NHTSA Interpretation File Search
Overview
NHTSA's Chief Counsel interprets the statutes that the agency administers and the standards and regulations that it issues. Members of the public may submit requests for interpretation, and the Chief Counsel will respond with a letter of interpretation. These interpretation letters look at the particular facts presented in the question and explain the agency’s opinion on how the law applies given those facts. These letters of interpretation are guidance documents. They do not have the force and effect of law and are not meant to bind the public in any way. They are intended only to provide information to the public regarding existing requirements under the law or agency policies.
Understanding NHTSA’s Online Interpretation Files
NHTSA makes its letters of interpretation available to the public on this webpage.
An interpretation letter represents the opinion of the Chief Counsel based on the facts of individual cases at the time the letter was written. While these letters may be helpful in determining how the agency might answer a question that another person has if that question is similar to a previously considered question, do not assume that a prior interpretation will necessarily apply to your situation.
- Your facts may be sufficiently different from those presented in prior interpretations, such that the agency's answer to you might be different from the answer in the prior interpretation letter;
- Your situation may be completely new to the agency and not addressed in an existing interpretation letter;
- The agency's safety standards or regulations may have changed since the prior interpretation letter was written so that the agency's prior interpretation no longer applies; or
- Some combination of the above, or other, factors.

ID: nht90-4.76OpenTYPE: Interpretation-NHTSA DATE: December 6, 1990 FROM: Paul Jackson Rice -- Chief Counsel, NHTSA; Signature by S.P.W. TO: Erika Z. Jones -- Mayer, Brown, & Platt TITLE: None ATTACHMT: Attached to letter dated 9-18-90 to S.P. Wood from E.Z. Jones (OCC 5222) TEXT: This responds to your letter requesting a confirmation of your telephone conversation with Mr. Stephen Wood of my staff. In that conversation, he informally stated that the attached letter dated January 5, 1990 from Fidelity Tire Manufacturing company c ontained the information necessary to comply with the notification requirements in S5.1 of Federal Motor Vehicle Safety Standard 119 (49 CFR 571.119) for tires and rims not listed in the publication of a specified tire and rim association. This letter c onfirms that Fidelity's letter would satisfy the requirements of section S5.1. Section S5.1 requires that a listing of the rims which may be used with each tire produced by a manufacturer be provided to the public. The purpose of this requirement is to ensure that the tire will be mounted only on appropriate rims and that the tire will be mounted on vehicles where its load-carrying capacity will be adequate. That section gives manufacturers the option of using the data provided for the tire size and corresponding rims published in certain standardization organization yearbooks o r listing the appropriate information "in a document furnished to dealers of the manufacturer's tires, to any person upon request, and in duplicate to (NHTSA)." Fidelity's letter which includes the appropriate dimensional and load-carrying data for the tire and rim appears to satisfy this requirement. I hope this explanation is helpful. Please contact Mr. Marvin Shaw of my staff at (202) 366-2992 if you have any further questions. |

TO: Takahiro Maeda -- Assistant to the Vice President, Engineering Division, Yamaha Motor Corporation, U.S.A. TITLE: None ATTACHMT: Attached to letter dated 9-28-90 to Office of Chief Counsel, NHTSA from Takahiro Maeda (OCC 5275) TEXT: This is in reply to your letter of September 28, 1990, requesting an interpretation of Motor Vehicle Safety Standard No. 108. Table IV of the standard establishes a minimum "edge to edge separation distance" between turn signal lamps and tail or stop lamps installed on motorcycles. You have asked whether the edge in question is the outer edge of the lamp assembly itself, or th e edge of the reflector in the lamp. The minimum edge to edge separation distance is measured from the edge of the illuminated surface of one lamp to another, that is to say, from the edge of the effective projected luminous area of one lens to the edge of the effective projected luminous a rea of the other. It is unclear from the drawing you enclosed of the "tail/brake lamp" whether the edge of its effective projected luminous area of the lens is at the edge of the reflector, or at the edge of the lamp (as appears to be the case with the "turn signal"). If the former, the distance is measured between the edge of the tail/stop lamp reflector to the edge of the turn signal lamp assembly as you have initially indicated. |

