ID: aiam2263 Open Mr. G.E. Adams, Technical Manager, Dunlop Limited, Engineering Group, Holbrook Lane Coventry CV6 4AA, England; Mr. G.E. Adams Technical Manager Dunlop Limited Engineering Group Holbrook Lane Coventry CV6 4AA England; Dear Mr. Adams: This is in response to your letter of March 17, 1976, requestin information concerning steps which you, as a manufacturer of wheel equipment which will be offered for importation into the United States, must take in order to comply with all applicable National Highway Traffic Safety Administration regulations.; You should be aware of 49 CFR Part 566, Manufacturer Identification and 49 CFR Part 573, Defect Reports. In addition, Federal Motor Vehicle Safety Standard No. 119, New Pneumatic Tires for Vehicles Other Than Passenger Cars, may be of interest to you. Copies of these rules and an information sheet entitled 'Where to Obtain Federal Motor Vehicle Safety Standards and Regulations' are enclosed for your convenience.; Section 110(e) of the National Traffic and Motor Vehicle Safety Act (1 U.S.C. S1399(e)) requires every manufacturer who offers a motor vehicle or item of motor vehicle equipment for importation into the United States to designate a permanent resident of the United States as his agent, upon whom service of all processes, orders, notices, decisions, and requirements may be made.; The procedural regulations (49 CFR 551.45) for designation of agen pursuant to the Act requires that it include:; >>>(1) A certification by its maker that the designation is binding o Dunlop Limited under the laws, corporate bylaws, or other requirements governing the making of the designation at the time and place where it is made,; (2) The full legal name, principle place of business and mailin address of Dunlop Limited,; (3) Trade names or other designations of origin of the products o Dunlop Limited that do not bear its legal name,; (4) A provision that the designation of agent remain in effect unti with drawn or replaced by Dunlop Limited,; (5) A declaration of acceptance duly signed by the agent appointed which may be an individual, a firm, or a U.S. Corporation, and (6) The full legal name and address of the designated agent.<<<; A copy of the procedural regulation for designation of agent i enclosed for your convenience.; Sincerely, John Womack, Assistant Chief Counsel
ID: aiam2799 Open Mr. Joe Purko, Director, Bureau of Transportation, Room 4201, City Hall, Los Angeles, CA 90012; Mr. Joe Purko Director Bureau of Transportation Room 4201 City Hall Los Angeles CA 90012; Dear Mr. Purko: This responds to your March 10, 1978, question whether Standard No 121, Air Brake Systems, applies to a device that automatically applies to (sic) vehicle's service brakes when a sensing bumper mounted at the rear of the vehicle is tripped by contact with an object during backing maneuver. For purposes of your question, I assume that the vehicle, whether new or used, has been certified to comply with Standard No. 121 prior to installation of the device.; The answer to your question is no. Paragraph S3 (Applicability) o Standard No. 121 states that the standard applies to trucks, buses, and trailers equipped with air brake systems (with some specified exceptions). The standard therefore applies only to vehicles, and does not apply to motor vehicle equipment such as the braking actuator you describe. The vehicle must, of course, conform to Standard No. 121 following installation of the device, if the installation occurs prior to the first purchase in good faith for purposes other than resale.; After the first retail sale, S108(a)(2)(A) of the National Traffic an Motor Vehicle Safety Act (the Act) (15 U.S.C. S1397(a)(2)(A)) prohibits, with one exception, manufacturers, distributors, dealers, and repair businesses from knowingly rendering inoperative devices or elements of design installed in satisfaction on a safety standard such as Standard No. 121.; Sincerely, Joseph J. Levin, Jr., Chief Counsel
ID: aiam2633 Open Mr. John A. McLaine, Chief, Automotive Engineering Standards, State of New Jersey, Division of Motor Vehicles, 25 South Montgomery Street, Trenton, NJ 08666; Mr. John A. McLaine Chief Automotive Engineering Standards State of New Jersey Division of Motor Vehicles 25 South Montgomery Street Trenton NJ 08666; Dear Mr. McLaine: This is in reply to your letter of June 28, 1977, to Mr. Vinson of thi office, asking for our comments on the flashing of ambulance headlamps for signaling purposes. You enclosed a copy of a Bulletin dated June 27, 1977, that New Jersey recently sent to its Inspection Stations advising rejection of ambulances equipped with headlamp flashing devices.; Paragraph S4.6(b) of Federal Motor Vehicle Safety Standard No. 10 Lamps, Reflective Devices, and Associated Equipment, requires that lamps other than turn signals, hazard warning signals, and school bus warning signals be steady-burning in use, 'except that means may be provided to [automatically] flash headlamps . . . for signaling purposes.' The purpose of the exception was to allow continued use of automatic flashing devices in jurisdictions where it was permitted when the standard was adopted, for without the exception manufacture and sale of vehicles so equipped would have violated the National Traffic and Motor Vehicle Safety Act. The exception provided by S4.6(b) has a preemptive effect only in that a State cannot forbid the sale and registration of a vehicle equipped with a flashing device, but there is no restriction on a State's authority to forbid the use of such mechanisms when it deems it in the interests of traffic safety to do so.; Thus, we have no objection to New Jersey's Bulletin of June 27, 1977. Sincerely, Joseph J. Levin, Jr., Chief Counsel
