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.

Dear Mr. Peterson:

This is in reply to your letter of February 7, l99l, to the Office of Chief Counsel asking for a clarification of allowable mounting locations and photometric output requirements for tail/stop lamps on passenger cars.

One of your clients wishes to mount "two-part" stop/tail lamps "so that one lamp is mounted on the fixed quarter panel and a duplicate lamp is mounted on the trunk lid." Each part of the two-part lamp is a combination tail/stop lamp. You have asked whether the minimum photometric requirements must be met by "the lamp mounted to the quarter panel or may the portion mounted on the trunk lid count toward the photometric requirements."

Your "two-part lamp" would be treated as two separate lamps. For purposes of compliance, only one of these two adjacent lamps must be designed to conform to Standard No. l08, and this conformance must be independent of any "contribution" by the adjacent lamp. Although Standard No. l08 permits either the deck or the body mounted lamp to be the complying lamp, it would be our preference that the body mounted lamp be the one that complies, so that the benefit of a conforming stop/tail lamp would be realized during those occasions when the lid may be raised.

Sincerely,

Paul Jackson Rice Chief Counsel

TITLE: FMVSR INTERPRETATION

TEXT: This is in response to your January 29, 1976, letter to Secretary Coleman, concerning problems with your 22 foot Executive "MINI" Motorhome.

@@ 567.4(g)(3) and 567.5(a)(5) of 49 CFR Part 567, Certification, provide that a motor vehicle's Gross Vehicle Weight Rating (GVWR) shall

not be less than the sum of the unloaded vehicle weight, rated cargo load, and 150 pounds times the vehicle's designated seating capacity.

Your letter and its enclosures indicate that your vehicle's weight is 9180 pounds, its designated seating capacity is six, and the GVWR specified by Executive is 9000 pounds. From this information, there appears to be a violation by Executive of Part 567. In addition, the possibility that the rear axle may be overloaded under normal conditions of use may constitute a defect related to motor vehicle safety. I have forwarded your letter to our Office of Standards Enforcement for such further action as may be appropriate.

Please note that a final-stage manufacturer is not automatically prohibited from certifying a GVWR that differs from that specified by the chassis manufacturer. For the purposes of the Federal motor vehicle safety standards and regulations, Executive is free to certify a lower GVWR, provided the above-cited constraint is observed.

The remaining questions presented in your letter are not matters over which we have jurisdiction, and probably are most appropriately handled by a private attorney.

TITLE: FMVSR INTERPRETATION

TEXT: This is in reply to your letter of August 1, 1972, to the attention of Mr. Jerome Palist of our White Plains, New York Office, concerning certification requirements for a vehicle which you describe and indicate will be used by a college to transport ball teams and school personnel, but will not be equipped with flashing lights or other special school bus equipment. You apparently wish to know whether you must consider this vehicle as a school bus for purposes of certification to Federal requirements.

"School bus" is defined in the motor vehicle safety standards to mean a bus "designed primarily to carry children to and from school, but not including buses operated by common carriers in urban transportation of school children" (49 CFR 571.3). Based upon the description you provide, the NHTSA would not consider the vehicle you describe to be a school bus. For purposes of certification to Federal requirements (49 CFR Parts 567 and 568), therefore, "gross vehicle weight rating" should not be computed under the minimum values specified for school buses. In addition, the requirement that vehicle type be inserted on the certification label should be met by inserting, "BUS."

This letter should not be construed to mean that the NHTSA takes a position as to whether this vehicle need, under State law, conform to requirements for school buses. The State must determine the scope and application of its own laws.

ID: 571.213--detachable base--crs3

Open

Dear [                    ]:

This responds to a January 7, 2020, letter from [               ] that [      ] emailed to us on [   ]. We apologize that we were unaware of the January 7 letter prior to your contacting us. The letter asks about Federal Motor Vehicle Safety Standard No. 213 (FMVSS 213), “Child restraint systems,” as applied to a child restraint system (CRS) consisting of a “shell” 1 and a separate, detachable base. [  ] asks us to confirm that the shell and base “need only meet the requirements of FMVSS 213 when evaluated together as a system.” As explained below, we disagree with this view.

