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.

President
Anthony Engineering & Technologies, Inc.
10189 W. Sample Road
Coral Springs, FL 33065

Dear Mr. Anthony:

This responds to your letter regarding regulations which may impact a tire pressure indicator.

You stated in your letter that your company is putting together a specification for an aftermarket tire pressure indicator ("indicator") that will indicate correct or low tire pressure on tires. A consumer would attach the tire pressure indicator to the tire valve in the same way a regular tire cap is attached. The material of the indicator will be a high strength high impact resistant "PET, similar to engineering plastics used for the beverage bottle industry for high pressure applications", which does not deteriorate with sunlight, smog, or humidity and will not break readily in a direct 50 mile per hour crash. You ask "whether there are any regulations that may impact the design of the indicator and what further considerations you may have deliberated in similar projects."

By way of background information, the National Highway Traffic Safety Administration (NHTSA) has the statutory authority to issue Federal motor vehicle safety standards (FMVSS) applicable to new motor vehicles and new items of motor vehicle equipment. Federal law establishes a self-certification system under which motor vehicle and equipment manufacturers themselves certify that their products comply with all applicable standards. For that reason, NHTSA neither tests, approves, disapproves, endorses, nor grants letters of approval of products prior to their introduction into the retail market. Rather, we enforce compliance with the standards by purchasing vehicles and equipment and testing them. We also investigate safety-related defects.

Turning now to the tire indicator, we would classify it as an item of motor vehicle equipment, defined in 49 U.S. Code (U.S.C.) 30102(a)(7)(B) as any "part or component manufactured or sold for replacement or improvement of a system, part, or component, or as an accessory or addition to a motor vehicle." Specifically, the indicator is an accessory if it meets the following criteria:

  1. A substantial portion of its expected uses are related to the operation or maintenance of motor vehicles; and
  2. It is purchased or otherwise acquired, and principally used by ordinary users of motor vehicles.

After reviewing your letter, we conclude that the tire indicator is an accessory. It was designed with the expectation that a substantial portion of its expected use will be with motor vehicles. Further, your description of the tire pressure indicator makes it clear that the indicator is intended to be purchased and principally used by ordinary users of motor vehicles to monitor tire pressure.

While the indicator is a motor vehicle accessory, NHTSA has not issued any FMVSSs establishing performance standards applicable to this product. However, the manufacturer, whether you or a licensee, is subject to the requirements of 49 U.S.C. 30118-30121 (copies enclosed) which set forth the notification and remedy (recall) procedures for products with defects related to motor vehicle safety. Thus, if NHTSA or the manufacturer determines that the product contains a safety-related defect, the manufacturer is responsible for notifying purchasers of the defective equipment and for remedying the problem free of charge.

Additionally, 49 U.S.C. 30122 (copy enclosed) provides that a manufacturer, distributor, dealer, or vehicle repair business may not knowingly "make inoperative" any device or element of design installed on or in a motor vehicle in accordance with any FMVSS. Therefore, the tire pressure indicator could not be installed by any one of those entities if such use would adversely affect the compliance of a vehicle with any FMVSS. This provision does not apply, however, to equipment attached to or installed on or in a vehicle by the vehicle owner.

I note that the Department's Federal Motor Carrier Safety Administration has jurisdiction over interstate motor carriers operating in the U.S. You should contact that office at (202) 366-1790, for information about any requirements that may apply to your product. In addition, states have the authority to regulate the use and licensing of vehicles operating within their jurisdictions. You should therefore check with the Department of Motor Vehicles in any state in which the equipment will be sold or used.

For your information, I am enclosing a fact sheet we prepared entitled Information for new Manufacturers of Motor Vehicles and Motor Vehicle Equipment, and Where to Obtain NHTSA's Safety Standards and Regulations.

I hope this information is helpful. If you have any questions or need additional information, feel free to contact Nancy Bell of my staff at (202) 366-2992.

Sincerely,
Frank Seales, Jr.

    Mr. Juergen Lucht
    WIKA Alexander Wiegand GmbH & Co (WIKA)
    Dept. GLZ-ID-QN
    D 63911 Klingenberg
    Germany

    Dear Mr. Lucht:

    This responds to your letter asking about Federal requirements for an air brake pressure hose fitting used in a gauge manufactured by your company. I am pleased to provide this information.

