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.

Mr. Jeffrey T. Morris
Director of Human Resources
George Junior Republic
P. O. Box 1058
Grove City, PA 16127

Dear Mr. Morris:

This responds to your request for an interpretation whether George Junior Republic, a "non-profit residential treatment facility," must use school buses to transport youth under its care. As explained below, we do not consider the residential treatment program to constitute a "school" as that term is used in our statute. However, to the extent you transport the pupils to athletic and other events related to the public school located at your facility, a new bus that is sold for such purposes may have to be a school bus, depending on how regularly the vehicle is used for the school-related transportation. You should also keep in mind that the States regulate the registration and use of vehicles in their jurisdictions. You should therefore consult Pennsylvania law to see what requirements, if any, apply to how your youth are to be transported.

Your letter explains:

George Junior Republic is a non-profit residential treatment facility located in Grove City, Pennsylvania. We provide residential care to approximately 460 teenagers who are adjudicated delinquent or dependent and court ordered into treatment for care and rehabilitation. ... All of our students are educated by Public School Systems. The residents attend a school located on our campus which is operated and governed by the Grove City Area School District. These students walk to and from school so transportation is not a problem.

You also explain that each youth lives in a campus home with seven other youths, headed by a married couple who are the counselor/parents. The youths with their counselor/parents may attend off-campus activities that require transportation. In addition, you explained to Dorothy Nakama of my staff that George Junior Republic youth participate in athletic competitions with other schools in the Grove City Area School District. They are also occasionally taken on field trips for academic purposes.

Some background information on our requirements may be helpful. The National Highway Traffic Safety Administration (NHTSA) is authorized to issue and enforce Federal motor vehicle safety standards applicable to new motor vehicles, including school buses. In 1974, Congress enacted legislation directing NHTSA to issue safety standards on specific aspects of school bus safety, and to apply those standards to all school buses. Our statute defines a "school bus" as any vehicle that is designed for carrying 11 or more persons and which is likely to be "used significantly" to transport "preprimary, primary, and secondary" students to or from school or related events (emphasis added). 49 U.S.C. 30125. Our statute at 49 U.S.C. 30112 requires any person selling or leasing a new "school bus," which may include a 15-passenger van, to sell or lease a vehicle that meets the Federal school bus safety standards. The seller risks substantial penalties if he or she knowingly sells a vehicle for use as a school bus and the vehicle is not certified as such.

Your letter raises two questions. First is whether George Junior Republic's residential treatment program constitutes a "school." This question is one the agency finds appropriate to resolve case-by-case, focusing on the type of services provided by the organization at issue.

The facts you have provided show that George Junior Republic primarily provides psychological and therapeutic counseling and other social services for the youngsters. For purposes of NHTSA's safety standards, I have concluded that these services are distinct from the academic instruction associated with a "school," and that therefore, George Junior Republic is not a "school." (This finding is consistent with NHTSA's April 8, 1998, letter to Mr. Hammontree of Starr Commonwealth, a residential treatment facility whose program appears similar to that of George Junior Republic.) Thus, if a dealer were to sell a new bus to George Junior Republic for purposes of transporting youth to social services activities relating to the rehabilitation of your clients, the dealer need not sell a school bus.

The second issue is whether school buses are required in transporting George Junior Republic youngsters to and from events related to the public schools, e.g., athletic competitions with other Grove City schools, and school-related field trips.

From your letter, we are unable to estimate the extent of transportation for "school-related" activities versus non-school related activities (such as outings with parent/counselors and others for recreational or rehabilitation purposes). Please note that we consider any bus that is likely to be "used significantly" to transport students to or from school or related events a "school bus." If your buses are only occasionally used for school-related events, such use would not be significant. However, if your vehicles are used on a regular basis to transport students to school-related events, the buses would be school buses. Any person selling a new bus (including 15-passenger vans) for regular use transporting students to school-related events would be required to sell a certified school bus.

