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.

Mr. Don Gerkin Product Engineer Cosco Home Products 2525 State Street Columbus, Indiana 47201

Dear Mr. Gerkin:

This responds to your letter of January 23, 1980, to Mr. Vladislav Radovich concerning Standard No. 213, Child Restraint Systems. Your letter was forwarded to my office for reply.

You asked whether a crotch strap that is "permanently attached to a movable shield can be attached during the 20 mph test required for child restraint systems that have fixed or movable shields. Sections S6.1.2.3.1(c) and S6.1.2.3.2(b) provide that, in the 20 mph tests, the child restraint belts are not to be attached unless "they are an integral part of the fixed or movable shield." The agency used the word "integral" in its ordinary sense to mean something that is "formed as a unit with another part." (Webster's New Collegiate Dictionary, 1977). A crotch strap that is permanently affixed to the shield is formed as a unit with the shield, and therefore, can remain attached during the test.

You also asked, whether, if the movable shield "were designed in such a way that moving it into position for use it automatically locked in that position, and a child was unable to unlock it", would the 20 mph test be conducted with the shield locked into place? Sections S6.1.2.3.1(c) and S6.1.2.3.2(b) provide that each movable surface is to be positioned in accordance with the manufacturer's instructions. Therefore, as long as your instructions explain how to lock the movable shield, it can be locked into place prior to the testing.

If you have any further questions, please let me know.

Sincerely,

Frank Berndt Chief Counsel

RE: (49CFR Part 571) (Docket No. 74-9; Notice 6)

Dear Mr. Radovich:

After reviewing our arm rest model and shield model Child Restraints, it is obvious we can salvage nothing. We must start over with some new concepts.

As there is no time for us to waste, we need the Agency's official answer on some points in order to continue.

1. If a barrier were designed in such a way that the top end of the crotch strap was permanently attached to it. The other end of the strap was removable from its anchorage point below the plastic shell attached to a frame only by removing some hardware that is never intended to be removed as long as the barrier is attached to the child restraint.

Can the 20 MPH test for compliance be conducted with the barrier and crotch strap hooked up as described above?

2. If a barrier were designed in such a way that moving it into position for use it automatically locked in that position, and a child was unable to unlock it. Would the 20 MPH test for compliance be conducted with it locked as described above?

We would appreciate your attention to these points at the earliest moment.

Sincerely,

Don Gerken Product Engineer

TITLE: FMVSS INTERPRETATION

TEXT: This is in reply to your letter of April 14, 1980, asking for a confirmation of your interpretation of Section S4.1.4 of Motor Vehicle Safety Standard No. 108.

This section specifies requirements affecting school bus signal lamps "when the bus entrance door is opened." Blue Bird is designing an additional entrance door for its buses and you interpret S4.1.4 as requiring the same operational characteristics for the new door.

We confirm your interpretation that "entrance door" means any entrance door on the school bus. Obviously the purpose of the requirement is not achieved if it is restricted to the traditional entrance door on the right front side of the bus and excludes any other entrance door.

Thank you for your interest in safety.

SINCERELY,

BLUE BIRD BODY COMPANY

April 14, 1980

Frank Berndt Chief Counsel NHTSA

Dear Mr. Berndt:

SUBJECT: FMVSS 108

Blue Bird Body Company is in the process of designing an entrance door that will be located behind the driver on the left side of school buses. This entrance door will be in addition to the normal right front entrance door and will operate independently.

FMVSS 108 - Lamps, Reflective Devices, and Associated Equipment - Passenger Cars, Multipurpose Passenger Vehicles, Trucks, Buses, Trailers, and Motor-cycles, Section S4.1.4 requires school buses to be equipped with signal lamps that, in addition to other requirements:

"The system shall be wired so that the amber signal lamps are activated only by manual or foot operation, and if activated, are automatically deactivated and the red signal lamps automatically activated when the bus entrance door is opened."

From this statement, we interpret "entrance door" to mean any and all entrance doors. In the case described above, we interpret the standard as requiring the same operational characteristics of both the normal right front entrance door and the new left side entrance with regard to activation and deactivation of signal lamps. This letter seeks confirmation of this interpretation. Your early response will be apprecated.

Thank you!

