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: nht81-2.47OpenDATE: 07/14/81 FROM: AUTHOR UNAVAILABLE; F. Berndt; NHTSA TO: Firestone Tire Company TITLE: FMVSS INTERPRETATION TEXT: This responds to your recent letter to Mr. Kratzke of my staff, describing a situation in which a railroad car full of new tires caught on fire. As a result of the damage caused to the tires by the fire, Firestone's quality control staff determined that the tires could no longer be certified as safe for highway use. The railroad company has refused to pay your claim for damage to the tires unless Firestone releases the damaged tires to the railroad company. You stated that the railroad company will either sell the tires through its salvage outlets or use the tires on company vehicles. You ask whether you can rightfully withhold these tires from the railroad company. If Firestone releases the tires and the railroad company sells the tires or uses them on the public roads, both Firestone and the railroad company would violate an express provision of the National Traffic and Motor Vehicle Safety Act of 1966, as amended (15 U.S.C. 1381 et seq.) ("the Safety Act"). Therefore, you can rightfully withhold the tires from the railroad company. Your letter did not indicate whether the damaged tires were tires for passenger cars or tires for motor vehicles other than passenger cars. In either case, the tire manufacturer is required to certify that each tire fully complies with certain marking requirements and with specified performance requirements (resistance to bead unseating, strength, endurance, and high speed performance) of Safety Standard No. 109 in the case of passenger car tires (49 CFR @ 571.109) or of Safety Standard No. 119 for tires other than passenger car tires (49 CFR @ 571.119). This certification is made by the manufacturer by molding the letters "DOT" into the sidewall of the tire. As a result of the damage to this particular shipment of tires, your company has determined that this certification is no longer valid. This determination obligates Firestone to remove the "DOT" symbol from the sidewall of the tires. Without the "DOT" symbol, these tires would clearly not comply with the requirements of either Standard No. 109 or Standard No. 119. Section 108(a)(1)(A) of the Safety Act (15 U.S.C. 1397(a)(1)(A)). provides: No person shall manufacture for sale, sell, or offer for sale, or introduce or deliver for introduction in interstate commerce, or import into the United States, any . . . item of motor vehicle equipment manufactured on or after the date any applicable Federal motor vehicle safety standard takes effect under this title unless it is in conformity with such standard . . . . Firestone would violate this prohibition if it were to deliver tires to the railroad company which were not certified as complying with the appropriate safety standard. The railroad company would violate this prohibition if it sold or offered to sell uncertified tires, or if uncertified tires were used by the company on the public roads (introduction in interstate commerce). Section 109 of the Safety Act (15 U.S.C. 1398) specifies penalties of up to $ 1000 for each violation of section 108, and each tire delivered by Firestone or sold or used by the railroad company would constitute a separate violation of section 108. Section 109 specifies that the maximum civil penalty which can be imposed for a series of related violations, which this would be, is $ 800,000 for each violator. You indicated that Firestone would not release the damaged tires for use in any case, because of the potential safety hazard. I hope that this response reinforces that position. Should you need any further information on this matter, please do not hesitate to contact me. Please show this letter to the interested railroad company so that it will realize the serious nature of its contemplated actions. SINCERELY, Firestone TIRE COMPANY June 24, 1981 The National Highway Safety Administration Office of Chief Counsel Attention: Steven Kratzke Dear Mr. Kratzke: Pursuant to our phone conversation this morning, we would appreciate hearing from you and the National Highway Safety Administration as to the disposition to be made on tires which have been exposed to fire while in transit. We experience approximately five of these situations per year and recently we've experienced an incident where the carrier is demanding that we release to them the salvage. In this particular incident, the carload of 1,596 tires was shipped from our Decatur, Illinois Plant back in June of 1979. Enroute the carrier noticed a missing hasp and ordered the car confined to its repair track until a new hasp could be affixed to the car. In the process of welding the hasp on to the car a small fire started which the carrier's employees quickly extinguished. After a break for lunch and the subsequent return from lunch the car was again found ablaze. The car was again extinguished by both