Please note that Federal law and NHTSA's safety standards directly regulate only the manufacturer and seller of new motor vehicles, not individual users. Federal law does not prohibit owners from using their vans to transport school children, regardless of whether such vans meet the Federal school bus safety standards. However, the states have the authority to regulate the use of motor vehicles, including school vehicles, and your state may have restrictions on the types of vehicles you may use. Thus, you should consult Pennsylvania law as to whether Pennsylvania has requirements for the vehicles you use for carrying clients to social services programs, or to school-related events.

James B. Cantwell, Esq.
Assistant Commissioner and Chief Counsel
State of New York
Department of Transportation
Albany, New York 12232

Dear Mr. Cantwell:

This responds to your letter of May 12, 1998 asking that the National Highway Traffic Safety Administration (NHTSA) find that buses ordered by two private high schools on Long Island are eligible to be recertified as a school buses. Your letter explains that in February 1998, the two high schools, Chaminade and Kellenberg, ordered a total of six new 21-passenger buses to transport their sports teams. The letter explains that all six buses have been manufactured, that each bus was certified under 49 CFR Part 567 as a "bus," and that all of the buses were to have been delivered to the distributor by the week of May 18. Your letter goes on to state:

The attached letter from Goshen Coach [the bus manufacturer] indicates these buses appear to comply with NHTSA's Part 571 school bus standards in all required areas, except for 571.131 (School Bus Stop Arm) and 571.222 (School Bus Seats). The distributor has advised us that it is prepared to install a school bus stop arm that satisfies Section 571.131 and believes that the installed seats, manufactured by Freedman Seating Company of Chicago, IL address the requirements of Section 571.222.

It is not completely clear from your letter who will be taking the final steps to conform the buses to the vehicle safety standards applicable to school buses. At the point the buses are delivered to the schools, they will have to be certified as complying with these standards. Goshen Coach and its distributor are evidently aware that the standards applicable to school buses differ from those applicable to other buses with respect to several aspects of performance. In addition to the standards for stop arms and seating, there are also requirements for school bus windows, exits, lighting, mirrors, rollover protection, fuel system protection, and the strength of bus body joints. Your letter suggests that some equipment subject to these requirements may be installed before Goshen Coach delivers the buses to its distributor (e.g., the seats) and other equipment may be installed by the distributor (e.g., the stop arms).

Under the regulatory framework established by Chapter 301 of Title 49, United States Code, the manufacturer of a vehicle must certify that a vehicle complies with the standards applicable to it. If Goshen's distributor installs equipment that relates to the buses' compliance with the standards before it delivers the buses to the schools, the distributor would be considered an alterer under our regulations and would share responsibility with Goshen for the final certification of compliance with the standards. There is no requirement under Chapter 301 for prior approval by NHTSA, nor does the agency issue such approvals. However, if NHTSA tests a vehicle and finds that it does not comply with a standard, it can require the manufacturer to recall the vehicle and remedy the noncompliance at no cost to the vehicle owner. Chapter 301 also specifies a civil penalty of up to $1100 for each noncompliance.

Although Norman Schneider of the New York State Department of Transportation has provided us general information about the buses in question, we are not in a position to decide whether the buses comply with the school bus standards. Goshen Coach and its distributor have represented that the buses call be brought into full compliance with NHTSA's school bus standards by the addition of the stop arms and the seats that Freedman Seating Company has installed. If Goshen Coach and its distributor, upon modifying the buses, believe that the buses meet the standards applicable to school buses, and certify under 49 CFR Part 567 that the buses meet the standard, the buses could be sold and delivered to the high schools.

Goshen Coach and its distributor should be aware that before they certify the buses they must exercise reasonable care to ensure that the buses, in fact, meet the standards, and that they would be responsible for remedying any vehicle subsequently found to be in noncompliance.