    By way of background, the National Highway Traffic Safety Administration (NHTSA) administers Federal requirements for the manufacture and sale of new motor vehicles and certain items of motor vehicle equipment, including brake hoses. NHTSA issues Federal motor vehicle safety standards applicable to new vehicles and equipment. Chapter 301 of Title 49 of the United States Code, "Motor Vehicle Safety" (49 U.S.C. 30101 et seq.), establishes a "self-certification" process under which each manufacturer is responsible for certifying that its products meet all applicable Federal motor vehicle safety standards. NHTSA tests vehicles and equipment for compliance with the Federal motor vehicle safety standards and investigates defects relating to motor vehicle safety. If a manufacturer or NHTSA determines that a noncompliance or safety-related defect exists, the manufacturer must notify purchasers of its product and remedy the problem free of charge. (This responsibility is borne by the vehicle manufacturer in cases in which an item of original equipment is installed on a new vehicle by the vehicle manufacturer.) A manufacturer of a noncomplying product is also subject to a civil penalty of up to $1,100 for each noncomplying item it produces. I have enclosed an information sheet that highlights the responsibilities you must meet as a manufacturer of motor vehicle equipment.

    Standard No. 106
    One of the standards we issued is Standard No. 106, "Brake Hoses," which applies to new motor vehicles and to brake hoses (which include plastic tubing), brake hose end fittings, and brake hose assemblies. The standard specifies labeling and performance requirements for these products to reduce the likelihood of brake system failure from ruptures in the brake hose or brake hose assembly. New brake hoses, end fittings, and assemblies must meet these requirements to be sold in or imported into this country. If the items do not comply, the manufacturer is subject to the civil penalties and the recall responsibilities mentioned above.

    From the information provided in your letter, it appears that WIKA manufactures a dashboard-mounted brake system pressure gauge which is connected to the brake system through a compressed air hose. Your letter did not provide sufficient information for us to offer an opinion as to whether the air lines and end fittings used with your product would be considered "brake hoses" and "brake hose end fittings" subject to the requirements of Standard No. 106, or whether an assembly of hose and end fitting would be a "brake hose assembly" as defined in the standard. Note, however, that it has been NHTSA's long-standing position that accessory air lines and end fittings, such as those used in your product, are "brake hoses" and "brake hose end fittings" if a failure of the line or fitting would result in a loss of pressure in the vehicle's brake system. (See the enclosed June 5, 1987, letter to Albert Schwarz, and the August 3, 1984, letter to Terry Teeter.) Accordingly, if a failure of the accessory lines or fittings used with your product could result in a loss of pressure in the brake system, the hoses, fittings and assemblies are subject to the provisions of Standard No. 106. Chapter 301 states that "a person may not manufacture for sale, sell, offer for sale, or introduce or deliver for introduction in interstate commerce, or import into the United States" any of the hoses, end fittings or assemblies unless the products comply with all of the applicable requirements in Standard No. 106.

    A copy of Standard No. 106 is enclosed. In addition, you may access this standard and other Federal motor vehicle safety standards through the NHTSA website at www.nhtsa.dot.gov.

    You ask several specific questions, which I will address below.

    Registration Requirements
    You first ask, "What are the usual procedures for a DOT registration like?" If you are asking about a pre-sale approval process, as explained above, NHTSA does not approve manufacturers' products or conduct pre-sale testing of their products. In the United States, the individual manufacturer must self-certify its product as complying with all applicable Federal motor vehicle safety standards.

    If you are asking about the labeling requirements of Standard No. 106, the standard requires manufacturers to label their brake hoses, end fittings, and assemblies with certain information, including a manufacturer's designation (see S7.2.1(b), S7.2.2(b), and S7.2.3(b)). The designation assists NHTSA in identifying the manufacturer of noncomplying or defective products. Assuming that your products are subject to Standard No. 106, the manufacturer must file its designation (which may consist of block capital letters, numerals or a symbol) in writing with NHTSA's Office of Vehicle Safety Compliance, National Highway Traffic Safety Administration, 400 Seventh Street, SW, Washington, DC 20590.