the railroad's employees and the local fire department. Our Quality Control people inspected the tires and found them to be in a condition not suitable for highway use. The railroad retained outside experts in this area and our company likewise retained experts to evaluate the condition of these tires to confirm basically what our Quality Control people originally decided. Both these outside firms cannot guarantee the safety of these tires. The railroad has refused to pay our claim unless we release these tires to them to be salvaged through their salvage outlets to the public or for use on their own company vehicles. We find this railroad's request in total disregard of public safety. We would appreciate your confirming in writing basically how the National Highway Safety Administration feels about this and whether or not a manufacturer of tires, such as Firestone is correct in wanting to scrap these tires in such a manner that they are never used on the highway. We are confirming at this time that we have no intentions of releasing these tires to this particular railroad but would appreciate your decision as to whether or not we can rightfully withhold these tires from the railroad for their salvaging, which in the end will hopefully produce a settlement from the railroad for the value of these tires which they destroyed. Thank you. C. L. BIDDLE SUPERVISOR OF CLAIMS GENERAL TRANSPORTATION DEPARTMENT |

ID: nht81-2.48OpenDATE: 07/16/81 FROM: AUTHOR UNAVAILABLE; F. Berndt; NHTSA TO: CSMPCO Corporation TITLE: FMVSS INTERPRETATION TEXT: Thank you for your letter of March 3, 1981, providing additional information about the "Downshift Warning System Kit." After reviewing this information and the points you make concerning Federal Motor Vehicle Safety Standard No. 108, we wish to point out that the pertinent provisions of this standard are S4.1.3 and S4.5.4. For your information, a copy of Standard 108 is enclosed. You will note that S4.1.3 provides that: "No additional lamp, reflective device or other motor vehicle equipment shall be installed that impairs the effectiveness of lighting equipment required by the standard." Further, you will note that S4.5.4 provides that: "The stop lamps on each vehicle shall be activated upon application of the service brakes." This means that your system must not impair the effectiveness of the stop lamps that are original equipment on the vehicle, and that any application of the service brakes that does not activate the stop lamps would be inconsistent with Federal requirements. As we have made no formal study of your system, you will have to determine whether a vehicle on which it is installed would meet Standard No. 108. Also enclosed for your information is a copy of the National Traffic and Motor Vehicle Safety Act. Section 108(a)(2)(A) is interpreted to mean that the installation of your system on a used vehicle by a person other than its owner must not render inoperative in whole or in part, the stop lamp system. However, the prohibitions of the Act and the standard do not cover sale of your system as an aftermarket device nor its installation solely by the vehicle owner. Use of it is subject to State regulation. We would also like to call your attention to the agency's study: "Field Test Evaluation of Rear Lighting Deceleration Signals - Analytical and Experimental Studies (1979)" (DOT HS 805 061). We urge that you obtain a copy of this report and consider it carefully with regard to your system. You may obtain a copy by writing to the National Technical Information Service, Springfield, Virginia 22161. The agency has tentatively decided that a single high-mounted auxiliary stop lamp is the most effective way of preventing rear end collisions and has proposed that such be made available both as original equipment and in the aftermarket. I enclose a copy of the proposal for your consideration. ENCLS. CSMPCO CORPORATION March 3, 1981 Frank Berndt, Chief Counsel Office of Chief Counsel, NOA-30 National Highway Traffic Safety Administration Dear Mr. Berndt: Compliance status of the "Chicoine Downshift Warning System Kit" with Federal Motor Vehicle Safety Standards Nos. 105, 108 and 121. In your letter of November 14, 1980 you informed me: * Your review of standard Nos. 105 and 121 show that installation of the kit on a vehicle would not render it noncompliant with them. * I regard to the lighting standard No. 108, you have several questions for me to answer. But first, I wish to inform you that I have added a "Conditioned Availability" ancillary system, to the basic kit (return samples). It is a permissive concept introduced to guard against the main system's abuser by its user(s), whether the attempt(s) is inadvertently or maliciously perpetrated. If you will, please carry the evaluation of compliance to the lighting standard No. 108, using my up-graded system. I have two versions to present of the ancillary system for the compliance evaluation: First version: Vacuum Control/engine intake manifold's high vacuum condition triggers, a normally openned, permissive switch's closing. The switch is wired in series with the gear shift knob switch, the closing of both switches is required for the activation of the brake lights. A vacuum delay valve and a vacuum control valve are added to the ancillary system, to give it a time delay effect that will reduce the system sensitivity to the intake manifold vacuum fast variances. This way an operator can upshift without incurring activation risks of his vehicle brakelights. 