[      ] asks about a CRS design concept it calls the “Z Project.” The Z Project child restraint system has the following three components: (1) a rear-facing-only infant car seat shell (the “Z Infant Shell”); (2) a convertible2 shell that is used both rear-facing and forward-facing (the “Z Convertible Shell”); and (3) a detachable base with permanently attached components for securing it to the vehicle with either the lower anchors of the LATCH3 system or a vehicle’s Type 1 or 2 belt system (the “Z Base”).4

[      ] would like to offer the Z Project for sale in the United States in the following variations, which it calls “Sales Variations”: (1) a Z Infant Shell and Z Base, packaged together at retail and sold as a system; (2) a Z Base sold separately at retail; (3) a Z Convertible Shell and Z Base, packaged together at retail and sold as a system; and (4) the Z Convertible Shell purchased separately upon verification that the consumer is in possession of a Z Base.

[     ] asks about the permissibility of Sales Variations 3 and 4 where the “Shell” of the convertible child restraint is a separate component from the base. According to [    ], the Shell and Base are separate parts and may not even be sold together. As explained below, we believe Sales Variations 3 and 4 are not permitted by Standard 213.

Sales Variations 3 and 4
Standard 213 (section S4) defines a “child restraint system” as “any device, except Type I or Type II seat belts, designed for use in a motor vehicle or aircraft to restrain, seat, or position children who weigh 36 kilograms (kg) (80 lb) or less.” Standard 213 requires “child restraint systems” to meet performance requirements to minimize the risk of injury in a crash and ease-of- use requirements to increase the likelihood of consumers correctly using and installing CRSs.

Any device meeting the standard’s definition of a “child restraint system” must be certified to Standard 213’s requirements.

Because the Z Convertible Shell (without the Z Base) consists of a molded frame structure that also has the padding, padding cover, harness belt straps, belt buckles and labeling of a conventional convertible CRS, the Z Convertible Shell (without the Z Base) is a device designed to “restrain, seat or position children who weigh 36 kg (80 lb) or less” in motor vehicles. Based on this information, we believe the Z Convertible Shell meets the definition of a “child restraint system” and is a child restraint system in and of itself, without the Z Base. As a CRS, the Z Convertible Shell must meet the applicable requirements of Standard 213 standing alone, without use of a separate part or accessory like the Z Base.

Apparent Non-Compliances
It does not appear that the Z Convertible Shell would meet all applicable requirements of Standard 213. We discuss two apparent non-compliances below.

a.    S5.3.2 of Standard 213 requires each convertible CRS to meet the requirements of the standard when installed solely by each of the following means: (1) a Type 1 seat belt assembly (lap belt);5 (2) a Type 1 seat belt assembly plus a tether anchorage, if needed; and (3) the child restraint anchorage system specified by FMVSS No. 225 (LATCH system).

As [       ] describes the Z Convertible Shell (p. 3 of your letter), “there is no belt path for vehicle belt installation and there are no lower anchor LATCH attachment mechanisms.” As such, it appears the Z Convertible Shell would not meet S5.3.2 as it has no means of attaching to a vehicle by a seat belt or by the child restraint anchorage system. The Z Convertible Shell depends on the Z Base for vehicle attachment, but the Z Base is wholly separate from the Z Convertible Shell. A CRS that cannot be installed solely by a belt and by a child restraint anchorage system will not meet S5.3.2.6

[    ] believes that Standard 213’s requirements apply to the “entire system” and not to the Z Convertible Shell alone. This view does not accord with the language of the standard. The Z Convertible Shell alone restrains, seats or positions children weighing 36 kg (80 lb) or less in motor vehicles and thus is a “child restraint system” in and of itself. It must meet S5.3.2 solely by the belt and LATCH system without having to depend on an added separate part.