    Enforcing Standard No. 106
    You also ask how a manufacturer establishes conformity with our standards and whether a manufacturer may perform certification testing on its own or must use an independent test facility or qualified expert. As noted above, it is the manufacturer's responsibility to certify that its products meet all applicable standards. In meeting this responsibility, the manufacturer need not use an independent test facility and is not required to test in a particular manner. However, manufacturers must exercise due care when making the certification. Once your company has determined that the hoses, end fittings, and assemblies comply with the requirements of Standard No. 106, the standard requires you to mark these products with the symbol "DOT" to show your company's certification of compliance, as specified in the standard.

    This agency enforces the requirements of Standard No. 106 by purchasing brake hoses, end fittings, and assemblies. The certified products are tested by the agency according to the procedures specified in the standard. If the products pass these tests, no further actions are taken.

    Procedural Requirements
    I would like to discuss two procedural requirements you must meet to sell your products in this country. The first requirement is NHTSA's regulation for manufacturer identification (49 CFR Part 566). This regulation requires a manufacturer of equipment to which an FMVSS applies (e.g., brake hoses) to submit its name, address, and a brief description of the items of equipment it manufactures to NHTSA within 30 days after it first imports its products into the United States.

    The second requirement is NHTSA's regulation for designations of agents (49 CFR Part 551, Procedural Rules, Subpart D). The regulation requires all manufacturers headquartered outside of the United States to designate a permanent resident of the United States as the manufacturer's agent for service of all processes, notices, orders and decisions. This designation should be

    mailed to me at the following address: Chief Counsel, Room 5219, National Highway Traffic Safety Administration, 400 Seventh St., S.W., Washington, D.C., 20590. The designation must include the following information:

    1.   A certification that the designation of agent is valid in form and binding on the manufacturer under the laws, corporate-by-laws, or other requirements governing the making of the designation at the time and place where it is made;

    2.   The full legal name, principal place of business and mailing address of the manufacturer;

    3.   Marks, trade names, or other designations of origin of any of the manufacturer's products which do not bear its name;

    4.   A statement that the designation shall remain in effect until withdrawn or replaced by the manufacturer;

    5.   A declaration of acceptance duly signed by the agency appointed, which may be an individual, a firm or a United States corporation; and

    6.   The full legal name and address of the designated agent.

    In addition, the designation must be signed by a person with authority to appoint the agent. The signer's name and title should be clearly indicated beneath his or her signature.

    Fees or Costs
    Finally, you ask what fees or costs are required for registration and inspection. As noted above, NHTSA does not approve products prior to sale and would inspect a product as part of its compliance testing program. Manufacturers and importers of brake hoses are required to register with the agency and all importers and manufacturers of motor vehicles or motor vehicle equipment are required to meet the identification requirements, and importers are required to provide NHTSA with the identification of an agent for service of process. There are no fees associated with these requirements.

    I hope this information is helpful. Please feel free to contact Mr. Otto Matheke of this office at (202) 366-5253 if you have any further questions or need additional information .

    Sincerely,

    Frank Seales, Jr.

Mr. James T. Castle
Fleet Manager, Transportation Services
Clemson University
Klugh Avenue, Box 345382
Clemson, SC 29634-5382

Dear Mr. Castle:

This responds to your April 10, 2000, request for an interpretation of the National Highway Traffic Safety Administration's (NHTSA's) prohibition on dealers selling new 15-person vans for transporting children to or from school or related events. You wish to know whether the prohibition affects children in custodial care facilities such as summer camps. Our answer is provided below.

In a telephone conversation with Dorothy Nakama of my staff, you explained that by "summer camp" you mean that in the summer, Clemson University hosts children in the twelfth grade and below who want to improve their athletic skills. The children live at Clemson dormitories. Because of distances involved, the children may have to be transported between various sites (e.g., dormitory and athletic field) on the Clemson campus.

Some background information may be helpful. NHTSA is authorized to issue and enforce Federal motor vehicle safety standards (FMVSSs) 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." Persons selling or leasing new 15-person vans for such use must sell or lease a van that meets our school bus standards.

In the past, when reviewing a dealer's sale of a new vehicle, NHTSA looked at the nature of the institution purchasing the vehicle. In recent interpretations (see the attached July 17, 1998, letter to Mr. Greg Balmer of the YMCA), we noted that it was more appropriate to consider the extent to which the buses are used to carry children to or from school or related events. In the Balmer letter, we stressed that, even if a bus were sold to a facility that provides custodial care (i.e., to a facility that is not a "school"), if that facility were purchasing the new bus to use significantly to transport students to or from a school or events related to a school, a dealer knowing of this purpose would be required to sell a school bus.

