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: aiam2320OpenMr. David L. Ryan, Chairman, Topeka Metropolitan Transit Authority, 201 North Kansas Avenue, Topeka, KS 66603; Mr. David L. Ryan Chairman Topeka Metropolitan Transit Authority 201 North Kansas Avenue Topeka KS 66603; Dear Mr. Ryan: This responds to the Topeka Metropolitan Transit Authority's May 17 an 18, 1976, letters asking whether the National Highway Traffic Safety Administration's (NHTSA) definition of school bus or its Standard No. 222, *School Bus Passenger Seating and Crash Protection*, prevent the utilization of transit buses to transport students to and from school. You ask if a proposed amendment to Kansas statutes would conflict with Federal law or regulation if it exempts transit buses from a requirement that school bus seating be forward-facing.; Section 103(d) of the National Traffic and Motor Vehicle Safety Ac (the Act) (15 U.S.C. S 1392(d)) does preempt State motor vehicle safety requirements of general applicability that are not identical to a Federal standard applicable to the same aspect of performance. In this case, the proposed section 10 appears to be identical to S5.1 of Standard No. 222 insofar as it addresses the direction in which school bus seating must face. It is the opinion of the NHTSA that this portion of the proposed section 10 would therefore not be preempted by Standard No. 222.; The second portion of section 10 provides an exception to th requirement for forward-facing seats, and it is the NHTSA's opinion that the exception is preempted insofar as it might apply to school buses purchased by a metropolitan transit authority after the October 26, 1976, effective date of Standard No. 222.; In the case of transit buses 'designed and sold for operation as common carrier in urban transportation,' however, the exception does not apply to an aspect of performance regulated by a motor vehicle safety standard (i.e., the orientation of seating in transit buses). It would therefore not appear to be preempted by any Federal motor vehicle safety standard.; The NHTSA recently considered inclusion of transit buses in th definition of 'school bus' but concluded that Congress' intent in broadening the definition of 'school bus' did not address inclusion of transit buses involved in student transportation. I have enclosed a discussion of this issue that accompanied the redefinition of 'school bus.'; As you noted in your letter, Highway Program Safety Standard No. 17 *Pupil Transportation Safety* (23 CFR 1204), provides for the transportation of students in school buses and in transit buses.; Sincerely, Frank Berndt, Acting Chief Counsel |

Kawano 1099 Wall Street West Lyndhurst NJ 07071; Dear Mr. Kawano: This responds to your January 23, 1978, letter asking whether Safet Standard No. 205, *Glazing Materials*, would be applicable to tempered glass mounted on the outside panel of a vehicle B-pillar' for ornamental purposes.; The answer to your question is no. Since there would be no danger tha vehicle occupants would contact the ornamental glass, it would not have to comply with the performance and location requirements of Standard No. 205. This interpretation assumes, of course, that the glass is used only on the outside panel of a solid B-pillar'. Standard No. 205 would be applicable, for example, if the glass were used in a cut-out section of a B-pillar', such that there was an interface of the glass with the vehicle occupant compartment.; Sincerely, Joseph J. Levin, Jr., Chief Counsel |

ID: aiam3862OpenHonorable Jim Burnett, Chairman, National Transportation Safety Board, Washington, DC 20594; Honorable Jim Burnett Chairman National Transportation Safety Board Washington DC 20594; Dear Mr. Chairman: This is in further response to recommendations H-83-44 and H-83-4 which your agency made to the National Highway Traffic Safety Administration (NHTSA) regarding the Highway Accident Report, 'Jonesboro School District Schoolbus Run-Off-Road and Overturn, State Highway 214 at State Highway 18, near Newport, Arkansas, March 25, 1983' (NTSB/HAR-83/03).; NHTSA agrees with the National Transportation Safety Board tha properly inspected and repaired school buses are essential to the safe transportation of school children. We also believe that the current provisions in Highway Safety Program Standard 1, Periodic Motor Vehicle Inspection, and Highway Safety Program Standard 17, Pupil Transportation Safety, as well as the relevant Federal Motor Vehicle Safety Standards, provide for an adequate level of safety when children are transported to and from school.; Of the 15,840 school districts in the United States, about 15,00 provide pupil transportation. Over 400,000 buses are involved in transporting the nation's 22 million public, private and parochial school children to and from school each day. These buses are maintained by a number of persons having diverse backgrounds ranging in skill from 'grease monkey' to those certified by the national institute for Automotive Service Excellence (ASE). This fleet travels over three billion miles a year, and is remarkably free of problems. Information reported at national meetings indicates that accidents