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: nht74-2.31OpenDATE: 02/06/74 FROM: AUTHOR UNAVAILABLE; Richard B. Dyson; NHTSA TO: Kar-Kraft, Inc. TITLE: FMVSS INTERPRETATION TEXT: This is in further reply to your letter of December 6, 1973, in response to your phone conversation with Mike Peskoe on February 25, 1974. You indicated then that our reply of February 6, 1974, failed to define "lowest seating position" as that term is used with respect to motorcycles in Motor Vehicle Safety Standard No. 205 (S5.1.2.1 and S5.1.2.2). We interpret the phrase "lowest seating position" to mean the lowest point on the uncompressed seating surface of the motorcycle operator's seat. I regret that our earlier letter omitted this information. |

ID: nht74-2.32OpenDATE: 02/06/74 FROM: AUTHOR UNAVAILABLE; Richard B. Dyson; NHTSA TO: Kar-Kraft, Inc. COPYEE: PESKOE; COMPTON TITLE: FMVSS INTERPRETATION TEXT: This is in reply to your letter dated December 6, 1973, in which you ask whether there is a distinction between the reference to the "lowest seating position" for motorcycles in S5.1.2.1 of Motor Vehicle Safety Standard No. 205, and the reference to "lowest seating surface" in proposed "Fields of Direct View" (Docket No. 70-7; Notice 2; 37 FR 7210, April 12, 1972). You also request an explanation for the difference between the reference to 15 inches above the seating surface in Standard No. 205, and 18 inches in Docket No. 70-7. The notice in Docket No. 70-7, as you may know, has been withdrawn (38 FR 6194, March 7, 1973). However, we would consider the phrase "lowest seating position" to be synonymous with "lowest seating surface" with respect to these particular items. The 18-inch requirement proposed in Docket No. 70-7 represented a more recent evaluation than the 15-inch requirement in Standard No. 105 of the minimum desirable area for motorcycle visibility. Had that requirement become effective the agency would have taken steps to ensure that the requirements were consistent with each other. Yours truly, ATTACH. December 6, 1973 Richard B. Dyson -- Office of the Chief Council, N. H. T. S. A. Dear Mr. Dyson: In a recent conversation with your Mr. Peskoe, I asked a question relative to FMVSS 205 which Mr. Peskoe advised would best be asked in written form to which your office would make a prompt reply. Accordingly, my question is this: In FMVSS 205, Glazing Materials, at S5.1.2.1 "Safety plastic materials . . . may be used in a motor vehicle only in the following specific location at levels not requisite for driving visibility. (b) Motorcycle windscreens below the intersection of a horizontal plane 15 inches vertically above the lowest seating position." Additionally, in Docket 70-7, Notice 2, Paragraph S10.1 it says: "There shall be no obstructions forward of the forwardmost point of the driver's seat that are above a horizontal plane 18 inches above the lowest seating surface of the driver's seat . . ." Specifically, what is the definition of the "lowest seating position" in FMVSS 205 and lowest seating surface in Docket 70-7 and what accounts for the difference in the 15 inch and 18 inch dimensions? We look forward to your prompt reply in this matter. Sincerely, KAR-KRAFT, INC.; L. A. Volberding -- Administrative Manager |

ID: nht74-2.33OpenDATE: 08/26/74 FROM: AUTHOR UNAVAILABLE; Richard B. Dyson; NHTSA TO: E.I. DuPont de Nemours & Company, Incorporated TITLE: FMVSS INTERPRETATION TEXT: This is in reply to your letter of August 2, 1974, asking for the appropriate method for bending plastic material over the mandrel as specified in Test No. 22 of ANS Z26.1-1966, which is incorporated into Federal Motor Vehicle Safety Standard No. 205 (49 CFR 571.205). You indicate that the test procedure does not specify either the bending force, or whether mechanical means for bending are allowed. Paragraph 5.22.2 of Test 22 states, in part, as follows: After conditioning, the test specimens shall be immediately bent over a mandrel so that either the entire length of the specimen shall conform to the surface of the mandrel or that it be bent 130 degrees over the mandrel, with the longitudinal axis of the specimen normal to the axis of the mandrel. (emphasis added) As the procedure does not specify the bending force, or the method in which it is to be applied, the NHTSA would consider as appropriate any force or method of application that would permit the plastic to be bent immediately after conditioning. There is nothing to prohibit the use of hand or mechanical pressure, but it must be applied in such a way that an immediate bending takes place. Yours truly, ATTACH. I. DU PONT DE NEMOURS & COMPANY INCORPORATED PLASTICS DEPARTMENT August 2, 1974 Office of Chief Counsel -- National Highway Traffic Safety Administration, Department of Transportation Dear Sir: We manufacture a transparent acrylic safety glazing material, Lucite (register) AR