Turning to your letter, you ask about vehicles that would be used to transport children in "summer camps." Based on the facts provided about Clemson University's "summer camp," we would not consider Clemson's "summer camp" as a "school" because apparently, no education is to be provided to the children. Since there would be no significant use of the vehicles to transport children to or from school or related events, a dealer knowing of this purpose that wishes to sell you a new bus (e.g., a 15-person van) would not have to sell you only a bus that meets our school bus standards.

Because our laws apply only to the manufacture and sale of new motor vehicles, we do not prohibit institutions such as your "summer camp" from using 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. For this reason, South Carolina law should be consulted to see if there are regulations about how children must be transported.

You asked for clarification of what "significant" means. There is no definitive answer to this question, but I have provided a basic guideline in an interpretation letter dated May 20, 1999 to Mr. Dennis Seavey of Plus Time New Hampshire (copy enclosed). The letter to Mr. Seavey explains that NHTSA considers "transportation provided to or from school on any two days during a week to be regular use and therefore 'significant.'"

In conclusion, 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 liability in the event of a crash.

I am enclosing NHTSA's publication: "School Bus Safety: Safe Passage for America's Children." This brochure explains the safety enhancements of a school bus that makes school buses safer than "conventional vans." There are small school buses available that seat 15 children. While school buses are more expensive than large vans, we believe that the cost difference is not so large that it should prevent facilities from acquiring school buses. The cost range for 15-person school buses is approximately $30-32,000, compared to $25-28,000 for 15-person vans. The longer service life for school buses will offset a part of this difference.

Our belief that vehicles providing the safety of school buses should be used whenever transporting children in buses is shared by the National Transportation Safety Board (NTSB). At a June 8, 1999, public meeting, the NTSB issued the attached abstract of a special investigative report on nonconforming buses. The NTSB issued the report after investigating four crashes in 1998 and 1999 in which 9 people were killed and 36 injured when riding in "nonconforming buses." NTSB defines "nonconforming bus" as a "bus that does not meet the FMVSSs specific to school buses." Most of the victims, including eight of the fatalities, were children.

In the abstract of its report, the NTSB issued several Safety Recommendations, including the following that was directed to child care providers such as the National Association of Child Care Professionals, the National Child Care Association, and Young Mens' and Young Women's Christian Associations:

Inform your members about the circumstances of the accidents discussed in this special investigation report and urge that they use school buses or buses having equivalent occupant protection to school buses to transport children.

I am also enclosing NHTSA's February 1999 "Guideline for the Safe Transportation of Pre-school Age Children in School Buses." This guideline establishes NHTSA's recommendations for how pre-school age children should be transported in school buses.

I hope this information is helpful. If you have any further questions about NHTSA's programs, please feel free to contact Dorothy Nakama of my staff at this address or at (202) 366-2992.

Mr. Randy Burns
Rt. 2, Box 267
Linden, TX 75563

Dear Mr. Burns:

We are replying to your e-mail of April 25, 2000, to Taylor Vinson of this Office. You relate that you have bought a set of "clear tail lamps" for use on your truck, which "state that they are dot approved." The units "have the red reflector." You are "using red bulbs in the lamps to make the lights red." You ask whether the lenses are legal.

In our view, the manufacture and/or sale of clear lenses intended for use on stop lamps or taillamps violates Federal law because they are not identical to the original lenses they are intended to replace, and would not provide a proper lamp color. We further advise that, under certain circumstances, installation of clear lenses on the rear of a motor vehicle could also violate Federal law. And as we have advised before, whether it is legal to drive a vehicle with clear lenses installed is a question to be answered under the laws in effect where the vehicle is driven. We have enclosed materials indicating that lamps with clear lenses and red bulbs are not legal in Texas.

The Federal requirements for motor vehicle lighting equipment are established by Federal Motor Vehicle Safety Standard No. 108, Lamps, Reflective Devices and Associated Equipment, which applies to lighting equipment on new vehicles, and replacement equipment for that original lighting equipment. Paragraph S5.8, Replacement Equipment, of Standard No. 108 requires lighting equipment manufactured to replace original lighting equipment to be designed to conform to Standard No. 108.