ID: aiam0263 Open Mr. E. W. Bernitt, Vice President Safety and Quality Assurance, American Motors Corporation, Jeep Corporation, 940 North Cove Boulevard, Toledo, OH 43601; Mr. E. W. Bernitt Vice President Safety and Quality Assurance American Motors Corporation Jeep Corporation 940 North Cove Boulevard Toledo OH 43601; Dear Mr. Bernitt: This is in reply to your letter of October 12, 1970, to Mr. Charles A Baker of this office in which you requested an interpretation of the phrase 'effective projected illuminated area.'; Class A turn signal lamps are required by Section S3.1 of Federal Moto Vehicle Safety Standard No. 108, which references SAE Standard J588d in Tables I and III for these lamps. The requirements for the illuminated area of a turn signal lamp are specified in J588d as follows:; >>>'The effective projected illuminated area measured on a plane a right angles to the axle of the lamp must not be less than 12 sq. in. for Class A and 3-1/2 sq. in. for Class B.'<<<; In the 45 degree visibility requirements, this standard further state 'To be considered visible, the lamp must provide an unobstructed projected illuminated area of outer lens surface, including reflex,...'.; Our interpretation of effective projected illuminated area follows: Th effective projected illuminated area is that area of the lens measured on a plane at right angles to the axle of the lamp, including reflex reflector, which is not obstructed by an opaque object such as a mounting screw, mounting ring, or an ornamental basel or trim.; The above interpretation allows the area of rings or othe configurations (raised portions) molded in the lens to be considered part of the total effective area, even if this area does not contribute significantly to the total light output.; Sincerely, Roger Crampton, Director, Office of Operating Systems, Moto Vehicle Programs;
ID: aiam5431 Open Mr. Jerry Miller Director of Operations Associated Leasing Handicapable Vans 12117 Riverwood Drive Burnsville, MN 55337; Mr. Jerry Miller Director of Operations Associated Leasing Handicapable Vans 12117 Riverwood Drive Burnsville MN 55337; Dear Mr. Miller: This responds to your letter of May 31, 1994 requesting confirmation that 'there are no rules or regulations on wheelchair tie downs for vehicles other than school buses.' You are correct that Federal motor vehicle safety standard No. 222, School Bus Passenger Seating and Crash Protection, which includes requirements for wheelchair securement devices, applies only to school buses. However, while none of the safety standards apply to wheelchair securement devices for vehicles other than wheelchairs, the manufacturer of the product is subject to federal requirements concerning the recall and remedy of products with defects related to motor vehicle safety (49 U.S.C. 30118-30121). The agency does not determine the existence of defects except in the context of a defect proceeding. You should also be aware that the Department of Transportation has issued a final rule implementing the transportation provisions of the Americans with Disabilities Act. This final rule includes requirements for wheelchair securement devices installed in vehicles required to be accessible by this rule. A copy of the final rule is enclosed with this letter. If you have further questions on these regulations, please contact Mr. Irv Chor of the Federal Transit Administration. Mr. Chor's card is attached to the final rule. I hope you find this information helpful. If you have any other questions concerning NHTSA regulations, please contact Mary Versailles of my staff at this address or by phone at (202) 366-2992. Sincerely, John Womack Acting Chief Counsel Enclosure;
ID: aiam1921 Open Mr. Phil Martinez, Trailmaster Tanks, Inc., P.O. Box 13137, Fort Worth, TX 76118; Mr. Phil Martinez Trailmaster Tanks Inc. P.O. Box 13137 Fort Worth TX 76118; Dear Mr. Martinez: This responds to Trailmaster Tank's May 14, 1975, request for discussion of what constitutes the manufacture of a trailer in cases where used components from an existing vehicle are involved.; In response to a similar request from the Truck Trailer Manufacturer Association, the National Highway Traffic Safety Administration recently prepared a comprehensive discussion of this subject, a copy of which is enclosed for your information.; Yours truly, Richard B. Dyson, Assistant Chief Counsel