TEXT: This is in response to your letter of April 3, 1980, requesting confirmation of the applicability of S4.4 of Federal Motor Vehicle Safety Standard No. 115 (49 CFR 571.115) solely to light trucks and passenger cars.

Although Standard No. 115 applies to a variety of vehicle types, including multipurpose passenger vehicles, the location requirement in S4.4 regarding the placement of the vehicle identification number is of more limited applicability. The section expressly provides that the requirement applies to passenger cars and to trucks with a gross vehicle weight rating (GVWR) of 10,000 pounds or less only. Since Standard No. 115 does not contain any other VIN location requirement, manufacturers of multi-purpose passenger vehicle, buses, trailers, incomplete vehicles, and heavy trucks are not limited by that standard in their choice of a VIN location. For definitions of these vehicle types, see 49 CFR 571.3.

SUBJECT: Applicability of FMVSS115, S4.4

Dear Mr. Schwartz:

This letter will confirm a telephone conversation of February 13, 1980 between Mr. R. C. Hamilton and yourself regarding the applicability of FMVSS 115 paragraph S4.4 to Multi Purpose Vehicles. Mr. Hamilton was advised of the following:

S4.4 does not apply to MPV's or vans. Further, the NHTSA had not intended for MPV's or vans to meet the requirement that the VIN be readable through the windshield glass from a point outside the vehicle. As written S4.4 is applicable only to passenger cars and light trucks with a GVWR of 10,000 pounds or less. The above represents our understanding of the applicability of S4.4 of FMVSS 115.

Re: FMVSS-115 VIN Requirement

Dear Mr. Schwartz:

The following is my understanding of the new VIN requirement, as it will be implemented by Miller Tilt-Top Trailer:

- To be supplied by S.A.E.

- Series of trailer (i.e. "OT").

- Length of platform to nearest foot (i.e. "20"). *

- Number of axles (i.e. "4").

- Check digit (calculated per S5.1).

- Model year (i.e. "A" for 1980).

- Plant of manufacture (i.e. "M" for Milwaukee).

- Sequential number assigned by Miller Trailer

* - All trailers that we manufacture have a rectangular, flat platform which should satisfy the "Type of Trailer" and "Body Type" information requirements.

Does all of this information meet with D.O.T. approval?

MAY 7 1980

Mr. Samuel W. Halper Bartmen, Braun & Halper Attorneys at Law 1880 Century Park East, Suite 1015 Los Angeles, California 90067

Dear Mr. Halper:

This responds to your letter of March 13, 1980, asking several questions about Standard No. 213, Child Restraint Systems, on behalf of California Strolee, Inc.

I would first like to correct an apparent misunderstanding you have about remarks made by Mr. Hitchcock in a meeting with you and Mr. Richard Hyde of Strolee. Mr. Hitchcock's remarks were to the effect that the agency encouraged beneficial innovations in child restraints and would be receptive to amending the standard to remove any restrictions to beneficial innovations. Any amendments to the standard would be made in accordance with the requirements of the Administrative Procedures Act. The agency does not engage in "ad hoc" rulemaking procedures.

The following are the responses to the fourteen questions you asked.

1. You asked how the minimum surface area requirements set in section 5.2.2 for the sides and back of child restraints are to be measured. You were specifically concerned about measuring "curved surfaces, without some guidelines, the exact place where the side stops and the back begins cannot be ascertained." The area's measurements can be determined by positioning the appropriate test dummy in the restraint. The area within the dummy's outline projected directly rearward and the areas within the dummy's torso outline projected directly sideward must comply with the minimum surface area for the back and sides of the restraint.

2. You are correct that section S5.2.2.1(c) only requires a minimum radius of curvature and does not establish a minimum surface area for fixed or movable surfaces in front of the child. The agency encourages manufacturers to utilize designs with large surface areas at least equivalent to the shield designs incorporated in some current restraints.

3. You asked whether shoulder belt grommets are prohibited by section 5.2.3.2. In response to Strolee's petition for rulemaking on section 5.2.3.2, the agency has amended the section to permit the use of grommets that comply with the protrusion limitation requirements of section 5.2.4.

