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: 1989yOpen Mr. Bradley J. Baker Dear Mr. Baker: This is in reply to your letter to Taylor Vinson of this Office, with reference to a product your company manufactures, a "car dolly used to tow a vehicle behind motor homes." You question whether the dolly is a motor vehicle, and if so, whether identification lamps are necessary for it. I regret the delay in responding. The car dolly appears to be a vehicle drawn by mechanical power manufactured primarily for use on the public roads, and thus a "motor vehicle" subject to the jurisdiction of this agency. Specifically, it would be a "trailer", since it is a motor vehicle without motive power, designed for carrying property and for being drawn by another motor vehicle. Federal Motor Vehicle Safety Standard No. l08, Lamps, Reflective Devices, and Associated Equipment, requires identification lamps on all trailers whose overall width is 80 inches or more. Therefore, if the overall width of your dolly is less than 80 inches, it need not be equipped with identification lamps. Sincerely,
Stephen P. Wood Acting Chief Counsel / Ref:l08 d:8/3l/89 |

ID: 1990yOpen Thomas A. Coz, Esq. Dear Mr. Coz: This is in reply to your letter of April 28, l989, with respect to the legality under Standard No. l08 of supplemental lighting devices that North American Van Lines has installed on some of its trailers. To assist us in answering your question, you have enclosed a photograph of a trailer retrofitted with the supplemental devices, and a videocassette. However, the "Final Specs" sheets referenced in your letter were not enclosed. The lamps in question are stop lamps/turn signal lamps which are mounted above the maximum mounting heights specified in Standard No. l08. You believe that this is permissible because they are supplemental to the original equipment stop and turn signal lamps which are mounted within the limits specified in the standard. However, the Department of California Highway Patrol has informed you that this agency does not differentiate between original and supplemental equipment, and requires that both original and supplemental lighting equipment must conform to the mounting requirements. We are not aware of the basis of the California opinion. The only requirement of Standard No. l08 for supplemental lighting equipment on vehicles prior to their first purchase for purposes other than resale is the restraint of paragraph S5.l.3 that they not impair the effectiveness of the lighting equipment required by the standard. Retrofit by North American Van Lines itself of its own vehicles after the first purchase for purposes other than resale is permissible under Federal law. However, if the retrofit were performed by a manufacturer, dealer, distributor, or motor vehicle repair business, the operation would be subject to the restraint of Section 108(a)(2)(A) of the National Traffic and Motor Vehicle Safety Act (l5 U.S.C. 1397(a)(2)(A)) that it not render inoperative, in whole or in part, lighting equipment installed in accordance with Standard No. l08. Subject to these constraints, a mounting height that exceeds the maximum specified by Standard No. l08 is permissible for supplemental lighting equipment. We interpret "partially inoperative" as also meaning "partially ineffective". The location of your lamps as shown in the photograph you enclosed does not appear to "render inoperative" any other lighting device or affect its effectiveness. We note that the retrofitted trailer in the videocassette does not appear to be equipped with the identification lamps required by Standard No. l08. Further, unless the clearance lamps are combined with the supplemental stop/turn signals in both the videocassette and the photograph you enclosed, they too appear to be missing. If the clearance lamps are combined with the supplementary lamps, care should be taken that the supplementary lamps do not "render inoperative" the clearance lamps. Although, as noted above, the Act permits an owner to modify his vehicle in a nonconforming manner, the operation of your interstate highway trailer is subject to the regulations of the Bureau of Motor Carrier Safety, Federal Highway Administration, which require that identification and clearance lamps be provided for these trailers. We are returning your videocassette. Sincerely,