1) Delay Valve A delay valve is fitted in the vacuum line between/near the permissive vacuum-operated switch and the present vacuum control valve. The delay valve is an air flow (vacuum) restrictor, it allows unrestricted flow of air one way and impeded flow the other way. It is necessitated for protection continuity in upshift operation. 2) Present vacuum control valve The preset control valve is vacuum operated and is fitted in the vacuum line between/near the delay valve and the intake manifold. The preset vacuum control valve closes when the vacuum drops by 5" hg. below the triggering vacuum setting of the permissive vacuum-operated switch. It is necessitated for protection continuity in upshift operation. Second version: Electronic control/the control device's logic reads the vehicle's deceleration rate and compares it to the manufacturer selected rates (i.e.: 1.5 mph/sec. is acceptable). And as long as the vehicle deceleration rate matches or exceeds the device's set rate, the control device enters and remains into an available operative mode. With the electronic control device in an available operative mode the vehicle's operator can then activate his vehicle's brakelights by using the gearshift switch. Hall Effect Devices or Wire Coils are used with magnets to generate signals of vehicle velocity to the electronic control device. The takeoffs are from the vehicle's drive shaft or the vehicle speedomaster cable. A power transistor that is built-in with the electronic control device, is used instead of the electrical-mechanical relay found in the basic kit. To your first question: "We would like to know if your system prevents the turn signal lamps from flashing, in lamps combining stoplamp and turn signal lamps." The answer is no. My system will not prevent the turn signal lamps from flashing in lamps combining stoplamps and turn signal lamps. First reason) The brake switch is not a controlling component for the turn signal lamps flashing operation(s). Second reason) The kit's relay contact are wired in parallel with the brake pedal stoplamps switch's tabs in other words, the existing switch is simply wirejumped and the kit's relay switch is substituted for the existing brake switch. I have a '78 Fiesta-Sport Model and it has the lamps combining stoplamps and turn signal lamps that your question refers to. Closing of the brake pedal switch does not prevent the turn signal lamps from flashing, nor does the closing to the kit relays contact prevent the turn signal lamps from flashing. I carried the experience in my garage. Reply to your second question and closing request: "We would like clarification whether the system activates the stop lamps by pushing the button alone or whether actual motion of the gear shift lever is also required. If the former, we would appreciate your views on possible abuses) of the system, . . . . " Your second question and closing request convey a message of concern for abuse(s) of the system. That message has influenced my decision to supplement my basic kit with the conditioned availability ancillary system, both versions are automated, beyond operator's control, and work on a permissive concept basis to keep in check main system's abuses. The content in your second question is a good example of conditioned availability -- the motion of the shift lever be reflected as a condition to fulfill for the system operativeness. But I have not selected as a requirement the motion of the shift lever for the system operativeness. I have given consideration to the following points: 1) The gear selection(s) for an upshift or a downshift in vehicle(s) equipped with a manual transmission is left to the operator's discretion and vehicle's demand(s). 2) The traffic flow pattern(s) does very i.e.: A traffic flow pattern may dictate a downshift: * for an acceleration of the vehicle * for a deceleration of the vehicle 3) The cost of retrofitting of the vehicles already on the roads. 4) The selected permissive ancillary systems' operations: * are to be fully automated * are to be controlled by inputs that are relating to the vehicle modal status of acceleration and deceleration. * in case of component(s) failure, the system is to become inoperative, the fail safe concept. 5) The activation of the downshift warning system kit is to remain a manual, conscious operation by the vehicle operator. 