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: aiam3153OpenMr. W. G. Milby, Blue Bird Body Company, P.O. Box 937, Fort Valley, GA 31030; Mr. W. G. Milby Blue Bird Body Company P.O. Box 937 Fort Valley GA 31030; Dear Mr. Milby: This responds to your October 3, 1979, letter asking the Nationa Highway Traffic Safety Administration to permit the production of a limited number of school buses that do not comply with Standard No. 222, *School Bus Passenger Seating and Crash Protection*. The buses would be designed to transport severly handicapped students.; As you know, Standard No. 222 permits side-facing seats for handicappe students. However, the standard does not permit other variations of seating for the transportation of the handicapped. The agency's notice of July 12, 1976 (41 FR 28506) specifically limited its action with respect to handicapped student transportation to the provision of side-facing seats.; In your letter, you state that you intend to have forward and rearwar facing seats surrounded by a cubicle to restrain children that are severely handicapped. Since only side-facing seats are acceptable as a variation from the standard's required seating, the standard cannot be interpreted in such manner that would permit the type of seats that you propose to install in your bus. Further, according to our regulation governing exemptions from the safety standards, it would appear that you would not qualify under any of the criteria that have been established. Therefore, it would not be useful to seek an exemption or waiver from the standards.; The agency has been confronted with the special problems for th handicapped many times and in a variety of vehicles. The NHTSA realizes the special needs of these individuals and further understands that these needs require the agency to be flexible in the enforcement of standards applicable to vehicles used by the handicapped. As a result the agency has stated in the past, that it will overlook some noncompliances in vehicles that are serving the special needs of the handicapped. The agency concludes that compliance with Standard No. 222 will not be enforced in certain circumstances for buses designed to transport the handicapped.; The above exemption from enforcement of compliance with Standard No 222 is limited. The seating in such special buses must be distinctly different from that of typical school buses. For example, your placement of the seats in cubicles would provide such a distinction from normal school bus seats. The mere increase of seat spacing with the use of the traditional school seats, on the other hand, would not qualify for freedom from compliance with the standard. With respect to your bus, the agency concludes that all other passenger seats beyond these constructed in the cubicles must comply with the standard. The agency further notes that the use of this type of bus is appropriate only for the most extreme cases of handicapped transportation and is not necessary for the transportation of all handicapped.; Although it would not be required by regulation, manufacturers shoul label these unique buses for the handicapped in some manner that will identify them as appropriate only for the transportation of handicapped students and not as a regular school bus. Such a label would be important in alerting both the Federal and State government officials to the fact that this is not a regular school bus and thus might be subject to different considerations with respect to the enforcement of compliance with safety standards. You should also check with State officials to ensure that they will permit the use of such buses.; Sincerely, Frank Berndt, Chief Counsel |

