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.

ATTACHMT: ATTACHED TO LETTER DATED 11-24-92 FROM SHAFI J. KEISLER TO PAUL J. RICE (OCC 8069)

TEXT: This responds to your letter of November 24, 1992, with respect to the manufacture of a replacement taillamp lens for the 1966-67 Dodge Charger. You ask for "all safety standards information pertinent to the manufacture of this replacement lens", and inform us that you "will use only "current DOT and SAE safety approved material to build this item."

As Taylor Vinson explained to you, Federal Motor Vehicle Safety Standard No. 108 Lamps, Reflective Devices and Associated Equipment was amended effective January 1, 1972, to apply to replacement lighting equipment for motor vehicles manufactured on and after that date (the standard had previously applied only to original equipment on passenger cars manufactured on and after January 1, 1969). This means that replacement taillamps designed specifically for the 1966-67 Dodge Charger have never been covered by a Federal motor vehicle safety standard.

Paragraph S5.1.2 of Standard No. 108 does require that plastic materials used for optical parts such as lenses conform to SAE Recommended Practice J576c, May 1970, with certain exceptions. Although this could be construed as requiring compliance of plastics used in any replacement taillamp lens, we do not interpret this as mandating compliance of plastic materials for a lens in a replacement lamp that is itself not subject to Standard No. 108. However, S5.1.2 is the Federal requirement that you would be obliged to meet were you manufacturing new or replacement taillamp lenses for contemporary motor vehicles. I enclose a copy of S5.1.2 and J576c for your information.

We appreciate your desire to meet current safety requirements.

TEXT: Dear Mr. Womac:

The Chief Counsel of the Specialty Equipment Manufacturers Association (SEMA) reviewed all regulations covering wheel covers and suggested that we contact Mr. Truman Vincent. We explained our situation to Mr. Vincent who in turn, suggested that we addre ss our request to your attention.

We are a manufacturer of Aluminum Wheel Covers. They are a standard type and do not have any protrusions (e.g., spinners, etc.). With the assistance of the Chief Counsel at SEMA, the current regulations were reviewed and it was determined that our Alum inum Wheel Covers are similar in design to the Steel and ABS plastic type and are not covered by any regulations, except for # 211 which prohibits protruding objects such as spinners, etc. Our wheel covers do not have any protruding objects.

At the current time, we are the only manufacturers of Aluminum Wheel Covers. Because they are made of a different material from the current steel and ABS models, a major retailer has asked us to confirm that aluminum, like the ABS and Steel wheel covers, do not violate any federal safety standards. Considering information from our SEMA counsel, and Mr. Truman Vincent, we do indeed not violate any federal safety standards. However, the major retailer (and possibly others) has requested a confirmation i n writing from the Department of Transportation. We would appreciate a statement from you with wording to this effect to present to the retailer.

Thank you for your assistance. We would appreciate hearing from you quickly. If desired, you may fax your response to the phone listed below.

Lawrence F. Henneberger, Esq. Arent, Fox, Kintner, Plotkin & Kahn Washington Square 1050 Connecticut Avenue, N.W. Washington, D.C. 20036-5339

Thank you for your letter of September 16, 1985, concerning the applicability of the requirement in Federal Motor Vehicle Safety Standard No. 108 for the installation of center high-mounted stop lamps (CHMSL's) to passenger cars manufactured before September 1, 1985. You also asked about the applicability of the CHMSL performance requirements to CHMSL's sold as aftermarket equipment for cars manufactured before that date. I hope the following discussion answers your questions.

You are correct in stating that there is no requirement in Standard No. 108 for installing CHMSL's on new cars manufactured before September 1, 1985. The installation requirement applies only to cars manufactured on or after that date. (48 FR 48235, October 13, 1984.) The only requirements regarding CHMSL's and pre-September 1, 1985 cars are that if a manufacturer voluntarily installs a CHMSL on a car manufactured on or after August 1, 1984, and before September 1, 1985, the installation must be performed in accordance with criteria concerning the location of the CHMSL, and reflections from it. (49 FR 34488, August 31, 1984.)

