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.

TITLE: FMVSR INTERPRETATION

TEXT: This responds to your October 3, 1977, letter questioning the position of the National Highway Traffic Safety Administration (NHTSA) concerning the public dissemination of defect and noncompliance information by press release prior to a manufacturer's notification as required by Part 577, Defect and Noncompliance Notification. In your letter, you refer to a press release issued by the agency concerning defects in some of your vehicles. This release was made prior to your providing notification to the vehicle owners.

The NHTSA through Part 577 requires that manufacturers provide notification to the owners of vehicles involved in defect or noncompliance recalls. This notification must be provided, in the case of a manufacturer-initiated recall, within a "reasonable time" after a manufacturer discovers the existence of a defect or noncompliance. You conclude that the publication of an agency press release prior to the time that a manufacturer notifies owners of a defect or noncompliance in effect shortens the "reasonable time" allowed for such notification. This in turn, you suggest, results in unnecessary public concern before the manufacturer is capable of implementing the recall.

The publication of an agency press release does not shorten the time period allotted a manufacturer under Part 577 for providing notification. A manufacturer is still permitted a "reasonable time" to comply with the requirements. The NHTSA has adopted the "reasonable time" approach to manufacturer notification of owners, because it realizes that the amount of preparation to conduct a recall may vary depending upon the complexity of the defect or noncompliance.

The agency operates under different timing considerations than those applicable to a manufacturer. The NHTSA is under a mandate to ensure that vehicles containing potentially dangerous defects or noncompliances are corrected or removed from highway service as soon as possible. The agency understands that any recall and remedy process is somewhat time-consuming for a manufacturer, and accordingly, vehicles will not be repaired immediately. Therefore, in the interim time between a manufacturer's discovery of a defect or noncompliance and his notice and remedy, the agency must issue warnings to vehicle owners so that they can take the appropriate action. Such action might include checking their vehicle for possible signs of failure or discontinuance of use of the affected vehicle.

In summation, the agency must balance the manufacturer's need for a reasonable time to notify and remedy with the vehicle owner's need for immediate information pertaining to any potential safety problems. This balance has taken the form of the NHTSA's issuance of a warning pending a manufacturer's issuance of notification. The NHTSA concludes that through this mechanism safety is preserved and manufacturers are not unduly burdened.

RE: Press Releases/Safety Recalls

As I am sure you have been informed, we met with Mr. Dugoff and other representatives of your staff on September 21 for the main purpose of discussing the recent press release issued by your office concerning IH safety recall #77 V-127 and specifically, whether releases of that nature represent a new policy of your Department. As a related issue, we also discussed the procedure used by your Department regarding defect investigations. As we advised Mr. Dugoff, we are writing this letter to confirm our understanding of certain aspects and to provide you with a short written memorandum expressing our position with respect to such press releases.

With respect to the corolary issue of defect investigation and determination, we were advised by Mr. Berndt that NHTSA did have a policy of following the procedure detailed in your proposed rulemaking on the subject and that the manufacturer would be advised if NHTSA intended to issue such a determination of defect. In other words, a manufacturer need not expect a public announcement of the defect determination to be made prior to advice to the manufacturer that such determination was being made.

With respect to the main subject of our meeting, the press release on recall #77 V-127, our Company is extremely concerned with the practical results of that release, both in its content and in its timing. The following is a sample of the problems which result therefrom:

1. No Company personnel or IH dealers were knowledgeable of the recall or its repair techniques;

2. Needless public anxiety was created -- hundreds of calls were made since the DOT did not identify the models involved;

3. U.S. Army-Germany pulled all IH vehicles off the road;

4. Two large U.S. based fleets notified IH that they would either park or deadline all IH vehicles, possibly exposing IH to damage claims for downtime due to the commercial nature of the vehicles;

5. Three other large fleets indicated that they were considering putting IH vehicles out-of-service, with the same result as 4 above;

6. IH press release issued after DOT's identifying the specific trucks involved and adding repair information is totally ignored by the U.S. Press.

All internal IH Company actions such as customer notification letters, engineering approved repair techniques, repair instructions, repair parts ordering and packaging, vehicle quantities involved and identification, and registered owner identification, as illustrated in the attached chart, necessarily start after the defect determination. It follows, therefore, that in most cases, IH could not inform its dealers and field sales and service personnel in time to handle inquiries and/or repairs if DOT persists in the practice of utilizing the initial 5 day defect report as the source information for NHTSA press releases which are made prior to our "preparing" our recall.