4. You raised a question about whether section 5.4.3.3 requires the use of a five-point belt system. The agency's intent was to allow the use of hybrid systems, which for example, might use upper torso restraints, a crotch strap and a shield instead of a lap belt. Thus, the agency provided in section 5.4.3.3(c) that a crotch strap must connect to the "lap belt or other device used to restrain the lower torso." The agency established the minimum radius of curvature requirements of section 5.2.2.1(c) to ensure that any surface used in place of a lap or other belt would not concentrate forces on a limited area of the child's body. The recent notice on the standard, appearing in the Federal Register of May 1, 1980, amends the standard to clarify section 5.4.3.3.

5. You objected to the buckle force requirements set in section 5.4.3.5 as being too high. The goal of that section is to prevent young children from opening the buckles while ensuring that adults can do so. As explained in the December 1979 final rule, section 5.4.3.4 is based on research done by the National Swedish Road and Traffic Institute. The research showed that young children could not open a buckle requiring a release force of 12 or more pounds, but could open buckles requiring a lower release force. That same research found that buckles requiring a release force greater than 20 pounds would be difficult for adult women to open. The agency is not aware of any research contradicting the Swedish study and no commenter to the docket submitted any data showing that the Swedish study is inaccurate.

6. You asked for an interpretation of the words "integral" and "position" as those words are used in section 6.1.2.3.1(c) and 6.1.2.3.2(c). Amended Standard 213 is intended to address, among other things, the problem of misuse of child restraints. The principal misuse involves the failure to attach buckles and latches. To ensure that children using child restraints are afforded protection notwithstanding such misuse, the standard specifies that the belts are to be attached to restraining shields during testing only if they are integral parts of the shields. Webster's New Collegiate Dictionary (1977) defines "integral" as meaning "formed as a unit with another part." Attachment of belts that are integral parts is permitted since they are intended to remain attached whether or not the restraint is in use and thus are not subject to the type of misuse described above.

The word "position" was also used in its common dictionary sense to mean put in place or arrange. Thus during the test, each movable surface will be put into place in accordance with the manufacturer's instruction. The positioning requirements only apply to the arrangement of the movable surface and does not permit the attachment of any belts that are not an integral part of the movable surface.

7. You stated section 6.1.2.4 is inconsistent with S6.1.2.3.1 and 6.1.2.3.2 because 6.1.2.4 supposedly allows attachment of the restraint system's belts, while sections 6.1.2.3.1 and 6.1.2.3.2 do not allow belts to be attached that are not an integral part of a fixed or movable surface.

Your interpretation is not correct. Section 6.1.2.4 sets specifications for tightening the restraint system's belts, prior to the sled test. However, both sections 6.1.2.3.1 and 6.1.2.3.2 provide that the belt adjustment requirements of section 6.1.2.4 are not to apply to belts that are not an integral part of the fixed or movable surface.

8. You asked how the agency defined "target point" as that term is used in section 5.1.3.2. Section 5.1.3.2 requires that "no portion of the target point on either side of the dummy's head" shall pass through two specified planes during the sled test. The agency used the term "target point" to refer to the center of the target on the side of the test dummy's head. The location of the target is specified in the engineering drawing incorporated in Part 572, Anthropomorphic Test Dummies, Subpart C.

9. You asked whether the standard establishes strength specifications for belts. Section 5.4 establishes performance requirements that the belt systems used in child restraint systems must meet. The section does not establish specific breaking strengths for the belts, other than the requirement in section 5.4.1(a) that after being subjected to "the abrasion requirements of Standard No. 209, Seat Belt Assemblies, the belts must have a breaking strength of not less than 75 percent of the strength of the unabraided webbing...." Of course, belts which are to be attached during testing must not break during the test if the effect of the breakage is to cause a violation of section 5.1.2 and 5.1.3.

10. You expressed concern about "the difficulty in running quality control tests where the buckle hardware is not subject to specifications, but only performance standards."

The National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1391) only authorizes the agency to issue requirements that are as performance oriented as possible. The Act places responsibility on a manufacturer to devise its own specifications which will ensure that its product performs as required.

11. You asked our opinion whether the Waterbury buckle complies with standard No. 213. The agency does not issue opinions as to whether a particular design does or does not comply with the requirements of a standard. Under section 114 of the Vehicle Safety Act, manufacturers must certify that they comply with all applicable federal standards. 12. We have answered your questions concerning the use of soft foam armrests or trays in our earlier letter of April 17, 1980.