ID: 19914.drnOpenMatt Boley, Executive Director Dear Mr. Boley: This responds to your request for information regarding transportation of school children from school to your facility and during the school day. You write that, in addition to providing services for school children, you offer adult programs such as English as a Second Language and Citizenship classes, as well as senior citizen and health outreach programs. In a telephone conversation with Dorothy Nakama of my staff, you stated that you regularly provide transportation from school for the school children and that you are using 15-person vans to transport both the adults in your program and the children. Some background information would be helpful in answering your question. The National Highway Traffic Safety Administration ( NHTSA) is authorized to issue and enforce Federal motor vehicle safety standards applicable to new motor vehicles. Our statute at 49 U.S.C. 30112 requires any person selling or leasing a new vehicle to sell or lease a vehicle that meets all applicable standards. Accordingly, persons selling or leasing a new "school bus" must sell or lease a vehicle that meets the safety standards applicable to school buses. Our statute defines a "schoolbus" as any vehicle that is designed for carrying a driver and more than 10 passengers and which, NHTSA decides, is likely to be "used significantly" to transport "preprimary, primary, and secondary" students to or from school or related events. 49 U.S.C. 30125. By regulation, the capacity threshold for school buses corresponds to that of buses -- vehicles designed for carrying more than ten (10) persons. For example, a 15-person van that is likely to be used significantly to transport students is a "school bus." In recent interpretation letters to NHTSA, the agency was asked to address situations where non-educational institutions (such as day care centers) are procuring buses to transport children to or from schools. When a day care center will be using a bus to transport school children "to or from school" or school-related activities on a regular (non-occasional) basis, the dealer who sells or leases the new bus to the center must sell or lease a "school bus." These may include van-based vehicles, completed by school bus manufacturers, that are certified to those standards. In contrast, if a day care center will not use the new bus to take children to or from school or school-related activities, the dealer is not required to sell or lease a school bus. One of those letters involved a dealer selling a new 15-passenger van to a child care facility which planned to significantly use the van for school transportation. The letter is dated July 23, 1998, to Mr. Don Cote of Northside Ford in San Antonio, Texas (copy enclosed). In that letter, we explained that a dealer selling or leasing a new van for such use must sell or lease only buses that meet Federal motor vehicle safety standards for school buses, even when the purchaser is a child care facility.(1) Because our regulations apply only to the manufacture and sale of new motor vehicles, we do not prohibit centers from using their large vans to transport school children even when the vehicles do not meet Federal school bus safety standards. However, each State has the authority to set its own standards regarding the use of motor vehicles, including school buses, so you should also check Iowa law to see if there are regulations about how your center must transport school children. Further, we wish to emphasize that school buses are one of the safest forms of transportation in this country, and that we therefore strongly recommend that all buses that are used to transport school children be certified as meeting NHTSA's school bus safety standards. In addition, using 15-person vans that do not meet NHTSA's school bus standards to transport students could result in increased liability in the event of a crash. Since such liability would be determined by State law, you may wish to consult with your attorney and insurance carrier for advice on this issue. I hope this information is helpful. For more information about the safety features of a school bus, I am enclosing NHTSA's publication: "School Bus Safety: Safe Passage for America's Children." I am also enclosing NHTSA's February 1999 "Guideline for the Safe Transportation of Pre-school Age Children in School Buses." If you have any further questions please feel free to contact Dorothy Nakama of my staff at this address or by telephone at (202) 366-2992. Sincerely, 1. Again, please note that NHTSA has never stated that day care facilities that provide only custodial care are "schools." NHTSA's laws do not affect new bus sales to child care facilities that are not significantly involved in transporting school aged children "to or from" school. The Cote letter could affect the facility if it is involved in transporting children to or from school. |

ID: 1991yOpen Mr. Terry Hudyma Dear Mr. Hudyma: Thank you for your letter requesting an interpretation of 49 CFR Part 567, Certification. Specifically, you asked about certification requirements for multipurpose passenger vehicles that will be assembled in Italy and in Michigan. I apologize for the delay in this response. The vehicles in question will be assembled in Italy to the extent that they will be "complete with everything except the engine (and associated equipment such as ignition and air conditioning, etc.), transmission and transfer case in Italy." These assemblies will then be imported into the United States where the vehicles will be completed. You state that both the operations in Italy and in Michigan will be performed pursuant to a contract with LAFORZA, who will have "complete control over the manufacturing process at