With respect to our position that the press release was premature, your office repeatedly queried as to whether or not it was the position of IH that safety defects should remain concealed from the public. Obviously, that is not our position, but it is our position that we should comply with the current regulations governing the subject. Specifically, Part 577, Defect the Noncompliance Notification, has recently been amended to add certain parameters to this Part which were not present in the existing Rule. Specifically, one of the purposes of the amendment was to specify "the content, timing, and form of the notification that complies with the requirements set forth in Section 153 of the Act." (Emphasis added) Section 577.7(a)(1) was specifically included and provided that the customer notification must "Be furnished within a reasonable time after the manufacturer first determines the existence of a defect which relates to motor vehicle safety. . ." (Emphasis added) It is our understanding that this timing was included since a manufacturer necessarily needs some amount of time in order to prepare for a recall. Prior to creating customer reaction when the problem is yet insolvable, we strongly believe that the referenced sub-section was intended squarely for the purpose of allowing a manufacturer the time to prepare to remedy defects prior to customer notification. It would appear to us that the "reasonable time" which the law now allows us is being shortened by means of the early press release policy.

The press release was issued based on information contained in our statutorily required 5 day defect notice. It is our understanding that the purpose of the 5 day notice, as detailed in Part 573.2, is to enable your office to analyze the adequacy of our defect notification and corrective action, owner response thereto and to compare defect incidents rates among different groups of motor vehicles. Therefore, our compliance with this Part, and for the purposes above stated, in fact result in a different purpose being accomplished, namely, public notice of the defect earlier than the time of such notice required by Part 577. It certainly appears to us to be an anomaly that information provided for one purpose in fact ended up being used for another, seemingly in derogation of our rights under Part 577.

In summary, the view we wish to express is not that we oppose all press releases, but rather that we think a properly timed press release could be far more effective if it was coordinated with the time of the manufacturer's customer recall letters, assuming, of course, that such letters are sent within the reasonable time allowed. We are in no way suggesting that a press release should be held off in all cases, even those where a manufacturer is unreasonably delaying customer notification. We do believe that coordinated timing would enhance the initiation of a campaign. We respectfully request that you give this matter your attention and consideration.

TEXT: This responds to your September 2, 1977, letter concerning the applicability of Standard No. 217, Bus Window Retention and Release, to a thermopane driver's window in a bus.

In response to your first question, the window to which you refer is required to comply with the requirements of the standard. The fact that it is a driver's window does not exempt it from the coverage of the standard.

Your second question asks how to test thermopane glazing. According to our enforcement staff, testing of thermopane windows can be conducted using the same criteria used for other window glazing. By following the procedures established in S5.1 of the standard, you should be able to accurately test thermopane glazing.

Frank A. Berndt Acting Chief Counsel U.S. Department of Transportation National Highway Traffic Safety Administration

A question has arisen as to the qualification of an interpretation in a test to be performed on a driver window in a bus we are to supply to our customer.

Subject window is a dual slider containing thermopane glazing and we would appreciate clarification with regard to FMVSS 217. Is it necessary for a test performance in compliance to FMVSS 217?

If test is necessary, how should interpretation of force be measured with regard to thermopane which consists of two 3/16" thick pieces of glass with a 1/4" thick space sealed unit?

Your clarification in this matter would be appreciated. Thank you for assisting us in this matter.

TEXT: This responds to your letter of October 27, 1977, asking whether the use of two rearview mirrors in one mounting is permitted if one of the mirrors fails to meet Federal requirements.

Safety Standard No. 111, Rearview Mirrors (49 CFR 571.111), requires each passenger car to have an outside rearview mirror of unit magnification (plane mirror) on the driver's side of the vehicle. Paragraph S4.2.1 of the standard specifies the field of view that must be provided by this outside mirror. Provided the vehicle is equipped with one mirror that meets the requirements of paragraph S4.2.1, the use of additional, non-complying, mirrors is not precluded by the standard, even if the mirrors are in the same mounting with the complying mirror.

Please contact us if you have any further questions.

FROM: Robert D. Scifres

SUBJECT: Request for interpretation - Motor Vehicle Safety Standard No. 111, S3.2.1.1

As can be seen in the attached drawing(Exhibit I), this outside rearview mirror for passenger cars incorporates the use of two mirrors located in one assembly. One mirror(A) would conform in all respects to the current standards. The second mirror(B) would conform to all standards except as it relates to the field of vision. In itself the height would not provide the required reflected field of vision, but in conjunction with mirror (A) would provide an expanded field of vision to the extent the "blind spot" would be eliminated. Each mirror is adjustable both horizontally and vertically, allowing the driver to adjust each to give him the maximum reflection.