13. You asked whether "a buckle affixing the crotch strap to some other portion of the car seat must comply with the tension (sic) requirements of section 5.4.3.5. That section provides that "Any buckle in a child restraint system belt assembly designed to restrain a child using the system shall" meet specified buckle release requirements. Since a crotch strap is used in a child restraint system to restrain the child, a buckle used with the crotch strap must comply with the requirements of section 5.4.3.5.

14. You raised a question about the safety of buckles that "do not snap or latch, but rather require the turn of a knob to seal them together." Your concern in that the knob may not be fully turned and thus the buckle may not be fully latched. Any buckle, regardless of its specific design must comply with the release requirements of section 5.4.3.5. In the preamble to the December 1979 final rule, the agency encouraged manufacturers to use push button buckles, similar to those used in automobile belts, so that people unfamiliar with child restraints can readily unbuckle them in emergencies. Use of push button buckles would also solve the potential problems of incomplete latching that may be associated with knob-type buckles.

If you have any additional questions, please let me know.

Sincerely,

Mr. Stephen Oesch Office of the Chief Counsel National Highway Traffic Safety Department of Transportation 100 7th Street, S. W., Room 5219 Washington, D. C. 20590

Re: Standard No. 213, Child Restraint Systems California Strolee, Inc.

Dear Mr. Oesch:

This letter will serve to confirm some of the items that were discussed between Mr. Hyde and me, on behalf of California Strolee, Inc. ("Strolee"), and Mr. Hitchcock, Mr. Radovitch, Dr. Burgett and you in our meeting of last week.

The following summation is presented to you in numerical order, but the relative importance of the item is not to be inferred from its location on the list.

Throughout the meeting we expressed our concern with the vagueness of certain areas of the standard. In addition, we expressed our concern regarding the manner in which this standard will be administered. This concern was further reinforced by our discussion during the first hour with Mr. Hitchcock. Mr. Hitchcock indicated that he would be receptive to any new ideas, and that if the Department felt the idea had merit the standard could be amended or interpreted to reflect these developments. Such an approach, we submit, is contrary to law and places the companies in the industry at a severe competitive disadvantage with each other. While Strolee is earnestly in favor of all developments that will truly enhance child safety, it feels that any developments must be adequately tested, to insure their safety, and must conform to Standard No. 213. If the standard is to be changed, then adequate notice should be given to all manufacturers, adequate time to comment should be given, and the standards duly adopted and published in the Federal Register citing realistic compliance time for the benefit of all manufacturers in the industry. To have "ad hoc" approval would, we feel, be both contrary to law and unfair to the manufacturers who have attempted in good faith to comply with the wording of the standard.

We expressed a concern to you regarding, for example, Section 5.4.3.3, which clearly states that if the child restraint system has belts, it shall have the three types of belts, to wit: shoulder belts, a lap belt and a crotch strap, the latter only if the seating system is recommended for children over twenty pounds. We objected to the Department giving its approval to a car seat having less than this number of belts since the standard expressly requires this. Our reasoning related to the fact that a manufacturer, be it Strolee or some other manufacturer, who relied upon the clear and specific requirements of this section of the standard in designing its car seat could be faced with a situation where a competitive car seat does not contain the required number of belts and was designed in a different manner. The company attempting to comply with the standard could, thus, be discriminated against in favor of another manufacturer who did not comply with this section of the standard. The obvious unfairness of this result, not to mention the questionable legality of such a procedure with amorphous standards, is not subject to dispute. This matter is considered from a different standpoint in the discussion that follows.

One final introductory point, both Mr. Hyde and I expressed our concern with the enforcement date of the new standard. In the realistic world of business, seats must be designed and tested, molds made and tooling prepared for production and then the seats must be retested. Our best estimate is that will take at least six months for the mold alone. Mr. Hyde has presented a letter to you setting forth a realistic time frame. We would earnestly request that the standards not become effective until March 1, 1981. In this regard, if the Department is going to allow amendments to the standard, or interpretations to the standard, to remove some of the ambiguities, we would request that a similar time consideration should be given after the interpretation or the amendment. For example, if Strolee has designed a car seat based upon three types of straps clearly mandated by Section 5.4.3.3 and the Departmental interpretation amends or interprets its standards to say that only two types of straps are required, then in the interest of fairness, we feel sufficient time should be given to allow us to retool, retest and take whatever steps are necessary to bring our seat into conformity with the amended standard. If such is not allowed, as I pointed out to you my client will be at a severe disadvantage or, in the alternative some other manufacturer will be at a severe disadvantage concerning their car seat vis-a-vis the Strolee seat.