BRAKE ANTI-SQUEEK APPLICATION INSTRUCTIONS STEP 1 : DISASSEMBLY A : Remove pads from caliper assembly. B : Sand pad surface using a light to medium sand paper or emery cloth. This will remove the glaze (on used pads). STEP 2 : CLEANING A : Spray (clean) pad surface liberally with brake cleaner. This removes all contaminants from the pad surface. Let dry completely, approximately one minute. STEP 3 : BRAKE ANTI-SQUEEK APPLICATION A : Heat metal backing plate until lining is hot to open pores in the lining. Soak pads in brake anti-squeek for 10 minutes face down to allow solution to penetrate the pads. Note: Metal backing plate must be heated up to promote faster drying. STEP 4 : REASSEMBLY & INSTALLATION When pad surfaces are compltely dry, assemble and reinstate brake assembly. STEP 5 : TESTING THE BRAKES It should be noted that brakes will GRAB & GROAN tremendously during the first two or three stops. This is normal. USE HUSKY BRAKE ANTI-SQUEEK, EVERYTIME YOU DO A BRAKE JOB. Subject: "Husky Brake Anti-squeek (HBAS)" "cure for noisy, nervous brakes" Thank you for stopping at our booth. The Del Mar manufacturing Co. started business in July 1972 with idea to manufacture and distribute the finest line of automotive chemicals and tire sealing products available at very competative prices. Now after 18 years in business we have reached th is goal of having the highest quality in products available throughout the country for the automobile, bicycle and motorcycle industries. Our products include tire sealers for almost all kinds of tires, brake anti-squeek for disc or regular brakes, D-gu m and Saf-T-Dip: a carburetor parts cleaner and fiberglass metal cleaner and polish. We welcome your orders and look forward to doing business with you. We have nationwide W.D program for our very unique product "HUSKY BRAKE ANTI-SQUEEK". We have manufacturing representatives in all states except east coast and south eastern states. Unlike many other jelly type products which are applied to the back of the plate, HBAS is applied directly on the pad surface which will stop BRAKE SQUEEKING and will produce a surface that gives better braking. The following are unique features of HBAS: * Quiets noisy brakes. * Will stop brake squeaking and eliminate pad squeal. * Produce a surface that gives better braking. * Recommended for use on old or new pads, either metallic, semi-metallic, or organic or non-asbestos organic. Here is some suggested approach that shows you why you should use HUSKY BRAKE ANTI-SQUEEK. 1. 87% of all brake job "comebacks" are squeek related. 2. Husky brake anti-squeek should be applied to all brake jobs as "insurance" against squeek comebacks. 3. One can of HBAS will treat 8-10 brake jobs making it a very in- expensive item to the mechanic, less than $0.50 per brake job. (average brake job - $185.00). This product has been accepted by a great number of new and used car dealers and many big name chains specializing in brake jobs throughout the unites states. We invite you to try this effective solution to a particularly irritating source of noise poll ution. You will be amazed to see the results of your brakes after HBAS application. This product has been endorsed by top two undercar distributors, TRUSTAR and CYGNUS for their members, private label under their name. Thank you very much for your time. Please don't hesitate to call us for any question you may have. BRAKE SQUEAKS DRIVING YOU NUTS !!! Nationally 28% of the brake jobs done come back, of which 87.0% are from squeaks. The reason is because of lack of time, training and competitive cost of the brake job. A large part of the squeaks are caused from the rotor and brake pad vibration. Squeaks are vibrations. To help you understand more fully, think of the rotor being trued up by grinding away the rotor surface from the center to the outside edge of the rotor. By doing so, even on a fine cut, you leave grooves very much like a phonograph record has. When you install the brake pads face surface to the rotor with groves, the brake pad is softer than the rotor and the rotor cuts grooves in the brake pad. When the rotor turns, the grooves and the brake pads try to follow the rotor grooves to the outsid e edge of the rotor, very much like the record player arm and needle follows the grooves in the phonograph record. We call this record effect, causing a squeak. With the brake pad it can only travel so far and then snaps back and starts all over again until the rotor and brake pad wear together to a smooth working surface. It takes about 3000 to 5000 miles for this to happen. This is by far the largest cause of squeaks in the brakes today. To help correct this , there is a product called "HUSKY", it is an anti- squeek compound, made by Del Mar Manufacturing Company. It is a compound that is applied to the face surface of the brake pad which soaks into the padding material and has graphite in it to help the pad to slip and not drag on the rotor, therefore eliminating the pad and rotor wearing together to cause a sque ak. For a few cents per brake job, you can be assured that your customer's brake job will not come back with that all too frequent squeak that cost you time and money and most of all your customers trust you did the job right the first time.