all times." It is your understanding that in the fact situation described above, LAFORZA is considered to be the manufacturer of the vehicle and therefore LAFORZA is responsible for affixing the certification label on the completed motor vehicle pursuant to 49 CFR Part 567. You asked us to confirm this interpretation. We cannot do so. Under our law and regulations, the company that completes the vehicles in Michigan is a "manufacturer" of the vehicles in question. The information provided in your letter is inadequate to allow us to determine whether LAFORZA might also be considered a "manufacturer" of these vehicles. The first issue to be addressed in our analysis is whether the products in question are "incomplete vehicles" when they arrive in the United States. An "incomplete vehicle" is defined at 49 CFR 568.3 as: ... an assemblage consisting, as a minimum, of frame and chassis structure, power train, steering system, suspension system, and braking system, to the extent that those systems are to be part of the completed vehicle, that requires further manufacturing operations, other than the addition of readily attachable components, such as mirrors or tire and rim assemblies, or minor finishing operations such as painting, to become a completed vehicle. Your letter states that the products that arrive in the United States will not have an engine or transmission, which means they will not have a power train. Accordingly, 568.3 makes clear that these products would not be "incomplete vehicles" for the purposes of our regulations. In previous interpretations, we have referred to products that do not qualify as "incomplete vehicles" as an "assemblage of items of motor vehicle equipment". In those previous letters, we have stated that the assemblage should be labeled as items of motor vehicle equipment for importation into the United States and that the importer of the assemblage must certify that each item of motor vehicle equipment that is covered by a Federal motor vehicle safety standard complies with such standard. See the enclosed May 6, 1985 letter to Mr. Hayley Alexander. This finding also means that the Italian company that produces these "assemblages of items of motor vehicle equipment" is not a "manufacturer" of motor vehicles with respect to the vehicles in question. Section 102(5) of the National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1391(5); the Safety Act) defines a "manufacturer" as "any person engaged in the manufacturing or assembling of motor vehicles or motor vehicle equipment, including any person importing motor vehicles or motor vehicle equipment for resale." In this case, the Italian company producing the assemblage of items of motor vehicle equipment has not manufactured or assembled any motor vehicles, nor has it imported any motor vehicles. Hence, it does not fit the statutory definition of a "manufacturer" of the vehicles in question. After these assemblages are imported into the United States, the operations performed by the Michigan company will transform the items of motor vehicle equipment into a motor vehicle. Therefore, the Michigan company would be a "manufacturer" of these vehicles for the purposes of the Safety Act and our regulations. Since 567.4(g)(1) requires the certification label to include the name of the manufacturer, the vehicles could comply if the name of the Michigan company were shown on the certification label. The information in your letter was inadequate to allow us to make even a tentative determination of whether LAFORZA may also be considered a manufacturer of these vehicles. The agency discussed the issue of vehicles with more than one "manufacturer" at length in its proposal to establish rules of attribution for determining which of the manufacturers would be responsible for complying with the phase-in requirements in Standard No. 208, Occupant Crash Protection (49 CFR 571.208). In that proposal, NHTSA said: Since the National Traffic and Motor Vehicle Safety Act places the responsibility of compliance with safety standards on manufacturers, the agency does not have authority to attribute a vehicle to a party other than one of the vehicle's manufacturers. However, the agency considers the language in section 102(5) of the Vehicle Safety Act that a manufacturer is "any person engaged in the manufacturing or assembling of motor vehicles . . ." to be sufficiently broad to include sponsors, depending on the circumstances. For example, if a sponsor contracts for another manufacturer to produce a design exclusively for the sponsor, the sponsor may be considered the manufacturer. This follows from application of basic principles of agency law. In this case, the sponsor is the principal. On the other hand, the mere purchase of vehicles for resale by a company which also is a manufacturer of motor vehicles does not make the purchaser the manufacturer of those vehicles. 