abrasion-resistant sheet. Many of our markets are in the transportation industry, including public buses, people movers, and recreational vehicles. Safety glazing materials must conform to ANSI Z26.1-1966 code for glazing motor vehicles operated on land highways, as required by FMVSS #205. The ANSI Z26.1-1966 code, Item 6, flexible Plastics category, is defined in part by Test No. 22. This test requires that a sample of the plastic be "bent over a mandrel so that either the entire length of the specimen shall conform to the surface of the mandrel or that it be bent 180 degrees over the mandrel." (The diameter of the mandrel being 80 times the sample thickness.) The stated purpose of the test is to determine "satisfactory flexibility". No mention is made of the method or technique used in forcing the plastic to conform to the mandrel. The test does not indicate whether mechanical means are allowed; and, if so, what force. It is my understanding that some independent testing laboratories use hand pressure. Would you please indicate to me what the NHTSA or DOT position is on this test and the test method to be used Thank you. Sincerely, Paul D. Carfagna -- Technical Representative, Lucite (register) AR Marketing |

ID: nht74-2.34OpenDATE: 02/15/74 FROM: AUTHOR UNAVAILABLE; Richard B. Dyson; NHTSA TO: Busby Rivkin Sherman Levy and Rehm TITLE: FMVSS INTERPRETATION TEXT: This is in reply to your letter of December 13, 1973, asking whether glazing in the rear quarter windows of the Datsun model HLB-210 may, consistently with Motor Vehicle Safety Standard No. 205, be manufactured of AS 3 glazing material. This depends, as you point out, on whether this glazing is used "at levels requisite for driving visibility" under American National Standards Institute Standard ANS Z26.1-1966, incorporated into Standard No. 205. You refer in your letter to section 1017(a) of the California Vehicle Code which states: Side windows to the rear of the driver and the rear windows not used for vision directly to the rear are not considered areas requisite for driving visibility. The locations where the use of AS 3 glazing is permitted are set forth on page 12 of ANS Z26. AS 3 glazing may be used, "anywhere in a motor vehicle except in passenger car windshields and in the following locations at levels requisite for driving visibility . . . . (2) Passenger automobiles and taxicabs. Glazing of all windows including rear window, all interior partitions, and all apertures created for window purpose. (emphasis added) The only exclusion from the broad prohibition against the use of AS3 glazing in passenger cars is "at levels not requisite for driving visibility." We do not agree with the California Code provision. We consider the word "levels" in Standard 205 to mean vertical heights in relation to the driver's eyes. We, therefore, cannot concur in the application of the "levels requisite for driving visibility" concept as it appears in Standard No. 205 to complete windows or other glazing areas of passenger cars. With respect to the Datsun model in question, there is no evidence in your letter that the windows in question are not at a level requisite for driving visibility. In fact, they appear to include levels of a driver's normal eye point. The NHTSA presently hopes to publish a revised notice of proposed rulemaking regarding direct fields of view in the fall of 1974. Previous proposals regarding this subject were withdrawn by notice published March 7, 1973 (38 FR 6194). Yours truly, ATTACH. December 13, 1973 Guy Hunter -- Motor Vehicle Programs, National Highway Traffic Safety Administration Dear Mr. Hunter: This will confirm our conversation of December 7, 1973 relative to the specification of "levels requisite for driver vision" in the ANSI Standard referenced in Federal Motor Vehicle Safety Standard No. 205. Specifically, we would like your assurance that the guidance provided in the enclosed California Highway Patrol Regulations is in agreement with your interpretation of the Federal Motor Vehicle Safety Standard requirements. As marked, the California regulations permit the use of AS-3 glass in side windows to the rear of the driver (rear quarter windows). Further, we would appreciate any indication from you regarding the timing of the proposed rule making on "direct fields of view", which we presume would establish precise future requirements for the location and light transmittance of motor vehicle glazing. Our interest in this matter arises from the newly introduced model Datsun HLB-210 of our client, Nissan Motor Company. This vehicle has a small fixed pane of AS-3 glazing in what would otherwise be a solid rear quarter panel. I am enclosing a picture of this vehicle. Respectfully submitted, BUSBY RIVKIN SHERMAN LEVY and REHM; George C. Nield -- Engineering Advisor Enclosures STATE OF CALIFORNIA DEPARTMENT OF CALIFORNIA HIGHWAY PATROL P. O.

