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: nht91-2.43OpenDATE: March 22, 1991 FROM: H. George Johannessen, P.E. -- Chairman, Automotive Occupant Restraints Council (AORC) Seat Belt Technical Committee TO: Paul Jackson Rice -- Chief Counsel, NHTSA COPYEE: Barry Felrice -- NHTSA Associate Administrator for Rulemaking; Dan Cohen -- NHTSA Office of Vehicle Safety Standards; Clarke Harper -- NHTSA Office of Vehicle Safety Standards; S.R. Kratzke -- NHTSA Office of Chief Counsel; Alfred J. Fisher, III -- Chairman, AORC Board of Directors; Charles H. Pulley -- President, AORC; Donald P. Reed -- Reed Technical Relations TITLE: Subject: Request for Interpretation; Re: Federal Motor Vehicle Safety Standard No. 209; Seat Belt Assemblies - S4.1(b) ATTACHMT: Attached to letter dated 8-8-91 from Paul Jackson Rice to H. George Johannessen, P.E. (A38; Std. 208; Std. 209; Std. 210) TEXT: The primary purpose of the Automotive Occupant Restraints Council (formerly the American Seat Belt Council, organized in 1961) is to reduce highway traffic accident fatalities and injuries by providing the motoring public with the most reliable and effective occupant crash protection systems; and beyond this, by conducting a continuous education program, to promote public acceptance and use of such systems. The membership of the AORC represents 90% of the total domestic seat belt industry and domestic inflatable restraints industry. Member companies of AORC supply seat belt assemblies produced in compliance with applicable requirements of FMVSS No. 209; Seat Belt Assemblies. A portion of Paragraph S4.1 (b) of FMVSS 209 states that ". . . the pelvic restraint shall be designed to remain on the pelvis under all conditions, including collision or roll-over of a motor vehicle." The cited statement first appeared in SAE Standard J4c developed by the SAE Seat Belt Committee and issued in 1965. This SAE standard served as the basis for seat belt standards issued subsequently by the Department of Commerce (National Bureau of Standards) in 15 CFR 9 in 1966 and FMVSS No. 209, issued by the National Highway Safety Bureau in 1967. The SAE Committee included the cited statement as a design goal to alert seat belt designers to give full consideration to this aspect of performance. The committee members were aware that they had no objective test procedure to confirm compliance with this design goal. Also, they were aware that the seat belt would not necessarily remain on the pelvis during the entire collision event in all of the varied collisions encountered in the field. The writer was an active member of the cognizant SAE committee and agreed with the committee's decision to include the cited statement as a design goal despite the lack of an objective test protocol to confirm compliance and the recognition that the design goal would not be realized in some collision events. Furthermore, the committee members were aware that there could be no guarantee that the goal would not be thwarted by the vehicle occupant by non-use or misuse of the seat belt or by abnormal position of the belted occupant. Unfortunately, positioning of the seat belt off the pelvis, for whatever reason, has been cited in recent litigation as prima facie evidence that the seat belt does not comply with the federal standard and the seat belt design is defective. The need to refute the allegations of design defect and non-compliance with applicable standards leads to unnecessary expenditure of time and effort and unconscionable societal costs. The AORC requests the NHTSA to provide an interpretation that recognizes that off-pelvis location of a Type 1 lap belt or the lap belt portion of a Type 2 seat belt assembly before, during or after a real world collision does not per se constitute noncompliance of the seat belt with the federal standard nor does this render the seat belt design defective. Such a formal interpretation is necessary to mitigate unnecessary costs in litigation and the resultant societal costs. The AORC considers that time is of the essence and requests NHTSA to act as quickly as possible on this request. Personnel from the AORC staff or member companies will be pleased to provide any additional available information that the agency may need. |