50 FR 14589, at 14596; April 12, 1985. According to your letter, LAFORZA has a contractual relationship with the company in Italy that is producing the assemblage of items of motor vehicle equipment and a contractual relationship with the company in Michigan that is assembling the motor vehicle. These contractual relationships led you to assert that "... LAFORZA Automobiles will have complete control of the manufacturing process at all times." If LAFORZA merely has contractual relationships under which it purchases products for resale from the companies in Italy and Michigan, LAFORZA would not be considered the manufacturer of those vehicles. If you can provide us with information about any role LAFORZA has in producing these vehicles besides contracting with other companies to assemble the vehicles, we will review that information and offer our interpretation of whether LAFORZA could be considered a "manufacturer" of these vehicles for the purposes of the Safety Act and our regulations. Sincerely,

ID: 1992yOpen Commander Dear Commander: This is in reply to a letter of August 7, l989, from Jerry L. Dooley, Deputy Project Manager, Non-Line of Sight, with respect to "safety standards of the military nature", in particular those that would apply to the M1037 High Mobility Multipurpose Wheel Vehicle (HMMWV), as well as the M993 Bradley Fighting Vehicle System (BFVS). This agency has jurisdiction over all motor vehicles, defined as vehicles driven or drawn by mechanical power which are manufactured primarily for use on the public roads. Our principal role is the issuance of the Federal motor vehicle safety standards, and the monitoring of the notification and remedial campaigns of manufacturers upon the occurrence of noncompliances with the standards, or safety related defects in vehicles. We have never issued safety standards for military vehicles. Quite the opposite; although we interpret our authority as covering military vehicles, the agency has always specifically exempted from compliance with the standards any motor vehicles manufactured for, and sold directly to, the Armed Forces of the United States in accordance with contractual specifications. Frequently, military contracts for procurement of vehicles will call for their conformance with the Federal safety standards, when the nature of the vehicle is such (e.g. passenger car, bus) that conformance with the standards is not inconsistent with the configuration required to accomplish their mission. None of our safety standards for civilian vehicles cover driver field of view, basic visibility requirements, or ingress/egress. Our glazing standard does specify minimum levels of light transmittance, and our rearview mirror standard covers rear view mirror placement and rearward field of view. I am enclosing copies of these standards for your information. If you have further questions, we will be pleased to answer them. Sincerely, Stephen P. Wood Acting Chief Counsel Enclosures - Standards Nos. lll, 205 ref: 571.7 d:9/7/89 |

ID: 1993yOpen Mr. Taylor Hong Dear Mr. Hong: This is in reply to your letter with reference to motor vehicle flashers that you wish to sell in the United States. You have asked the following questions: l. "How do we get DOT approval?" 2. "Should ask for an application forms from you and sent one lot of samples for your test?" The Department has no authority to "approve" flashers, and no laboratory of its own in which it tests them. Under our law, the National Traffic and Motor Vehicle Safety Act, the manufacturer of the flashers, not the Department, determines in the first instance whether or not they comply with the SAE materials incorporated into Federal Motor Vehicle Safety Standard No. l08. If the manufacturer is convinced that they comply, it certifies that the flashers meet Standard No. l08, either with a statement on the container in which the flashers are shipped, a tag attached to each flasher, or a DOT symbol on the flasher itself. From time to time, the Department buys flashers for testing. In this manner, the Department has discovered that a number of those manufactured in Taiwan have not met Federal requirements, and lacked the required certification. In some instances, civil penalties have been imposed against the manufacturer or importer of the flashers. 3. "We may send samples to any other Laboratory and get an approval?" To aid you in reaching a conclusion whether the flashers are designed to conform with Standard No. 108, you may send samples to any test laboratory you wish. Although the standard deems a flasher compliant if not less than 17 of 20 flashers tested meet the requirements, we caution you that you should not accept such a result as a guarantor of compliance. Because of the tolerances involved in production of flashers, we believe that a manufacturer wishing to ensure that at least 17 of 20 flashers will pass whenever the government tests them should design its flashers to achieve a higher level of compliance with durability and performance requirements than the minimum acceptable number of 17. Once a higher level is reached, a manufacturer should ensure that the flashers will continue to meet Standard No. l08 over time. Accordingly, we urge flasher manufacturers to test their products periodically as an assurance that a minimum of 17 out of every 20 continue to meet the performance and durability requirements specified. Although you have no obligation to obtain "approval" from the Department, there are two requirements that manufacturers of flashers must meet before offering their products for sale in the U.S. You must designate an agent for service of process (49 CFR 551.45) and file an identification statement (49 CFR Part 566). I enclose a copy of these regulations for your information. If you have any further questions we shall be pleased to answer them. Sincerely,