The following examples illustrate acceptable format: (Graphics omitted) (c) Shaded Areas. Shaded areas of less than 70 percent light transmittance which adjoin areas of 70 percent or more light transmittance shall be marked "AVS1" or "AIllegibleS2" at the dividing line. The arrow shall indicate which portion of the material complies with the item number shown. (d) Size of Markings. The markings required in subsections (a) and (c) shall be in letters and numbers at least 0.070 inch in height. Additional markings may be of any height, shall be immediately above the required markings, and may be changed without notification to the department provided no change is made in the glazing material. 1015. Applicable Safety Glazing Material Standards. Safety glazing material shall meet Federal Motor Vehicle Safety Standard No. 205 and requirements of ANSI Standard Z26.1-1966. 1016. Electrical Conductors. Heating elements used for doing fogging and deicing, and wire and printed conductors used for other purposes manufactured in safety glazing material are acceptable for use in areas requisite for driving visibility in accordance with the following guidelines: (a) Wire and Printed Conductors in Material Marked AS1. Heated wire conductors in material marked AS1 should not exceed 0.001 inch in diameter, should not be spaced closer than 0.040 inch or further apart than 0.150 inch, and the bus bar which connects the ends should be within 0.5 inch of the periphery of the daylight opening. The diameter of conductors used for other purposes should not exceed 0.010 inch for wire or 0.020 inch in width for printed types. Only one such conductor should be placed within 2 inches of and generally parallel to the periphery of the daylight opening; and not more than two should be centered vertically in the glazing material and spaced not more than 2 inches apart. (b) Wire Conductors in Material Marked AS2. Wire conductors in material marked ASE should either meet A31 requirements in preceding subsection (a), or they should not exceed 0.0015 inch in diameter nor be spaced closer than 0.080 inch. The bus bar connecting the ends of the conductors should be within 0.5 inch of the periphery of the daylight opening. (c) Printed Conductors on Material Marked AS2. Printed conductors on glazing material marked AS2 should not be more than 0.040 inch in width nor spaced closer than 0.900 inch. The bus bar connecting the ends of the conductors should be within 0.5 inch of the periphery of the daylight opening. 1017 Determination of Areas Regisite for Driving Visibility. The following methods for determining the levels of glazed areas requisite for driving visibility are recommended and considered acceptable until such time as a Federal Motor Vehicle Safety Standard defining the levels becomes effective: (a) Levels. The established levels requisite for driving visibility include all levels below a horizontal plane 28 inches above the undepressed driver's seat for passenger cars, and 30 1/2 inches for other motor vehicles, except as specified in following subsections (b), (c), and (d). Measurements are made from a point 5.0 inches ahead of the bottom of the backrest and directly behind the center of the steering wheel, with the driver's seat in the rearmost and lowest position and the vehicle on a level surface. Areas requisite for driving visibility include all glazed areas below this plane and all of the glazed area of windows capable of being lowered. Side windows to the rear of the driver and the rear windows not used for vision directly to the rear are not considered areas requisite for driving visibility. (b) Special Vehicles. Corresponding eye heights, based upon an average seat depression of 3.3 inches for passenger cars and 2.0 inches for other vehicles, apply to specially designed vehicles or vehicles designed for a standing driver. (c) Curved Windshields. In order to accommodate manufacturing procedures for curved windshields, it is permissible for shaded windshield glazing material to have less than 70 percent luminous transmittance over areas extending inward from each corner post for a distance not exceeding 10 percent of the windshield width. These areas of reduced luminous transmittance should not extend more than 1.5 inches below the level requisite for driving visibility. The curved windshield exceptions should not apply to motor vehicles manufactured after September 1, 1972. (d) Motorcycles. The established levels requisite for driving visibility for motorcycles include all planes between a horizontal plane 15 inches above the lowest portion of the seat when the seat is depressed by the operator and a horizontal plane 31 inches above the undepressed seat. 1018. Locations of Safety Glazing Material. Safety glazing material shall be used in accordance with the "AS" number marked on the material as follows: (a) AS1. Laminated safety glass marked AS1 is required to be used in the windshield of every motor vehicle except a motorcycle and is acceptable for use anywhere in motor vehicles and campers. (b) AS2 and AS3. Laminated or tempered safety glass marked AS2 is acceptable for use anywhere in a motor vehicle except in the windshield, and anywhere in a camper. Material marked AS3 has less than 70 percent light transmittance and is acceptable only in areas not requisite for driving visibility. (c) AS2-26 and AS3-26. Laminated safety glass marked AS2-26 is acceptable for use anywhere in a motor vehicle except the windshield, and anywhere in a camper. Material marked AS3-26 has less than 70 percent light transmittance and is acceptable only in areas not requisite for driving visibility. (d) AS4 and AS5. Rigid plastic safety glazing material marked AS4 is acceptable for use in interior partitions, auxiliary wind deflectors, folding doors, standee windows in buses, flexible curtains, readily removable windows, openings in roofs, rear windows of soft tops, rear doors of taxicabs, and windows of campers. Material marked AS5 has less than 70 percent light transmittance and is acceptable only in areas not requisite for driving visibility. (e) AS6 and AS7. Flexible plastic safety glazing material marked AS6 is acceptable for use in the rear windows of soft tops, windshields for motorcycles, flexible curtains, and readily removable windows. Material marked AS7 has less than 70 percent light transmittance and is acceptable only in areas not requisite for driving visibility. (f) AS8 and AS9. Wire glass marked AS8 is acceptable for use in