Jones to Clive Van Orden (OCC 5733) TEXT: I am indebted to Congressman Ben Blaz for your name and area of responsibility. I am enclosing some correspondence that will give you some details of our problem. In a nut shell, we want the Federal Government to enforce the FMVSS and FMCSR regulation in the CNMI or wave them completely until such time they are ready and able to im plement and enforce them. As you may know, there are no pollution problems on Saipan, Tinian or Rota and the speed limit is 25 in most places, 35 maximum. I doubt that it is advantageous to the CNMI residents to pay the extra 3 or $400 for automobile EPA and Safety features that are not needed. Governor Guerrero has taken a position that these regulations are not needed or desired. I agree with that position 100%. But, I have bigger problems with the regulations being, so called, applicable and not monitored or enforced. |

Nakama -- Rule Making Attorney, United States Department of Transportation TITLE: None ATTACHMT: Attached to letter dated 3-14-91 from Paul Jackson Rice to Loren Thomson (A37; Std. 205; VSA 108(a)(2)(A)) TEXT: I represent the Glass Specialty Companies. They, as well as others in the glass repair and replacement industry have concerns with the types of repair being afforded by some members of the industry and with the replacement of original equipment, automob ile glass, with substandard glass. Edward H. Barnes, the president of Glass Specialty with whom you have talked, indicates to me that you've indicated that the Federal Motor Vehicle Standard, No. 205, is not specific upon standards with respect to the repair or replacement of automobile g lass. The only standard being that the repair or replacement must not leave the vehicle, "inoperable," or render it so. Our position is that if a windshield or a side glass is likely to shatter or distort the vision of an operator, the vehicle is indeed "inoperable." We would respectfully request an interpretive letter from your department of what the term "render inoperable" means in safety standard no. 205 as regards a chipped, cracked, or broken windshield. If you have any questions on the matter, please direct them to me. |

ID: nht90-4.81OpenTYPE: Interpretation-NHTSA DATE: December 13, 1990 FROM: Paul Jackson Rice -- Chief Counsel, NHTSA TO: Danny Pugh -- Engineering Manager, Utilimaster Corporation TITLE: None ATTACHMT: Attached to letter dated 9-13-90 to Chief Counsel, NHTSA from Danny Pugh (OCC 5214) TEXT: This responds to your letter seeking an interpretation of Standard No. 208, Occupant Crash Protection (49 CFR S571.208). More specifically, you asked about the requirements for safety belts at the various seating positions in vehicles with a gross vehic le weight rating under 10,000 pounds that you called "van conversions." You first asked whether a "van conversion" would be classified as a passenger car, truck, or multipurpose passenger vehicle. Vehicles commonly called "vans" may be classed in four different vehicle categories (set forth at 49 CFR S571.3) for the purpose s of our safety standards, depending on the configuration of the particular "van." Most cargo vans are classified as "trucks" under our safety standards, because those vehicles are "designed primarily for the transportation of property or special purpos e equipment." Most passenger vans are classified as "multipurpose passenger vehicles," because they do not meet the definition of a "truck" but are constructed on a truck chassis." Those vans that have eleven or more designated seating positions are cl assified as "buses" because they are "designed for carrying more than 10 persons. Finally, one minivan (the Nissan Axxess) was certified by its manufacturer as a "passenger car" because it was "designed for carrying 10 persons or less." Additionally, the National Traffic and Motor Vehicle Safety Act places the responsibility for classifying a particular vehicle in the first instance on the vehicle's manufacturer. For this reason, NHTSA does not approve or endorse any vehicle classifica tion before the manufacturer itself has classified a particular vehicle. NHTSA may reexamine the manufacturer's classification in the course of any enforcement actions. If you are interested in the appropriate classification for a particular van conver sion, we will offer our tentative opinion if you will provide us with detailed information on the van conversion in which you are interested. You next asked on what date safety belts were required in "van conversions," what type of safety belts, and at what locations those belts were required. As explained above, we do not class vehicles as "van conversions" for the purposes of our safety sta ndards. If the vans were classed as passenger cars, passenger cars manufactured on or after January 1, 1968 were required to have lap/shoulder safety belts at the front outboard seating positions and either lap/shoulder or lap-only safety belts at every other seating position in the car. Beginning December 11, 1989, passenger cars were required to have lap/shoulder safety belts at both front and rear outboard seating positions, with either lap/shoulder or lap-only safety belts at every other seating p osition. Since September 1, 1989, all passenger cars are required to be equipped with automatic crash protection for outboard front-seat occupants. Multipurpose passenger vehicles and trucks with a gross vehicle weight rating of 10,000 pounds or less manufactured on or after July 1, 1971 were required to have lap/shoulder safety belts at the front outboard seating positions and either lap/shoulder o r lap-only safety belts at every other seating position in the vehicle. Beginning September 1, 1991, vans classified as multipurpose passenger vehicles or trucks (other than motor homes) must have lap/shoulder belts at both front and rear outboard seati ng positions, with either lap or lap/shoulder belts at all other seating positions. Motor homes manufactured on or after September 1, 1991 will continue to be required to have lap/shoulder belts at front outboard seating positions and either lap/shoulde r or lap-only safety belts at every other seating position. In addition, effective September 1, 1991 vans must meet dynamic crash test injury criteria for the front outboard seating positions. If the vans were classed as buses, buses manufactured on or after July 1, 1971 were required to be equipped with either a lap/shoulder or a lap-only safety belt at the driver's seating position. Beginning September 1, 1991, buses with a gross vehicle we ight rating of 10,000 pounds or less (except school buses) must be equipped, with lap/shoulder belts at all front and rear outboard seating positions, and either lap/shoulder or lap-only safety belts at every other seating position. Also, the agency has proposed extending the automatic crash protection requirements mentioned above to these other vehicle classifications. I hope this information is useful.

