicle was manufactured. In conclusion, it is not a violation of Federal law for Campbell County to use its 15-passenger vans for transportation of school children, however, use of these vehicles may be restricted by Tennessee law. I must emphasize NHTSA's position that a vehicle meeting Federal school bus regulations is the safest way to transport students. Despite the additional cost of these vehicles, I encourage Campbell County to give its most careful consideration to the possible consequences of transporting students in vehicles that do not comply with these regulations. I hope this information is helpful. Sincerely, Jerry Ralph Curry;

Dear Bill: This is in reply to your letter of February 14, 1973, forwarding to m a copy of the preface to your forthcoming paper on the development of Standard No. 213, and asking a few questions which we have already discussed over the phone.; With respect to the preface, it is essentially accurate, at leas sufficiently so for the purpose for which it is intended.; The questions you've asked are repeated below, followed by our answers. 1.>>>What gives credibility to and what reduces credibility of comment filed with Docket 2-15? Are the comments of some organizations given more credence than others?<<<; Each comment to the docket is assumed to be of equal credibility tha is, we assume each is offered in good faith, and based upon the writer's legitimate beliefs and interests. The agency evaluates each submission on its own merits.; 2.>>>Do non-separating 3-point belts present a problem for usage o current child restraint systems?<<<; Our understanding is that child seats can be used with 3-point belts These belt systems do utilize one member that is essentially similar to the traditional lap belt. We understand the shoulder portions of these belts can be adjusted so as not to prevent installation of the child seat, by either placing that belt section in front of or behind the child seat. We have not received any information from the public that these belts are in fact difficult to use with child seats. If we do we will certainly look into the matter thoroughly.; 3.>>>Has NHTSA or will NHTSA be cooperating with JPMA on some kind o market survey?<<<; The NHTSA has forwarded a list of suggested questions, which are als in the docket. We do not expect our contribution to include more than recommending that these questions be asked.; 4.>>>To what extent is rulemaking determined by comments and b internal direction?<<<; This certainly depends on the issues involved. For the most part initial decisions are made by the agency, with modifications resulting from comments received. However, comments may affect some issues more than others. In Standard No. 213, for example, much impetus for a dynamic test has been created by comments.; We've recently amended the standard, based on two outstanding notice (September 30, 1970, April 10, 1971).

Dear Mr. Frinken: This is in response to your letter of July 20, 1979, concerning th Uniform Tire Quality Grading (UTQG) Standards (49 CFR 575.104). You ask whether it is permissible under the regulation to mold UTQG grades on only one sidewall of a tire and, in the case of a symmetrical black sidewall tire, whether the grades may be molded on the same sidewall as the tire identification number required by 49 CFR 574.5.; The UTQG Standards require that tire grades need be molded on only on sidewall of a tire. Since the regulation presently does not specify the sidewall on which tire grades must be molded, Uniroyal is legally permitted to mold UTQG grades on either sidewall of its tires. However, in order to facilitate consumer access to the grading information, the National Highway Traffic Safety Administration (NHTSA) encourages manufacturers to mold tire grades on the sidewall intended to be visible when the tire is mounted on a vehicle. NHTSA will monitor the placement of tire grades to determine whether further action is necessary to assure the accessibility of the grading information.; Sincerely, Frank Berndt, Chief Counsel