ID: nht91-2.44OpenDATE: March 25, 1991 FROM: Paul Jackson Rice -- Chief Counsel, NHTSA TO: Nancy J. Hunt -- Bankston & McDowell TITLE: None ATTACHMT: Attached to letter dated 1-24-91 from Nancy J. Hunt to Paul Jackson Rice TEXT: This responds to your letter requesting information about test conditions in Federal motor vehicle safety standard No. 301, Fuel system integrity (49 CFR 571.301; copy enclosed). In particular, you asked whether the spare tire must be in its proper place inside a vehicle at the time of testing. You also asked whether the spare tire must be in the vehicle during other types of vehicle testing. I am pleased to have this opportunity to explain our laws and regulations for you. Before addressing your specific question, it might be helpful to begin with some general background information. Each of this agency's safety standards specifies 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. In addition to the test conditions and procedures set forth in the safety standards themselves, the agency has provided guidelines to the test facilities that the agency enters into contracts with to conduct compliance tests for the agency. These guidelines are called compliance test procedures and are available through the NHTSA Technical Reference Library. The compliance test procedures are intended to provide a standardized testing and data recording format among the various contractors that perform testing on behalf of the agency, so that the test results will reflect the performance characteristics of the product being tested, not differences between the various testing facilities. The compliance test procedures must, of course, not be inconsistent with the procedures and conditions that are set forth in the relevant safety standard. However, the compliance test procedures do, on occasion, specify procedures and conditions that go beyond what is set forth in the relevant standard. These more detailed test procedures and conditions are requirements only for the contractor test facility in conducting tests on behalf of the agency. The test procedures are subject to change and do not always directly reflect all of the requirements of the particular standard for which they are written. With that background, I will now address your specific question. A manufacturer must certify that its vehicles will comply with the requirements of Standard No. 301 when they are tested in accordance with the test conditions set forth in section S7 of the standard. This section specifies the general test conditions under Standard No. 301. However, this section does not specify whether a spare tire must be included during the testing. Accordingly, the manufacturer's certification of compliance with Standard No. 301 may be based on tests with or without the spare tire, provided that all applicable conditions in Standard No. 301 are satisfied. You should be aware that NHTSA's compliance test procedures currently specify that if the spare tire is standard equipment, it should be inflated to the vehicle manufacturer's specifications and be in the vehicle during the agency's compliance testing (see page 27 of the "OVSC Laboratory Test Procedures," copy enclosed). Please note that, although a manufacturer is not required to include a spare tire that is standard equipment, absence of a spare tire might not provide an adequate basis for certifying that the tested vehicle complies with the requirements of Standard No. 301. I hope this information is helpful. If you have any further questions, you should feel free to contact Marvin Shaw of my staff at this address or by telephone at (202) 366-2992. |

ID: nht91-2.45OpenDATE: March 25, 1991 FROM: Paul Jackson Rice -- Chief Counsel, NHTSA TO: Saburo Inui -- Corporate Manager, Toyota Motor Corporate Services of North America, Inc. TITLE: None ATTACHMT: Attached to letter dated 2-20-91 from Saburo Inui to Paul Jackson Rice TEXT: This responds to your letter of February 20, 1991, with respect to an interpretation of Standard No. 108 as it relates to High Intensity Discharge Headlamp (HID) designs contemplated by Toyota. You explained these designs in greater detail to NHTSA staff members in a meeting with them on February 20. Standard No. 108 defines an "integral beam headlamp" as one which is neither a sealed beam headlamp nor one equipped with a standardized replaceable light source, but one which is a "headlamp comprising an integral and indivisible optical assembly, including lens, reflector, and light source." You have presented two HID headlamp designs, and have asked whether these lamps are "integral beam headlamps" as defined by Standard No. 108. These lamps differ from conventional headlamps by having ballast, consisting of a "starter" affixed to the rear of the headlamp, connected to a "converter," which is separated from the headlamp-starter unit. Because of space limitations, it may not be feasible to integrate the ballast into the headlamp enclosure. On one of these headlamps (Figure 2) the starter and converter are directly connected to each other by a "hard wire" while in the other (Figure 3), the starter and converter are connected by "hard wires" that meet at a connector between the two. In this design, the ballast units would be installed separately, then permanently joined by a connector, which