ID: nht90-4.82OpenTYPE: Interpretation-NHTSA DATE: December 13, 1990 FROM: Paul Jackson Rice -- Chief Counsel, NHTSA TO: M.J.P. Ravier -- R&D Director, Valeo TITLE: Re Your ref 861 M 90 ATTACHMT: Attached to letter dated 7-13-90 to P.J. Rice from J.P. Ravier and Guy Dorleans (OCC 5304); Also attached to letter dated 7-30-90 to J.P. Ravier from Kathleen Demeter TEXT: This is in further reply to your letter of July 13, 1990, with respect to whether your "Aiming concept for headlamps, Solution 2" is acceptable under paragraph S7.7.5.2 On-vehicle aiming of Federal Motor Vehicle Safety Standard No. 108. Ms. DeMeter of t his Office has previously addressed your request for confidentiality. The headlamp aiming concept consists of a spirit level affixed to the reflector, and has its axis parallel to the longitudinal axis of the vehicle. Correct vertical aim is accomplished by ensuring that the bubble in the spirit level is centered at zero. Correct horizontal aim is ensured through a coaxial screw and nut with markings which align with markings on the vehicle body. The system bears graduations that accord with those imposed by S7.7.5.2. As Valeo was informed when the device was demonstrated to members of this agency on June 29, 1990, the concept is an acceptable vehicle headlamp aiming device under S7.7.5.2. It is designed to meet the vertical aim requirements of S7.7.5.2(a)(1) and the horizontal aim requirements of (a)(2). We are pleased to provide a confirmation in writing. |

ID: nht90-4.83OpenTYPE: Interpretation-NHTSA DATE: December 13, 1990 FROM: Paul Jackson Rice -- Chief Counsel, NHTSA TO: M. Iwase -- General Manager, Technical Administration Department, Koito Mfg. Co. Ltd. TITLE: None ATTACHMT: Attached to letter dated 11-20-90 to Paul Jackson Rice from M. Iwase (OCC 5458) TEXT: This is in response to your letter of November 20, 1990 with respect to "interpretation and/or petition" concerning combination headlighting systems. Koito has asked about the permissibility of two or four lamp headlighting systems in which the upper beam would be provided by integral beam headlamps, and the lower beam by replaceable bulb headlamps. The systems you describe would not be permissible under Standard No. 108, which allows only the three types of headlighting systems that you mention. Integral beam headlighting systems must be comprised of integral beam headlamps which, by definition, a re headlamps other than sealed beam or replaceable bulb headlamps. Replaceable bulb headlighting systems are those that incorporate the standardized replaceable light sources listed in Standard No. 108. We are transmitting your request to the Office of Rulemaking, for consideration as a petition for rulemaking. |