ID: 19948.ztvOpenMr. Ron Dawson Dear Mr. Dawson: This is in reply to your e-mail of May 5, 1999, to Taylor Vinson of this Office, on kit cars. We had previously written you on this subject on March 29, 1999, and you have two further questions. I apologize for the delay in our response. In our earlier letter we informed you that we would regard the person installing the engine and transmission of a kit car, whether the kit purchaser or a commercial entity, as the manufacturer of the vehicle and responsible for its compliance with the Federal motor vehicle safety standards. You cite a letter from this Office to Kent Morris, dated April 22, 1991, in which we stated that a manufacturer is any person assembling more than one motor vehicle. Your asked whether we will "consider the kit purchaser who installs an engine and transmission into a single car a manufacturer." The answer is that the assembler of a single kit car is a "manufacturer." We have reviewed the statement you cited in our April 22, 1991 letter and concluded that it was incorrect. In other letters, we have stated that a purchaser who completes a kit is a manufacturer (see 1979 letter to the Honorable John C. Stennis) and that even if someone produces only a single motor vehicle, that vehicle must be certified to conform to all applicable Federal motor vehicle safety standards if its producer intends it to operate on the public roads (see 1997 letter to Mr. Dion A. DeVan). You note that 49 U.S.C. 30112 states that, with certain exceptions, "a person may not manufacture for sale, sell, offer for sale, introduce or deliver for introduction in interstate commerce, or import into the United States, any motor vehicle or motor vehicle equipment manufactured on or after the date an applicable motor vehicle safety standard . . . takes effect unless the vehicle or equipment complies with the standard . . . ." I would point out that driving a vehicle on the public roads would be considered an introduction into interstate commerce. Therefore, a person who assembled a kit car which did not comply with Federal motor vehicle safety standards and then drove the vehicle on the public roads would be in violation of this section. You also asked whether we would "enforce compliance upon a person who installs an engine and transmission in a kit car and then uses the completed motor vehicle for his/her personal highway use." If we should become aware of an apparent violation in such a situation, we would decide what action to take at that time. I would also note that, in addition to facing a potential Federal enforcement action, such a person might also be in violation of State laws. Moreover, in the event of a crash, there could be potential liability issues both for the assembler of the kit car and for the kit manufacturer. A local attorney could advise you about the laws of your state and potential liability issues. Sincerely, |

ID: 19951OpenMs. Sharon Elsenbeck Dear Ms. Elsenbeck: This responds to your April 28, 1999, letter that asks whether your residential treatment facility for "adolescents with emotional and behavioral problems" must transport its students by buses that meet the National Highway Traffic Safety Administration's (NHTSA's) school bus safety standards. You state that your residents attend an on-campus, non-public, school. By way of background, NHTSA is authorized to issue and enforce Federal motor vehicle safety standards applicable to new motor vehicles. Our statute at 49 U.S.C. 30112 requires any person selling or leasing a new vehicle to sell or lease a vehicle that meets all applicable standards. Accordingly, persons selling or leasing a new "school bus" must sell or lease a vehicle that meets the safety standards applicable to school buses. Our statute defines a "schoolbus" as any vehicle that is designed for carrying a driver and more than 10 passengers and which, NHTSA decides, is likely to be "used significantly" to transport "preprimary, primary, and secondary" students to or from school or related events. 