due to mechanical failure are estimated to be between three and five percent and very few result in injury or death.; With respect to the specific recommendations, we have the followin comments:; >>>*RECOMMENDATION H-83-44* (Class II, Priority Action) *Include in Highway Safety Program Standard (HSPS) 17--Pupi Transportation Safety and in the Program Manual' for HSPS 17 the requirement that the States institute quality control procedures for schoolbus repairs to determine if needed repairs have been performed adequately or if major repairs are required.; COMMENT* State Directors of Transportation, school business officials and flee supervisors with whom NHTSA has talked agree that school buses should be kept in good repair. They questioned, however, how quality control procedures could be applied to the repair of school buses when almost every repair is different. Most school buses currently undergo at least two inspections a year, as suggested by Standard 17, which procedure helps to detect major defects that require repair. In addition to this inspection, we understand that most drivers conduct a daily inspection which identifies the need for minor repairs. One supervisor observed that school bus drivers act as a form of practical quality control because they check to determine if the school bus is operating safely after the repair has been made.; A survey of almost 1,000 fleets by the National School Transportatio Association revealed that 49 percent operated fewer than 10 buses. To institute quality control procedures for these small fleets would quickly exhaust the limited resources of most States. Instituting formal quality control procedures would be costly to the States, no matter whether facilities were built and equipment purchased, or alternative checking procedures were utilized.; *Recommendation H-83-45* (Class II, Priority Action) This five part recommendation would include in the Program Manual o Highway Safety Program Standard 17-Pupil Transportation Safety, the program areas listed below.; *1. Specific, well-defined qualifications for hiring schoolbu mechanics,; 2. Specific skill areas for schoolbus mechanics for which certificatio of proficiency is required,; 3. A bibliography of available courses that can be attended or cours curricula that can be used as an example to obtain certification of proficiency in the required skill areas, *Comment*; NHTSA plans to use a portion of staff resources to review th literature that pertains to school bus mechanic qualifications and skill areas needed for certification. Upon completion we will disseminate the appropriate information to State and local governments.; Many schools, colleges and vocational training centers offer variou courses in auto-mechanics, but few people ever master all the major areas of vehicle repair and become master-mechanics. The majority of small fleet operators could not afford to hire such a skilled mechanic. Car dealers employ many skilled mechanics but many are neither equipped nor do they desire to repair school buses. It is highly unlikely that owners of small fleets would or could hire an ASE certified mechanic. It is also unlikely that most of the garages or service stations that maintain school buses have such a person in their employ because they are small independent private entrepreneures (sic). The extreme diversity of the school bus fleet in the United States would be a major complication for a practical certification program.; In 1978, hearings were held by the House Subcommittee on Consume Protection and Finance, of the Committee on Interstate and Foreign Commerce, to examine State and local as well as private sector approaches to the problem of unnecessary, incompetent, or fraudulent repair practices. Senator Philip Hart also held hearings in the late 1960s on Mechanic Training and Licensing. In spite of the adverse findings by these two committees, neither the Federal Government nor any State has gone so far as to require certification of mechanics doing work on cars or school buses. Because of the complexity of this problem, and the lack of Congressional action, NHTSA is of the opinion that it cannot go beyond publishing qualifications for school bus mechanics and identifying available training centers.; States whose accident records show the need for better maintenance car can be expected to take remedial action. Michigan, for example, provided workshops especially designed for school bus mechanics for over 10 years.; *4. A requirement to institute and enforce procedures to prevent schoo activity groups from organizing, beginning, or continuing trips in mechanically unsafe vehicles,; Comment* A requirement to institute and enforce procedures to prevent schoo activity groups from organizing, beginning or continuing trips in mechanically unsafe vehicles is commendable. Such a requirement, however, would be effective only if it were enforced. Standard 17 currently suggests pre-trip inspections and a written report of any defect or deficiency discovered. We believe a reminder to the States of this suggestion would encourage them to give the proper attention to this safety area.; *5. Requirements to place fire extinguishers