I hope that you find this responsive to your request. I am enclosing a November 2, 1992 NHTSA interpretation letter to Aetna Life Insurance Co., that lists the requirements applicable to school buses in greater detail. 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.

John Womack

2256 Heitman Street
Fort Myers, FL 33901-3744

Dear Mr. Roberts:

This is in response to your letter requesting information about standards for motorcycle helmets, particularly those manufactured after 1980. In addition to information relating to standards for motorcycle helmets, you have also asked if the agency maintains records of helmets that have been recalled and how you might obtain copies of these records.

By delegation from the Secretary of the U.S. Department of Transportation (DOT), NHTSA is the Federal Government agency responsible for improving safety on our Nation's highways. As part of our efforts to achieve that goal, we are authorized, pursuant to 49 U.S.C. 30111, to issue and enforce Federal motor vehicle safety standards (FMVSS). These standards require minimum levels of performance for new vehicles and items of motor vehicle equipment. Pursuant to this authority, NHTSA has promulgated FMVSS No. 218, "Motorcycle Helmets," which applies to all helmets designed for highway use by motorcyclists. Pursuant to 30012(a) of Title 49, it is unlawful to manufacture for sale, sell, offer for sale, introduce or deliver for introduction into interstate commerce, or import into the United States any motor vehicle or item of motor vehicle equipment that does not comply with all applicable safety standards, including Standard 218.

I have enclosed a copy of the current version of Standard 218 for your use. The Standard is also available in Volume 49 of the Code of Federal Regulations at 49 CFR 571.218. If you have access to the World Wide Web, the Code of Federal Regulations can be found at http://www.nara.gov.

Standard 218 was first promulgated in 1973 and amended in 1974, 1980, and 1988.

The performance requirements of Standard 218 remained unchanged from 1973 until 1988. The original version of the Standard applied to all helmets designed for highway use by motorcyclists. However, through a final rule published in the Federal Register on January 28, 1974 (39 FR 3554), the Standard was amended to restrict its application only to helmets that fit on a specific headform, known as the size "C" headform. This amendment was necessitated by difficulties in developing appropriate different sized headforms for testing. However, as these difficulties continued, the agency concluded that a precise fit was not as critical for testing purposes as had previously been thought and the "C" headform could be used more widely. Therefore, Standard 218 was again amended on March 10, 1980 (45 FR 151181) to apply to all helmets that could be placed on the "C" headform even if the helmet did not precisely fit that headform. After other difficulties with test headforms were finally resolved, the Standard was amended again on April 6, 1988 (53 FR 11280) to apply to all helmets designed for highway use by motorcyclists. The 1988 amendments also modified the performance requirements of Standard 218 in regard to the areas of the helmet subject to penetration and impact testing, temperature conditioning prior to testing and the properties of the test devices used to perform testing. Copies of each of the notices implementing these amendments are enclosed.

Information related to helmet recalls may be obtained from NHTSA's office of Technical Information Services (TIS). You may contact TIS at this address:

Slatington, PA 18080

Dear Mr. Rentschler:

This responds to your request for an interpretation whether a dealer may sell a new van that seats fewer than 11 persons to a school, for use in transporting school children. Such a van is a multipurpose passenger vehicle (MPV) under our regulations. As explained below, the National Highway Traffic Safety Administration (NHTSA) does not prohibit a dealer from selling a new MPV for such a purpose.

By way of background, NHTSA is authorized to issue and enforce Federal motor vehicle safety standards applicable to new motor vehicles, including school buses. Any person selling a new vehicle must sell a vehicle that meets all applicable standards. Under our regulations, a "bus" is a vehicle that has a seating capacity of 11 persons or more. A "school bus" is a "bus" that is sold for purposes that include carrying school children to or from school or related events (49 C.F.R. 571.3). Because any new "bus" that is sold for pupil transportation purposes is a "school bus," the school bus standards apply, and any person selling such a vehicle must ensure that the vehicle is certified as meeting our school bus standards.