While the standards do not specifically nor indirectly state a single faced mirror only will be allowed; and although paragraph (1) of 32 F.R. 2413, dated February 3, 1967 relates to a "supplemental" mirror in addition to the inside and outside mirrors; and subsequent revisions do not change the above, I strongly feel an interpretation is in order.

My request comes about because of a very near accident involving me when I started to change lanes on a high speed highway. After checking both inside and outside rearview mirrors, I started to pull into the next lane to my left. Only because the driver of the vehicle behind me was alert prevented a serious accident. I have discussed this situation with about one hundred fifty of my acquaintences and almost all have experienced the same thing in one degree or another with several actually having an accident and three involved in rear end collisions because they had turned their head to make sure about the blind spot only to ram the rear of the cars in front of them.

In view of the standards as written, I feel an interpretation should be given and I shall appreciate an early response to this request

TEXT: This responds to your August 18, 1977, letter asking whether the head protection zone requirements of Standard No. 222, School Bus Passenger Seating and Crash Protection, apply to a portion of your bus located directly above the side windows.

You enclosed a sketch which details the bus sidewall and roof structure. On that sketch, you have shaded a small area asking whether that portion of the bus constitutes part of the bus sidewall or part of the roof structure. The head protection zone requirements of the standard (S5.3.1.1) do not apply to the sidewalls of school buses.

The National Highway Traffic Safety Administration (NHTSA) interprets your sketch to show the sidewall ending and the roof structure beginning at the point where the radius of curvature of the interior structure decreases sharply (see the point marked "A" on the sketch). Since the shaded portion of your sketch falls below that point, it is considered part of the sidewall and need not comply with the head protection zone requirements.

Joseph Levin, Chief Office of Chief Council N.H.T.S.A.

RE: FMVSS 222 Pora. S5.3.1.1.

A clarification of the above referenced standard is urgently needed. Due to the "tumble home" type of the side of some van-type school buses, there is no clear distinction where the side wall would end and the roof structure would start.

S5.3.1.1. of FMVSS 222 states that the head protection zones are the spaces in front of each school bus passenger seat which are not occupied by bus side wall, window or door structure . . . etc.

Please refer to the enclosed sketch and note that the outboard plane (S5.3.1.1. (c)) of the head protection zones intersects the wall at approximately the window header point. The wall extends upward and inward from that point. This leaves an area, indicated by the shaded portion of the sketch that would extend into the head protection zone. Is this configuration in compliance with the standard? There is no greater hazard to the occupant from the window header to well above the upper limits of the head protection (Illegible Word) than any where in the wall area.

It is very urgent that we get an opinion on this just as soon as possible. After you have reviewed this, we would like to phone or if necessary come to your office for the clarification.

Thanking you in advance for your consideration.

TEXT: This responds to your letter asking whether your modifications of Toyota pickup trucks comply with the requirements of the National Highway Traffic Safety Administration (NHTSA).

The NHTSA requires that a person who modifies a vehicle attach a label to the vehicle indicating that, as modified, the vehicle continues to comply with all safety standards (49 CFR Part 567. Certification). From your letter, it appears that you are in compliance with this requirement. You should note further that section 108(a)(2)(A) of the National Traffic and Motor Vehicle Safety Act of 1966 (15 U.S.C. 1381 et seq.) prohibits a manufacturer, distributor, dealer, or motor vehicle repair business from rendering inoperative any device or element of design installed in a motor vehicle or an item of motor vehicle equipment in compliance with a Federal safety standard. In the case of a vehicle which is being converted from one vehicle type to another (e.g., a sedan to a convertible), modification of safety systems would not violate section 108 as long as the modified systems complied with the standards that would have been applicable to the vehicle had it been originally manufactured as the vehicle type to which it is being converted.

As long as you ensure that the vehicle continues to comply with all of the standards applicable to it and you do not render inoperative any safety device or element of design, you would appear to be in compliance with the agency's requirements. You should note that the waiver signed by your customers would not remove your responsibility for any defects or noncompliances with our standards.