Under Table I and Table III of Standard No. 108 and appropriate SAE Standards incorporated by reference, the color of the light from taillamps and stop lamps must be red (If a manufacturer chooses red rather than amber for the rear turn signal lamp, the color from that lamp must be red as well. Rear clearance and identification lamps, and rear side marker lamps must also be red). The color red is defined by SAE Standard J578c, Color Specifications for Electric Signaling Devices, February 1977, which S5.1.5 of Standard No. 108 incorporates by reference. Although Standard No. 108 does not expressly state that the lens of a rear signal lamp must be red and the bulb white for the light to achieve the color red, we are unaware of any original equipment lamp required to emit the color red that consists of a clear lens and a red bulb and that is certified to comply with Standard No. 108. This is not simply a design choice; we know of no red bulb in production that conforms to Standard No. 108's color specification. The combination of a clear bulb and a red lens, therefore, is the only way to design a lamp that conforms to Standard No. 108's requirement that its light be red. This means that the manufacture of clear lenses or lamps intended to replace lenses or lamps on lamps whose original color was red is a violation of S5.8 of Standard No. 108, and the manufacture and sale of clear lenses or lamps for these purposes is a violation of 49 U.S.C. 30112(a). This means that the use of the DOT symbol on the lamp's lens or its container will be regarded as a violation of the certification provisions of 49 U.S.C. 30115. We shall maintain this position until we determine that a bulb conforming to the color red is in production, and specifically intended for use in lamps that will be certified as complying with Standard No. 108.

We contrast this with clear replacement lenses and lamps for turn signal and parking lamps (and front side marker lamps, as well as front clearance and identification lamps on wider vehicles). The light from these lamps must be amber (also when amber is chosen over red for the rear turn signals). The amber light from these lamps furnished as original equipment is produced by either a white bulb and amber lens, or by an amber bulb and a white lens. The latter is permissible because amber bulbs meeting J578's color specification for amber are available. Lamps incorporating white lenses and amber bulbs are being certified as conforming to Standard No. 108. Thus, a clear lens for these specific lamps is permissible as original equipment, provided that the lamp with an amber bulb produces light meeting J578's amber color specification. It follows that replacement lenses or lamps for original equipment lamps with amber bulbs may also be clear, and that it is not a violation of Federal law to manufacture and sell them, provided that they comply in every way with Standard No 108.

We also note that, if any replacement lens or the lens of a replacement headlamp is plastic, S5.1.2 requires it to conform to the specifications of SAE Recommended Practice J576, Plastic Materials for use in Optical Parts, Such as Lenses and Reflectors, of Motor Vehicle Lighting Equipment, JUL91. Since conformance is determined after a three-year outdoor exposure test, we have substantial doubts that any aftermarket clear plastic lens or lamp intended for replacement use on lamps required to produce red or amber light is manufactured from materials that have been tested in accordance with SAE J576 JUL91, as required for compliance with Standard No. 108.

You report that the clear lenses you bought incorporate a red reflector. One of our previous objections to clear replacement taillamp lenses was their lack of a red reflex reflector, present in many original equipment red taillamp lenses and which the vehicle manufacturer may have used to fulfill the requirement of Standard No. 108 that vehicles have red reflex reflectors on the rear, and if included in the original lamp, a red reflector on the side that fulfills the requirement for a red side reflex reflector.

You use the term "dot approved," but we have no authority to "approve" or "disapprove" vehicle lighting equipment, and such language is improper. We believe you must mean that the lenses are marked with a DOT symbol, or that the package in which they were sold stated "DOT approved." The use of the DOT symbol is reserved for representing the manufacturer's own certification that the lens or lamp complies with all applicable Federal motor vehicle safety standards, and not that we have approved the product. As noted above, we doubt whether manufacturers of these lenses have conducted the outdoor exposure test to which they may be certifying compliance by use of the DOT symbol. It is possible, also, that other tests for determining compliance have not been done as well.

