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: 7322Open Mr. Douglas Berg Dear Mr. Berg: This responds to your letter requesting that the National Highway Traffic Safety Administration provide "recognition and support" for your item of motor vehicle equipment, the "Hazard Helper Safety Sign." You explained that this reversible device attaches to the driver's window and displays either a help needed symbol (a stick figure with extended arms and legs) or a hazard alert symbol (a triangle). Your sales literature indicates that the help needed symbol is intended to be displayed in the event of medical emergencies, mechanical breakdown, having a flat tire, or being stuck in snow or being out of fuel. The hazard alert symbol is intended to be displayed for going for gasoline, doing roadside repairs, resting, or awaiting known assistance. As discussed below, this agency does not recognize, support or otherwise endorse particular products. Moreover, based on the information provided with your letter, it appears that your device would not comply with certain provisions of Federal Motor Vehicle Safety Standard No. 125, Warning Devices (49 CFR 571.125, copy enclosed). By way of background information, the National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1381 et seq., the "Safety Act") gives this agency the authority to issue safety standards applicable to new motor vehicles and new items of motor vehicle equipment. We have exercised this authority to establish Standard No. 125, Warning Devices. The Safety Act provides that no person shall "manufacture for sale, sell, offer for sale, or introduce or deliver for introduction in interstate commerce, or import into the United States" any new motor vehicle or new item of motor vehicle equipment unless the vehicles or equipment comply with the applicable standard. (See 15 U.S.C 1397(a)(1)(A).) NHTSA has no authority under the Safety Act to approve, certify, or otherwise endorse any commercial product. Instead, the Safety Act establishes a self-certification process under which each manufacturer is required to certify that each of its products meets all applicable Federal Motor Vehicle Safety Standard. (See 15 U.S.C. 1403.) I am enclosing a general information sheet explaining NHTSA's regulations. Section S3 of Standard No. 125 specifies that the standard "applies to devices, without self-contained energy sources, that are designed to be carried in motor vehicles, and used to warn approaching traffic of the presence of a stopped vehicle, except for devices designed to be permanently affixed to the vehicle." (Emphasis added.) Your device has no self-contained energy source, is designed to be carried in motor vehicles, and is not permanently affixed to the vehicle. Another condition set forth in S3 is that the device must be designed to be used to "warn approaching traffic of a stopped vehicle." Devices that are not intended to warn approaching traffic of a stopped vehicle, but only to alert passing traffic of the stopped vehicle's need for assistance, are not subject to Standard No. 125. An example of such a device would be a "HELP" message printed on a folding cardboard sunshade. The "help needed" portion of your device appears to be designed to function in the same manner as other non-warning devices, i.e., it does not appear to be intended to warn approaching traffic of a stopped vehicle, but to alert passing traffic that the stopped vehicle needs assistance. This portion of the device would therefore not be subject to Standard No. 125. However, the "hazard alert" portion of your device does appear to be intended to warn approaching traffic of a stopped vehicle, and must therefore comply with all of the requirements of Standard No. 125. From the enclosed copy of the standard you will see that some of the specific requirements with which your device must comply include minimum size, durability, material, container, labeling, configuration, color, reflectivity, luminance, and stability. From the information you provided with your letter, it appears that your device would not comply with several of these requirements. Please be aware that violations of Safety Act provisions are punishable by civil fines of up to $1,000 for each violation of a safety standard. In addition, the Act requires manufacturers to remedy their products if they fail to comply with any applicable safety standards. I hope this information is helpful. If you have any further questions about NHTSA's safety standards, please feel free to contact Marvin Shaw of my staff at this address or by telephone at (202) 366-2992. Sincerely, Paul Jackson Rice Chief Counsel Enclosure Ref:125 d:7/28/92

ID: nht91-1.33OpenDATE: February 1, 1991 FROM: Paul Jackson Rice -- Chief Counsel, NHTSA TO: Jeffrey S. Malinowski -- Small Business Center TITLE: None ATTACHMT: Attached to letter dated 11-14-90 from Jeffrey S. Malinowski to Paul Jackson Rice (OCC 5461) TEXT: This responds to your letter on behalf of Mr. Leo McCallum, asking whether any Federal Motor Vehicle Safety Standard applies to his invention, a tie rod, safety bracket. You stated that the product would typically be installed by a vehicle owner to reduce tie rod end wear. As explained below, while no Federal safety standard directly applies to your client's product, he may nevertheless have certain responsibilities under this agency's regulations. As way of background information, the National Traffic and Motor Vehicle Safety Act of 1966, as amended (the Safety Act") authorizes the National Highway Traffic Safety Administration (NHTSA) to issue safety standards applicable to motor vehicles and items of motor vehicle equipment. The Safety Act also requires