folding doors, standee and rearmost windows in buses, and windows to the rear of the driver in trucks and truck tractors. Material marked AS9 has less than 70 percent light transmittance and is acceptable only in areas not requisite for driving visibility. (g) AS10 and AS11. Laminated safety glazing material marked AS10 or AS11 is for use only in armored cars for which permits have been issued under Section 21713 of the Vehicle Code. Bullet-resistant glass marked AS10 is required in the windshields and is acceptable for use anywhere in the vehicle. Bullet-resistant glass marked AS11 is acceptable for use anywhere in the vehicle except the windshield. (h) Shaded Material. The dividing line in the "AVS1" or "AVS2" markings on shaded glazing material shall be located so that the darker side of the dividing line is outside the areas requisite for driving visibility. This order shall take effect on September 1, 1970, as provided in Section 11422(d) of the Government Code. Dated: July 22, 1970 DEPARTMENT OF THE CALIFORNIA HIGHWAY PATROL; A. E. SHAFFER, Captain -- Acting Commander Safety Services Division |

ID: nht74-2.35OpenDATE: 07/30/74 FROM: AUTHOR UNAVAILABLE; Richard B. Dyson; NHTSA TO: Excel Industries TITLE: FMVSS INTERPRETATION TEXT: This is in reply to your letter of June 28, 1974, requesting the status of a proposed amendment published January 9, 1971 (36 F.R. 327), to Motor Vehicle Safety Standard No. 205, "Glazing Materials," that would have required markings specified for windshields to appear in each windshield's lower left-hand corner. This proposed requirement was not adopted. Other requirements proposed by this notice, however, were adopted by a subsequent notice published June 21, 1972 (37 F.R. 12237), which amended Standard No. 205. The preamble of this notice referred to the agency's action on the proposed requirements for marking location. A further notice was issued on November 11, 1972 (37 F.R. 24035), which responded to petitions for reconsideration of the amendments of June 21, 1972. Copies of the notices of June 21 and November 11, 1972, are enclosed. There are presently no requirements regarding the location of markings for motor vehicle glazing materials. Yours truly, ATTACH. June 28, 1974 Lawrence Schneider -- National Highway Traffic Safety Administration Dear Mr. Schneider: On January 9, 1971, page 327 of volume 36, #6 of the Federal Register, a proposed amendment was made to FMVSS#205 at the request of the California Highway Patrol to the effect that after installation of the glazing material in the vehicle, the markings are required to be visible in the lower left corner of each windshield and either the lower left or lower right corner of any other window. As a manufacturer of windshields and side windows for the recreational vehicle industry, particularly motor homes, we have been trying to comply with this proposed standard by adding two trade marks to our windshields so that in a two part windshield, the glass could be used on either side of the vehicle and still comply; however, in reviewing the Federal Register, we find that no follow-up amendments to the safety standard reflect this change. With the cost of materials increasing daily, and the fact that we are paying a premium for this added marking, we are going to discontinue this practice since Mr. Douglas Delve of the Department of Transportation has confirmed that this legislation has never been effected. I would like a written confirmation that this pending legislation is either still pending or has been dropped, so that we may proceed with production without any further concern regarding the compliance to the standards. Very truly yours, Steve A. Spretnjak -- Chief Design Engineer EXCEL INDUSTRIES |

ID: nht74-2.36OpenDATE: 05/06/74 FROM: AUTHOR UNAVAILABLE; Richard B. Dyson; NHTSA TO: Questor Juvenile Products Company TITLE: FMVSS INTERPRETATION TEXT: This responds to your April 9, 1974, petition to substitute the proposed performance requirements for child harness testing under Standard No. 213, Child seating systems, for the performance requirements of Standard No. 209, Seat belt assemblies, to which Questor's Model 275 child harness is presently subject. As reasons for the substitution, you cite the inappropriateness of attachment hardware requirements (S4.3(c)) and the configuration of the test device (Figure 7) of Standard No. 209 as well as the desirability of testing to dynamic performance requirements which may become a part of Standard No. 213. The Standard No. 213 dynamic test values which you recommend are only proposals at this time. Interested parties have not had a full opportunity to comment on them and the NHTSA has not, of course, had the opportunity to fully evaluate them. For these reasons your petition to substitute these new dynamic tests for the Standard No. 209 static tests is denied. You state that testing of the Model 275 to the assembly performance requirements of Standard No. 209 (S4.4(c)) is complicated by the configuration of the test device for Type III harnesses, which is not suited to test a child harness such as the Questor No. 275 that utilizes the adult front lap belts and the rear adult lap belt or the package shelf as attachment points. Paragraph S5.3(c)(2) of Standard No. 209 directs that in such a case "attachment shall be . . . in accordance with the [manufacturer's] installation instructions". As adherence to Model 275 installation instructions requires a front and rear adult belt installation (and in some cases a package shelf) the use of an actual vehicle bench seat in a passenger car would be an appropriate method to evaluate the assembly under S4.4(c) of Standard No. 209. Moreover, because the 12-inch extension requirement for an assembly tested under S4.4(c) is based on zero deflection of the test device, the actual vehicle seat should be modified to eliminate deflection. The NHTSA has previously determined that the requirements of S4.3(c) of Standard No. 209 do not apply to bolts used to secure an adult upper torso restraint, other than the continuous loop type. Similarly, we interpret this provision not apply to the child harness upper torso restraint described in your letter. The bolts would be regulated with respect to strength only by the assembly performance requirements of S4.4(c). Yours truly, ATTACH. April 9, 1974 Richard B. Dyson -- Office of Chief Counsel, National Highway Traffic Safety Administration Dear Mr. Dyson: Questor Corporation has recently developed