could not be separated without destroying the connector. You believe that both designs are "integral beam headlamps." The phrase "optical assembly" in the definition of "integral beam headlamp", in our view, encompasses all lamp components other than the power source which are required for illumination of the headlamp. This means that an "optical assembly includes the ballast. Although the lamp, starter, and converter may be permanently attached to each other, and could be considered "indivisible," and the starter could be considered to be "integral" with the lamp body, the positioning of the converter at some distance from the starter, as shown in your Figure 2 and Figure 3, does not render it "integral" within the meaning of the definition, unless it is permanently attached to the starter. However, a design which had a connector as in your Figure 3 and described in your letter, would be considered both "integral" and "indivisible" if its individual components were not permanently attached to each other until the installation of the device in a motor vehicle, providing that any portion of the device could not be subsequently detached without damage sufficient that the entire device would have to be replaced. This would apply to either original or replacement equipment. |

ID: nht91-2.46OpenDATE: March 25, 1991 FROM: Paul Jackson Rice -- Chief Counsel, NHTSA TO: Charles A. Schue, Jr. TITLE: None ATTACHMT: Attached to letter dated 2-27-91 from Charles A. Schue, Jr. to DOT/NHTSA Director, Office of Vehicle Safety Compliance (OCC 5782) TEXT: This responds to your letter of February 27, 1991, to the Director, Office of Vehicle Safety Compliance, with respect to your prospective importation of a 1979 Mercedes-Benz 300D. You have requested a "waiver of purchase date requirement" as outlined in the DOT "Guide for Complying with Regulations on Imported Motor Vehicles", and, if this cannot be granted, information of "other provisions under which I may request approval to import this vehicle into the U.S.A." We are happy to provide you with an interpretation of the importation regulations (49 CFR Part 591). One of its provisions will apply to your situation. A vehicle is admitted after its importer has executed a Form HS-7 at the port of entry. As one of its provisions will apply to you, there is no need to obtain written approval in advance from us. First, there is no restriction upon importation if the vehicle, in fact, complies with the Federal motor vehicle safety standards. You report that the Mercedes has had two previous American owners in Turkey. If the car was originally bought by an American, even though in Turkey, there is the possibility that the vehicle was originally manufactured to conform to the Federal motor vehicle safety standards. Conformance with the standards at time of manufacture may be verified by the manufacturer's label certifying compliance, usually placed in the driver's door post area. If your Mercedes has such a label, then it may be imported without the necessity of demonstrating conformance. An importer who is a nonresident of the United States may import a nonconforming vehicle temporarily without the necessity of conforming it to the standards. The fact that you have been employed in Turkey since June 1986 raises the possibility that you may not intend a permanent importation of the Mercedes. If you intend to seek employment again outside the United States, and if the Mercedes will be in the United States for less than a year, you would appear eligible to import the car under the nonresident provisions. However, if you intend permanent importation and if your Mercedes lacks the certification label, the car is subject to the importation provisions affecting nonconforming vehicles. You have asked about your eligibility to import a vehicle under the provisions set forth in the Guide. The "purchase date" provision to which you refer is 49 CFR 591.5(g)(3). This requirement was mandated by 15 U.S.C. 1397(g)(3). Subsection (g) contains conditions, all of which must be fulfilled in order to import nonconforming vehicles under the more liberal provisions that were in effect before January 31, 1990. One of these conditions, as set forth in section 1397(g)(3), is that the importer "had acquired (or had entered into a binding contract to acquire) (the motor) vehicle before the date of enactment of this subsection (October 31, 1988)." In establishing this requirement, Congress provided no authority to exempt anyone from its terms. Thus, unless you had a binding contract as of October 31, 1988, to acquire the Mercedes that you purchased on May 15, 1989, you are not eligible to import the vehicle under section 591.5(g). The requirements under which you may be eligible to permanently import your