At the beginning of my letter, I remarked that the installation of clear stop lamp and taillamp lenses could be a violation of Federal law under certain circumstances. Under 49 U.S.C. 30122, manufacturers, dealers, distributors, and motor vehicle repair businesses are forbidden from making inoperative any equipment installed in compliance with a Federal motor vehicle safety standard. If one of these persons replaces the original red lens by a white lens, we will consider that a violation of 49 U.S.C. 30122 has occurred, even if that person installs a red bulb.

However, this prohibition does not apply to an individual vehicle owner.

We enclose material that was published on June 8, 2000, on its internet website by the Texas Department of Public Safety which states that "clear tail lamp lenses utilizing red bulbs" are "in violation of Texas law."

If you have any questions, you may again contact Taylor Vinson by e-mail.

Dear Congressman Baldacci:

Thank you for your letter to the National Highway Traffic Safety Administration (NHTSA), on behalf of your constituent, Mr. David W. Keaton of Frenchville. Mr. Keaton, Director of the St. John Valley Technology Center, needs transportation for high school students who are participating in work-study programs at locations off the school campus. The students are transported by school bus from their high schools to the Center. Mr. Keaton is concerned about being able to provide transportation for students to go from the Center to various work sites. Because Maine's school transportation funds are limited, Mr. Keaton seeks to provide transportation by vans carrying 11 or more persons (including the driver) rather than by school bus. Mr. Keaton therefore seeks your assistance in:

  1. Allowing public school systems to operate any van without bus markings.
  2. Encouraging, through financial assistance, states to enable local educational units to use vans when transporting small numbers of students.
  3. Simplifying the school student transportation regulations to allow the transportation of school students in vans during the day.

At the outset, let me note that there is no federal regulation or statute that regulates how children must be transported. Requirements regulating how persons must be transported are determined by state law. However, NHTSA regulates which new buses dealers may sell or lease if the bus is used to regularly transport school children to or from school or school-related activities.

Some background information may be helpful. NHTSA is authorized to issue and enforce Federal motor vehicle safety standards (FMVSS) 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." Persons selling or leasing new 15-person vans for such use must sell or lease a van that meets our school bus standards.

It is my understanding that the high school students under Mr. Keaton's charge receive credits towards high school diplomas for participating in the work projects. Under these circumstances, we would consider the real-life work that students perform to be "school," and the transportation provided to the work site as school-related transportation. Therefore, when the students are being transported to the work sites in buses, we would recommend that they be provided school bus transportation.

Federal law also requires that any dealer that sells a new bus to the St. John Valley Technology Center that will significantly be used to take high school students to work sites, must sell a bus that meets NHTSA's school bus standards. Federal law supersedes any contrary state law that presumes to permit dealers to sell new non-school buses that will significantly be used to transport students to or from school or school-related activities. (See 49 U.S.C. 30103(b), Preemption.)

Because our laws apply only to the manufacture and sale of new motor vehicles, we do not prohibit schools from using 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. For this reason, if Mr. Keaton wishes to change regulations or procedures for the use of Maine school vehicles, he must look to Maine state law. One person Mr. Keaton should consult is Maine's State Director of Pupil Transportation, Mr. Harvey Boatman, who can be reached at (207) 287-5321.

Mr. Keaton's first point is that public school systems should be permitted to operate any van without bus markings. Bus marking requirements are addressed by state law. Mr. Keaton's second point (encouraging, through financial assistance, states to enable local educational units to use vans when transporting small numbers of students) and third point (simplifying the school student transportation regulations to allow the transportation of school students in vans during the day) also ask for changes in state vehicle use requirements, and must therefore be reviewed by Maine state officials. However, 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 liability in the event of a crash.

I hope this information is helpful. If you have any further questions, please contact Mr. John Womack, Senior Assistant Chief Counsel, at (202) 366-9511.

Dear Mr. King:

This is in reply to your letter of April 24, 2000, asking for a clarification of our views on photometric test requirements for multi-compartment rear combination lamps.

You ask whether it is correct to say that a rear combination lamp system (stop lamp, turn signal lamp, taillamp) which consists of lamps on both the rear deck lid and fender which have the appearance of a single lamp with multiple compartments may be considered two lamps because they are not physically connected. If this is the correct interpretation, you then ask for confirmation that the fender-mounted lamp is the lamp that must meet all photometric requirements applicable to stop lamps, taillamps, and rear turn signal lamps.