In regard to the specific problems that we see with the regulations, while I am aware that the regulations have become final and the time for comment has expired, the following reflects some of the matters that we discussed and some of our concerns:

1) Section 5.2.2. This section fails to indicate how the dimensions of 85 square inches, 24 square inches and 48 square inches are to be measured. When dealing with curved surfaces, without some guide lines, the exact place where the side stops and the back begins cannot be ascertained. It was suggested that, as to the back areas, you were talking about the area directly behind the dummy.

2) Section 5.2.2.1(c). This section requires a radius of curvature of not less than three inches. We inquired as to a minimum area. Although it is certainly not Strolee's intent, or any other manufacturer of which we are aware, it is conceivable that a one-half inch metal bar with a radius of curvature of not less than three inches would pass this standard. Mr. Hitchcock stated that generally a one and one-half inch width, similar to the belt width requirements, would be acceptable, but such does not appear from the regulations.

3) Section 5.2.3.2. It was pointed out to you that this section would preclude the use of a shoulder harness which is inserted through the back of the shell, since the areas where the shoulder strap is inserted would not contain the required material. The Strolee system used grommets. You indicated to us that the grommets will be acceptable provided they comply with the protrusion limitation of Section 5.2.4.

4) Section 5.4.3.3. You indicated to us that there was no reason that a manufacturer cannot use the nonbelt substitute for the required three belt system. You indicated that you would interpret it with a ruling. In this connection, I have already expressed our objection to this type of procedure wherein a ruling would be squarely contrary to the express language of the standard.

5) Section 5.4.35. We raised some objection to the twelve pound--twenty pound standard. Mr. Hyde pointed out the experience that Strolee has had when the tension to release the belt is too tight (Strolee's buckle release force is in the eight pound range). Mr. Radovitch indicated that these standards were adopted from a Swedish study without tests being made by your department. Mr. Hyde pointed out that if the tension is too great, the mother will not use the belt buckle system, and this would not be in the best interest of the child. Strolee's experience has been some complaints by women to an eight pound buckle being difficult to use. If the twelve to twenty pound standard is mandatory, there would be substantial difficulty in removing a child from the car seat under emergency circumstances. We question if there has been any investigation as to the validity of the Swedish study.

6) Sections 6.1.2.3.1(c) and 6.1.2.3.2(c). The question of what is meant by the use of the words "integral part of the system". After substantial discussion, we were advised that the Department considered it as an integral part if it could not be removed without the use of tools. That is, if the belts could be removed by hand, they would not be considered an integral part of the fixed or moveable surface.

We also asked what was meant by the word "position" wherein the standard mandates that you position each moveable surface in accordance with the manufacturers instructions. Does this mean that belts can be attached? I feel this was not clarified or resolved.

7) Section 6.1.2.4. It was pointed out to you an inconsistency of this section with Sections 6.1.2.3.1 and 3.2. Section 6.1.2.4 providing that if the child seat is provided with shoulder and pelvic belts they shall be adjusted accordingly, yet Tests Configuration II precludes the use of such belts.

8) Section 5.1.3.2. We asked for a definition of the words "target point" and you indicated that this was the center point of the target area, not a target area of a fixed diameter.

9) Section 5.4. We asked for confirmation as to strength specification on the belts and hardware. You indicated that there were no specifications, just performance requirements and a minimum width of not less than one and one-half inches on the belts. This included any positioning belt.

10) Section 6.2. We pointed out to you the difficulty in running quality control tests where the buckle hardware is not subject to specifications, but only performance standards. It was impractical, Mr. Hyde stated, to run sled tests on each group of buckles received and while another test might be devised, the realiability of such other test could not be totally insured.

11) We asked your opinion as to whether the Waterbury buckle complies with your requirements. We did not resolve this.

12) We asked your opinion concerning a soft foam arm rest or tray in front of the car seat, something that would contribute play value but obviously having no safety function. We would appreciate your studied opinion on this. Strolee feels such an arm rest is most important to keep the child happy in the car seat.