49 U.S.C. 30125. By regulation, the capacity threshold for school buses corresponds to that of buses -- vehicles designed for carrying more than ten (10) persons. For example, a 15-person van that is likely to be used significantly to transport students is a "school bus." Our statute thus regulates primarily manufacturers and sellers of new school buses. Any person selling a new school bus must sell a vehicle that is certified as meeting our school bus standards. Conventional buses (including 15-person vans) are not certified as doing so, and thus cannot be sold, as new vehicles, under circumstances where they are likely to be used to carry students on a regular basis. You did not describe the program of Three Springs, so we are unable to determine whether your facility is a "school" under our statute. For your information, I am enclosing an April 8, 1998, letter to Mr. Gary Hammontree, director of a residential treatment program called Starr Commonwealth. The main purpose of Starr Commonwealth was to provide psychological and therapeutic counseling to youths placed in the program by the juvenile justice system. In our letter to Mr. Hammontree, we determined that Starr Commonwealth provided services that are distinct from the academic instruction associated with a "school," and that Starr Commonwealth was therefore not a school. Accordingly, we concluded that persons selling a new bus to the facility to transport the youths to counseling-related activities, such as service projects in the community, are not required to sell a "school bus." On the other hand, Starr Commonwealth also transported some students to off-campus public schools and events related to the schools. We therefore also determined that new buses sold to regularly transport students to those schools or to school-related events are "school buses" and would have to meet Federal school bus standards. As to whether you must use school buses, that question is answered by State law. Because our regulations apply only to the manufacture and sale of new motor vehicles, we do not prohibit facilities from using non-school buses to transport their pupils. Matters relating to motor vehicle use are determined by state law, so you should check North Carolina law to see what State requirements apply to your vehicles. For information on North Carolina's requirements, you can contact North Carolina's State Director of Pupil Transportation: Mr. Derek Graham, Section Chief In closing, we wish to emphasize that school buses are one of the safest forms of transportation in this country, and that we therefore strongly recommend that all buses that are used to transport school children be certified as meeting NHTSA's school bus safety standards. Further, using buses that do not meet NHTSA's school bus standards to transport students could result in increased liability in the event of a crash. Since such liability would be determined by State law, you may wish to consult with your attorney and insurance carrier for advice on this issue. I hope this information is helpful.

ID: 19975-1.pjaOpenMajor P.D. McClellan Dear Major McClellan: This responds to your letter asking for an interpretation of Federal Motor Vehicle Safety Standard No. 217, Bus Emergency Exits and Window Retention and Release. I apologize for the delay in responding. You ask whether Ohio's school bus construction standard is in conflict with our standard as to the location of side window emergency exits. Based on our understanding of your standard, our answer is no. You explain that your standard requires school buses with a seating capacity greater than 50 to have "two emergency swing out windows on the right and left side of the body" located in the front and rear third of the bus. Thomas Built Buses has told you that they have an interpretation letter from us stating that Standard No. 217 requires a window exit at the midpoint of the bus no matter how many exits are on each side of the bus. (Although you did not identify the letter, we believe you are referring to our August 4, 1995, letter to Ms. Jane L. Dawson of Thomas Built Buses.) You ask whether your standard may require the swing out windows in the front and rear third of the bus. S5.2.3.1 of Standard No. 217 requires school buses to be equipped with certain numbers and types of emergency exits, at specified locations. At the school bus manufacturer's option, a school bus may either have:
According to your letter, your school buses have a push-out rear window installed pursuant to S5.2.3.1(b). We gather from this that the two additional windows to which you refer are those described in Table 2, which permits manufacturers the option of installing the two window exits in lieu of a right side exit door. Our August 4, 1995, letter states that Standard No.217 does not specify a fore-aft location for a right side exit door or for window exits installed in lieu of a right side exit door. The letter states that these exit windows should be positioned fore-and-aft in the school bus so as to provide bus passengers with maximum accessibility to an emergency exit, in accordance with what is reasonable and practicable. We believe that your requirement that the two exit windows be placed on each side of the bus and in the front and rear thirds of the bus provides for appropriate accessibility. On this point, our standards are consistent. However, there are some potential differences between our standards that we would like to highlight.