6) The language of the vehicles' stoplamps: To the non-lead driver, the following message have become universal standards, for the vehicles moving on relatively flat grade. 1. Stoplights OFF - Brakes OFF - STOP NOT IN Progress 2. Stoplights ON - Brakes ON - STOP IN Progress *3. Stoplights OFF - Brakes ON - STOP IN Progress **4. Stoplights OFF - Brakes OFF - STOP IN Progress * The message applies in cases where the stoplamps system of the lead vehicle is defective (i.e.: burnt stoplamps). ** The message applies in cases where the lead vehicle operator uses the engine brake (downshifts) to come to a stop or a slowdown. I refer to this message as "The Burnt Stoplights Syndrome." Note: Operating a vehicle that has its stoplamps system out of order (i.e.: burnt stoplamps) is inconsiderate of other people's safety and is incomsiderate of one's (operator) own safety as well. The same can be said for the operator(s) that downshift to a stop. I address this "The Burnt Stoplamps Syndrome." The use of the device can help keep in check "The Burnt Stoplamps Syndrome." The device restores safety to the operator(s) that uses the downshift method to stop/slowdown his vehicle. The following driver(s) will share same. 7) The device is not to impair the integrity and effectiveness of lighting equipment that the standard requires. The device is to enhance the integrity and effectiveness of lighting equipment that the standard requires. Downshifting makes use of engine braking energy instead of letting it be wasted. In a world that is energy short, let's make it safe to use that stopping method. I trust that I have satisfactorily answered your questions. Enclosed is a flow-sheet layout copy of the kit's components and wiring, first version adaptation. Gustave J. Chicoine, President CSMPCO Corporation ENC. (Graphics omitted) WIRING DIAGRAM |

ID: nht81-2.49OpenDATE: 07/17/81 FROM: AUTHOR UNAVAILABLE; Frank Berndt; NHTSA TO: Department of Transportation; Michigan TITLE: FMVSR INTERPRETATION TEXT: This responds to your March 30, 1981 letter pertaining to the mounting of an old school bus body on a new chassis. The National Highway Traffic Safety Administration (NHTSA) has stated that such a mounting constitutes the manufacture of a new motor vehicle and must comply with all applicable safety standards in effect at the time of that manufacture. This statement comes from previous agency interpretations of the National Traffic and Motor Vehicle Safety Act and from the rationale underlying the provisions of section 571.7(e) of our regulations. You state that section 571.7(e) applies only to trucks and, accordingly, has no application to school buses. The agency has had a longstanding position that a vehicle combining an old body and new chassis is a new vehicle. This position was developed and applied long before the proposal of section 571.7(e) in May 1975. See, for example, the enclosed 1972 letter of interpretation and the discussion of pre-proposal interpretations in the enclosed copy of the May 1975 proposal. The codification in section 571.7(e) of the agency's position as regards trucks did not alter its simiar position as regards other vehicle types. I am enclosing a 1978 interpretation stating that school buses will be treated under the National Traffic and Motor Vehicle Safety Act in the same fashion as trucks are under section 571.7(e). The reason for this interpretation is the similarity of the practice of manufacturing school buses and trucks on new truck chassis. Accordingly, the agency has applied the same rationale in determining those vehicles, e.g., buses, that are to be considered newly-manufactured. In light of these existing interpretations and in the interest of safety, the agency is retaining its position that vehicles using old bodies and new chassis be treated as newly manufactured vehicles. ENCLS. STATE OF MICHIGAN DEPARTMENT OF EDUCATION March 30, 1981 Roger Tilton, Chief Counsel National Highway Traffic Safety Administration Dear Mr. Tilton: The State of Michigan is in the grips of a financial crisis which is now threatening the children of this State through the local school's inability to provide new school buses to replace those which have reached the end of their life expectancy. New school bus purchases are off by about 75% due to budget constraints which have also reduced the State's assistance to the school district from 68% during the last reimbursement period to an expected 30% for the 80-81 fiscal year. In this State, we turn over 1,900 school buses each year. As a means to provide safe, dependable and economical school bus transportation, the local school districts are contemplating rehabilitation of these older school buses. Rebuilding an old school bus is easy and economically rewarding. However, there are many old school bus bodies (approx. 