[     ] view is also at odds with the purposes of S5.3.2, which is to standardize the means of vehicle attachment and increase the likelihood of a correct and safe installation. The standard requires CRSs to provide at least a minimum level of safety without use of additional parts, to ensure that the restraint will provide an adequate level of protection in the event the additional parts are not used.7 A CRS design whose minimal crash protection is dependent on a consumer’s using supplemental parts is contrary to this purpose and is not permitted unless explicitly provided for by the standard.

b.    S5.9(a) of Standard 213 requires each child restraint system to have permanently attached components that enable the CRS to be securely fastened to the lower anchorages of a child restraint anchorage system.8 The Z Convertible Shell attaches to the Z Base and the Z base is equipped with said components, but the Z Base is not a permanent part of the Z Convertible Shell. S5.9(a) states: “The components must be attached by use of a tool, such as a screwdriver.” The Z Convertible Shell does not have the child restraint anchorage system components attached to it by use of a tool like a screwdriver and so does not meet the requirements of S5.9(a).

One of NHTSA’s goals in establishing a child restraint anchorage system is to increase correct CRS use by ensuring that child restraint systems are convenient to install and use and are accepted by consumers.9 NHTSA adopted the “permanently attached” requirement in S5.9(a) to better ensure that the components on a CRS that attach to the child restraint anchorage system will be present and available for use by consumers through the life of the CRS.10 This is especially important with regard to child restraints, as it is common for child restraint systems to be handed down to others or otherwise re-used.

This interpretation is consistent with an April 26, 2007, interpretation addressing whether a CRS could be designed so that it attached to the child restraint anchorage system using a part that was called an “ISOFIX platform.”11 The ISOFIX platform appears similar to the Z Base: it alone had the child restraint anchorage system attachment and the CRS would attach to the ISOFIX platform. NHTSA stated the CRS design would not meet the requirements of Standard 213 because, although the CRS was designed to attach to the ISOFIX platform, FMVSS 213 requires the components attaching to the child restraint anchorage system to be permanently attached to the CRS. The agency did not regard the CRS and the ISOFIX platform as together comprising the “child restraint system.” Accordingly, NHTSA determined that the sale or importation of the CRS into the U.S. would be prohibited.

[    ] believes that the aforementioned Mercedes-Benz (MB) letter (footnote 7, supra) supports its view that NHTSA should apply FMVSS No. 213 to the Z Convertible Shell and the Z Base “together as a system.” The letter related to MB’s built-in12 booster seat that had a separate, non- integral “impact shield” and whether NHTSA would test the booster seat together with the impact shield. NHTSA said no, the booster seat must meet Standard 213’s requirements without use of the shield, because the impact shield was not part of the built-in CRS. We believe this outcome is consistent with our view in this letter that the Z Convertible Shell is a CRS unto itself and must meet Standard 213 without use of a separate part like the Z Base.

In answering MB, NHTSA also analyzed the applicability of the standard to various components of the MB system. [    ] focuses on the part of the MB letter that discusses whether the impact shield would be subject to the standard as an “add-on” child restraint system but, in doing so, [ ] appears to have misunderstood the context of and reasons for the agency’s statements. NHTSA’s statements related to its determination that the impact shield was not an add-on CRS due to the shield design and MB’s intention to sell the shield as part of the vehicle’s built-in system. NHTSA’s statement that the MB shield is “merely a component of a child restraint system and is not intended to be used separately from the other parts of the restraint system” was among those explaining why we concluded that the shield was not an add-on CRS that had to meet FMVSS 213 in its own right. The statements you quoted pertained to our decision that the MB shield was not an add-on CRS, and do not relate to how NHTSA would test an add-on system that had a separate part.