that these safety standards establish minimum levels of performance for vehicles or equipment. Once the necessary performance level has been established, vehicle or equipment manufacturers are free to choose any means they wish to achieve the required level of performance. In other words, the safety standards do not require the use of any particular manufacturer's product or particular materials; the standards permit the use of any manufacturer's product that achieves the necessary performance level. Section 114 of the Safety Act (15 U.S.C. 1403) requires manufacturers to certify that each of its vehicles or items of motor vehicle equipment complies with all applicable safety standards. NHTSA does not approve, endorse, or certify any motor vehicle or item of motor vehicle equipment. NHTSA has no safety standard directly about tie rods or safety brackets used with tie rods. As for installation of your client's device on vehicles in the aftermarket, such installations may be limited by section 108(a)(2)(A) of the Safety Act (15 U.S.C. 1397(a)(2)(A)). That section prohibits any manufacturer, distributor, dealer, or motor vehicle repair business from knowingly rendering inoperative any device or element of design installed on or in a motor vehicle in compliance with an applicable safety standard. If installation of your client's product resulted in a vehicle no longer complying with a safety standard, a manufacturer, distributor, dealer, or repair business that installed the product would have rendered inoperative a device or element of design installed on the vehicle in compliance with a standard. To avoid a "rendering operative" violation, your client should examine his product to determine if installing his product would result in the vehicle no longer complying with a standard's requirements. Section 109 of the Safety Act (15 U.S.C. 1398) specifies a civil penalty of up to $1,000 for each violation of the render inoperative provision.
Please note that the Safety Act does not establish any limitations on an individual vehicle owner's ability to alter his or her own vehicle. Under Federal law, individual owners can install any device they want on their own vehicles, regardless of whether that device renders inoperative the vehicle's compliance with a safety standard. Other statutory provisions in the Safety Act could affect your client's product. Manufacturers of motor vehicle equipment such as the "tire rod safety bracket" are subject to the requirements in sections 151-159 of the Safety Act (15 U.S.C. 1411-1419) on the recall and remedy of products with defects related to motor vehicle safety. The Safety Act specifies that if either the manufacturer or this agency determines that a safety-related defect exists in your client's product, your client as the manufacturer must notify purchasers of the safety-related defect and must either: (1) repair the part so that the defect is removed; or (2) replace the part with an identical or reasonably equivalent part which does not have a defect. Whichever of these options is chosen, the manufacturer must bear the full expense and cannot charge the owner for the remedy if the equipment was purchased less than eight years before the notification campaign. I hope this information is helpful. If you have any further questions, please feel free to contact Marvin Shaw of my staff at this address or by telephone at (202) 366-2992. |

ID: nht92-3.33OpenDATE: October 1, 1992 Est. FROM: Paul Jackson Rice -- Chief Counsel, NHTSA TO: C. Morris Adams TITLE: None ATTACHMT: Attached to letter dated 9/24/92 from C. Morris Adams to Paul Jackson Rice (OCC-7768) TEXT: This responds to your FAX of September 24, 1992, requesting a ruling regarding the legality of lap belts at the passenger seats on school buses. As explained below, Federal law has long required lap or lap/shoulder belts to be installed at every passenger seating position on small school buses. Federal law has also long permitted, but not required, lap or lap/shoulder belts to be installed at passenger seating positions on large school buses, provided that those belts do not adversely affect the large school bus's compliance with the applicable safety standards. This is still the agency's position. As you know, in 1977, NHTSA issued Federal Motor Vehicle Safety Standard No. 222, School Bus Passenger Seating and Crash Protection, which established minimum levels of crash protection that must be provided for occupants of all school buses. For large school buses (those with a gross vehicle weight rating (GVWR) of more than 10,000 pounds), the standard requires occupant protection through a concept called "compartmentalization" -- strong, well-padded, well-anchored, high-backed, evenly spaced seats. Small school buses (those with a GVWR of 10,000 pounds or less) must provide "compartmentalization" and be equipped with lap or lap/shoulder belts at all passenger seating positions. The agency believes that safety belts are necessary in addition to "compartmentalization" in small school buses because of their smaller size and weight, which are closer to that of passenger cars and light trucks. Ever since 1977, NHTSA has indicated that Federal law permits lap or lap/shoulder belts to be installed at the passenger seating positions on large school buses as long as the vehicle would still comply with all applicable safety standards, including Standard No. 222. NHTSA has no information to indicate that installation of seat belts at the passenger seating positions on a large school bus would affect the bus's compliance with any safety standard. The allegations in your FAX that using seat belts in large school buses will result in crash forces producing concentrated loading on the head, instead of being spread evenly over the upper torso as is the case without a seat belt, are nearly identical with the explanations included in a 1985 Transport Canada report on school bus safety. NHTSA carefully evaluated and considered the Canadian report and these explanations in connection with its rulemaking action considering whether to specify requirements for voluntarily installed seat belts on large school buses. 