Mercedes are set forth in section 591.5(f). Unfortunately, these are not explained in the DOT Guide that you have. For your information, I enclose a current copy of 49 CFR Part 591. In brief, two events must occur before you may import your noncomplying vehicle into the United States pursuant to this section. First, this agency must have made a determination that the vehicle is capable of being converted to comply with the Federal motor vehicle safety standards. Second, after such a determination, the vehicle may be imported only by a "registered importer" (essentially an entity that the agency has recognized as capable of converting the vehicle to comply with the standards), or by the vehicle owner who has a contractual relationship with a registered importer to perform conversion work. You will be pleased to know that the agency has already determined that noncomplying 1979 Mercedes-Benz 300D passenger cars are eligible for importation. I enclose a copy of our Final Determination on this and other cars that was published in the Federal Register on November 13, 1990. The agency's Office of Vehicle Safety Compliance can furnish you a list of registered importers, and I suggest that you contact them shortly before you intend to import the car, so that the list will be current. Attachments Copy of Federal Register, Vol. 55, No. 219, 11-30-90; Final Determinations That Certain Nonconforming Vehicles Are Eligible For Importation. (Text omitted) Copy of 49 CFR Part 591, Importation of Vehicles & Equipment Subject To Federal Safety, Bumper & Theft Protection Standards (Text omitted) |

ID: nht91-2.49OpenDATE: March 26, 1991 FROM: Paul Jackson Rice -- Chief Counsel, NHTSA TO: Jessie M. Flautt TITLE: None ATTACHMT: Attached to letter from Jessie M. Flautt to Steven Kratzske (OCC 5813) TEXT: This responds to your letter to Mr. Steve Kratzke of my staff, requesting that the National Highway Traffic Safety Administration (NHTSA) grant permission to a repair business to modify your motor vehicle. You explained that you are under five feet, two inches and legally blind in one eye. You further explained that, due to the increased size of headrests in recent years, you are unable to locate a 1991 automobile which does not have headrests which impede your field of vision. You wish to arrange to have the size of the headrests in a 1991 automobile reduced. You asked if you could obtain permission from this agency to permit this modification. I hope the following discussion explaining our regulation will be of assistance to you. I would like to begin by clarifying that there is no procedure by which persons petition for and are granted permission from NHTSA to arrange to have a motor vehicle repair business modify their motor vehicle. Repair businesses are permitted to modify vehicles without obtaining permission from NHTSA to do so, but are subject to certain regulatory limits on the type of modifications they may make. In certain limited situations, we have exercised our discretion in enforcing our regulations to provide some allowances to a repair business which cannot conform to our regulations when making modifications to accommodate the special needs of persons with disabilities. Since your situation is among those given special consideration by NHTSA, this letter should provide you with the relief you seek. Our agency is authorized to issue Federal Motor Vehicle Safety Standards (FMVSS) that set performance requirements for new motor vehicles and items of motor vehicle equipment. Manufacturers are required by the National Traffic and Motor Vehicle Safety Act (Safety Act) to certify that their products conform to our safety standards before they can be offered for sale. Manufacturers, distributors, dealers and repair businesses modifying certified vehicles are affected by S108(a)(2)(A) of the Safety Act. It prohibits those businesses from knowingly rendering inoperative any elements of design installed on a vehicle in compliance with a FMVSS. In general, S108(a)(2)(A) would require repair businesses which modify motor vehicles to ensure that they do not remove, disconnect or degrade the performance of safety equipment installed in compliance with an applicable safety standard. Violations of S108(a)(2)(A) are punishable by civil fines up to $1,000 per violation. In situations such as yours where a vehicle must be modified to accommodate the needs of a particular disability, we have been willing to consider any violation of S108(a)(2)(A) a purely technical one justified by public need. I can assure you that NHTSA would not institute enforcement proceedings against a repair business that modifies the headrest on your vehicle to accommodate your condition. We caution, however, that only necessary modifications should be made to the headrest to accommodate your condition and we urge your dealer to modify your vehicle in such a manner that would not degrade from the safety currently provided by your vehicle. Many manufacturers are currently installing headrests in vehicles which exceed the minimum dimensions required by FMVSS No. 202, Head Restraints. I urge you not to have your headrest reduced below these dimensions if it is not necessary for your field of view. If you have further questions or need some additional information in this area, please contact Mary Versailles of my staff at this address or by telephone at (202) 366-2992. |