We do not require, however, that only school buses can be sold for pupil transportation. Under our regulations, a van that seats fewer than 11 persons is an "MPV," which is defined in 571.3 as a motor vehicle "designed to carry 10 persons or less which is constructed either on a truck chassis or with special features for occasional off-road operation." An MPV is a different type of vehicle than a bus or a school bus, and must meet safety standards that apply to MPVs. Dealers selling new MPVs must be sure to sell vehicles that have been certified to the MPV standards. Manufacturers may voluntarily manufacture MPVs to meet school bus standards on aspects of performance that do not conflict with MPV standards, such as emergency exits, joint strength, and roof crush.

Please note that Federal law and NHTSA's safety standards directly regulate only the manufacture and sale of new motor vehicles, not their use. Each State is free to impose its own standards regarding use of motor vehicles for pupil transportation, including MPVs or school buses.

NHTSA has issued guidelines for States to use in developing their highway safety programs. NHTSA has issued Highway Safety Program Guideline 17, Pupil Transportation Safety (copy enclosed), to provide recommendations on various operational aspects of State school bus and pupil transportation safety programs. Each State determines the extent to which it adopts the recommendations in Guideline 17.

Dear Mr. Dugan:

This is in reply to your letter of May 14, 1998, to the New York Regional Office of this agency, with respect to a lighting device that you wish to offer to funeral directors. This device is a battery operated lamp, 3 inches in diameter, intended to be attached by a magnet or suction cup to the roofs of cars in funeral processions. The lamp, which emits a white color, flashes, with the intent of assisting drivers in the procession to stay together. You also note your belief that, with the advent of daytime running lamps, headlamps alone "are no longer a sufficient identifier of a funeral procession." You have asked if we have any objection to the use of these lamps.

The use of these lamps would not violate any Federal statute or regulation. They are subject to the laws of the State or municipality in which they will be used. Some jurisdictions may prohibit the use of flashing lights except on police or emergency vehicles. However, we are not conversant with local laws and are not able to advise you about them.

Because our interpretations are a matter of public record, I would like to explain briefly, without legal citations, how we reached our conclusion that the use of these lamps is not prohibited under Federal law. A flashing white lamp cannot be installed on a new motor vehicle, before its first sale, because all lamps must be steady burning, except for turn and hazard warning signals, school bus warning lamps, and headlamps that flash for signaling purposes. After the first sale of a vehicle, the lamp could not be attached by a manufacturer, dealer, distributor, or motor vehicle repair business because that would make inoperative the Federal lighting standard that applied to the vehicle when it was new. But this prohibition covers only the entities named, and installation of the flashing lamp by a person other than the entities named is not prohibited. That is to say, an employee of a funeral home or the owner of a vehicle in the procession can install the lamp without violating Federal law.

Frank Seales, Jr.

P.O. Box 2639
Springfield, VA 22152

Dear Ms. Finkel:

This responds to your recent letter to my office asking whether school buses used by school bus contractors regulated by the Federal Highway Administration (FHWA) must have push-out windows, even when those buses are used for purposes other than school transportation.

The answer to your question depends on the effect of our and FWHA regulations on the vehicles in question. We will only address the effect of NHTSA's requirements in this letter, and will ask FHWA to reply to you directly on FHWA requirements for push-out windows.

Under NHTSA's requirements, the answer is no. As you know, the buses you describe would have to comply with our Federal motor vehicle safety standards (FMVSS's) for school buses if they are sold as "school buses," i.e., for purposes that include carrying students to and from school or related events. (49 CFR /571.3) The determination of the intended use of the vehicle would be made at the time the new vehicle is first sold to the "school bus contractors." Any person selling the new buses to the contractors who knows that the vehicles would be used as school buses would be required to sell complying school buses. Since vehicles need only meet the FMVSS's applicable to their vehicle type (e.g., "school buses"), the school buses need not meet FMVSS's for non-school buses, even though the school buses might also be used for purposes other than school transportation. Conversely, any person selling a bus to a contractor knowing that the bus would not be so used, would not be required to sell a complying school bus.