20% or 350 each year) that would better serve the fleet if they were mounted on new chassis. We, in the State of Michigan, are fully aware of previous interpretation of Part 571.7(e) of the Federal Motor Vehicle Safety Standards which relates to combining new and used components. The interpretations which are printed for all who ask, come from Joan Claybrook's office and from Frank Berndt do not say one shall not put an old school bus body on a new chassis, BUT that when an old school bus body is placed on a new chassis, the entire re-manufactured vehicle must comply with all of the FMVSS's in effect on the date of re-manufacture. The interpretation leads us to Part 571.7(e). The Part 571.7(e) relates to "TRUCKS" and does not address "BUS" or school bus. Since there is "TRUCK" listed in definitions, Part 571.3 and the word "BUS" is also in definitions Part 571.3; we contend that 571.7(e) does not apply to Bus or School Bus since 571.7(e) does not refer to "BUS" in its content. We do not accept the interpretation provided by Joan Claybrook or Frank Berndt. We completely understand that by allowing these used buses manufactured prior to April 1, 1977 to wash out of the system that in a few years the only buses on the road will be those which were manufactured in compliance with 220, 221, & 222. The Part 571.7(e) also tells us that the re-manufactured truck must meet the current FMVSS "unless the engine, transmission, and drive axle(s) (as a minimum) of the assembled vehicle are not new, and at least two of these components were taken from the same vehicle." Therefore, if we in Michigan make these drive line changes we do not have a re-manufactured truck and we can continue to use a pre April 1, 1977 school bus body which still does not meet 220, 221, & 222; while mounted on a post April 1, 1977 chassis. I submit to you that your office, NHTSA, is saying that we may not put a pre April 1, 1977 school bus body on a post April 1, 1977 chassis unless the body is updated to meet the post April 1, 1977 FMVSS 220, 221, & 222, OR instead of updating the body, we may install a used engine, transmission, and rear end in the new chassis; two of those three components must come from the same used vehicle. Your interpretation is illogical and seemingly does not apply where school buses are concerned. We respectfully request a new interpretation keeping in mind that it is President Reagan's philosophy that those Federal Regulations which are non-productive, yet require great expense in order to comply; are Regulations with which we need to deal. The State of Michigan, the State Department of Education, and I personally feel bound to comply with Federal Law; however, we do not feel bound to comply with an interpretation which smacks of pressure from the manufacturers and dealers who are in the business to sell new bodies. We eagerly await your response. Larry Louderback, Safety Specialist Pupil Transportation cc: PHIL O'LEARY - SAFETY & TRAFFIC PROG; MR. WEINHEIMER - MICH. SCH. BD. ASSOC.; MR. TEBBE - UNION CITY SCH.

ID: nht81-2.50OpenDATE: 07/22/81 FROM: AUTHOR UNAVAILABLE; F. Berndt; NHTSA TO: British Standards Institution TITLE: FMVSS INTERPRETATION TEXT: This responds to your letter of June 8, 1981, concerning Standard No. 209, Seat Belt Assemblies. You are correct that my letter of June 1, 1981, on the abrasion test procedure of the standard should have referred to section 5.1(d), instead of to section 5.2(d). You also suggested that in the process of clarifying the standard's abrasion requirements, the agency should consider possible modifications to sections 4.2(e) and (f) of the standard. In the process of reviewing the abrasion test requirements, the agency will also examine those other sections to determine what changes should be made. Finally, you raised the issue of whether the standard, as with other national and international standards, should have a requirement that conditioned webbing must retain a certain percentage of its unconditioned strength and must also meet the minimum strength requirement for unconditioned webbing. The agency is not aware of any data indicating that our current conditioned strength requirements are insufficient. Sincerely, ATTACH. JUNE 8, 1981 F Berndt -- U.S. Department Transportation, National Highway Traffic Administration Dear Mr Berndt Many thanks for your letter dated 1 June 1981 regarding abrasion testing to FMVSS 209. However, should Section 5.2 (d), when it occurs, read 5.1 (d)? I understand your reasoning for the clarification, however, should this be extended to cover Sections 4.2 (e) and 4.2 (f)? In most of the National and International specifications which we test to the strength after conditioning must be above a certain percentage of its unconditioned strength and also above the minimum required strength of the webbing. You are permitting the use of webbing that might, after abrasion, fall below your minimum strength requirement. Do you have any comments on this? I look forward to receiving a prompt reply to the first paragraph. Yours sincerely J E BINGHAM -- SENIOR TEST ENGINEER, MOTOR VEHICLE SAFETY COMPONENTS SECTION, BRITISH STANDARDS INSTITUTION |