We confirm your interpretation as it pertains to the rear combination lamp system you describe. Even though a lamp system design may have the appearance of a single lamp with multiple compartments, the system cannot be considered a single lamp when it is mounted both on the deck lid and adjacent fender. It is impossible for the two portions to share a common housing or lens because the housing and lens must be separated in order for the deck lid to open. Thus, the system you describe consists of two lamps. As we have indicated in previous interpretations, we regard the combination lamp that is mounted on the body as the one that must be designed to comply with Standard No. 108. This is because a body-mounted lamp will be visible at all times, whereas one on the deck lid will not be in its design orientation should the deck lid be ajar when the vehicle is in operation, such as may occur when the driver is carrying a load.

You have also referred to the requirement in S5.3.1 of Standard No. 108 that lighting equipment be mounted on a rigid part of the vehicle, and asked whether the deck lid can be considered a "rigid part." Yes, the deck lid is a rigid part. This specification was adopted primarily to forestall installation of rear reflex reflectors on mud flaps. However, consistent with the discussion in the prior paragraph, in terms of your design, we consider the second lamp to be supplemental lighting equipment because all items required by Standard No. 108 must be mounted on the body. This supplemental lamp may be mounted on the deck lid because the complying lamp will remain in its design orientation regardless of the position of the deck lid.

If you have any questions, you may phone Taylor Vinson of this Office (202-366-5263).

Sincerely,
Frank Seales, Jr.

Dear Mr. Weiman:

This responds to your May 2, 2000, letter asking for assistance in locating information pertaining to the marketing, testing, application and certification of a particular type of Michelin tire: Michelin XM + S 244 Reinforced Radial X, size 205R16 104T.

By way of background information, the National Highway Traffic Safety Administration (NHTSA) has the statutory authority to issue Federal motor vehicle safety standards (FMVSSs) applicable to new motor vehicles and new items of motor vehicle equipment. Pursuant to this authority, we issued a number of standards for tires. All new tires sold in the United States for use on passenger cars must be certified by the manufacturer as complying with FMVSS 109, New pneumatic tires, found at 49 CFR 571.109, while all new tires sold for use on motor vehicles other than passenger cars must be certified as complying with FMVSS 119, New pneumatic tires for vehicles other than passenger cars (49 CFR 571.119). All retreaded passenger car tires must be certified as complying with FMVSS 117, Retreaded pneumatic tires (49 CFR 571.117). We also have authority to investigate safety-related defects in motor vehicles and items of motor vehicle equipment, including tires.

The Uniform Tire Quality Grading Standards (UTQGS) are set forth in 49 CFR 575.104. Those standards do not require certification in the same manner as the FMVSSs. The UTQGS require that manufacturers mold onto or into the sidewalls of their tires the comparative rating of those tires for treadwear, traction, and temperature resistance for the use and benefit of consumers.

Finally, 49 CFR 574.5 requires each tire sold in the United States to have a tire identification number (TIN) molded into or onto the tire sidewall by the manufacturer to facilitate recall in the event of a noncompliance or defect.

Our statute establishes a self-certification process applying to the manufacture of vehicles and equipment to our safety standards. This means that NHTSA does not perform any pre-sale testing, approval, or certification of tires, whether of foreign or domestic manufacture, before their introduction into the U.S. retail market. Instead, each tire manufacturer must certify that its tires comply with applicable FMVSSs. We do not require that a manufacturer base its certification on any specific test or on any number of specified tests. However, manufacturers must exercise due care in certifying its tires. It is the responsibility of each tire manufacturer to determine what tests results, computer simulations, engineering analyses, or other information it needs to enable it to certify, with due care, that its tires comply with applicable Federal tire safety standards.

Once a manufacturer has determined that its tires meet all applicable Federal safety standards, it certifies such compliance by molding the letters "DOT" onto at least one sidewall of each certified tire. If manufacturers conduct any tests, they are not required by Federal law or regulation to release their test results to the public.

NHTSA tests certified tires to determine whether the tires do, in fact, comply with applicable standards. For such enforcement checks, NHTSA purchases tires "off the shelf" from retail tire dealers or distributors and tests those tires according to the procedures specified in the standards. Those test reports are made public. If the tire passes the tests, no further action is taken. If it fails the tests and is determined not to comply with any applicable standard or standards, the manufacturer is responsible for recalling the tires and remedying the noncompliance without charge to the consumer.