13) In regard to the crotch strap, we requested an interpretation as to whether a buckle affixing the crotch strap to some other portion of the car seat must comply with the tension requirements of Section 5.4.3.5. We expressed our concern that a child might be able to reach the crotch strap and undo it if the tension requirements were not met.

14) In regard to the buckle system, we expressed our concern as to buckles that did not snap or latch, but rather required the turn of a knob to seal them together. What happens if the knob was not fully turned, i.e., if a bolt restraint was turned half way so that the buckle was not fully latched. You indicated to us that you had not considered that problem.

In addition to the foregoing specifics, we expressed our general concern with this standard and the difficulty of complying with it. We pointed out to you that Strolee is and always has been a conscientious manufacturer of quality products with safety first in mind and has a record for producing a reliable seat without safety complaints. For over twenty-five years, Strolee has studied the buying habits of parents, and more importantly, safety for infants. Thus, their strong belief that this new standard will reduce car seat usage and, most regretably, actually reduces the protection of the infant.

While I did not discuss it with you, I think you should bear in mind that any client, the largest manufacturer of juvenile car seats, has never been sued or had a claim made for even one child that was ever injured in any automobile accident. To the contrary, its files are replete with letters from parents praising Strolee for saving their child from serious injury or worse, in accidents of unbelievable force. In this day and age where individuals are all too willing to file claims and to sue for accidents, the record of Strolee in producing a safety device for children, I believe, is unparalleled. It is this record which makes the new standards so punitive to my client and to parents and their infants. The cost, both in dollars and cents, and in executive time, to change a product where no need has been shown to exist is particularly onerous. Indeed, when one reflects that the added costs necessitated by the changes will result in a higher cost to the consumer, and a subsequent diminution in demand, the new standard seems incongruous.

In conclusion, we request that all ambiguities, to the extent they can be ascertained at the present time, be resolved, that the effective date of the regulations be postponed to March 1, 1981, and if amendments are made to the standard, that the effective date be delayed a proportionately greater length of time. We also request that any amendments be made subject to comment and review by appropriately qualified individuals in the private sector and we request that no competitive advantage be granted to anyone in the industry by virtue of any interpretation of existing standard without due process of law.

Yours very truly,

Honorable Samuel S. Stratton House of Representatives Washington, D.C. 20515

Dear Mr. Stratton:

This responds to your recent correspondence requesting information on behalf of the Schenectady County Traffic Safety Board. The Safety Board is concerned that many new or converted propane-powered vehicles carry no identification indicating that the vehicles contain propane fuel instead of gasoline. The Safety Board states that this creates a dangerous situation for firemen, policemen or other emergency personnel who respond to accidents involving propane-powered vehicles. You were asked to initiate legislative action to require such identification on these vehicles.

The National Highway Traffic Safety Administration issues safety standards and regulations governing the manufacture of new motor vehicles and motor vehicle equipment. Therefore, if there were a demonstrated safety need for identification on propane vehicles, the agency would have authority under the National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1381, et seq.) to require a label or tag as was suggested by the Safety Board. Please inform the Safety Board that it should petition the agency to initiate rulemaking action to establish such a requirement if it has information or evidence indicating that a safety problem does indeed exist. I have enclosed a copy of the regulation which explains what must be included in a Petition for Rulemaking.

The agency has no authority under the Vehicle Safety Act to regulate used motor vehicles and, therefore, could not require an identification label on a used vehicle that is converted to propane fuel. Congress left this jurisdiction to the individual States. Consequently, Congressional action or action at the State level would be required to mandate identification labels on used vehicles.

I am also enclosing a copy of a letter of interpretation the agency issued last August which discusses the implications under Federal law of installing auxiliary fuel tanks in motor vehicles and of converting vehicles to the use of propane gas. Although not directly related to the Safety Board's concern, it might be of interest.

I hope this has been responsive to your inquiry. If you have any further questions, please contact Hugh Oates of my staff at 202-426-2992.

Sincerely,

Frank Berndt Chief Counsel

Dear Congressman Stratton:

The Schenectady County Traffic Safety Board is concerned that many new or converted propane-propelled vehicles carry no indication that these vehicles contain propane fuel tanks.

This lack of information could have very tragic results if a propane-propelled vehicle is involved in an accident or catches on fire. Firemen, policemen, or other emergency personnel responding to the scene will be unaware of the danger presented by the propane fuel tanks and will not take the proper precautions required when working near such a highly volatile substance.