FMVSS No. 217, Bus Window Retention and Release, does not generally require push-out windows for school buses, except a push-out rear window is required if a manufacturer decides to satisfy FMVSS No. 217's school bus emergency exit requirements by selecting the option (S5.2.3.1(b)) that calls for such a window.

Further, FMVSS No. 217 does not require push-out windows for non-school buses. The agency proposed to require push-out windows for non-school buses early in the rulemaking history of Standard No. 217 (35 FR 13025; August 15, 1970), but decided against such a requirement because devices other than push-out windows appeared to be effective for emergency egress. 37 FR 9394; May 10, 1972. Thus, new buses sold to bus operators for non-school bus purposes need not have push-out windows under Standard No. 217.

For your information, NHTSA has issued an advance notice of proposed rulemaking (53 FR 44623; November 4, 1988) to review Standard No. 217's emergency exit requirements for school buses. Among the issues under consideration by the agency is the desirability of a requirement for push-out windows. NHTSA is presently reviewing the comments received on the notice. A copy of the notice is enclosed.

In summary, a new bus sold for purposes that include carrying school children must meet our FMVSS's for school buses. This is so even if the bus is also used for non-school purposes. Our FMVSS's for school and non-school buses do not now generally require push-out windows.

We expect the FHWA will provide you with an interpretation of their requirements for push-out windows shortly.

Sincerely,

Erika Z. Jones Chief Counsel

Mercedes-Benz of North America, Inc.
One Mercedes Drive, P.O. Box 350
Montvale, NJ 07645-0350

Dear Mr. Selke:

This responds to your letter asking whether the National Highway Traffic Safety Administration (NHTSA) will exercise its discretion not to institute enforcement proceedings with

respect to special seat belt installations in a 1996 E320 Mercedes-Benz and a 1998 S420V Mercedes-Benz. I apologize for the delay in my response. In a telephone conversation with Nicole Fradette of my staff you explained that the extra-long belt assemblies were needed to accommodate two of your customers in the following circumstances. You explained that the owner of the 1998 S420V Mercedes-Benz has a driver and would like an extended length seat belt installed in the right-rear passenger seat so that he may lean forward to use the phone while seated in the back of the car. You also explained that the owner of the 1996 E320 Mercedes-Benz needed an extended length seat belt to accommodate a severely obese right front-seat passenger. You explained that the passenger is extremely obese and cannot use the passenger-side seat belt because of his large body size and that your special order 12-inch longer belt is still too short to fit him. You explained that your factory has supplied longer seat belts, but that the extra-long belt assembly will not comply with the following aspects of Standard No. 209:

  • the seat belt will not completely roll up into the B-pillar due to excessive webbing on the spool;
  • the seat belt has not been tested for retraction spring durability and therefore may not pass the retractor cycle test;
  • no certification label is attached.

As explained below, our answer is that the extra-long seat belt assembly may be installed in the 1996 E320 Mercedes-Benz but may not be installed in the 1998 S420V Mercedes-Benz. The

National Highway Traffic Safety Administration (NHTSA) will not institute enforcement proceedings against a dealer that installs the longer seat belt assembly in the 1996 E320 Mercedes-Benz to accommodate an extremely obese passenger. A more detailed answer to your letter is provided below.

As you are aware, our agency is authorized to issue Federal motor vehicle safety standards that set performance requirements for new motor vehicles and items of motor vehicle equipment. Manufacturers are required to certify that their products conform to our safety standards before they can be offered for sale. After the first sale of the vehicle, manufacturers, distributors, dealers, and repair businesses are prohibited from "knowingly making inoperative" any device or element of design installed on or in a motor vehicle in compliance with an applicable standard. In general, the "make inoperative" prohibition (49 U.S.C. 30122) requires businesses which modify motor vehicles to ensure that they do not remove, disconnect, or degrade the performance of safety equipment installed in compliance with an applicable standard. Violations of this prohibition are punishable by civil penalties of up to $1,100 per violation.