There are circumstances in which Standard 213 permits a child restraint to meet a requirement by way of a detachable base, but those situations are explicitly recognized in the standard and do not apply to your situation. For example, Standard 213 recognizes that some installation information may be on a detachable base (see, S5.5.3, which refers to the installation diagrams that must be visible when the CRS is installed).13 Another provision, discussed in a section below and one you ask about, relates to the last sentence of S5.9(a).

Your Question about the Last Sentence of S5.9(a)
The last sentence of S5.9(a) states: “In the case of rear-facing child restraints with detachable bases, only the base is required to have the components [that are permanently attached to the CRS that enable the restraint to be securely fastened to the lower anchorages of the child restraint anchorage system].” You believe this provision would permit the Z Convertible Shell to have the anchorage system components attached only to the detachable base (the Z Base).

Your understanding is incorrect. The provision only applies to rear-facing child restraints and does not apply to a convertible child restraint system like the Z Convertible Shell, because a convertible CRS is also a forward-facing child restraint system. If a child restraint could also be used forward-facing, the provision does not apply. NHTSA drafted the last sentence of S5.9(a) envisioning the provision as applying to “infant-only restraints with detachable bases.”14 The provision was adopted out of a concern at the time about the cost impacts of the rule on infant carriers (i.e., CRSs that are used rear-facing only).

Sales Variation 1
Please note that it appears the Z Infant Shell described in Sales Variation 1 must have a belt path for a vehicle belt installation (S5.3.2). The Z Infant Shell is a “child restraint system” under FMVSS No. 213 and, unless excepted by the standard,15 must meet the requirements of the standard standing alone without use of a separate part like the Z base. We cannot tell from materials whether there is a belt path on the Z Infant Shell itself. Please ensure that the Z Infant Shell in Sales Variation 1 has the required means of attaching by way of a vehicle seat belt assembly without the detachable base (Z base), as required by FMVSS No. 213 S5.3.2.

If you have other questions, please contact Deirdre Fujita of my staff at (202) 366-2992.

Ref: FMVSS No. 213

1 Based on your letter and submissions, the shell consists of a molded plastic frame structure and the padding, padding cover, harness belt straps, belt buckles and labeling of a conventional child restraint.

2 As defined on NHTSA’s website, a “convertible” CRS is a type of CRS that “converts from rear-facing for babies and smaller children to forward-facing for older and larger children.” https://www.nhtsa.gov/car-seats-and-booster- seats/car-seat-glossary. [Footnote added.]

3 “LATCH” refers to the child restraint anchorage system that FMVSS 225, “Child restraint anchorage systems,” requires to be installed in motor vehicles. Industry and advocates have developed the term “LATCH” to refer to Standard 225’s child restraint anchorage system.

4 According to [   ] letter: “The Z Infant Shell installed with the Z Base will accommodate children from 4 to 35 lbs. The Z Convertible Shell installed with the Z Base will accommodate children from 4 to 50 lbs. rear-facing and 22 to 65 lbs. forward-facing.”

5 NHTSA has proposed to amend Standard 213 to refer instead to a Type II belt (lap-shoulder belt). Notice of proposed rulemaking, 85 FR 69388, November 2, 2020. This proposal does not affect our determination here that the Z Convertible Shell must have a means to attach to the vehicle seat by way of the belt system.

6 The Z Convertible Shell would have to meet other performance requirements of FMVSS 213 without use of the Z Base. For instance, the Z Convertible Shell would have to meet the head and knee excursion requirements without the use of a tether strap.

7 Mercedes-Benz letter, https://isearch.nhtsa.gov/files/17513mer.b-i.htm. “Add-on, nonpermanent components can be lost or misplaced and may not be accessible when the restraint has to be used.” This interpretation concerns an “impact shield” that was not “formed as a unit” with the built-in CRS.

8 FMVSS 213 S5.9(a) inadvertently refers to a child restraint “anchorage” system instead of a “child restraint

system.” As indicated by the context of S5.9(a) and by the final rule adopting S5.9(a) (64 FR 10786, 10816; March 5, 1999), reference to “anchorage” is incorrect. NHTSA plans to correct the word soon.