The Traffic Safety Board strongly recommends that new or converted propane-propelled vehicles be clearly marked as carrying propane fuel tanks. The marking should be in a conspicuous location and might be similar to the markings that are currently used on many vehicles to identify them as being diesel-powered or as using only unleaded fuel.

The Traffic Safety Board asks for your help in initiating legislative action on this matter. Please contact us if you have any questions.

Sincerely,

John L. McGovern Chairman

Mr. Ralph F. Lundregan Government Relations Manager Avery International Specialty Materials Division 50-L Edwards Ferry Road Leesburg, Virginia 22075

Dear Mr. Lundregan:

This is in reply to your letter of April 16, 1980, asking whether Motor Vehicle Safety Standard No. 108 allows "reflective markings (such as red diagonal stripes on a white reflective background) to be used to increase visibility on the front of trucks and heavy vehicles".

You are correct that Standard No. 108 does not directly address this question. The section of the standard that appears most pertinent to it, however, is S4.1.3 prohibiting the installation as original equipment of any reflective device "that impairs the effectiveness of lighting equipment required by" Standard No. 108. We would be concerned, for example, if reflective materials were installed in a manner that might cause confusion with headlamps or front turn signal lamps. We also wish to point out that under the standard the use of the color red is at the rear of motor vehicles and that its appearance in any other location might also cause confusion.

However, as a practical matter the use of reflective materials as truck and heavy vehicle equipment sold either as original equipment or in the aftermarket is governed by requirements of the Bureau of Motor Carrier Safety (Federal Highway Administration) which prohibit use of the color red on the front of a vehicle. You should review their requirements before proceeding with your marketing plans. (49 CFR 393.26(e)(4)).

Dear Mr. Wood:

Avery International manufactures self adhesive materials for a wide variety of uses including markings, decals, striping, etc. for various vehicles.

Although our Fasign reflective materials may be used for markings on the side and the rear of trucks and heavy vehicles, a question has been asked on whether similar reflective markings (such as red diagonal stripes on a white reflective background) may be used to increase visibility on the front of such vehicles?

The Federal Motor Vehicle Safety Standard Number 108 on lights and reflective devices does not seem to address this particular question.

Since Avery is in the process of possible marketing for such truck markings, we would appreciate a ruling, interpretation, or reference to something specific regarding this subject.

Thank you for your assistance in this matter.

Sincerely,

Ralph F. Lundregan Government Relations Manager

TITLE: FMVSR INTERPRETATION

TEXT: This responds to your recent letter requesting an interpretation concerning folding jump seats you intend to install in some future van models that your company manufacturers. You ask whether the seats would qualify as "designated seating positions", for purposes of the Federal motor vehicle safety standards.

The term "designated seating position" is defined in 49 CFR Part 571.3 as:

any plan view location capable of accommodating a person at least as large as a 5th percentile adult female, if the overall seat configuration and design is such that the position is likely to be used as a seating position while the vehicle is in motion, except for auxiliary seating accommodations such as temporary or folding jump seats . . . . (emphasis added).

As described and illustrated in your letter, the Nissan seats in question appear to qualify as folding jump seats. Consequently, under the definition above they would not be considered "designated seating positions". Although this is the case, we encourage you to install safety belts for these jump seats as you had previously planned. Likewise, we hope you will ensure that the seats have a crashworthiness performance equivalent to that required by Safety Standard No. 207 (for "designated seating positions") when the jump seats are folded into place for occupant use.

Mr. Thomas E. Cole Tire Division Rubber Manufacturers Association 1901 Pennsylvania Avenue, N.W. Washington, D.C. 20006

Dear Mr. Cole:

This is in response to your letter of April 14, 1980, regarding two apparent discrepancies in the revised Uniform Tire Quality Grading tread label format, published on November 29, 1979, in Docket 25, Notice 35 (44 FR 58475). As you note, the word "Vehicle" was omitted from the term "Federal Motor Vehicle Safety Standard No. 109" under the heading "Temperature" in Figure 2, Part II, of the regulation as published. This was an inadvertent omission which the National Highway Traffic Safety Administration (NHTSA) plans to correct in a future notice.