Dear Mr. Tokunaga: This responds to your letter seeking an interpretation of Part 541 *Federal Motor Vehicle Theft Prevention Standard*. Specifically, you indicated that you would like to mark the engines and transmissions of your high theft car lines by affixing metal plates with the vehicle identification number (VIN) inscribed thereon to the engines and transmissions. I will answer your questions in the order they were set forth in your letter.; 1. The VIN's are inscribed directly on parts in Isuzu's curren production. You do not think that a change from direct inscription to VIN plate affixation constitutes a violation of Part 541. Is this correct?; Yes. Section 541.5(d) specifies that required markings must 'be affixe by means that comply with paragraph (d)(1) of this section *or* inscribed by means that comply with paragraph (d)(2) of this section.' Manufacturers are free to choose whether to affix or inscribe the required markings, and are free to change that choice at any time. The only limitation set by Part 541 on this choice is that the markings that appear on the parts must comply with the requirements of either S541.5(d)(1) or (d)(2).; 2. May the 17- digit VIN be expressed in two lines, for example nin digits on the top line and eight on the bottom line?; Yes. In a June 9, 1986 to Messrs. Waimey and Hansell, I addressed thi topic as follows:; >>>In the agency's view, S541.5(b)(1) requires that the ful 17-character VIN be marked in such a way that police can easily determine what VIN is marked on the part, and then check to see if that part is stolen. If a VIN is divided into segments, the proper sequence of those segments must be readily determinable. If the VIN were placed on two lines, beginning on the first line with the remainder of the VIN directly below the first line, as suggested in your letter, we do not believe it would be confusing or difficult for law enforcement officers to easily read the marking in the correct order. Accordingly, we conclude that marking the VIN on two separate lines, with the second directly below the first, would not violate any of the requirements of Part 541.<<<; 3. As shown in the drawings attached to your letter, you are planing t affix the VIN plate carrying the inscribed VIN either by rivets or breakaway-head bolts. Part 541 specifies requirements which must be met when the VIN is affixed, in S541.5(d)(1), or when it is inscribed, in S541.5(d)(2).; 3.1 With which set of requirements should an affixed VIN plate wit inscribed markings comply?; We have stated in several past interpretations that the language o S541.5(d) means that *all* markings that are affixed to a part, whether by means of adhesive, screws, rivets, or welding, must satisfy the performance requirements for labels set forth in S541.5(d)(1). Since your VIN plate would be affixed, it would be subject to the performance requirements for labels.; 3-2-1. Section 541.5(d)(1)(i) says that the number must be printe indelibly on a label. You believe that the number inscribed on a metal plate meets this requirement. Is this correct?; Your belief is correct. The requirement that the marking be printe indelibly on a label was included in Part 541 to ensure that the markings would remain legible to investigators for as long as the label was affixed to a part. *See* 50 FR 43166, at 43170-71, October 24, 1985. Inscribing a number on a metal plate ensures that the number will be legible for the life of the metal plate, and complies with the requirement of S541.5(d)(1)(i).; 3-2-2. Since the number is inscribed on a metal plate, you believe tha subparagraphs (ii), (vii), and (viii) of paragraph 541.5(d)(1) are not applicable. Is this correct?; No, it is incorrect. *All* of the requirements of S541.5(d)(1) must b satisfied by any marking affixed to satisfy the requirements of S541.5.; 3-2-3. If this metal plate were removed from the engine o transmission, parts of the rivets or breakaway-head bolts will remain in the area where the plate was affixed. You think these pieces are 'residual parts of the label' within the meaning of S541.5(d)(1)(v)(B). Is this opinion correct?; It may be correct, but we do not have sufficient information to offe an opinion. Section 606(c) of the Motor Vehicle Information and Cost Savings Act (15 U.S.C. 2026(c)) requires each *manufacturer* to certify that its vehicles comply with the theft prevention standard. Therefore, this agency does not approve, endorse, or certify that any manufacturer's marking system complies with the theft prevention standard. We will, however, state whether a particular marking system appears to comply with the standard if we are provided with sufficient information on which to base that opinion. In this case, your letter does not give us enough information to offer an opinion.; The regulatory language of S541.5(d)(1)(v)(B) requires that removal o the label must 'discernibly alter the appearance of that area of the part where the label was affixed by leaving residual parts of the label or adhesive in that area, so that investigators will have evidence that a label was originally present.' If we are to offer an opinion as to whether your marking system satisfies this requirement, we must be able to determine what remains on the part after the affixed label is removed. Ideally, we would have several labels affixed to a metal section by the means described in your letter. We could then remove these labels and examine those areas of the metal section to which the labels were affixed to see what residual parts remained. If we are to offer an opinion on this topic, we at least need some means of determining what residual parts of these labels remain if they are removed, and whether such residual parts would give investigators evidence that a label was originally present. The drawings enclosed with your letter do not give us a means for making these determinations.; Your fourth question presented six alternative means for affixing th VIN plate. My response to these alternatives is the same as that set forth above in response to your question 3-2-3. Without additional information, I cannot offer an opinion as to whether any or all of these alternatives appears to comply with the requirements of S541.5(d)(1).; Please feel free to contact me if you have any further questions o need some additional information about our theft prevention standard.; Sincerely, Erika Z. Jones, Chief Counsel