ID: nht81-2.6OpenDATE: 03/20/81 FROM: AUTHOR UNAVAILABLE; F. Berndt; NHTSA TO: Boyd, Payne, Gates & Farthing TITLE: FMVSS INTERPRETATION TEXT: MARCH 20, 1981 NOA-30 Mr. Charles E. Payne Boyd, Payne, Gates & Farthing Virginia National Bank Building Suite 1240 One Commercial Place Norfolk, Virginia 23510 Dear Mr. Payne: This responds to your recent letter concerning the problem plaintiffs' lawyers in civil cases have in obtaining certain data from foreign manufacturers of automobiles. Your letter specifically asked if there are any Federal safety standards concerning the crashworthiness of automobile seats. You state that the Department of Transportation informed you by letter that there are no such standards. This is incorrect. Federal Motor Vehicle Safety Standard No. 207, Seating Systems (49 CFR 571.207), specifies performance requirements for vehicle seats in passenger cars and other vehicles. The standard requires passenger seats to be able to withstand forces equal to twenty times the weight of the seat without collapsing. This is a static test in which the force is applied directly to the seat. The standard does not, however, require a dynamic crash test of vehicles to determine seat integrity, such as the tests used by the Insurance Institute for Highway Safety cited in your letter. Under the National Traffic and Motor Vehicle Safety Act, as amended 1974 (15 U.S.C. 1381, et seq.), Toyota Motor Company is required to certify that its vehicles comply with Safety Standard No. 207. I am enclosing a copy of the standard for your information. Please contact Hugh Oates of my office if you require any further information (202-426-2992). Sincerely, Frank Berndt Chief Counsel Enclosure March 5, 1981 Frank Berndt, Esquire Chief Counsel U.S. Department of Transportation 400 7th Street S.W. Washington, D.C. 20590 Dear Mr. Berndt: Congressman Bill Whitehurst forwarded to you my recommendation concerning legislation or regulations aimed at forcing foreign manufacturers of mechanical products imported into this country, to file for record with your agency certain data accessable to private litigants. You sent him a reply letter dated February 18th and he sent me a copy. Your letter was informative and helpful. I would even agree that the regulations that you referred to are of some help. However, I do not think they truly meet the problem. A news release issued by the Department of Transportation reported that foreign imports were notably less safe than their American counterpart automobiles. I also have in my possession in connection with litigation I am now pursuing against Toyota, data from various organizations around the country which data discloses that occupant safety and crashworthiness are of little concern to those who manufacture their cars and ship them into our country from abroad. The same data also diclosed that American manufacturers, on the other hand, have by-in-large, done very well in comparison to the foreign manufacturers in the area of crashworthiness and occupant safety. I believe that most attorneys who practice products liability litigation will agree that the greatest single impetus for improved crashworthiness and occupant safety of American automobiles has been our system of tort liability, and the effectiveness of our courts and plaintiff's counsel in bringing to light defects and unsafe designs in automobiles.
Apparently however, most notably our Japanese friends have by-in-large not been subjected to the same examination by litigation of their design concepts and practices with respect to occupant safety. I for one am convinced, as are a good many of my colleagues at the plaintiff's bar, that part of the reason for this is the substantial difficulty of gaining access to files and records of the foreign manufacturers. This same difficulty was a subject of an in depth investigative reporting effort by "60 Minutes" last year. Perhaps you are aware of it. The problem has not been an inability to gain in personam jurisdiction over the foreign manufacturers. That is the easiest part of it. However, once they are in court, they have proven very adroit at using every conceivable tool to preclude production for examination by plaintiff's experts of such things as design specifications, computer simulation data, and films of crash testing. Their excuses include the language barrier, the transoceanic legistics and communications probIems, as well as the "We are a multi-national corporation with warehouses full of documents, and it is impossible to locate what you want" excuse. I believe that if the Japanese and Germans, whose cars are the principal culprits, were forced by the spector of substantial civil liability quickly and efficiently imposed, they would build their cars with the crashworthiness and occupant protection equal to American cars. I also dare say that if they had to do so, they could not market their cars at a price competitive to American makes. While