at the front and rear o school buses, post signs in school buses on the location and use of emergency equipment, and brief passengers on the location and use of emergency equipment, both periodically and before beginning activity trips.; Comment* The placement of additional fire extinguishers outside the bus driver' compartment has led to increased theft and vandalism. These essential pieces of emergency equipment need to remain under the watchful eyes of the bus driver. The benefits of placing a second fire extinguisher in the rear of the school bus are so few as to make this requirement unwarranted. In case of a fire, a bus driver's first responsibility is to get the pupils to a place of safety. Having the personal skill and the equipment to handle a small fire are helpful, but not a necessity.; NHTSA suggests that all pupils who ride school buses should hav instruction twice a year in safe riding procedures and emergency drills. This should provide sufficient information to students concerning the location and use of emergency equipment carried on the school bus. The location and use of fire extinguishers should be a part of this instruction.; Thank you for the opportunity to comment on these safet recommendations. If NHTSA can supply any additional information, please let me know.; |

ID: aiam3531OpenMr. William E. Lawler, Specifications Manager, Indiana Mills & Manufacturing, Inc., 120 West Main Street, Carmel, IN 46032; Mr. William E. Lawler Specifications Manager Indiana Mills & Manufacturing Inc. 120 West Main Street Carmel IN 46032; Dear Mr. Lawler: This responds to your recent letter requesting an interpretatio concerning paragraph S4.3(c)(1) of Safety Standard No. 209, *Seat Belt Assemblies*. You ask for clarification of the cases in which a 5,000-pound attachment bolt may be used in lieu of a 9,000-pound bolt.; Paragraph S4.3(c)(1) of Standard No. 209 specifies that attachmen bolts used to secure the pelvic restraint of a seat belt assembly to a motor vehicle shall withstand a force of 9,000 pounds, except that 'attachment bolts of a seat belt assembly designed for installation in specific models of motor vehicles in which the ends of two or more seat belt assemblies cannot be attached to the vehicle by a single bolt shall have a breaking strength of not less than 5,000 pounds.' The intent of the requirement in S4.3(c)(1) is to assure that inadequate attachment bolts will not be used to attach seat belt assemblies to a vehicle. A 5,000- pound bolt may be used only if the belt assembly is designed for use in specific models of vehicles in which only one end of a belt assembly can be attached by a single bolt.; In answer to your question, the agency does not 'have in mind' certai brands or models of vehicles which would qualify under this exception, and the exception is not limited to single-seat vehicles. Further, the requirement does not mean that a seat belt assembly that can be used in more than one application must be installed with a 9,000-pound bolt. If a particular assembly is designed for use in several different models in all of which only one end of the belt assembly can be attached by a single bolt, then a 5,000- pound bolt is sufficient. The distinction is that an aftermarket belt for universal application must be accompanied with a 9,000- pound bolt, because in some vehicle models it would be possible to mount two ends of seat belt assemblies with a single bolt.; You should note that paragraph S4.1(k) of Standard No. 209 requires th manufacturer of seat belt assemblies for after-market use to furnish an instruction sheet stating whether the assembly is for universal installation or for installation only in specifically stated motor vehicles. If you provide 5,000-pound bolts for any of your assemblies, the instruction sheet required by S4.1(k) should specify that the assemblies are to be used only in the vehicle models you list.; I hope this has answered all your questions. Sincerely, Frank Berndt, Chief Counsel |

Box 4 Leek Wootton Warwick England CV35 8QB; Dear Mr. Birch: This responds to your recent letter concerning a reflective film tha is being applied to the windows of some vehicles in the United Kingdom. You ask whether regulations preventing the use of such film have been introduced in the United States.; At the current time, there are no Federal regulations that prohibit th use of reflective films such as you describe. The National Highway Traffic Safety Administration issues safety standards and regulations governing the manufacture of new motor vehicles and motor vehicle equipment. We have no authority, however, to regulate the use of motor vehicles, such as an owner applying reflective film to his car. Further, we have issued interpretations stating that reflective coated polyester films do not qualify as glazing materials and, therefore, do not come within the purview of our Safety Standard No. 205. This interpretation referred only to polyester film sold by itself. Glazing materials that have coated films that were applied by the glazing manufacturer are required to comply with the standard, including the light transmittance requirements.; The agency did receive a petition