ID: aiam0633 Open Alberto Negro, Manager, D.C.R.S. USA Office, Fiat Motor Company, Inc., 560 Sylvan Avenue, Englewood Cliffs, NJ 07632; Alberto Negro Manager D.C.R.S. USA Office Fiat Motor Company Inc. 560 Sylvan Avenue Englewood Cliffs NJ 07632; Dear Mr. Negro: This is in reply to your letter of March 3, 1972, concerning multipl audible warning requirements.; The audible warning requirements of Federal Motor Vehicle Safet Standards 114 and 208 can be met with the use of one system rather than two separate ones.; Sincerely, E. T. Driver, Director, Office of Operating Systems, Moto Vehicle Programs;
ID: aiam2120 Open Mr. Charles A. Webb, President, National Association of Motor Bus Owners, 1025 Connecticut Avenue, N.W., Washington, DC 20036; Mr. Charles A. Webb President National Association of Motor Bus Owners 1025 Connecticut Avenue N.W. Washington DC 20036; Dear Mr. Webb: This is in response to your letters of November 12 and 13, 1975, i which you requested that the National Highway Traffic Safety Administration immediately suspend the effectiveness of Standard No. 121, Air Brake Systems, with respect to buses, without waiting until the end of a comment period. In a notice published November 13, 1975, 40 FR 52856, this agency proposed such a suspension with a 30-day comment period ending December 15, 1975.; Secretary Coleman has made clear his commitment to allowing adequat time for public comment on rulemaking actions. The normal minimum time for public comment on Department of Transportation actions has been established as 45 days. In this case, because of the special urgency of the matter, the period was reduced to 30 days. I believe we all recognize that this action is a significant one, affecting the performance and cost of most of the transit and intercity buses in the country. In these circumstances, it is our judgment that the 30-day period is the minimum that can be justified for comment by the interested public, and your request is therefore denied.; We also recognize, as you have pointed out, that for this short perio there may be some uncertainty and some interruption of normal activities within the affected industries. We will make every effort to reach and announce a decision as soon as possible after the end of the comment period.; Sincerely, James B. Gregory, Administrator
ID: aiam2570 Open Mr. Dennis G. Moore, Dry Launch, 1113 Greenville Road, Livermore, CA 94550; Mr. Dennis G. Moore Dry Launch 1113 Greenville Road Livermore CA 94550; Dear Mr. Moore: This is in reply to your letter of April 7, 1977, asking for clarification of S4.3.1.1.1 of Standard No. 108. Your initial question of December 27, 1976, was not clear to us hence the reason my answer of March 4, 1977, caused you some confusion.; The diagram in your letter of April 7 clearly depicts the exemptio provided by S4.3.1.1.1 for the specific reasons therein, that when a clearance lamp indicating overall width is not located on the rear of a vehicle it need not be visible at 45 degrees inboard. As the only required points of photometric measurement of a clearance lamp so located are to the rear and at 45 degrees outboard, the lamp need not be visible at any point in the 45 degree arc depicted in your letter.; Sincerely, Frank A. Berndt, Acting Chief Counsel
ID: aiam3731 Open Mr. Dale Scott, R.V. Account Executive, Kinder Division, Congoleum Corporation, 2323 South 17th Street, P.O. Box 1207, Elkhart, IN 46515; Mr. Dale Scott R.V. Account Executive Kinder Division Congoleum Corporation 2323 South 17th Street P.O. Box 1207 Elkhart IN 46515; Dear Mr. Scott: This responds to your letter to Mr. Kratzke of my staff, asking for a interpretation concerning Safety Standard No. 302, Flammability of Interior Materials (49 CFR S571.302). Specifically, you asked whether innerspring mattresses used in motor homes are subject to the requirements of that standard. You also asked for a definition of the term 'mattress cover.'; Section S4.1 of Standard No. 302 lists the components that are covere by the standard. That list states that mattress covers must comply with the standard's requirements, but not the innerspring mattress itself. Hence, the innerspring mattress with which you are concerned is not subject to the flammability requirements of Standard No. 302. As your letter noted, those mattress (sic) are subject to certain flammability requirements issued by the Consumer Product Safety Commission.; We have previously defined the term 'mattress cover' as including bot a cover that is used generally to enclose a mattress for cleanliness or sanitary purposes and the ticking permanently attached to the mattress to enclose the mattress filling or core. Both of these items would have to meet the requirements of Standard No. 302.; Should you have any further questions or need more information on thi subject, please contact Mr. Steve Kratzke of my staff at (202) 426- 2992.; Sincerely, Frank Berndt, Chief Counsel