ID: nht91-2.5OpenDATE: February 28, 1991 FROM: Z. Taylor Vinson -- Senior Staff Attorney, NHTSA TO: Files: Interps. Std. 108; Redbook (3) TITLE: Re Interpretation Letter to Oshkosh TEXT: On February 14, 1991, John Calow, Senior Safety Engineer, Oshkosh Truck Corp. (414-255-9151 ext. 2038) telephoned me about the agency's letter of January 16, 1991, with respect to override of the stop signal by the turn signal. Our letter assumed that turn signals and hazard warning signals (which operate through the turn signal lamps) have a common circuit, and implied that the hazard signals must also override the stop signals when stop signals are optically combined with turn signals. Mr. Calow asked whether the override would be required if the hazard signal were on a separate circuit. I informed him that the override would not be required because the SAE requirement relates only to turn signal lamps. |

ID: nht91-2.51OpenDATE: March 27, 1991 FROM: Paul Jackson Rice -- Chief Counsel, NHTSA TO: Earl C. Lempke -- President, Delavan Industries, Inc. TITLE: None ATTACHMT: Attached to letter dated 3-6-91 from Earl C. Lempke to Taylor Vinson (OCC 5720) TEXT: This responds to your letter of March 6, 1991, to Taylor Vinson of this office. You have asked whether there is "any Federal ruling stating that Trailer Clearance Lights are considered as Safety Equipment and as such are not be be included as part of the overall width of the vehicle." You have enclosed a copy of 49 CFR 323.20, the clearance lamp regulation of the Federal Highway Administration (FHWA), with the observation that this section does not answer the question. I am pleased to clarify this situation for you. As the FHWA regulation states, "Clearance lamps shall be mounted so as to indicate the extreme width of the motor vehicle . . . ." This requirement is virtually identical to that in Table II of this agency's Federal Motor Vehicle Safety Standard No. 108 that clearance lamps be located "to indicate the overall width of the vehicle . . . ." In 1976, NHTSA issued an interpretation that was published in the Federal Register on August 23 of that year stating that "The term 'overall width' refers to the nominal design dimension of the widest part of the vehicle, exclusive of . . . marker lamps" such as clearance lamps. I enclose a copy for your information. The FHWA concurs with this interpretation, and has provided us with some additional comments. Federal width limits apply only on the National Network highways (23 CFR 658, Section A). The width of commercial trailers operated on these highways is to be measured across the sidemost load carrying structures, support members, and structural fasteners, as stated in an interpretation published on March 13, 1987, a copy of which I enclose. That proceeding also determined that side marker lamps and any other "non load-carrying safety appurtenance" which extended beyond these limits were excluded from width measurements. This would include clearance lamps, and thus exclude them also from width measurements. In December 1989, FHWA issued an advance notice of proposed rulemaking to consider if a new approach should be adopted to determine which devices to exclude from measurements of vehicle length and width. I also enclose a copy of that notice. FHWA advises that its next notice on the subject should be issued soon. Although under FHWA regulations, the States determine whether safety equipment is to be excluded from the measurement of vehicle width, we believe that the State determination must be identical to the NHTSA position. Federal law (15 U.S.C. 1392(d)) prohibits a State from enacting or maintaining in effect any regulation covering the same aspect of performance as a Federal motor vehicle safety standard unless it is identical to the Federal requirement. We believe that a State must also interpret an identical regulation in a manner identical to NHTSA's interpretation. Attachment Copy of a portion of the Federal Register dated 8-23-76 regarding "overall width". (Text omitted) Copy of FHWA interpretation dated 3-13-87, regarding 23 CFR Part 658, truck length and width exclusive devices. (Text and graphics omitted) |