The intent of the alteration regulation is to make vehicle alterers responsible for the continued compliance of the vehicles they modify. Therefore, an alterer would be held responsible for any noncompliance of a vehicle caused by his alterations. The National Highway Traffic Safety Administration would not hold the alterer liable for noncompliances in a vehicle that were the responsibility of the original vehicle manufacturer and not affected by the alterer's conduct.

Enclosed is a photo showing the location of the wording "Emergency Door" on the rear of a school bus.

This is in reference to our phone conversations regarding Section S5.5.3. School Buses of 17 August, 1977. (F.M.V.S.S. - 217)

The glass area at the top will have an illuminated sign with the words "School Bus". When not used as a school bus by State Law it must be covered.

The result is that the cover does not permit the word "Emergency Door" to be on top of the door and, also, the size required by S5.5.3. Pennsylvania requires a three (3) (Illegible Word) letter which is impossible.

Actually, we feel that the location on a school bus as pictured is safer particularly in a vertical position since it is closer to a person eye level.

We trust you will look with favor upon this request, and wish to thank you for your courtesies to us during our phone conversations.

TEXT: This responds to your August 4, 1977, letter asking whether the remanufacture of a school bus using a new chassis and an old school bus body constitutes the manufacture of a new school bus subject to the new Federal school bus safety standards.

The National Highway Traffic Safety Administration has determined that the manufacture of a vehicle using a new chassis and an old body is the manufacture of a new vehicle. (Part 571.7, Title 49, Code of Federal Regulations.) In this regulation the agency indicated that the only time that the remanufacture of a vehicle would be exempted from compliance with the new safety standards is when an old chassis is combined with a new body. In those situations, the vehicle is considered a used vehicle not subject to the standards.

In the case to which you refer, the combination of a new chassis and an old school bus body would require that you modify the bus body to comply with all of the Federal school bus safety standards in effect on the date of your manufacture of the new bus.

This office represents the County School Board of Fairfax County, Virginia. A 1975 school bus was damaged extensively in November of 1976, and due to the failure of the insurance company for the responsible driver to pay, we have had to look very carefully into the question of damage to school buses.

In my search for an economical way to repair this bus, I have discovered that there are new regulations from the National Highway Traffic Safety Administration dealing with the installation of old school bus bodies on chassis manufactured after April 1, 1977. In this case, putting the old school bus body onto a chassis would be the cheapest way to repair the bus but it appears that this runs afoul of regulations of your agency.

I would appreciate very much your advice on this matter, especially your direction as to the regulations which control this matter.

TEXT: This responds to your August 25, 1977, letter asking several questions about the applicability of Standard No. 217, Bus Window Retention and Release, to buses other than school buses.

Your first state your conclusion that paragraph S5.2 of the standard applies only to buses other than school buses. Your interpretation of S5.2 is correct. Secondly, you state that S5.2.1 applies to all buses with GVWR's of more than 10,000 pounds. This assertion is incorrect. See S5.2.3. Paragraph S5.2.1 applies only to buses other than school buses that have GVWR's greater than 10,000 pounds.

Your final inquiry pertaining to Standard No. 217 concerns the requirement for unobstructed emergency exits in both school and non-school buses. You first correctly state that paragraphs S5.4 through S5.4.2.1 describe the required size of the unobstructed openings for school buses. You then claim that there is no equivalent description for the size of unobstructed openings required in buses other than school buses. This last statement is not entirely accurate. The amount of unobstructed emergency exit openings required for buses other than school buses is detailed in S5.2. This section establishes requirements for the total area of unobstructed emergency exit openings and for the location of those exits. This section also specifies the extent to which the area of each exit is to be counted in determining compliance with the total unobstructed opening requirement. Therefore, although the standard does not specify minimum size requirements for individual exits in buses other than school buses, the standard does contain other requirements for unobstructed openings in buses other than school buses.

You concluded in your letter that buses other than school buses are not required to use the parallelepiped device in determining whether their rear exits comply with the requirements. This conclusion is accurate. For purposes of clarity, however, you should note that Standard No. 217 does not mandate rear doors in buses other than school buses. Those buses can utilize either rear exits or roof exits. Further, regardless of the fact that you use a rear emergency door in buses other than school buses, you must insure that you also provide the other mandatory exits and the correct area of unobstructed openings as described in paragraphs S5.2 through S5.2.2.

Attn: Roger Chilton

The purpose of this letter is to request an interpretation of FMVSS No. 217 regarding the range of it's application, as follows: Para.S.5.2 - Speaks to buses other than schoolbuses and requires "unobstructed" openings for emergency exit . . ." going on to define the area requirements.