54 FR 11765; March 22, 1989. After fully considering the Canadian report, the agency stated at 54 FR 11770: NHTSA shares commenters' concerns about any implications that safety belts negatively affect the protection provided to passengers on large school buses. However, the agency is not aware of accident data showing an injury caused or made more serious by the presence of safety belts on a school bus. Furthermore, NHTSA cannot conclude from the Canadian report's findings that belts actually degrade the benefits of compartmentalization to the extent that the supplemental restraint system renders inoperative the safety of large school buses, but the possibility exists that the occupant kinematics shown in the Canadian tests could occur. The agency then identified some possible safety benefits that could result from seat belts in large school buses, benefits that were not considered in the Canadian tests. The agency concluded that, "Although these benefits are not significant enough to justify a Federal requirement for the installation of safety belts on all large school buses, they are enough to provide a basis upon which the agency will decline to prohibit the installation of belts on large school buses." 54 FR 11765, at 11770; March 22, 1989. I have enclosed a copy of this notice for your information. As you can see, NHTSA has carefully considered the subject raised in your FAX and reviewed all available information in this area. After that review, the agency concluded that there was no justification for changing its longstanding position that persons that wish to do so should be permitted to install seat belts at passenger seating positions in large school buses. Your letter did not provide any data that NHTSA had not already considered. Hence, there is no basis for the agency to change its longstanding position in this area. I hope you find this information helpful. If you have any other questions, please contact Mary Versailles of my staff at this address or by phone at (202) 366-2992. |

TITLE: NONE ATTACHMT: ATTACHED TO LETTER DATED 05/31/90 FROM STEPHEN P. WOOD -- NHTSA TO WILLIAM D. FALCON; REDBOOK A35; STANDARD 201; 202; 205; VSA 108[A][2][A]; LETTER DATED 01/30/89 FROM WILLIAM D. FALCON TO RALPH HITCHCOCK -- NHTSA; OCC 3107; LETTER FROM STEVE C ROWELL; DATED 11/02/88 EST TEXT: Commission on Accredidation for Law Enforcement Agencies Inc. 4242b Chain Bridge Rd. Fairfax, Va 22030 Dear Ms. Denniston, Mr. Bittner and Mr. Medeiros; The automobile interior partitions used in all cruisers I have observed seem to lack some legal requirements. The Motor Vehicle Safety At of 1966 (U.S. Public Law 89-563) sets forth the following requirements; 49 CFR Ch.V (10/1/86 Edition) ** Sect. 567.7 Requirements For Persons Who Alter Certified Vehicles- A person who alters a vehicle that previously has been certified in accordance with sect 567.4 or 567.5 . . . . shall allow the original certification label to remain on the vehicle , and shall affix to the vehicle an additional label . . . . containing the following information: "This vehicle was altered by (individual or corporate name) in (month and year in which alterations were completed) and as altered it conforms to all appli cable Federal Motor Vehicle Safety Standards affected by the alteration and in effect in (month, year). ** Sect. 571.107 Standard No. 107; Reflecting Surfaces. This standard specifies reflecting surface requirements for certain vehicle components in the driver's field of view. ** Sect 571.111 Standard 111; Rearview mirrors. This standard specifies requirements for the performance and location of rearview mirrors . . . to reduce the number of deaths and injuries that occur when the driver does not have a clear and reasonabl y unobstructed view to the rear. ** Sect. 571.201 Standard No. 201; Occupant protection in interior impact. This standard specifies requirements to afford impact protection for occupants. s3.2 Seat backs-when that area of the seat back that is within the head impact area (head impact area means all nonglazed surfaces of the interior of a vehicle that are statically contactable by a 6.5-inch dimeter spherical head form of a measuring device having a pivot point to "top of head" dimension infinitely adjustable from 29 to 33 inches in accordance with the following proceedure etc.). ** Sect 571.205 Standard No. 205; This standard specifies requirements for glazing materials for use in motor vehicles and motor vehicle equipment. The purpose of this standard is to reduce the injuries resulting from impact to glazing surfaces, to e nsure a necessary degree of transparency in motor vehicle windows for driver visibility, and to minimize the possibility of occupants being thrown through the vehicle windows in collisions. S5.1.1.3 the following locations are added to the lists specifi ed in ANS Z26 in which item 6 and item 7 safety glazing may be used: (k.1.1.2 Interior partitions). Your prompt response to my letter of 1/4/88 is greatly appreciated, however I have noticed a slight oversight in Standard 71.4.1 Transport Equipment. Specifically the mention of wire mesh in this recommendation for the use of a "Safety Barrier". To i dentify an interior partiton (the words used by the D.O.T. for