ID: aiam4696OpenMs. Mary Rees D.C. (USA) Inc. 1249 Route 22 East Mountainside, NJ 07092; Ms. Mary Rees D.C. (USA) Inc. 1249 Route 22 East Mountainside NJ 07092; "Dear Ms. Rees: This responds to your letter of October 9, 1990. I your letter you ask the following questions concerning testing and certification. (1) If a manufacturer has developed an item that he feels does meet all federal safety regulations, and it is ready to be tested, how would he get it tested? Are there any forms to be filed? First, please be aware that the United States does not have an approval process. In the United States, a manufacturer of motor vehicles or motor vehicle equipment must certify that its products will comply with all applicable safety standards. Each of this agency's safety standards specifies the test conditions and procedures that this agency will use to evaluate the performance of the vehicle or equipment being tested for compliance with the particular safety standard. The National Highway Traffic Safety Administration (NHTSA) precisely follows each of the specified test procedures and conditions when conducting its compliance testing. However, the Safety Act does not require a manufacturer to test its products only in the manner specified in the relevant safety standard, or even to test the products at all. A manufacturer may choose any means of evaluating its products to determine whether the vehicle or item of equipment complies with the requirements of the safety standards, provided, however, that the manufacturer assures that the vehicle or equipment will comply with the safety standards when tested by the agency according to the procedures specified in the standard. The requirements concerning certification may be found at 49 CFR Part 567. If the agency testing shows an apparent noncompliance exists with a vehicle or item of equipment, the manufacturer is asked to show the basis for its certification that the vehicle or equipment complies with the relevant safety standard or standards. If in fact there is a noncompliance, the manufacturer is subject to civil penalties under the Safety Act unless it can establish that it exercised 'due care' in the design and manufacture of the product and in the evaluation (through actual testing, computer simulation, engineering analyses, or other means) to ensure compliance, but nevertheless did not have reason to know that the vehicle or item of equipment did not in fact comply with the safety standards. While an element of 'due care' could be the use of appropriate testing laboratories, there is no explicit requirement that testing laboratories meet specific standards. In addition, NHTSA does not approve independent testing facilities, nor will it recommend any particular testing center be utilized. Finally, manufacturers are not required to file any forms beyond the requirements of 49 CFR Part 566. This regulation requires a manufacturer to submit its name, address, and a brief description of the items of equipment it manufactures, there is no requirement to submit test data or any other forms to support certification. However, manufacturers would be well advised to retain such data as evidence of their due care in certifying compliance with the safety standards. (2) We propose to manufacture an automobile seat frame. Since this is only a component of the actual seat, does the firm who puts together the finished seat apply for approval and testing? As explained previously, neither you nor the firm who puts together the finished seat has to apply for approval and testing. However, your question indicates some confusion regarding the party who is responsible for certifying that the seat complies with federal standards. The answer will vary depending upon the situation in which the seat is installed in a vehicle. Standard No. 207, Seating Systems, is considered a vehicle standard, because it applies only to new vehicles. Therefore, if a seat which incorporates your seat frame is installed in a vehicle during manufacture, the vehicle manufacturer is responsible for certifying that the completed vehicle complies with all applicable standards, including Standard No. 207. If the seat is added to a new, previously certified, motor vehicle prior to its first sale, the person who modifies the vehicle would be an alterer. An alterer is required to certify that, as altered, the vehicle continues to comply with all of the safety standards affected by the alteration. Finally, if the seat is sold as aftermarket equipment to be installed in a used motor vehicle, the seat, as a piece of equipment, does not have to comply with any federal standards. However, 108(a)(2)(A) of the Vehicle Safety Act provides, in pertinent part: No manufacturer, distributor, dealer, or motor vehicle repair business shall knowingly render inoperative, in whole or part, any device or element of design installed on or in a motor vehicle or item of motor vehicle equipment in compliance with an applicable Federal motor vehicle safety standard... Therefore, none of these entities could install a seat containing your seat frame if it caused the vehicle to no longer comply with Standard No. 207 or any other standard. In all of these situations, you, as the manufacturer of the seat frame, have no certification requirements. However, the manufacturer of the seat or the vehicle it is to be installed in will probably require information from you in order to make the necessary certification. I hope you find this information helpful. If you have further questions, please contact Mary Versailles of my staff at this address or by telephone at (202) 366-2992. Sincerely, Paul Jackson Rice Chief Counsel"; |

ID: aiam1494OpenMr. J. B. Dyer, Vice President - Marketing, The Flxible Company, 323 N. Water Street, Loudonville, OH 44842; Mr. J. B. Dyer Vice President - Marketing The Flxible Company 323 N. Water Street Loudonville OH 44842; Dear Mr. Dyer: This responds to your April 23, 1974, questions whether Standard No 121, *Air brake systems; , is a proposal, whether buses manufactured after January 1, 1975, mus conform to Standard No. 121 under all circumstances, what 'cut- off date' exists for determination of brake equipment suppliers' ability to provide 121 components on time, and to what extent a bus must be completed to be certified as in compliance with applicable motor vehicle safety standards.; Standard No. 121 has been a final rule since February 27, 1972, and ha an effective date of January 1, 1973. In 1972 the effective date was postponed until September 1, 1974. Recently the NHTSA further delayed the effective date for trucks and buses until March 1, 1975, having concluded that suppliers will be able to supply all necessary components by that date.; All buses manufactured after the effective date of an applicabl standard must comply with its requirements, under S 108(a)(1) of the National Traffic and Motor Vehicle Safety Act of 1966 (15 U.S.C. S 1392(a)(1)), which states 'No person shall. . .manufacture for sale. . .any motor vehicle. . .on or after the date any applicable Federal motor vehicle safety standard takes effect. . .unless it is in conformity with such standard. . . .'; You asked whether a trailer which is substantially complete before th effective date but lacks one or more parts due to parts shortages can be certified as conforming although it is equipped with a pre-121 brake system. By analogy with the rules allowing manufacturers to omit 'readily attachable' items to be added later in the chain of distribution (Import regulations S 12.80, Parts 567, 568), the NHTSA will accept a good-faith determination that a vehicle is substantially completed, where only a few parts subject to shortages are missing.; I would also like to answer a technical question raised by R. E. House of your engineering staff. In an April 23, 1974, letter he asked for an interpretation of the S5.6.4 language 'The parking brake control shall be separate from the service brake control.' as it applies to the DD-3 two-step brake release. The S5.6.4 requirement for a separate parking brake control is intended to address the actuation of the brake. We interpret this language not to prohibit the use of a two-step release involving a manual and a foot control.; Sincerely, Lawrence R. Schneider, Chief Counsel |