As discussed in correspondence to you dated June 8, 2000, from NHTSA's Office of Vehicle Safety Compliance, no compliance or defect reports have been located for the tire type and size you specified.

I hope this information is helpful. If you have any questions or need additional information, feel free to contact Nancy Bell of my staff at (202) 366-2992.

Mr. Michael L. Wagner
563 Circle Drive
Fairmount, IN 46928-1963

Dear Mr. Wagner:

This is in reply to your fax of May 16, 2000, to Taylor Vinson of this Office. You had talked with him on the 15th regarding modulating motorcycle headlamps, reporting that you are "frequently being pulled over by Indiana State Police telling me it is illegal." You also informed him that you had bought your modulating unit in the aftermarket, and that it was not original equipment on your motorcycle.

I am enclosing three of our interpretive letters setting forth legal opinions of this Office on modulating headlamps. They are addressed to Tracey Wagner of the American Motorcyclist Association (February 1, 1990), Walter Jakobowski of Signal Dynamics Corporation (September 11, 1997), and Henry Winokur (January 21, 1999).

In brief, S.7.9.4, Motorcycle headlamp modulation system, of Federal Motor Vehicle Safety Standard No. 108, Lamps, Reflective Devices, and Associated Equipment, permits, but does not require, the installation of a modulating headlamp system as original lighting equipment on motorcycles, provided that the system meets the performance requirements of S7.9.4. Under S5.8, replacement lighting equipment (which includes a modulator sold in the aftermarket) must be designed to conform to the same requirements as original equipment, and to be certified by its manufacturer as complying with these requirements. Federal law (49 U.S.C. 30103(b)) specifies that, when a Federal motor vehicle safety standard is in effect, a state may not have a different standard covering the same aspect of performance as the Federal standard. This means that any state law covering modulating headlamp systems on motorcycles cannot prohibit such systems or prescribe different performance requirements than those that appear in Standard No. 108.

Many states reserve the use of flashing lights for emergency vehicles. S4 of Standard No. 108 defines the word "flash" in part as a continuing "cycle of activation and deactivation." The cycle required for modulating headlamps, on the other hand, involves going from a higher intensity to a lower intensity, and the lamp is never deactivated. Thus, a headlamp modulating in accordance with S7.9.4 does not "flash" within the meaning of the Federal lighting laws. If the modulating headlamp system on your motorcycle meets Federal requirements, it should be permitted for use in any state under the preemptive language of Section 30103(b).

If you have further questions, you may phone Taylor Vinson (202-366-5263).

Frank Seales, Jr.

    Dear Mr. Frederick:



    This responds to your letter asking about Federal requirements for air bags. You are representing an individual who was seriously injured in a crash where the air bag in his 1995 passenger car failed to deploy. You stated that the automaker is denying liability "based on its Technical Analysis Group's review and conclusion 'the direct frontal collision forces were not within the threshold for deployment', and thus SRS deployment not warranted; even though the impact was well within 30 degrees of direct center of the vehicle." You asked whether there are any regulations governing air bag deployment and the conditions for deployment. Your question is addressed below.

    By way of background information, the National Highway Traffic Safety Administration (NHTSA) issues Federal motor vehicle safety standards covering new motor vehicles and new motor vehicle equipment. One of the standards we issued, Standard No. 208, Occupant Crash Protection (49 CFR 571.208) required 1995 passenger cars to provide automatic crash protection. Vehicles equipped with automatic crash protection protect their occupants by means that require no action by vehicle occupants. The only two systems used to meet this requirement were air bags and automatic seat belts. An amendment to Standard No. 208 made air bags mandatory in all passenger cars and light trucks in the late 1990's.

    Among other things, Standard No. 208 specifies that vehicles meet certain performance requirements in crash tests. These tests are conducted with instrumented test dummies placed in the front outboard seating positions of the vehicle. During the tests, the forces measured on the dummies may not exceed specified limits. However, the standard does not specify any crash severity threshold where the air bag must, or must not, deploy.

    You also expressed interest in a list of vehicles that were recalled for defective air bags. NHTSA's Office of Defects Investigation has previously provided that list.

    I hope this information is helpful. If you have any further questions, please feel free to call Edward Glancy of my staff at 202-366-2992.