Para.S.5.2.1 - Speaks to "Buses with GVWR of more than 10,000 pounds". This presumably covers all buses. It further states that ". . . buses with a GVWR of more than 10,000 lbs. shall meet the unobstructed openings requirement by providing . . . one rear exit that conforms to S.5.3 through S.5.5".

Under paragraph S.5.4 thru S.5.4.2.1.(a) as amended May 25, 1976, the unobstructed opening of a school bus is described as "an opening large enough to permit unobstructed passage of a rectangular parallelepiped 45 inches high, 24 inches wide and 12 inches deep, keeping . . .". There is no description that pertains to the unobstructed opening of a non-school bus.

We have, therefore, decided that the non-school bus needs only a 12 inch wide clear aisle opening at the rear door to meet the requirements of FMVSS 217. Is this interpretation correct?

We would appreciate an early answer to this query.

TEXT: Your recent letter to President Carter concerning the installation of a bench seat in a cargo van was forwarded to the National Highway Traffic Safety Administration for reply. You were apparently told by your local Ford dealer that Federal law prohibits the installation of a seat in the cargo area of a van vehicle.

The Ford dealer's representation to you was incorrect. There is no Federal law that precludes installation of a seat such as your letter describes; although, depending on the time and manner of the installation, the seat might be subject to Federal safety standards.

If the vehicle manufacturer (Ford) or your dealer installs the seat prior to the time you take possession of the vehicle, either will have to certify that the vehicle, including the seat, is in compliance with all applicable safety standards, as provided in the National Traffic and Motor Vehicle Safety Act, as amended (15 U.S.C. 1381 et seq.). Specifically, the installation of the seat would require compliance with Safety Standard No. 207, Seating Systems, Safety Standard No. 208, Occupant Crash Protection, and Safety Standard No. 210, Seat Belt Anchorages. If done by your dealer, he would be required to attach a label or tag to the vehicle certifying that, as altered, the vehicle was in compliance with all safety standards, including the three just mentioned (49 CFR 567.7).

If you first take possession of the vehicle, you or your dealer may then install an additional seat without certifying compliance with Federal safety standards (15 U.S.C. 1397). Your dealer would, however, be subject to section 108 (a)(2)(A) of the Vehicle Safety Act, which provides that no manufacturer, distributor, dealer or motor vehicle repair business shall knowingly render inoperative, in whole or in part, any device or element of design installed on or in a motor vehicle in compliance with an applicable Federal motor vehicle safety standard. This means that the dealer would not be permitted to destroy the vehicle's conformity to any safety standard by his installation of the additional seat. We do strongly recommend that, for the safety of your child, you assure the seat and safety belts conform to the minimum performance requirements of our safety standards.

Perhaps it is the policy of Ford Motor Company and its dealers not to install additional seats in cargo vans because of the responsibilities mentioned above. The policy is not, however, a Federal law. I suggest you show this letter to your local dealer.

SINCERELY,

President Jimmy Carter

Dear Mr. President:

My husband will be starting a new independent business within the next several weeks that requires him to use a cargo van. We have ordered a 1978 Ford van and need a standard back seat directly behind the driver area. We were told it was a newly passed Federal law that prohibits the installation of a seat in the cargo area. Having exhausted our efforts locally and within our area, we are now in a position to seek assistance from the only person left to aid us in acquiring a seat for our van.

We are the parents of a severely retarded child twelve years of age who is unable to sit normally in a regular seat. We therefore are left to improvise by seat-belting him into a standard seat for transporting him from the various places in the reclinger position.

As I am employed in a part-time position in Delivery, ten miles from our home, it is necessary to use the van on those days for his father to bring him home while I work.

We are therefore requesting your assistance in acquiring a seat for our van by authorizing the Ford Motor Company to install a seat behind the driver equipped with seat belts for the convenience of a handicapped child Please consider this special privilege we are requesting and it is our hope that placing yourself in the same position you will be able to understand the plight.

Your simple attention to this request will be greatly appreciated as our order has not been processed as of this date and we need your authorization to complete our order.

Thanking you in advance.

Mary Edwards Foster

P.S Our order was placed with the Reavis Ford, Inc.

To Whom It May Concern:

Christopher Lee Foster, son of Mr. & Mrs. Edward L. Foster is severly physically and mentally retarded with I Q definitely under 40.