ID: aiam3503OpenMr. Michael M. Packard, Commissioner, Indiana Bureau of Motor Vehicles, State Office Building, Indianapolis, IN 46204; Mr. Michael M. Packard Commissioner Indiana Bureau of Motor Vehicles State Office Building Indianapolis IN 46204; Dear Mr. Packard: This is in response to your letter of November 23, 1981, asking fo suggestions that would enable the citizens of Indiana to do away with the necessity of using and retaining the federal odometer disclosure statement.; In my previous correspondence I indicated that the Indiana Certificat of Title could not be used in lieu of a separate Federal odometer disclosure statement unless additional information was incorporated. In your recent letter you asked whether the title application could be utilized to meet the Federal disclosure requirements. For your information, I have enclosed several notices that have appeared in the *Federal Register* that deal directly with this issue. The first is an August 1977 notice which allows states that wish to utilize their Certificates of Title as disclosure statements to include a shortened odometer disclosure statement, but requires other State documents to contain the longer form. In January 1980 the latter requirement was amended (see enclosed *Federal Register* notice) to allow the shortened form to be used in lieu of a separate Federal disclosure statement on *any* State document which evidences ownership of the vehicle. The effect of this change is to permit the State of Indiana to use the shorter form on its application for title and still have the application satisfy the Federal odometer disclosure requirements.; With respect to your comment that Indiana would like to enable citizen to do away with the necessity of retaining disclosure statements, I am enclosing a copy of a January 1980 *Federal Register* notice which discusses the retention requirements. As you will note, the retention requirements apply only to dealers and distributors (persons who buy or sell five or more motor vehicles within any 12 month period), and not to the average consumer. If Indiana incorporates an acceptable disclosure statement onto its title application, all dealers and distributors will, nevertheless, be required to maintain copies of these documents at their primary place of business. This requirement facilitates enforcement efforts and should not be too great a burden on businesses that already have storage facilities for the other documents.; I hope that I have satisfactorily responded to your concerns. I woul welcome the opportunity to work further with Indiana in the effort to curtail odometer fraud.; Sincerely, Frank Berndt, Chief Counsel |

ID: aiam5087OpenMr. Kevin Mitchell Goodyear Tire & Rubber Co. Sun Prairie, WI 53590; Mr. Kevin Mitchell Goodyear Tire & Rubber Co. Sun Prairie WI 53590; "Dear Mr. Mitchell: This responds to your letter asking about th hydraulic brake hose labeling requirements (S5.2) of FMVSS 106, Brake Hoses. You indicated that your current brake hoses have two stripes, on opposite sides of the hose. Each of the stripes is interrupted by a line of information. One line, which you call the 'DOT print line,' contains the information required by FMVSS 106. The other line, which you call the 'SAE print line,' contains certain information not required by FMVSS 106, including 'batch and shift' information. You asked whether it is permissible to place the batch and shift information (consisting of a mark such as 'AA') on the DOT print line. You stated that moving the batch and shift mark to the DOT print line would improve the legibility of the SAE print line. This is because better print materials could be used in the SAE print line if that legend did not contain a mark that must be updated on a daily or more frequent basis, such as the batch and shift mark. As discussed below, the batch and shift information may not be placed on the same line as the required information. NHTSA's longstanding position, stated in past rulemaking notice preambles (e.g., 39 FR 7425, February 26, 1974, 39 FR 24012, June 28, 1974), is that the DOT print line may only contain the required information. The striping requirement (S5.2.1) of FMVSS 106 states that one of the requisite stripes on a brake hose 'may be interrupted by the information required by S5.2.2, and the other stripe may be interrupted by additional information at the manufacturer's option.' We interpret this to mean that the stripe that is interrupted by the required information may not be interrupted by information voluntarily provided by the manufacturer. This conclusion is consistent with the preamble for the final rule establishing S5.2.1 (38 FR 31302, November 13, 1973), which refers to optional additional information as not being permitted in the legend that interrupts the first stripe. (That rule modified the labeling requirements to permit interruption of the second stripe with the optional information.) NHTSA did not permit optional information to be mixed with the required information because the mixture of optional and required labeling could obscure or confuse the meaning of the required information, or interfere with the appearance of complete labeling on some hose assemblies. For your information, we have enclosed the Federal Register documents cited above. Please contact Ms. Fujita of my staff at (202) 366-2992 if you have any further questions. Sincerely, Paul Jackson Rice Chief Counsel Enclosures"; |