for rulemaking last year from th California Highway Patrol asking that reflective glazing materials be prohibited (glazing coated with reflective substances by the glazing manufacturer). While use of the reflective coating could reduce the ability of a driver to look through the glazing of vehicles in front of him or her and see the road and vehicles ahead, we denied the petition since we lacked data indicating that there is a safety problem created by the coating. If you have or know of any data indicating a safety problem, we would very much appreciate seeing the data. From a law enforcement viewpoint, the problem posed by the reflective coating is apparently more than theoretical, since officers cannot see inside a vehicle with coated glazing to the extent they deem necessary.; Sincerely, Frank Berndt, Chief Counsel |

Washington DC 20036; Dear Mr. Hamilton: This is in reply to your letter of August 2 to which you attached letter from Mr. W. Dershko of Motor Coach Industries concerning the certification regulations that go into effect January 1, 1972. (Perhaps by error, you referred to a letter from Mr. Stieber of Greyhound Lines.) Rulemaking concerning gross axle weight rating and gross vehicle weight rating was in process at the time, hence the reason for our delay.; Mr. Dershko asked whether the gross vehicle weight rating must equa the sum of the gross axle weight ratings. The answer is no. The practice described, of stating a GVWR less than the sum of the GAWR's, will be quite proper under the new regulations.; Mr. Dershko also said that he was concerned as to how to interpret th definition of gross axle weight rating, and that 'several factors to consider are the tire capacities, axle assembly capacity, and the coach frame structure capacity.' We agree that all those factors must be considered. The manufacturer must set his gross axle weight ratings in view of the weakest elements in the load-bearing systems of the vehicle.; Let us know if we can be of further assistance. Sincerely, Lawrence R. Schneider, Acting Chief Counsel |

Montvale NJ 07645; Dear Mr. Ziwica: THis is in response to your October 29, 1976, request for confirmatio that a recent NHTSA interpretation regarding the buckle crush requirements of Standard No. 209 (as stated in a letter to Volvo dated August 31, 1976) is applicable to BMW seat belt buckles.; Our letter to Volvo stated that the existing S4.3(d)(3) buckl requirements are not applicable to buckles that are located between bucket seats and attached to the console or to the end of a rigid cable or bar.' This interpretation constitutes an explanation of S4.3(d)(3) as its provisions apply to all seat belt buckles regulated by the standard. The interpretation is not applicable only to Volvo belt buckles or to buckles produced by any other individual manufacturer. It is the responsibility of each manufacturer to determine, in the first instance, whether or not his products fall within any standard's provisions, including provisions that are explained by means of an interpretation.; I am enclosing a copy of our August 31, 1976, letter to Volvo for you information. As requested, we have withdrawn your petition for rulemaking.; Sincerely, Frank A. Berndt, Acting Chief Counsel |

ID: aiam4974OpenRobert S. McLean, Esq. King & Spalding 191 Peachtree Street Atlanta, GA 30303-1763; Robert S. McLean Esq. King & Spalding 191 Peachtree Street Atlanta GA 30303-1763; "Dear Mr. McLean: This responds to your March 9, 1992 letter, seekin an interpretation of Standards No. 208, Occupant Crash Protection and No. 209, Seat Belt Assemblies (49 CFR 571.208 and 571.209, respectively). More specifically, you were interested in how certain provisions of these standards apply to a seating position equipped with an automatic shoulder belt certified as complying with the occupant protection requirements of Standard No. 208 and a separate manual lap belt. Your letter indicated you were particularly interested in whether the automatic belt is considered a Type 2a shoulder belt, as that term is defined in S3 of Standard No. 209, and whether the automatic belt must provide the warning instructions required for Type 2a shoulder belts by S4.1(l) of Standard No. 209. The answer to both these questions is no. NHTSA has consistently recognized a distinction between automatic safety belts and the manual safety belts defined in S3 of Standard No. 209 (Type 1, Type 2, and Type 2a belts). The origins and application of this distinction is explained at length in this agency's April 14, 1986 interpretation letter to Mr. David Martin, a copy of which was enclosed in your letter to me. Thus, automatic belts are not treated as Type 1, Type 2, or Type 2a belts for the purposes of Standard No. 209, and are not generally subject to the provisions of Standard No. 209 that apply to each of those types of belts. Since automatic belts are not Type 2a belts, automatic belts are not required to include any warnings required for Type 2a belts. Instead, S4.5.3 of Standard No. 208 defines the term 'automatic belt' and sets forth special provisions for such safety belts. S4.5.3.3 specifies that an automatic belt shall conform to S7.1 of Standard