There is no procedure by which businesses petition for and are granted permission from NHTSA to modify a motor vehicle. Businesses are permitted to modify vehicles without obtaining permission from NHTSA to do so, but are subject to the make inoperative provision of 49 U.S.C. 30122. In certain limited situations, we have exercised our discretion in enforcing our requirements to provide some allowances to a business which cannot conform to our requirements when making modifications to accommodate the special needs of persons with disabilities.

As you noted in your letter, removing the original seat belt assemblies and replacing them with the longer seat belt assemblies would affect the vehicles' compliance with Standard No. 209, Seat belt assemblies. In certain limited situations, such as with the 1996 E320 Mercedes-Benz, where a vehicle must be modified to accommodate the needs of a particular disability, we have been willing to consider violations of the "make inoperative" prohibition to be justified by public need. As I have already noted above, NHTSA will not institute enforcement proceedings against a business that modifies the seat belt assembly in the 1996 E320 to accommodate the condition you describe as we equate the special needs of a severely obese individual with the needs associated with a disability.

We caution, however, that only necessary modifications should be made. We note that we expect manufacturers to provide complying seat belts that are appropriate for the normal range of occupant sizes, including large persons. Mercedes Benz appears to do this, as it provides a (presumably complying) special order 12-inch longer belt for large persons. We recognize that a severely obese individual is outside the normal range of occupant sizes. Finally, if the vehicle is sold, we urge the owner to advise the purchaser that the vehicle has been modified and consider reinstalling the removed safety equipment.

We do not believe that the installation of an extended-length seat belt assembly in the 1998 S420V Mercedes-Benz is justified by public need as there is no indication that the assembly is needed to accommodate a disability. It appears that the owner is requesting the installation of the extended length seat belt merely for personal convenience-so that he may more readily reach the telephone while seated in the back seat of the car. We would not, therefore, view the installation of an extended-length seat belt assembly in the 1998 S420V Mercedes-Benz as merely a technical violation of the make inoperative prohibition, justified by public need. We suggest that the customer consider having the phone relocated so he can more readily reach it with the rear seat belt secured.

If you have other questions or need some additional information, please contact Nicole Fradette of my staff at this address or by phone at (202) 366-2992.

Dear Mr. Smith:

This is in response to your letter in which you asked whether you are required to conduct impact crash tests as a prerequisite to complying with federal safety requirements. I apologize for the delay in my response. You explain that you modify minivans and full-size vans, both before and after the first retail sale, to accommodate persons with disabilities. The modifications you perform typically involve installing wheelchair lift mechanisms in full-size vans and wheelchair ramp assemblies in lowered floor minivans. You explain that you install various combinations of equipment acquired from a large number of manufacturers and suppliers in your modifications. You explain that you rely on an assortment of impact crash test data, other testing, and engineering analysis in determining whether the vehicle complies with the safety standards. You state that you believe you have exercised due care with respect to these determinations and compliance with all the applicable safety standards. In light of these circumstances, you have asked whether you are required to conduct multiple crash tests. As discussed below, Access Wheels is required to assure that each of the vehicles it manufactures complies with all applicable safety standards, but it is not required to conduct crash tests of any of its vehicles to certify compliance with these standards.

We would like to begin by explaining that the National Highway Traffic Safety Administration (NHTSA) is authorized to issue Federal motor vehicle safety standards that set performance requirements for new motor vehicles and items of motor vehicle equipment. Manufacturers are required to certify that their products conform to our safety standards before they can be offered for sale. Federal law prohibits any person from manufacturing, introducing into interstate commerce, selling, or importing any new motor vehicle or item of motor vehicle equipment unless the vehicle or equipment item conforms to all applicable safety standards. NHTSA, however, does not approve motor vehicles or motor vehicle equipment items, nor does the agency endorse any commercial products or their vendors. Instead, the motor vehicle safety statutes, found in Chapter 301 of Title 49, U.S. Code, establish a self-certification process under which each manufacturer must certify that its products meet all applicable safety standards.