a novel child restraint harness that is to be marketed under the brand name "Infanseat Model 275 Child Restraint Harness." This restraint system has been under development for over two years to provide maximum dynamic performance at least possible cost to the consumer. The Infanseat Model 275 Child Restraint Harness has closely approached the dynamic performance objectives proposed by the DOT to be effective September 1, 1975. When tested with a standard Sierra three-year-old child dummy, this restraint limited head excursion to 18.8 inches in a 30 mph frontal barrier impact test. Additional improvements in design have been made which will further reduce head excursion. The unique design characteristics of this harness, which provide exceptional dynamic performance, also present difficulties in determining its compliance with FMVSS 209 for Type 3 seat belt assemblies. These problems were discussed with Messrs. R. Jasinski, J. Gilkey, T. Herlihy, and M. Peskoe during a personal visit to Washington on April 4. Mr. Jasinski also reviewed the situation in a phone conversation with Mr. R. Hitchcock. It was suggested after these conversations that this letter be written to you, outlining the areas of concern relative to FMVSS 209. The design of Infanseat Model 275 Child Restraint Harness departs radically from child harnesses commercially available to date. Current harnesses require mounting to the floor of the automobile to restrain the child and vehicle seat back from movement during impact or load. Inasmuch as this floor anchorage could inadvertently be used by the present automobile owner or subsequent owners for an adult lap belt attachment point, it is understandable that FMVSS 209 would require the strength of this anchorage to be no less than 5,000 pounds, paragraph S4.3 (c) (1). It is further recognized that currently available child harnesses loop over the adult backrest of automobiles, prior to being themselves anchored to the vehicle floor, and thus largely rely upon the strength of the automobile backrest to reduce movement of the child in an accident situation and/or also restrain the backrest. The assembly performance criteria of FMVSS 209 paragraphs S5.3 (c) (1) through (4) provide some degree of simulating this installation, and yet the force requirement that the complete assembly is required to withstand is 2,000 pounds, 100 per cent greater than the force requirements of FMVSS 213. The Model 275 Child Harness is shown in accompanying Figures 1 and 2. The significant differences in its installation when compared with existing harnesses are readily apparent. Firstly, an adult lap belt is used to position the lower portion of the child's harness both laterally and forwardly. Secondly, a back strap, or upper tie-down, connects the child harness at the shoulder strap area to either a rear seat adult lap belt for a front seat installation (Figure 1) in an automobile or to a supplementary anchor installed in the metal portion of the panel between the seat back and the rear window for rear seat installation (Figure 2). Neither the front nor rear seat installations require changes or additions to anchorages at the vehicle floor. The viability of the upper tie-down attachment has been dynamically demonstrated by a well-known child seating restraint system that not only must restrain the child but also the child seating system itself. The upper tie-down strap most nearly approximates the function of an adult shoulder strap; that is, it keeps the upper torso from pivoting forward in a frontal impact. FMVSS 209 does not specify minimum force requirements for either Type 2, Type 2a, or Type 3 upper torso restraint attachment hardware. It is suggested, therefore, that the requirements within FMVSS 209 for attachment hardware are neither clear nor appropriate for the Infanseat harness. In addition, the test method for assembly performance does not provide for the recommended installation of this product. While attempts could be made to modify the simulated seat back shown in Figure 7 of FMVSS 209 to provide for the installation of the Infanseat harness, it is felt that any modification will not adequately reporduce the distribution of forces encountered in real-world situations. Also, any approved simulated static load test of a complete assembly at this time is not felt to be appropriate with dynamic testing of child harnesses soon to be required. It is respectfully suggested that rather than subject the DOT to possible adverse public criticism by requesting another static test to determine the adequacy of the complete Infanseat harness assembly, it be excluded from the attachment hardware and complete assembly requirements of FMVSS 209. In lieu of these requirements, the Infanseat harness should be required to prevent head excursion of a Sierra three-year-old test device beyond 18 inches in a simulated 30 mph frontal impact test. The Infanseat harness would thus be required to meet the DOT's proposed dynamic performance requirements for child restraints. Data substantiating the dynamic performance of the Infanseat harness has been independently verified by tests conducted for Consumers Union on prototype harnesses. These tests were not published by CU because the harnesses were not available commercially when their magazine went to press. Additional tests have been conducted to determine the suitability of various materials, installations, and test devices. Significant improvements to the harness are expected to be made, such that it appears likely in the very near future to provide dynamic protection for six-year-old children within the proposed excursion limits desired by the DOT. As important as the Infanseat harness's dynamic performance is its expected retail selling price. The DOT and child restraint manufacturers are equally concerned that children's restraint devices be affordable by the largest possible segment of the public. It is recognized that the purchase and, therefore, the eventual use of children's restraints are directly related to their cost. The Infanseat harness is expected to be marketed at one-half to one-third of the price of existing restraint systems. Thank you for your attention to this request for revised interim requirements that would be applicable to the Infanseat harness, and your early response shall be greatly appreciated. It is understood that this product would automatically be required to comply with the proposed revisions to FMVSS 213 when they become effective.