You also point out that paragraph (d)(1)(i)(B)(1) of the regulation (49 CFR 575.104(d)(1)(i)(B)(1)), applicable to tires manufactured prior to October 1, 1980, provides for use of the heading "DOT QUALITY GRADES" in capital letters, while Part I of Figure 2 of the regulation contains the heading "DOT Quality Grades" using lower case letters. The label format specified in paragraph (d)(1)(i)(B)(1) parallels the label format originally announced in Docket 25, Notice 24 (43 FR 30542; July 17, 1978), the heading of which used all capital letters. Since Part I of Figure 2 is not required on labels printed in accordance with paragraph (d)(1)(i)(B)(1), the use of lower case letters in the heading of Part I does not affect the requirements of paragraph (d)(1)(i)(B)(1). NHTSA will permit, at the manufacturer's option, the use of all capital letters in the heading of Figure 2, Part I, in printing labels to comply with the new two-part label format.

Sincerely,

Frank Berndt Chief Counsel

National Highway Traffic Safety Administration 400 Seventh Street, S.W. Washington, D.C. 20590

SUBJECT: 49 CFR Part 575.104

Gentlemen:

Docket 25; Notice 35 was published in the November 29, 1979 Federal Register. The amended labeling requirements permit the use of labels employing the original format, at the manufacturers' option, until October 1, 1980. As the tire manufacturers have prepared their new labels using the format specified in Notice 35, two minor discrepancies have been noticed.

In the explanatory information under Figure 2 for Temperature, the word "vehicle" has been left out of the term "Federal Motor Vehicle standard No. 109." We assume the omission of the word "vehicle" is not intended and will undoubtedly be included in the labels prepared by tire manufacturers.

The second discrepancy noted is concerned with capital versus lower case letters of the term "DOT QUALITY GRADES." In Paragraph (B)(1) it says that the label shall contain information "in the form illustrated in Figure 2, Part II, bearing the heading DOT QUALITY GRADES." Figure 2 shows part of the phrase "DOT QUALITY GRADES" being in lower case letters. Thus, in one place in the regulation, it is required that all letters in this phrase be in capital letters, and in another place it is required that part of letters be in lower case.

Sincerely yours,

Thomas E. Cole Vice President Tire Division

Dear Mr. Hitt:

This is in reply to your letters of April 11, and April 25, 1980, respectively to this agency and to Mr. Vinson of this office, These letters reference requirements for side marker reflectors and clearance lamps for trailers used to carry agricultural products over the public roads.

You say that your trailers travel "as much as several hundred miles on the highways at all hours of the day and night". Therefore, they are "motor vehicles" subject to all applicable Federal Motor Vehicle Safety Standards.

I enclose a copy of Federal Motor Vehicle Safety Standard No. 108 (Title 49, Code of Federal Regulations, section 571.108). You will see that marker lamps and reflectors are required on all trailers, while rear clearance lamps need be added only if the overall width of a trailer is 80 inches or more. A clearance lamp facing to the rear may be combined with a rear side marker lamp; we assume that is what you mean by a "side clearance lamp" as the standard speaks only in terms of "front" and "rear" clearance lamps.

You have also asked for the "early history" of why these lamps are required pursuant to "Regulation #393.15". As a matter of clarification that section of Title 49 is enforced by a different agency, the Bureau of Motor Carrier Safety, Federal Highway Administration, and covers lighting equipment required for commercial vehicles being used in interstate commerce. Our lighting standard, essentially identical, must be met before the vehicle is used, i.e., from time of manufacture until time of sale. To answer your question, clearance lamps must indicate the overall width of the trailer, in order that other drivers may be alerted to the presence on the road of a large vehicle. Side markers help identify the presence of a vehicle whose head lamps or taillamps may not be seen by a driver approaching it from a 90 degree angle, such as at an intersection.

In reference to my telephone conversation with Mr. Brooks of your office, I am sending the additional information you requested. We are interested in side markers and side clearance lamps for farm hauling equipment such as peanut haulers, cotton haulers and other typed of trailers which are not self propelled. These trailers would be used to carry the product from the farm to market or other distribution point. Sometime traveling as much as several hundred miles on the highways at all hours of the day and night. We would like to know what the legal requirements are for this type of equipment. Also the early history of why side markers and side clearance lamps are used on small semi-trailers and full trailers as required by the Department of Transportation, Regulation #393.15.

If you can not supply this information, could you direct us to where we can find it.

Thank you for your cooperation.