this device) as a "safety barrier" is an oxymoron given the safety hazards inherent in the designs currently being used. Statistics on bodily injury losses occuring in cruisers seem difficult to obtain, but not so for cabs. The graphs enclosed indicate that when and where interior partitions are used in taxis there is enhanced retention of control for the operation of the vehicle accompanied by epidemic increase in accident fatality and bodily injury loss. It seems that the only way to incur more accident fatality in fewer accidents and more injury with less property damage is to introduce occupant impact hazards. It is my belief that enhancement in the design of interior partitions will still afford the safety of enhanced operator retention of control and additionally reduce the likelyhood of injury to occupants (front or rear compartments) in the event of a s udden stop or collision. The economic impact of these hazards in the taxi industry in Boston has been astronomical. Prior to the use of interior partitions in Boston taxis (from 1950-1970) the cost of insurance for taxis was only twice that of the cost for private vehicles i n Boston (given that |

ID: nht92-7.28OpenDATE: April 27, 1992 FROM: Paul Jackson Rice -- Chief Counsel, NHTSA TO: Kevin J. Stoll -- Technical Advisor, Russell Products, Inc. TITLE: None ATTACHMT: Attached to letter dated 2/27/92 from Kevin J. Stoll to Taylor Vinson (OCC 7066) TEXT: This responds to your letter of February 27, 1992, to Taylor Vinson of this Office asking several questions relating to center high-mounted stop lamps. Your questions are: "1. Are the LED (light emitting diode) being used for third brake light legal? If so, what are the specifications so that they can be used as a third brake light?" A center high-mounted stop lamp whose illumination is provided by LEDs is legal, provided that the light meets the photometric specifications for such lamp specified in Figure 10 of Motor Vehicle Safety Standard No. 108, and all other requirements. "2. a. Where are the truck manufacturers ie. GM, Ford, Dodge locating the third brake light on pickup trucks? b. What effect will this have on truck cap manufacturers and the dealer responsibility to the consumer? c. Can the dealer wire directly to the existing third brake light harness used to light up the factory third brake light?" With respect to (a), the center lamp may be installed at any point on the rear vertical centerline of pickup trucks. Because this requirement is not effective until September 1, 1993, we have no specific knowledge as to where the manufacturers of pickup trucks will locate the lamps. With respect to (b), NHTSA discussed the relationship of center high-mounted stoplamps to aftermarket slide-in campers or caps in the preamble to the final rule adopting the requirement. I enclose a copy of the rule (56 FR 16015) with our discussion highlighted on pages 16017 and 16018. After reading this material, if you have further questions regarding the effect on truck cap manufacturers and dealers, we shall be pleased to answer them.
With respect to (c), we assume that the situation you envision is that a truck cap has been manufactured with a center stop lamp and the dealer is installing the cap on a pickup truck. If the cap is being permanently installed, the dealer may wire the cap's lamp directly to the existing center lamp light harness, as the cap lamp is intended as a surrogate for the original lamp. If the cap is removable, the dealer may also wire in the manner you discuss, provided that when the cap is removed (and the cap lamp disconnected) the original lamp will perform in conformance with Standard No. 108. The specific connections to be made should be done in accordance with the vehicle manufacturer's recommendations. "3. a. We have a customer that would like to mount a flush mounted third brake light in the rear glass window of a truck cap. This window is used also as the rear access door to get to the truck bed from the outside of the truck. b. This would allow the third brake light to be moveable and not stationery. If a consumer would have an object in the bed of the truck with the window in the open position, allowing for the third brake light to be left in an upward position and no longer viewed from the rear. Would this application be approved?" The agency has no authority to approve or disapprove specific designs. We can advise you as to whether designs appear to conform or not to conform with the applicable laws of our agency. Conformance with Standard No. 108 is determined with respect to the vehicle in its normal operating state. With respect to your question, this would be with the pickup cap window in its closed position. Thus, your design does not raise a question of conformance with Standard No. 108. "4. Could you please enter Russell Products, Inc. on your mailing lists for all future updated rulings on third brake lights passed or discussed at all committee meetings?" We do not maintain a mailing list of any sort. However, "rulings" are not "passed" at "committee meetings" but are published in the Federal Register, initially as proposed rules affording a minimum of 45 days in which to comment. After evaluation of comments, a final rule may be published, with an effective date no earlier than 30 days after issuance. We believe it likely that any future proposals and amendments would be publicized, and that you would be likely to hear of them. There are no current plans to amend these requirements. |