As to aftermarket CHMSL's for cars manufactured before September 1, 1985, the applicability depends on whether or not the CHMSL is intended to be installed as a replacement for an original equipment CHMSL that was voluntarily installed on a car that was manufactured on or after August 1, 1984, but before September 1, 1985. If the aftermarket CHMSL is intended to be installed in the interior of such a car, then the manufacturer of the CHMSL must comply with the requirement in S3.1.8.4 concerning minimization of reflections. If the CHMSL is intended to be installed on other pre-September 1, 1985 cars, its manufacturer is not subject to any Standard No. 108 requirements for CHMSL's. However, the agency encourages manufacturers of any aftermarket CHMSL to conform as closely as possible to all criteria in the standard for original equipment CHMSL's. We believe that standardization of rear signals minimizes the possibility of creating confusion to following drivers in situations where immediate action is essential to avoid a rear end collision. Further, aftermarket CHMSL's for those other pre-September 1, 1985 cars would be regulated by the applicable law of the State in which they are operated.

I hope this information is of assistance to you. If you have further questions, please let me know.

Dear Mr. Miller:

As we discussed by telephone, I am requesting that you confirm that Federal Motor Vehicle Safety Standard 108, as it relates to the requirement for installation of a single center, high-mounted stoplamp on passenger cars, does not apply to passenger cars manufactured prior to September 1, 1985, and therefore does not apply to aftermarket center high-mounted stoplamps produced for applications on passenger cars manufactured prior to September 1, 1985.

An expedited response will be very much appreciated.

TEXT: Thank you for your letter of December 22, 1969, to the National Commission on Product Safety, which was referred to this Bureau for further reply. We have noted the Commission's response to you of December 29, 1969.

A review of our files has failed to produce any specific data relevant to the exact nature of the case you have cited. This is attributable to the fact that the accident investigation methodology on which we depend does not break out data in that particular category.

We would like to advise, however, that Federal rule making sections do address door latch releases, or handles, in a different aspect. We are particularly concerned over configurations of door handles which incorporate sharp features or which tend to protrade excessively, as those types of handles increases the likelihood of the door opening as a result of contact by the body of an occupant during a crash situation. Moreover, if they contain sharp features, they can contribute to increased injury levels resulting from occupant impact when the door remains closed.

I regret we are unable to be more responsive to your inquiry. Thank you for writing.

We are in receipt of your letter of December 22, 1969.

As you may know, Congress created this Commission to develop the means to protect the consumer from unreasonably hazardous products used in and around the American household. The scope of inquiry is limited, however, to those products not now the subject of regulations prescribed under existing Federal statutes. These laws are enumerated in Section 6 of Public Law 90-146 (81 Stat. 466).

As your correspondence concerns motor vehicles, it would best be considered by the Department of Transportation. That agency is responsible for the administration of the National Traffic and Motor Vehicle Safety Act of 1966 (15 U.S.C. 1381 et seq.). Accordingly, I am directing your correspondence to the Department of Transportation and have asked that they reply directly to you with a copy to this Commission.

TITLE: FMVSS INTERPRETATION

TEXT: This is in response to your request for an opinion on the applicability of Federal Motor Vehicle Safety Standard 205 to a road grader intended for use in highway construction.

The National Highway Traffic Safety Administration issues safety standards for "motor vehicles." Therefore, our regulations apply to a vehicle and its manufacturer only if the vehicle qualifies as a motor vehicle under the provisions of the National Traffic and Motor Vehicle Safety Act of 1966. Section 102(3) of the Act defines motor vehicle as:

any vehicle driven or drawn by mechanical power manufactured primarily for use on the public streets, roads, and highways, except any vehicle operated exclusively on a rail or rails.

Thus, a motor vehicle is a vehicle which the manufacturer expects will use public highways as part of its intended function.

Tracked and other vehicles incapable of highway travel are not motor vehicles. In addition, vehicles intended and sold solely for off-road use (e.g. aircraft runway vehicles and underground mining vehicles) are not considered vehicles even if operationally capable of highway travel. They would, however, be considered motor vehicles if the manufacturer knew that a substantial proportion of his customers actually would use them on the highway.

Just as clearly, vehicles which use the highway on a necessary and recurring basis to move between work sites are motor vehicles. The primary function of some vehicles is of a mobile, work performing nature and as such their manufacturer comtemplates a primary use of the highway. Mobile cranes, drill rigs, and towed equipment such as chippers and pull-type street sweepers are examples in this area. Even if the equipment uses highways infrequently, it is considered a motor vehicle. An exception to this is that occasional use of the highway in the immediate periphery of the work site, as is the case with some farm and construction equipment, would not by itself case a finding that the vehicle is a motor vehicle. The motor vehicles described above generally qualify as trucks or trailers. As such they are subject to several of the motor vehicle safety standards, and the manufacturer must comply with other regulations in Chapter V of Title 49, code of Federal Regulations.