No. 208 (the belt adjustment requirements) and have a single emergency release mechanism, and be equipped with a special warning system in place of the warning system required for manual belts. In addition, S4.5.3.4 specifies that any automatic belts that are not subject to the crash testing requirements for occupant protection under Standard No. 208 must comply with the requirements of S4.2, S4.3, and S4.4 of Standard No. 209 (webbing, attachment hardware, and belt assembly performance requirements, respectively). I hope this information is helpful. If you have any further questions or need some additional information on the requirements applicable to automatic belts, feel free to contact Steve Kratzke of my staff at this address or by telephone at (202) 366-2992. Sincerely, Paul Jackson Rice Chief Counsel"; |

ID: aiam0034OpenHonorable Bob Wilson, House of Representatives, Washington, DC, 20515; Honorable Bob Wilson House of Representatives Washington DC 20515; Dear Mr. Wilson: This is in response to your letter of August 16 in which you attached letter from your constituent, Mrs. Beverly Hoffman of San Diego. Mrs. Hoffman asked if there is any Federal or state regulation, or city ordinance, which forbids the removal or concealment of passenger seat belts in taxicabs. Mrs. Hoffman has raised an important question and one which is of vital concern to the objectives of the National Traffic and Motor Vehicle Safety Act of 1966: the retention of a (sic) safety equipment in a vehicle after its original purchase.; Since I expect that California law is of most interest to both Mrs Hoffman and you, I will answer her question on the basis of the California Vehicle Code. Since January 1, 1964, Section 27309 has made it an offense to sell in California any new passenger vehicle which does not have at least two state approved restraint belts or harnesses in its front seat. Retention of the front seat belts by the vehicle owner is indirectly required by Section 40001(b)(2) which makes it unlawful for 'an owner to request, cause, or permit the operation of any vehicle which is not *equipped as required in this Code*.' (emphasis supplied) Since California has no annual motor vehicle inspection, enforcement of this law has presumably been by spot inspection. Members of the California Highway Patrol (Section 2804) and city traffic officers (Section 2806) have the authority to inspect a vehicle to determine whether its equipment is in compliance with the Code.; With respect to rear seat belts which most directly concern Mrs Hoffman as a passenger, their installation has not been required by the Code. Such belts as she may have seen in the rear of California taxis have been provided as a courtesy of the owner rather than as a requirement of the law. But, as she correctly notes, all passenger cars including taxicabs manufactured on or after January 1, 1968, must comply with Federal motor vehicle safety standards. One of these, Standard No. 208, will require taxis to be manufactured with lap restraint belts installed in each rear seating position. But if the California legislature has not amended the Vehicle Code itself to require their installation it would appear that there is no legal reason why a cab owner may not remove rear seat belts should he wish to go to the trouble.; Under the Act, the Secretary of Transportation does not have th authority to directly regulate motor vehicles 'after the first purchase of it in good faith for purposes other than resale.' Instead, Congress intended that used vehicles be regulated by periodic state inspection. To implement this intent the Secretary has been directed to study state inspection systems and, in due course, to establish uniform standards applicable to all used motor vehicles. A hypothetical standard--and one which we shall consider--requiring the presence of original equipment safety items at time of each inspection would be sufficient to cover retention of rear seat safety belts. But the Act establishes no requirement that the states or any individual follow any used vehicle standard. For the probably enforcement mechanism of used car standards it is necessary to turn to the companion Highway Safety Act of 1966. Under this Act each state is required to have a highway safety program in accordance with standards promulgated by the Secretary. One such standard, already issued, establishes minimum requirements for periodic motor vehicle inspection. Eventually it is possible that used car standards will be suggested to the states through this motor vehicle inspection standard, but enforcement of the used car standards will be left to the states.; Concerning concealment of the belts, I am aware of no legislation Federal, state, or municipal, which requires that a safety item not only be retained but also available for use. But I believe that sufficient authority may exist in the Highway Safety Act's mandate to the Bureau to include 'vehicle operation' in the highway safety program standards to warrant our serious consideration of it.; I hope that this has answered Mrs. Hoffman's questions and I appreciat her interest in traffic safety.; Sincerely, William Haddon, Jr., M. D., Director |