ID: MULTISTG.UPSOpenMr. Thomas S. Klingman Dear Mr. Klingman: This is in response to your letter dated January 26, 1996, in which you requested that this office clarify which party is responsible for odometer disclosure under Federal law when the disclosure involves a vehicle manufactured in two or more stages. Your letter states that United Parcel Service (UPS) has encountered differing interpretations from several jurisdictions when it registers these vehicles. Under the Federal odometer law, it is the person transferring ownership of a motor vehicle who is obliged to disclose the odometer reading under Federal law. 49 U.S.C. 32705; 49 CFR 580.5(c). Accordingly, the answer to your question of whether it is the incomplete vehicle manufacturer or the final-stage manufacturer that must disclose the mileage on the odometer hinges on the meaning of the terms "transferor" and "motor vehicle" as applied to the Federal odometer disclosure requirements. Section 32702(8) of Title 49 of the United States Code states that "transfer" of a motor vehicle means "to change ownership by sale, gift, or other means." In its implementing regulations, NHTSA has defined "transferor" as "any person who transfers ownership of a motor vehicle by sale, gift, or any means other than the creation of a security interest." Under Part C of Subtitle VI of Title 49 of the United States Code, the definition of "motor vehicle" that applies to the Federal odometer law is: . . . a vehicle driven or drawn by mechanical power and manufactured primarily for use on public streets, roads and highways, but does not include a vehicle operated only on a rail line. 49 U.S.C. 32101(7). According to your letter, UPS purchases the chassis of its vehicles from various chassis manufacturers, and then the chassis is shipped to a body manufacturer, which installs the body on the chassis. The body manufacturer never obtains ownership of the chassis. Accordingly, the only transfer of ownership that takes place between the body manufacturer and UPS is the sale of the body to UPS. This is not a transfer of ownership of a motor vehicle as that term is defined for purposes of the Federal odometer law, because the body alone is not "driven or drawn by mechanical power." This interpretation is also supported by NHTSA's regulation, which exempts vehicles that are not self-propelled from the odometer disclosure requirements of 49 CAR Part 580. 49 CAR 580.6(a)(2). From the outset, NHTSA has exempted transfers of such vehicles from the odometer disclosure requirements because it determined that for this category of vehicles, odometer mileage is not used as a guide for value, because most non-self-propelled vehicles lack an odometer. 38 Fed. Reg. 2978-79 (Jan. 31, 1973). Therefore, the states that require odometer disclosure when the chassis is transferred from the chassis manufacturer to UPS are following the correct procedure under Federal odometer law. Any state that does not require disclosure for that transfer is not following the correct procedure under Federal law. Federal law does not require any odometer disclosure at the time that the body manufacturer transfers ownership of the body to UPS. A state may on its own decide to impose this as an additional requirement to register the vehicle, but it is not a requirement of the Federal law, and such a disclosure would not have to comply with the Federal regulations governing odometer disclosure statements. I hope this interpretation is responsive to your request. If you have further questions concerning interpretation of the Federal odometer statute and regulations, please contact Eileen Leahy, an attorney on my staff, at the above address, or at (202) 366-5263. Sincerely, Samuel J. Dubbin Chief Counsel ref:580 d:3/21/96 |

ID: mvaltr.etlOpen BY TELEFAX Mr. John H. Strandquist Dear Mr. Strandquist: I have received a copy of the Issue Alert dated April 17, 1997, that you sent to the members of the American Association of Motor Vehicle Administrators concerning the decision of the United States Court of Appeals for the Seventh Circuit in Diersen v. Chicago Car Exchange, 110 F.3d 481 (7th Cir. 1997). In that decision, issued on March 31, 1997, the court held that the NHTSA regulation that exempts vehicles ten years old and older from the requirement in 49 U.S.C. Chapter 327 that an odometer disclosure statement be completed when ownership of the vehicle is transferred (49 CFR 580.6(a)(3)) is invalid because Chapter 327 does not authorize exemptions from that requirement. Your Issue Alert noted that you had contacted NHTSA "to determine whether any action is planned to amend the current legislation for odometer disclosure requirements" in light of the Diersen decision. NHTSA has concluded that amending legislation is unnecessary because Congress has already given the agency the authority to exempt vehicles from the disclosure requirements of Chapter 327. Specifically, in section 332 of the FY 1997 Department of Transportation and Related Agencies Appropriations Act, Pub. Law 104-205 (Sept. 30, 1996), Congress provided that "notwithstanding any other provisions of law, the Secretary may use funds appropriated under this Act, or any other subsequent Act, to administer and implement the exemption provisions of 49 CFR 580.6 and to adopt or amend exemptions from the disclosure requirements