There are some vehicles which are excepted from the motor vehicle classification despite their use of the highway. Highway maintenance and construction equipment, lane stripers, self-propelled asphalt pavers, and other vehicles whose maximum speed does not exceed 20 miles per hour and whose abnormal configuration distinguishes them from the traffic flow are not considered motor vehicles. This would appear to include road graders whose maximum speed does not exceed 20 miles per hour, if intended for use in highway construction.

From these guidelines you should be able to determine whether a piece of equipment qualifies as a motor vehicle. Please write again if you are unable to make this determination.

Yours truly,

ATTACH.

TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of December 2, 1981, to Dr. Robert L. Henderson of this agency asking for an opinion regarding the legality of a warning system devised by your client, David Stepkin.

Mr. Stepkin's system "flashes the rear brake lights continuously when either brake is applied on a motorcycle." With respect to Federal regulation of motorcycle lighting systems, I refer you to 49 CFR 571.108, Motor Vehicle Safety Standard No. 108, Lamps, Reflective Devices and Associated Equipment, a copy of which is enclosed. Paragraph S4.6(b) in essence requires that brake lamps (or stop lamps as we call them) be steady burning. This requirement would appear to preclude use of your system.

In addition, the substitution of a flashing signal for the steady one to which the public is accustomed might create confusion, thereby impairing the effectiveness of the stop lamp. You will note also that paragraph S4.1.3 prohibits the installation of motor vehicle equipment that impairs effectiveness of required lighting equipment.

Re: Motorcycle-Pulsating and/or Modulating Rear Lights

Dear Dr. Henderson:

I am an attorney who practices in the State of New York and I represent the interests of one, David Stepkin. Mr. Stepkin has devised a warning system which basically flashes the rear brake lights continuously when either brake is applied on a motorcycle. Of course, the purpose of the item is to create rear visability and therefore to prevent the driver of another vehicle travelling behind a motorcycle, from striking the motorcycle due to poor visability.

I am sure you are aware of the fact that motorcyclists are one of the highest prospective candidates for injuries on our roads. Mr. Stepkin, and I as his attorney, feel that this particular item would certainly help to reduce that statistic.

The item in question is a small unit which is attached by splicing the wire between the brake light switch and the rear brake light. The unit is then attached and is ready for operation. Mr. Stepkin, of course, considered attaching the unit to the rear of the bike but has found that this approach is impractical since many bikes will not accommodate an additional auxilliary light. Experience has shown that this is the most effective and practical method. It also, of course, saves energy because no additional lights are needed.

It has come to our attention that there may be certain restrictions in the use of these particular lights. However, we feel that this particular mechanism should not be in conflict with any such regulations because the filament of the bulb is always on.

I am not aware of any specific regulation outlawing such items on the Federal level and certainly, we have been able to ascertain that no such regulation outlawing such lights exists on the State level.

Therefore, I would appreciate it if you would take the time to drop us a short letter advising us whether any regulations concerning this particular item exist and, if you have a copy of those regulations, we would appreicate receiving same. If you feel that the matter should be handled by another department, please advise and we will forward it promptly.

I wish to thank you in advance for your time and courtesy in this matter.

Mr. Ronald P. Jones
Director of Transportation and Maintenance
Highlands Christian Academy
501 N.E. 48th Street
Pompano Beach, FL 33064-9854

Dear Mr. Jones:

This responds to your January 7, 1999, letter requesting an interpretation regarding the use of your 15-passenger van to transport, for school-related activities, students in kindergarten through the twelfth grade. Your letter states: "In speaking with your office, I was told that private schools fall under federal government rules, not state." For purposes of the regulations that govern the use of your vehicles, this statement is incorrect. In general, State law, not laws administered by the National Highway Traffic Safety Administration (NHTSA), regulates vehicle usage.

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."

In general, NHTSA's safety standards directly regulate the manufacture and sale of new motor vehicles, not their use. Each State has the authority to set its own standards regarding the use of motor vehicles, including school buses. You should check Florida law to see if State law may prohibit your private school from using the van to transport students. For information on Florida's requirements, you may contact Florida's State Director of Pupil Transportation:

Mr. Charles Hood, Director, School Transportation
Florida Department of Education
325 W. Gaines St. #824
Tallahassee, FL 32399-0400
Telephone: (850) 487-8608

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 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." 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.