ID: aiam2742OpenMr. John Bonita, Jerome Avenue Dealers Association, 217 Broadway, Bronx, NY 10007; Mr. John Bonita Jerome Avenue Dealers Association 217 Broadway Bronx NY 10007; Dear Mr. Bonita: This is in response to your letter of December 1, 1977, requestin information on the Federal odometer disclosure law.; You asked whether an employee has the authority to sign an odomete disclosure statement relating to the purchase of vehicles sold dealer to dealer. Section 580.4 of Title 49, Code of Federal Regulations, requires each transferor of a motor vehicle to furnish to the transferee a written statement of the mileage traveled by the vehicle. 'Transferor' is defined as 'any person who transfers his ownership in a motor vehicle by sale, gift, or any means other than by creation of a security interest.' In a dealer-to-dealer transaction, as in all other transactions, the owner of the vehicle is responsible for signing the disclosure statement. He may assign that responsibility to an employee or representative. The transferor, however, as the owner of the vehicle, nevertheless remains liable for the actions of his employee.; You also raised the question in your telephone call of January 18, wit Kathy DeMeter of my staff, whether in a wholesale transaction all vehicles could be listed on one invoice as long as separate disclosure statements are issued for each. The National Highway Traffic Safety Administration is concerned with the issuance of correct mileage statements for each vehicle and does not have any objection to all the vehicles being listed in one invoice.; The sample 'Odometer Statement' which you enclosed with your lette meets all of the requirements of the Federal regulation. Thank you for your cooperation in preparing the revised statements.; Sincerely, John Womack, Assistant Chief Counsel |

ID: aiam3850OpenMr. David A. White, Senior Safety Engineer, Grumman Olson, 70180 Centerville Road, Sturgis, Michigan 49091; Mr. David A. White Senior Safety Engineer Grumman Olson 70180 Centerville Road Sturgis Michigan 49091; Dear Mr. White: This responds to your letter of May 3, 1984, asking about Standard No 101, *Controls and Displays*. Your letter concerned requirements applicable to a proposed design for an instrument panel which would include controls for heating fan, windshield wiper and washer, and defrosting system. The controls would be identified both by the symbol specified in Table 1 of Standard No. 101 and the relevant word listing in that table. You asked whether the symbols are required to be illuminated or whether its is permissible instead to illuminate the identifying words without illuminating the symbol. As discussed below, your interpretation of the standard that the symbols must be illuminated is correct.; By way of background information, I would note that the Nationa Highway Traffic Safety Administration does not provide approvals of motor vehicles or motor vehicle equipment. Under the requirements of the National Traffic an Motor Vehicle Safety Act, it is the responsibility of the manufacturer to assure that its vehicles or equipment comply with applicable requirements. The following represents our opinion based on the facts provided in your letter.; Section S5.2.1 of Standard No. 101 generally requires that 'an hand-operated control listed in column 1 of Table 1 that has a symbol designated in column 3 shall be identified by that symbol.' The section states further that '(s)uch a control may, in addition, be identified by the word or abbreviation shown in column 2.' The three controls noted above, heating fan, windshield wiper and washer and defroster system, are all listed in column 1 and have symbols designated in column 3. Thus, the identification required by section S5.2.1 for these controls are the symbols designated in column 3. Use of the words shown in column 2 in addition to the mandatory symbols is permissible but not required.; Section S5.3.1 of Standard No. 101 states: >>>Except for foot-operated controls or hand-operated controls mounte upon the floor, floor console, or steering column, or in the windshield header area, the *identification required by S5.2.1* or S5.2.2 of any control listed in column 1 of Table 1 and accompanied by the word 'yes' in the corresponding space in column 4 shall be capable of being illuminated whenever the headlights are activated. However, control identification for a heating and air conditioning system need not be illuminated if the system does not direct air directly upon windshield...[Emphasis added.]<<<; As discussed above, the identification required by section S5.2.1 fo the three controls are the symbols designated in column 3. Since each of the three controls is accompanied by the word 'yes' in column 4, the required symbols must be capable of being illuminated whenever the headlights are activated It is thus not permissible to illuminate the identifying words without also illuminating the symbols.; I would note that your letter does not provide sufficient informatio to determine whether the controls in you proposed design could come within any of Standard o. 101's exceptions to the illumination requirements.; Sincerely, Frank Berndt, Chief Counsel |