I appreciate the intent of the regulations you cite which require all automobiles imported to be certified to meet the Department of Transportation safety standard, that program does not appear to have yet begun to prove effective. One reason is that the Department of Transportation safety standards are by no means comprehensive. In particular, with respect to the suit I now have against Toyota, the Department of Transportation has advised me by letter J that there is no safety standard currently in existence with respect to the crashworthiness and design safety of passenger seats. The decedent, whom I epresent, died as a result of his seat collapsing upon moderate rear end impact making it possible for his upper torso, neck and head to be whipsawed, and in turn resulting in a fatal injury to the brain stem. It is with somewhat bitter irony that I refer you to report A-4650.01, dated November 1973, issued by General Environments Corporation and prepared for the Insurance Institute for Highway Safety. That report and others like it cite over and over again that upon moderate impact from the rear, the seats of most of the foreign imports collapsed, exposing the occupant to serious and avoidable risk injury, whereas the same testing done on American makes shows a dramatically lower incidence of seat failure. If I have been misinformed, and if there truly is a Department of Transportation safety standard concerning the crashworthiness of automobile seats, I would appreciate a copy of such standard. Also, if there is such a standard I should like to report that I have serious reason to believe that Toyota automobiles manufactured between 1973 and 1979 do not meet anyones safety standard with respect to the design of their seats, and especially the bucket seats. I appreciate your time and attention to this letter and its intent. Yours very truly, BOYD, PAYND, GATES & FARTHING Charles E. Payne CEP:wjb cc: Mr. James Kelly |

ID: nht81-2.7OpenDATE: 03/20/81 FROM: AUTHOR UNAVAILABLE; F. Berndt; NHTSA TO: W. Roger Fry, Esq. TITLE: FMVSS INTERPRETATION TEXT: NOA-30 W. Roger Fry, Esq. Rendigs, Fry, Kiely & Dennis 900 Central Trust Bank Tower Fourth & Vine Streets Cincinnati, Ohio 45202 Dear Mr. Fry: This responds to your January 23, 1981, letter concerning tires used with multipiece rims. Specifically, you asked if this Department has considered whether tires should have a warning concerning use with mismatched multipiece rim assemblies. We have not considered this question, nor have our studies of multipiece rim explosions considered the tires involved. The agency has determined through its investigations that mismatched multipiece rim assemblies are dangerous. These mismatched assemblies are highly prone to explosive separation, regardless of the nature of the tire mounted on them. Accordingly, our efforts have been directed toward labeling requirements for rim components (see the enclosed copy of Federal Motor Vehicle Safety Standard No. 120) in an effort to reduce the incidence of mismatched multipiece rim assemblies. There are no labeling requirements for tires which specifically warn against use with mismatched multi-piece rim assemblies. Per your request, I have enclosed a copy of Federal Motor Vehicle Safety Standard No. 119, New Pneumatic Tires for Vehicles Other Than Passenger Cars (99 CFR S 571.119). Section S6.5 of this standard specifies the marking requirements for these tires. This standard took effect on March 1, 1975, and the enclosed copy represents the requirements which were applicable from that date to December 31, 1975.
This regulation does somewhat restrict the markings a manufacturer may put on the sidewall of its tires. For instance, the manufacturer cannot list more than one size designation (S6.5(c)) or more than one maximum load rating for single and dual loads (S6.5(d)). However, a manufacturer is free to include safety information in addition to that specified in section S6.5. Thus, a manufacturer might choose to print on the sidewall of its tires that the tires should only be used with a specified rim size or type. Such an additional warning need not be approved by this agency. In fact, this agency does not offer advance approval that a tire's markings comply with the requirements of Standard 119. It is the manufacturer's responsibility to determine that its tires are in compliance with applicable safety standards and to certify that compliance. If you have any further questions or need further information on this matter, please feel free to contact Mr. Stephen Kratzke of my staff at (202) 426-2992. Sincerely, Frank Berndt Chief Counsel Enclosures January 23, 1981 United States Dept. of Transporation National Highway Safety Administration Washington, D.C. 20591 Gentlemen: I am involved in a matter in which I represent the manufacturer of a truck tire which was on a vehicle when a multi-piece rim suddenly came off and critically injured someone in the immediate vicinity of