for any class or category of vehicles that the Secretary deems appropriate." In light of the fact that Congress has now authorized NHTSA to expend funds to adopt or amend exemptions from the disclosure requirements, the agency has concluded that the most expeditious way to resolve the uncertainty caused by the Diersen decision is to publish a final rule repromulgating all of the exemptions currently contained in 49 CFR 580.6 under the statutory authority of section 332 of P. L. 104-205. Because the current situation can cause problems, such as confusion about whether or not an odometer disclosure statement is required when an older vehicle is transferred, inappropriate rejection of title applications and other delays in the titling process, particularly for vehicles transferred into states within the Seventh Circuit, we plan to make this final rule effective immediately upon publication in the Federal Register. So that your members and others may have prompt access to information about actions NHTSA is taking in response to the Diersen decision, the agency plans to post this letter, the Federal Register notice and any other relevant information on its World Wide Web site, which is accessible on the Internet at http://www.nhtsa.dot.gov/new. We will also provide you with a copy of the Federal Register notice as soon as it is available. I hope this information is helpful. If you have any further questions on this matter, please contact Eileen Leahy, an attorney on my staff, at 202-366-5263. Sincerely, |

ID: myles.ztvOpenMr. Russel Myles Dear Mr. Myles: This is in reply to your letter of March 7, 2003, following up on my letter of May 24, 2002, regarding prepaid mandatory service insurance policies acquired by registered importers. You have two questions related to that letter. Your first question is related to my conclusion that if such a policy becomes ineffective because the underwriter has gone out of business, an RI would not be required to secure a new policy that provides coverage for the periods that remain outstanding on all previously imported vehicles. You asserted that this is contrary to my statement in the letter that "policies must remain in effect until ten years have elapsed from" the date on which the vehicle is first purchased after importation. You asked that I reevaluate this interpretation. Obviously, we hope that the issuer of the mandatory service insurance policy will remain financially able to honor claims against that policy for the full ten years that free remedy of noncompliances and safety-related defects is required. However, as I remarked last year, "the owners of these vehicles would be protected to the extent that the company is required by state regulatory authorities to maintain sufficient reserves or take other measures to cover its outstanding liability on previously issued policies in the event that it should go out of business."At that time, we were unaware that any policy underwriter had gone out of business. You have now brought to our attention one that has: Vehicle Protection Services (VPS) of Michigan. However, you have not indicated that any owner covered by a VPS policy has suffered actual loss as a result thereof, or that Michigan law does not adequately address the issue of reimbursement. As I further noted in 2002, our regulations do not obligate a RI to obtain new policies for previously imported vehicles if the original underwriter goes out of business. For this reason, I cannot provide an interpretation that differs from the one I gave you last year. However, if events transpired that such a requirement would be in the public interest, we could propose an appropriate amendment to our regulations. You have also expressed concern about contracts issued to a RI by a company that is not an insurance carrier but an entity that is only "backed" by an insurance company. Specifically, you asked who has standing "to make a claim on the real insurance policy," commenting that "the insurance companys only obligation is to the non-insurance company issuing the guarantee." It is our understanding that a vehicle owner holding such a policy would present a claim to the non-insurance company which would either pay the claim or present the claim to the insurer for payment, either to the policy holder or the non-insurance company. We adopted these requirements based upon what we understood were the commercial realities of the time, principally the difficulty in finding businesses that would issue service insurance contracts or policies. We noted your statement that "vehicle owners and/or RIs could find themselves facing deductibles and other coverage limitations that completely undermine the regulatory coverage requirements and create other practical difficulties for those persons intended to be protected." However, RIs, as part of the application process, are required to furnish us with a copy of the policies they intend to provide to vehicle owners and are thereafter required to notify us within 30 days of any change in the information that is submitted in its application. See 49 CFR 592.5(a)(8) and (f). RIs are also required to include a current copy of their service insurance policy in their annual applications for renewal. See 49 CFR 592.5(e). We routinely review these policies to ensure they are consistent with the obligation of the RI to provide remedy without charge during the term of the policy. If you have further questions, you may call Taylor Vinson of this Office (202-366-5263). Sincerely, Jacqueline Glassman ref:591 |