Dietrich Head Traffic Sciences Bolt Beranek and Newman Inc. 50 Moulton Street Cambridge MA 02138; Dear Mr. Dietrich: This is in reply to your letters, both dated December 16, 1970 concerning Motor Vehicle Safety Standard No. 213, 'Child Seating Systems.' One of these letters enclosed a request for clarification of two provisions of Standard No. 213. This request is presently under review and you should be hearing from the agency concerning it in the near future. You also enclosed in this letter a copy of a page from the 1970 Sears, Roebuck & Co. catalogue showing a child harness that is advertised as 'not a safety harness,' and ask whether this type of harness is exempt from the requirements of Motor Vehicle Safety Standard No. 209. The agency considers these types of harnesses to fall within the purview of Standard No. 209 and they are required to comply with the requirements for Type 3 seat belt assemblies as specified in S4. of that standard. Enforcement procedures are currently in progress in this area to eliminate those child harnesses that do not comply with the standard.; Your second letter requests that a study conducted by the University o Michigan Highway Safety Research Institute (Contract No. FH- 11-6962), entitled 'Integrated Seat - Restraint and Child Systems,' be placed in the public docket, and further request that the 'data films of the dynamic sled test be made available through the Docket.' The report to which you apparently refer has been placed in the general reference section of Docket 2-15. It is entitled 'Child Seat and Restraint Systems Test Program' but bears the same contract number as the one you request. With reference to your request for data films, these films are presently available for examination by the public through the agency's Research Institute, and information to this effect has been placed in the Docket.; We are pleased to be of assistance. Sincerely, Lawrence R. Schneider, Acting Chief Counsel |

Alondra Blvd., Gardena, CA 90247; Mr. Brian Gill Assistant Manager Safety & Environmental Activities American Honda Motor Co. Inc. P.O. Box 50 -- 100 W. Alondra Blvd. Gardena CA 90247; Dear Mr. Gill: This is in response to your May 6, 1976, request for confirmation tha the Honda 'MPV' qualifies as a multipurpose passenger vehicle although it is constructed on a 'modified' truck chassis.; In our letter to you of April 30, 1976, we concluded that the Hond 'MPV' would be classified as a multipurpose passenger vehicle, based upon the assumption that the 'MPV' is constructed on a truck chassis. You responded that the 'MPV' is constructed on a 'modified' truck chassis, and questioned whether the National Highway Traffic Safety Administration considered this fact in its previous interpretation.; The reference to 'truck chassis' in the definition of multipurpos passenger vehicle, 49 CFR Part 571.3(b), is intended to include chassis that were designed and developed for trucks, but which have been produced in a version for use in passenger carrying vehicles. According to your letter and drawings of March 1, 1976, the Honda 'MPV' is a passenger version of the Honda TN 500 light truck. Since the modification of the chassis in the production of the 'MPV' does not appear to be so great that the major characteristics of the truck chassis are destroyed, we confirm our previous determination that the Honda 'MPV' qualifies as a multipurpose passenger vehicle.; Sincerely, Stephen P. Wood, Assistant Chief Counsel |

Burgess 1414 Home Savings Building 1006 Grand Avenue Kansas City MO 64106; Dear Mr. Burgess: This is in reply to your request of November 8, 1972, for informatio concerning the effects of governmental regulation on a decorative bumper that your client proposes to manufacture for sale in the automotive 'after-market.'; As far as Federal standards are concerned, your client's product is no a regulated item of equipment as long as it is installed after the vehicle has been sold to a customer for purposes other than resale. Although we have issued a standard to regulate the safety of bumpers on passenger cars (Federal Motor Vehicle Safety Standard No. 215, 49 CFR 571.215, effective September 1, 1972), the standard does not apply to the bumper as a separate item of equipment. Thus, a new car manufactured after the effective date of the standard must conform to the standard, but a bumper manufactured after the effective date and sold separately from the vehicle as a replacement part or add on, does not have to conform.; We strongly recommend, however, that any bumper system developed fo sale in the after-market be designed to conform to the performance requirements of Standard No. 215. If it should happen that significant problems are caused by the sale of inadequate bumpers, it may be necessary to expand the application of the standard to regulate the bumper as a separate item of equipment.; For your added information, state statutes with which we are familia also apply to new vehicles and would presumably not affect the installation of your client's product. However, you might find it advisable to ask the opinion of responsible state officials on this question.; If we can be of further assistance, please let us know. Sincerely, Robert L. Carter, Associate Administrator, Motor Vehicl Programs; |