ID: nht92-7.37OpenDATE: April 17, 1992 FROM: Paul Jackson Rice -- Chief Counsel, NHTSA TO: Michael J. Sens -- Researcher, S.E.A., Inc. TITLE: None ATTACHMT: Attached to letter dated 3/26/92 from Michael J. Sens to Paul J. Rice (OCC 7135) TEXT: This responds to your letter to me dated March 26, 1992, in which you sought our interpretation of whether the requirements of Federal Motor Vehicle Safety Standards 206, Door Locks and Door Retention Components; 214, Side Door Strength; and 216, Roof Crush Resistance -- Passenger Cars, applied to a 1985 American Motors Corporation (AMC) Jeep CJ-7. You stated in your letter that AMC classified the vehicle as a "sport utility vehicle" and that it came with a soft top or an optional fiberglass top, both with removable side doors. By way of background information, the National Traffic and Motor Vehicle Safety Act of 1966 (Safety Act), 15 U.S.C., S1381, et seq., as amended, authorizes the National Highway Traffic Safety Administration (NHTSA) to issue safety standards for new motor vehicles and items of motor vehicle equipment. All motor vehicles and items of motor vehicle equipment manufactured or imported for sale in the United States must comply with all applicable safety standards. In accordance with 49 CFR 567, Certification, manufacturers of motor vehicles must certify that their products comply with all such standards. Each safety standard applies to specified "types" of motor vehicles and/or motor vehicle equipment. Motor vehicles are classified into the following types: passenger cars, multipurpose passenger vehicles, trucks, buses, trailers, and motorcycles. A definition for each motor vehicle type is set forth at 49 CFR 571.3. Thus, a 1985 AMC Jeep CJ-7 was required to comply with all safety standards that applied to its vehicle type at the time of its manufacture. In order to determine what safety standards applied to the vehicle, it is first necessary to establish its classification under Part 571.3. The 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 classification before the manufacturer itself has classified a particular vehicle. NHTSA may reexamine the manufacturer's classification during the course of any enforcement actions.
While AMC may have marketed the 1985 AMC Jeep CJ-7 as a "sport-utility vehicle," it classified it as a multipurpose passenger vehicle for purposes of the Federal motor vehicle safety standards. The term "multipurpose passenger vehicle" is defined in Part 571.3 as "a motor vehicle with motive power, except a trailer designed to carry 10 persons or less which is constructed either on a truck chassis or with special features for occasional off-road operation." It is our opinion that AMC's classification was appropriate, given that the 1985 Jeep CJ-7 is a 4-wheel drive vehicle with an approach angle of 33 degrees, departure angle of 25 degrees, breakdown angle of 18 degrees, axle clearance of 7.8", and minimum running clearance of 8.1", and thus clearly has special features for occasional off-road operation. With specific reference to the three standards you inquired about concerning possible applicability to a 1985 AMC Jeep CJ-7, Standards 214 and 216 applied only to passenger cars at the time the CJ-7 was manufactured. See S2 of Standard 214 and and S3 of Standard 216. Since the 1985 AMC Jeep CJ-7 was classified as a multipurpose passenger vehicle and not a passenger car, those two standards, by their terms, did not apply to it. Standard 206, on the other hand, did apply to multipurpose passenger vehicles as well as passenger cars. However, S4 thereof provided in pertinent part: ". . . (C)omponents on folding doors, roll-up doors, doors that are designed to be easily attached to or removed from motor vehicles manufactured for operation without doors, . . . need not conform to this standard." You indicated that the Jeep CJ-7 came with removable side doors, and we understand that the vehicle was manufactured for operation without doors. Accordingly, the AMC Jeep CJ-7 came within the above-quoted exception to Standard 206 and was not subject to its requirements. I hope the above information will be helpful to you. If you have any further questions or need additional information regarding this matter please feel free to contact Walter Myers of my staff at this address or by telephone at (202) 366-2992. |

ID: nht92-7.44OpenDATE: April 10, 1992 FROM: Paul Jackson Rice -- Chief Counsel, NHTSA TO: Lance Watt -- Director of Engineering, The Flxible Corporation TITLE: None ATTACHMT: Attached to letter dated 2/11/92 from Lance Watt to Paul J. Rice (OCC 6972) TEXT: This responds to your letter of February 11, 1992, asking for an interpretation of Motor Vehicle Safety Standard No. 108 as it relates to several scenarios regarding the wiring and use of optional brake retarder transmissions on city transit buses manufactured by your company. In your current design, the retarder is designed so that it is electrically operated during the initial travel of the service brake pedal. As the service brake pedal is further depressed, the service brakes are activated, and this in turn illuminates the stop lamps. You have enclosed a copy of my letter of September 20. 