Each of the safety standards specifies performance requirements. Dynamic tests are prescribed under some of the standards, such as Standard No. 208, Occupant Crash Protection, and Standard No. 301, Fuel System Integrity. However, the agency does not require a manufacturer to test its products only in the manner specified in the safety standards. A manufacturer may choose any means of evaluating a vehicle or equipment item to determine whether it complies with the requirements of an applicable standard, provided that the manufacturer assures that the vehicle or equipment item will comply with the standard when tested by NHTSA.

According to 49 U.S.C. 30115, a person may not certify a vehicle as complying with all applicable safety standards "if, in exercising reasonable care, the person had reason to know the certification is false or misleading in a material respect." NHTSA has long said that it is unable to judge what efforts would constitute "reasonable care" in advance of the actual circumstance in which a noncompliance occurs. What constitutes "reasonable care" in a particular case depends on many factors, including such things as the limitations of current technology, the availability of test equipment, the size of the manufacturer, and above all, the diligence exercised by the manufacturer.

Since some of your modifications occur after the first sale of the vehicle to a consumer, you should also be aware of the statutory prohibition against making inoperative any device or element of design installed on or in a motor vehicle in compliance with an applicable standard. After the first sale of the vehicle, manufacturers, distributors, dealers, and repair businesses are prohibited from "knowingly making inoperative" any device or element of design installed on or in a motor vehicle in compliance with an applicable standard. In general, the "make inoperative" prohibition (49 U.S.C. 30122) requires businesses which modify motor vehicles to ensure that they do not remove, disconnect, or degrade the performance of safety equipment installed in compliance with an applicable standard. Violations of this prohibition are punishable by civil penalties of up to $1,100 per violation.

If you have any further questions regarding vehicle certification requirements or the safety standards, please contact Ms. Nicole Fradette of my staff at 202-366-2992.

Sincerely,
Frank Seales, Jr.

Director, Automotive Safety Office

Dear Mr. Camp:

This is in reply to your letter of May 28, 1998, asking that we concur in your conclusion that Ford's "Auto Low Beam" feature complies with Federal Motor Vehicle Safety Standard No. 108.

The feature is intended for a vehicle equipped with a two-headlamp system. If the upper beam of one of the headlamps fails, the feature activates the lower beam of that headlamp and notifies the driver.

You point out that paragraph S5.5.9 of Standard No. 108 requires that:

"[t]he wiring harness . . . of each headlamp assembly shall be designed so that only those light sources intended for meeting lower beam photometrics are energized when the beam selector switch is in the lower beam position, and that only those light sources intended for meeting upper beam photometrics are energized when the beam selector switch is in the upper beam position."

You are concerned that S5.5.9 might not allow Ford to manufacture vehicles with the "Auto Low Beam" because the feature would energize a lower beam light source when the beam selector switch is in the upper beam position.

When an upper beam fails, the headlamp system would not meet S5.5.9. It is only when this type of failure occurs that the Auto Low Beam feature activates the lower beam. However, we do not view S5.5.9 as applying to a failure condition.

A supplementary lighting feature such as the Auto Low Beam is subject to the prohibition of S5.1.3 that it not impair the effectiveness of lighting equipment required by the standard. Although there will be an imbalance of headlamp beams when the Auto Low Beam operates, we do not believe that the automatic operation of the lower beam will impair the effectiveness of the upper beam. The Auto Low Beam provides an alternative headlighting system that will function until the safety performance of the original headlamp system can be restored.

In summary, the Auto Low Beam system is permissible as original equipment under Standard No. 108.

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

Sincerely,
Frank Seales, Jr.