ID: NakachiOpen Matthew K. Nakachi, Esq. Dear Mr. Nakachi: This responds to your letters of November 30, 2000 (as supplemented by an email of December 18, 2000, to Taylor Vinson of this Office), and January 3, 2001, concerning the applicability of certain Federal motor vehicle safety standards to sidecars. By way of background information, the National Highway Traffic Safety Administration (NHTSA) has the statutory authority to issue Federal motor vehicle safety standards (FMVSSs) applicable to new motor vehicles and new 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 FMVSSs. (1) The FMVSSs apply in different ways. Some apply only to new motor vehicles, others apply to new items of motor vehicle equipment ("equipment standards"), while others apply to both new vehicles and new equipment. Your letters concern the importation of sidecars which would be sold to individuals who already own motorcycles. These sidecars would not be considered "motor vehicles" but would be considered motor vehicle equipment. (2) Therefore, standards that apply only to new motor vehicles would not apply to these sidecars. However, as discussed below, the sidecars would be subject to certain equipment standards. If an aftermarket sidecar incorporates motor vehicle equipment that is regulated by an equipment standard, the equipment would have to independently comply with the applicable standard. (See NHTSA's May 4, 1982 letter, copy enclosed). Of particular relevance to sidecars are our standards for brake hoses, tires, tire rims and glazing, all of which apply to individual items of equipment. Brake hoses, tires, tire rims and glazing, if provided on a sidecar, must meet the requirements of Standard Nos. 106, 119, 120, and 205, respectively, that apply to equipment for motorcycles. You note, for certain of these standards, that the "scope" sections do not mention sidecars but only include such equipment that is used with "passenger cars, multipurpose passenger vehicles, trucks, buses, trailers, and motorcycles." That the standards do not list sidecars is not of significance, because the lists only include vehicle types, and a sidecar is an accessory item (not a vehicle itself). A sidecar is an accessory for a motorcycle. Therefore, equipment on a sidecar is equipment for use on a motorcycle. To determine whether a standard applies to the equipment on a sidecar, we check the application section of the standard to see whether it applies: (a) to items of motor vehicle equipment, and (b) that is for use in motorcycles. If the answer to both of these is yes, then the equipment on the sidecar would have to comply with the standard. Standard No. 108 In the May 4, 1982, letter we also stated that lighting equipment on a sidecar would have to comply with Standard No. 108. We have reconsidered our views on this issue. Standard No. 108 applies, in relevant part, to certain types of motor vehicles including motorcycles, and to "(l)amps, reflective devices, and associated equipment for replacement of like equipment on vehicles to which this standard applies." Since an aftermarket sidecar is sold as an accessory to a motorcycle and not to replace a part of a motorcycle, any lamps, reflective devices or associated equipment on the sidecar would not be "for replacement of like equipment" on the motorcycle. Therefore, Standard No. 108 would not apply to an aftermarket sidecar. This would be true whether the sidecars were imported as single items or with the sidecar fenders incorporating lighting equipment separated from the rest of the sidecar. However, detached and discrete items of lighting equipment that could be installed either on motor vehicles to which Standard No. 108 applies, or on an aftermarket sidecar, could not be imported unless the items of lighting equipment comply with Standard No. 108. We do not understand that your client intends to import detached items of lighting equipment. Standard No. 119 Our understanding is that the tires of the sidecar are not labeled in any manner. Unlabeled tires would not meet the requirements of Standard No. 119. The marking requirements for tires subject to Standard No. 119, "New pneumatic tires for vehicles other than passenger cars" (49 CFR 571.119), are set forth in paragraph S6.5 of the standard. Paragraph S6.5(b) requires that each tire be marked with "the tire identification required by part 574 of this chapter." Section 574.5, "Tire identification requirements," specifies that "[e]ach tire manufacturer shall conspicuously label on one sidewall of each tire it manufactures, except tires manufactured exclusively for mileage contract purchasers or non-pneumatic tires of non-pneumatic tire assemblies, by permanently molding into or onto the sidewall, in the manner and location specified in Figure 1, a tire identification number (TIN) containing the information set forth in paragraphs (a) through (d) of this section." According to this paragraph, the information must be molded into or onto the sidewalls of the sidecar tires. Of course, the tires would also have to comply with all performance requirements applicable to new motorcycle tires. Standard No. 120 |