1990, confirming that this design conforms to Standard No. 108, specifically S5.5.4 which states that "The stop lamps on each vehicle shall be activated upon application of the service brakes." Since that time, several additional scenarios have presented themselves. First, some customers have requested that the transmission retarder be activated when the accelerator pedal is released, rather than when the brake pedal is applied. In this configuration, the stop lamps would not be illuminated, "and therefore, following vehicles may be unaware of this sudden reduction in vehicle speed", unless the service brakes were also applied. However, some customers wishing this option would like to have the stop lamps illuminated by the retarder, that is to say, when the accelerator is released. Second, some customers have also requested a retarder cut-off switch in order to disable the retarder during icy or slippery road conditions. In such a case, the stop lamps would also be activated at the time of accelerator release "with minimal if any change in vehicle forward speed, and again, potentially with no intent on the part of the driver to use the service brakes." To date, your company has resisted these requests, but these customers, without a specific NHTSA interpretation on the point, threaten to declare your company a nonresponsive bidder on transit bus procurements. You have asked whether a noncompliance with section S5.5.4 would result "if the stop lamps were activated without depressing the brake pedal as requested by our customers." The purpose of the retarder feature is to provide supplemental braking to city transit buses. This braking results in the deceleration of the vehicle. A stop lamp is defined by SAE Standard J1398 MAY85 Stop Lamps for Use on Motor Vehicles 2032 mm or More in Overall Width as one that indicates "the intention of the operator of a vehicle to stop or diminish speed by braking." Whenever the brake retarder is activated with the intent of diminishing speed by braking, Standard No. 108 does not require that the stop lamps be activated. The only mandate of the standard (S5.5.4) is that when the service brakes are applied, the stop lamps must be illuminated. Nor does Standard No. 108 prohibit illumination of the stop lamps by release of the accelerator pedal followed by activation of the retarder. This is because the intention of the driver is to diminish speed by the braking action of the retarder. We distinguish this situation from the one in an interpretation provided Larry Snowhite, Esq. on January 25, 1990, in which a device activated the stop lamps whenever the accelerator pedal was released, regardless of the intent of the driver. Activation of the stop lamps initiated by release of the accelerator pedal is permissible only when the intent of the driver is to reduce the speed of the vehicle by an immediate subsequent act of braking, whether that is achieved through his use of the service brake system, use of retarders, or a combination of the two. However, a configuration where the stop lamps operate in the absence of service brake application or activation of a retarder system (as appears to occur when a retarder cut off switch has been activated) would be subject to S5.1.3 of the standard. This prohibits the installation of motor vehicle equipment that impairs the effectiveness of the lighting equipment required by Standard No. 108. In this instance, the retarder cut off feature would permit the stop lamps to send the false signal that the operator intended to stop or reduce vehicle speed when, in fact, there was no intent to do so.

ID: nht92-5.7OpenDATE: July 28, 1992 FROM: Paul Jackson Rice -- Chief Counsel, NHTSA TO: Douglas Berg -- President, Ascend Productions TITLE: None ATTACHMT: Attached to letter dated 5/15/92 from Douglas Berg to NHTSA Legal Council (OCC 7322) TEXT: This responds to your letter requesting that the National Highway Traffic Safety Administration provide "recognition and support" for your item of motor vehicle equipment, the "Hazard Helper Safety Sign." You explained that this reversible device attaches to the driver's window and displays either a help needed symbol (a stick figure with extended arms and legs) or a hazard alert symbol (a triangle). Your sales literature indicates that the help needed symbol is intended to be displayed in the event of medical emergencies, mechanical breakdown, having a flat tire, or being stuck in snow or being out of fuel. The hazard alert symbol is intended to be displayed for going for gasoline, doing roadside repairs, resting, or awaiting known assistance. As discussed below, this agency does not recognize, support or otherwise endorse particular products. Moreover, based on the information provided with your letter, it appears that your device would not comply with certain provisions of Federal Motor Vehicle Safety Standard No. 125, Warning Devices (49 CFR 571.125, copy enclosed). By way of background information, the National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1381 et seq., the "Safety Act") gives this agency the authority to issue safety standards applicable to new motor vehicles and new items of motor vehicle equipment. We have exercised this authority to establish Standard No. 125, Warning Devices. The Safety Act provides that no person shall "manufacture for sale, sell, offer for sale, or introduce or deliver for introduction in interstate commerce, or import into the United States" any new motor vehicle or new item of motor vehicle equipment unless the vehicles or equipment comply with the applicable standard. (See 15 U.S.C 1397(a)(1)(A).) NHTSA has no authority under the Safety Act to approve, certify, or otherwise endorse any commercial product. Instead, the Safety Act establishes a self-certification process under which each manufacturer is required to certify that each of its products meets all applicable Federal Motor Vehicle Safety Standard. (See 15 U.S.C. 1403.) I am enclosing a general information sheet explaining NHTSA's regulations. Section S3 of Standard No. 125 specifies that the standard "applies to devices, without self-contained energy sources, that are designed to be carried in motor vehicles, and USED TO WARN APPROACHING TRAFFIC OF THE PRESENCE OF A STOPPED VEHICLE, except for devices designed to be permanently affixed to the vehicle." (Emphasis added.) Your device has no self-contained