Section 30103(b) of our statute, at 49 U.S.C. 30101 et seq., states:
To the extent that the Ohio requirements are different from those in Standard No. 217, their application to private school buses would be preempted. With respect to buses procured for the state's own use (including use by local school districts), the state standard is not preempted. The state standard results in no apparent reduction in the number of emergency exits and the locations appear to be reasonable and practicable. If you have any further questions, please contact us. Sincerely, |

ID: 19994.ztvOpenMr. F. Barry Hennegan Re: SS-99-10099 Dear Mr. Hennegan: This is in reply to your letter of May 3, 1999, to the Office of Chief Counsel, National Highway Traffic Safety Administration, "regarding possible exemptions from certain of the requirements of 49 C.F.R. Sections 571.121 and 393.52" with respect to two trailers owned by Lockheed Martin. The Office of Motor Carrier Safety, Department of Transportation, enforces 49 CFR 393.52. I am forwarding a copy of your letter to that Office for its response to you on this issue. In brief, Lockheed Martin is the owner of two trailers manufactured for it by Martinez and Turek of Riato, California. These trailers were manufactured to your specifications, which included compliance with Federal Motor Vehicle Safety Standard No. 121, Air brake systems. The trailers also feature steerable rear wheels mounted on a removable bogie assembly. You inform us that "after completion of acceptance and road testing of both trailers, it appears that neither will fully meet Section 571.121, Paragraphs S5.3.3 Brake actuation Time and S5.3.4 Brake Release time." However, you note that S3(a) of Standard No. 121 excludes trailers which exceed 102.36 inches in width and which are "equipped with two short track axles in a line across the width of the trailer." Your trailers are wider than this but don't meet the axle specification. Nevertheless, you believe that the intent of this exception is "not to have the requirements apply to oversize, slow, or specialty trailers such as ours." Accordingly, you ask that we exempt your trailers from S5.3.3 and S5.3.4 of Standard No. 121. I am sorry to inform you that we have no authority to exempt these trailers from Standard No. 121 under the circumstances that you relate. Because they are not equipped with two short track axles across their width, the trailers do not qualify for the exclusion from Standard No. 121 provided by S3(a). The trailers, then, were required by 49 U.S.C. 30112(a) to comply with all applicable Federal motor vehicle safety standards, and to be certified by their manufacturer as conforming to those standards. We have authority to exempt trailers from Standard No. 121 at any point up to and including their first sale for purposes other than resale, upon application by their manufacturer (49 U.S.C. 30113). Given the fact that these trailers are already owned by Lockheed Martin, it is too late for their manufacturer, Martinez and Turek, to apply for an exemption. When either we determine, or a manufacturer determines, that a motor vehicle fails to comply with a Federal motor vehicle safety standard, the manufacturer is required to notify us and its dealers and purchasers, and to remedy the noncompliance (49 U.S.C. 30118-30120, as implemented by 49 CFR Parts 573 and 577). However, if the manufacturer believes that the noncompliance is inconsequential to motor vehicle safety, it may petition us for a decision to that effect. If we grant the petition, the manufacturer is relieved of its statutory obligation to notify and remedy (49 U.S.C. 30118(d) and 30120(h), as implemented by 49 CFR Part 556). Therefore, if the manufacturer, Martinez and Turek, agrees that Lockheed Martin's trailers fail to comply with S5.3.3 and S5.3.4 of Standard No. 121, the company is required, at a minimum, to notify us in the manner prescribed in 49 CFR Part 573. Within 30 days of notifying us, it may also submit an inconsequentiality petition with us under 49 CFR Part 556. In this particular instance, the manufacturer might want to discuss, as part of such a petition, whether this vehicle is operated only under special permit and with escort vehicles. If it does not file a petition (or if the petition is denied), it is required to remedy the noncompliance. Although you did not address the issue, under our interpretations, the removable bogie assembly appears to be a trailer, and subject to compliance with Federal requirements. You state that the auxiliary axle was added after delivery of the trailers to ensure that the vehicles, when in use, would not exceed the maximum Colorado allowable rear wheel road loading for tandem axle trailers. A bogie/axle unit installed as part of a trailer's original equipment is considered to be part of the trailer itself, and covered by its manufacturer's certification and the trailer's VIN. However, a bogie/axle unit sold and installed after the trailer has been delivered to its owner is considered a trailer, and is required to comply with Federal requirements applicable to trailers, including compliance with Federal standards, the VIN regulation, and certification by the bogie/axle manufacturer. I am enclosing a copy of a letter we furnished Jay Reese on September 25, 1996, which explains this in further detail. If the bogie/axle units installed on your two trailers do not in fact comply with Federal standards applicable to trailers, the bogie manufacturer is subject to the same notification, recall, and inconsequentiality procedures discussed in the preceding paragraph. If you have any questions, you may phone Taylor Vinson of this Office (202-366-5263). Sincerely, cc: Martinez & Turek ref:121#573#555 |