the tire and rim. The rim had been assembled, in some manner with incompatible parts from different manufacturers, which parts combined both two-piece and three-piece rim assembly parts. My question of you surrounds the tire itself. Has the Department addressed the question of whether or not the tires shou1d have any kind of warning regarding use with either mismatched multi-piece rim assemblies, or multi-piece rim assemblies generally? I would be very interested in seeing your regulations and requirements governing data which is to be legible on the tire itself, auch as tire size, maximum air pressure and identifying marks. Could you send me your regulations which we in force in 1975? Do your regulations restrict the printing on tires to the specific items covered in your regulations, or is a tire manufacturer free to add and delete other messages? Must "other messages" be approved by you? Have your studies of injuries with multi-piece rim assemblies included consideration of the tires themselves? If so, to what extent? Thank you very much for any help you are ab1e to give me on this. Very truly yours, RENDIGS, FRY, KIELY & DENNIS W. Roger Fry WRF:rst |

ID: nht81-2.8OpenDATE: 03/24/81 FROM: AUTHOR UNAVAILABLE; F. Berndt; NHTSA TO: International Traders TITLE: FMVSS INTERPRETATION TEXT: This responds to your February 17, 1981, letter in which you requested information from this agency concerning "the grading standards applicable to truck tires." We have issued Uniform Tire Quality Grading Standards (49 Code of Federal Regulations @ 575.104) for passenger car tires which specify labeling information concerning the tire's treadwear, traction and heat resistance. However, these grading standards apply only to passenger car tires and, therefore, would not be applicable to the truck tires you purchase. There are, however, performance requirements applicable to truck tires, set forth in Federal Motor Vehicle Safety Standard No. 119 (49 Code of Federal Regulations @ 571.119), a copy of which is enclosed. The manufacturer of the truck tire must certify that the imported tire complies with the requirements of this standard by labeling the symbol "DOT" on the sidewall of the tire, according to the requirement of section S6.5(a) of the enclosed standard. This information may not be especially helpful to your company in comparing the price quotations, since every tire must have this certification to be legally imported into the United States. Should you need any further information concerning the requirements applicable to truck tires, please feel free to contact Mr. Stephen Kratzke of my staff at (202) 426-2992. Sincerely, ATTACH. INTERNATIONAL TRADERS February 17, 1981 National Highway Traffic Safety Administration -- Chief Counsel Dear Sir: We are in the process of gathering quotations for the import of truck tires for resale to heavy hauling trucking companies in the United States. We would appreciate receiving from you the grading standards for these tires. If you have any forms that are necessary for us to complete for you, please send these as well. Thank you. Very truly yours, Rusty D. Hitch |

ID: nht81-2.9OpenDATE: 03/25/81 FROM: AUTHOR UNAVAILABLE; F. Berndt; NHTSA TO: Koito Manufacturing Co., Ltd. TITLE: FMVSS INTERPRETATION TEXT: This is in reply to your letter of February 12, 1981, asking whether the placement of a clear lens cover in front of a motorcycle headlamp would be permissible under Federal Motor Vehicle Safety Standard No. 108. SAE Standard J580 (both a and b versions) Sealed Beam Headlamp Assembly is incorporated by reference in Tables I and III of the standard as one of the standards pertaining to headlamps for use on passenger cars, trucks, buses, and multipurpose passenger vehicles. Paragraph 5.2 of J580 states that, "When in use, a headlamp shall not have any styling ornament or other feature, such as a glass cover or grill, in front of the lens." The principal referenced SAE material for motorcycle headlamps is J584a Motorcycle Headlamps. As options, both J584 and S4.1.1.34 of Standard No. 108 allow, in effect, a motorcycle to be equipped with one half of any sealed beam system permissible on four-wheeled motor vehicles. We therefore view the prohibition of J580 as applicable to use of any sealed beam headlamp, regardless of the type of vehicle on which it is installed. Paragraph S4.1.3 of Standard No. 108 forbids the installation of additional equipment "that impairs the effectiveness of lighting equipment required" by Standard No. 108. Because of moisture accumulation, discoloration, cracks, etc., a glass or plastic cover might tend over a period of time to diminish or distort the headlamp beam. This is of particular concern with reference to the unsealed headlamps implicity permitted by SAE J584 because of the tendency of the reflector to deteriorate with age. The agency therefore has concluded that no motorcycle headlamp may have a glass shield in front of it when in use. |