energy source, is designed to be carried in motor vehicles, and is not permanently affixed to the vehicle. Another condition set forth in S3 is that the device must be designed to be used to "warn approaching traffic of a stopped vehicle." Devices that are not intended to warn approaching traffic of a stopped vehicle, but only to alert passing traffic of the stopped vehicle's need for assistance, are not subject to Standard No. 125. An example of such a device would be a "HELP" message printed on a folding cardboard sunshade. The "help needed" portion of your device appears to be designed to function in the same manner as other non-warning devices, i.e., it does not appear to be intended to warn approaching traffic of a stopped vehicle, but to alert passing traffic that the stopped vehicle needs assistance. This portion of the device would therefore not be subject to Standard No. 125. However, the "hazard alert" portion of your device does appear to be intended to warn approaching traffic of a stopped vehicle, and must therefore comply with all of the requirements of Standard No. 125. From the enclosed copy of the standard you will see that some of the specific requirements with which your device must comply include minimum size, durability, material, container, labeling, configuration, color, reflectivity, luminance, and stability. From the information you provided with your letter, it appears that your device would not comply with several of these requirements. Please be aware that violations of Safety Act provisions are punishable by civil fines of up to $1,000 for each violation of a safety standard. In addition, the Act requires manufacturers to remedy their products if they fail to comply with any applicable safety standards. I hope this information is helpful. If you have any further questions about NHTSA's safety standards, please feel free to contact Marvin Shaw of my staff at this address or by telephone at (202) 366-2992. |

ID: Spelcast5635OpenMr. Derek Fletcher Dear Mr. Fletcher: This responds to your e-mail letter and phone conversation with Ms. Deirdre Fujita of my staff, in which you requested a temporary exemption from the child restraint anchorage system requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 213, Child restraint systems. The agency does not have authority to grant exemptions to equipment manufacturers. However, in this limited instance, we will exercise our discretion not to institute enforcement proceedings with respect to the Spelcast special needs child restraint system (CRS). In your letter, you explained that the Spelcast is specifically designed to safely transport children in hip spica casts or with other lower extremity casting. You stated that typically, a child only uses the Spelcast for a period of 6 to 8 weeks while in a cast. According to your letter, hospitals temporarily loan the Spelcast to individuals with children in casts. You describe the loans as being administered by trained hospital staff, who provide instruction on the restraints installation and use. Under FMVSS No. 213, all CRSs (except harnesses, car beds, and belt-positioning seats) manufactured on or after September 1, 2002, must be equipped with a means of attaching to a vehicles child restraint anchorage system [1] . This requirement, along with vehicle anchorage requirements, improves the compatibility of vehicle seats and CRSs and provides a universal system for installing CRSs. Increasing the ease of installation reduces the instances of incorrectly installed restraints. Improved compatibility and proper installation increase the effectiveness of a CRS in preventing death or injury. You indicated that the Spelcast is currently not offered for sale because it does not meet the LATCH requirements of FMVSS No. 213. However, you stated that when the Spelcast was sold, it was primarily sold to hospitals and child passenger safety agencies and was not available through any retail outlet. You stated that there are currently no other CRSs available that accommodate the needs of children in casts and that the only alternative is ambulance transport. As a CRS, the Spelcast must meet all applicable provisions of FMVSS No. 213, including those for the child restraint anchorage system attachments. When a Federal motor vehicle safety standard contains a requirement applicable to a product, Federal law prohibits any person from manufacturing, selling, or importing a new product that does not comply with that requirement. See, 49 U.S.C. 30112. The Federal law governing our agency does not explicitly provide for exempting manufacturers of equipment items, such as CRSs, from the application of the standards. However, we believe that flexibility is called for to accommodate the special medical needs of the individuals who rely on your product. The Spelcast provides a transportation option for a small population that has very limited alternatives. One of the objectives of the LATCH requirements is to minimize improper installation of CRSs. Because of the distribution methods for the Spelcast, users receive personal instruction from qualified staff. This instruction, combined with the limited and controlled distribution of the child restraint, reduces the chance that a Spelcast will be improperly installed. However, to continue to ensure that only properly instructed individuals would use these seats and to prevent the seats general use, a system is needed to ensure that a loaned seat is returned to the hospital or agency once a child can be accommodated by a CRS certified to all the requirements of FMVSS No. 213. In your phone conversation, you explained that the seat is being redesigned in cooperation with another CRS manufacturer to comply with the LATCH requirements, but that the availability of the new seat is still about 8 months away. Based on this and other information mentioned in this letter, we will exercise our discretion not to enforce the child restraint anchorage system requirements of FMVSS No. 213 against the Spelcast for a period of 8 months from the date of this letter. This will provide an alternative to ambulance transport until the redesigned seat is available. Note that this determination applies only to the child restraint anchorage provisions of FMVSS No. 213 and that the Spelcast must still comply with all other relevant portions of the standard. I hope that this letter resolves your problem. If you have any further questions, please contact Mr. Chris Calamita of my staff at (202) 366-2992. Sincerely, Jacqueline Glassman ref:213 [1] This is commonly referred to as the LATCH (lower anchors and tether for children) requirement. |

ID: usedchasOpen Dennis T. Snyder, Esquire Dear Mr. Snyder: This is in response to your letter of May 11, 1995, asking whether a client of yours is a "final stage manufacturer" within the meaning of the National Traffic and Motor Vehicle Safety Act and implementing regulations on manufacturer identification and vehicle certification found in 49 CFR Parts 566, 567, and 568. You have described this client as being engaged in the manufacture of completed heavy duty dump trucks, vans, and road tractors from used chassis-cabs. The term "manufacturer" is defined in 49 U.S.C. ' 30102(a)(5) (formerly section 102(5) of the National Traffic and Motor Vehicle Safety Act) as "a person- (A) manufacturing or assembling motor vehicles or motor vehicle equipment . . . " (emphasis added). Based on your description of your client as being engaged in the assembly of completed motor vehicles, it would appear to meet this definition. Because the manufacturer identification requirements of 49 CFR Part 566 apply to "all manufacturers of motor vehicles," as stated in section 566.3 of that Part, your client would be required to submit to the National Highway Traffic Safety Administration (NHTSA) the identifying information specified in 49 CFR 566.5. The term "final stage manufacturer" is defined at 49 CFR 568.3 as "a person who performs such manufacturing operations on an incomplete vehicle that it becomes a completed vehicle." An "incomplete vehicle" is defined in that section as "an assemblage consisting, at a minimum, of frame and chassis structure, power train, steering system, suspension system, and braking system . . . that requires further manufacturing operations . . . to become a completed vehicle." The term "completed vehicle" is in turn defined in section 568.3 as "a vehicle that requires no further manufacturing operations to perform its intended function . . . ." Based on your description of your client as being engaged in the manufacture of completed heavy duty dump trucks, vans, and road tractors from chassis-cabs, it would qualify as a final stage manufacturer, as that term is defined in section 568.3. Requirements for final stage manufacturers are specified at 49 CFR 568.6. This section provides that a final stage manufacturer shall complete each vehicle "in such a manner that it conforms to the [Federal motor vehicle safety] standards in effect on the date of manufacture of the incomplete vehicle, the date of final completion, or a date between those two dates," and shall affix a label to the vehicle attesting to that conformance in accordance with 49 CFR 567.5, which specifies certification requirements for vehicles manufactured in two or more stages. These certification requirements are in implementation of 49 U.S.C. ' 30115, which requires the manufacturer of a new motor vehicle to certify to the dealer or distributor at delivery that the vehicle complies with applicable motor vehicle safety standards. NHTSA has long taken the position, however, that a vehicle is used if it is assembled by adding a new body to the chassis of a vehicle previously registered for use on the public roads. As a consequence, your client would not be required to certify the vehicles that it manufactures in this fashion. Your client would nevertheless be subject to 49 U.S.C. ' 30122(b), which provides that "[a] manufacturer, distributor, dealer, or motor vehicle repair business may not knowingly make inoperative any part of a device or element of design installed on or in a motor vehicle . . . in compliance with an applicable motor vehicle safety standard . . . ." NHTSA has interpreted this provision as requiring any of the specified entities that remove an old body from a vehicle in order to install a new one to ensure that the newly completed vehicle meets the standards that the vehicle was originally required to meet. For example, a vehicle consisting of a body manufactured in 1995 mounted on a used 1989 chassis must meet all standards that applied to 1989 vehicles. Your client would be liable for any violation of this requirement on vehicles that it manufactures, regardless of whether it removed the body from the old vehicle itself, or directed another entity to do so. Additionally, as a vehicle manufacturer, your client would be required under 49 U.S.C. ' 30118 to furnish owners with notification of, and a remedy for, any safety-related defect or any noncompliance with an applicable Federal motor vehicle safety standard that is found to exist in a vehicle that it assembles. If you have any further questions regarding this matter, feel free to contact Coleman Sachs of my staff at the above address, or by telephone at (202) 366- 5238. Sincerely,
John Womack Acting Chief Counsel ref:566#VSA d:6/13/95