9 LATCH final rule, 64 FR at 10797, col. 2.

10 In the rulemaking establishing FMVSS 225, NHTSA considered the merits of allowing vehicle manufacturers the option of installing an anchorage system that some CRSs could use only through an adapter that interfaced between the CRS and the anchorage system. Commenters overwhelmingly opposed an adapter, believing that the adapter would likely be lost or misused by consumers. The agency agreed and decided to adopt an anchorage system that would be universal to all vehicles and all CRSs. The Z Convertible Shell is contrary to NHTSA’s purpose in developing FMVSS 225 and the related requirements of FMVSS 213 S5.3.2 and S5.9(a), as the Z Base acts as an adapter that must be used for the CRS to attach to the anchorage system.

11 Gazza letter, https://isearch.nhtsa.gov/files/005431rls.htm.

12 FMVSS No. 213 (S4) defines a “built-in child restraint system” as “a child restraint system that is designed to be an integral part of and permanently installed in a motor vehicle.” An “add-on” system is a portable child restraint system (S4).

13 In a January 16, 2003, letter (Meyer letter, https://isearch.nhtsa.gov/files/00070cmc.html), the agency addressed whether a CRS with a detachable base must have information labeled on the base if the seating portion of the CRS was already properly labeled. The agency said no, “a detachable base is part of a child restraint system” so “[a]s

long as the labeling requirements are met by the system as a whole, the base is not required to be labeled.” We do not give weight to this letter as it was narrowly focused on labeling, did not analyze S4’s CRS definition, S5.3.2, and S5.9(a), and was overtaken by the April 26, 2007 Gazza letter, supra, that found an ISOFIX platform not to be part of the child restraint. To the extent the Meyer letter is inconsistent with this and the Gazza letter, we consider the Meyer letter superseded.

14 Final rule preamble, 64 FR at 10806 (col.3). The discussion of the provision begins with: “Several commenters addressed the requirements that would apply to infant-only restraints with detachable bases.”

15 E.g., as noted above, the last sentence of S5.9(a) permits the rear-facing child restraint to use the Z Base to attach to the child restraint anchorage system, and S5.5.3 provides for some labeling to be on a detachable base.

Dear Mr. Holland:

This responds to your letter of February 24, 1995, regarding the passive restraint phase-in requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 208, Occupant Crash Protection. You asked whether an importer which "imports Canadian specification MPV's (multipurpose passenger vehicles), such as the Chrysler Minivan, that meets (sic) the MPV passive restraint requirements of FMVSS 208 ... can count these vehicles toward the required percentage."

Section S4.2.5.6.1(a) states, "(a) vehicle that is imported shall be attributed to the importer." Thus, to determine compliance with the passive restraint phase-in requirements, Europa International should (1) count all trucks, buses, and mpv's with a gross vehicle weight rating of 8,500 pounds or less and an unloaded vehicle weight of 5,500 pounds or less, (2) count all such vehicles which meet the passive restraint requirements of FMVSS 208, and (3) determine if that class of vehicles is a sufficient percentage of the first class of vehicles to satisfy the phase-in requirements. However, as Mary Versailles of my staff cautioned you on the phone, some manufacturers are installing European (face) air bags but are not certifying that vehicles with such air bags meet the passive restraint requirements of FMVSS 208. Therefore, you should verify that any vehicle with an air bag is in fact certified to FMVSS 208's passive restraint requirements.

I hope this information has been helpful. If you have other questions or need some additional information, please contact Mary Versailles of my staff at this address or by phone at (202) 366-2992.

Dear Mr. Moore:

This responds to your letter of June 26, 1996, to the Administrator asking whether a provision of the California Vehicle Code is preempted by Federal Motor Vehicle Safety Standard No. 108.

Table II of Standard No. 108 requires that clearance lamps be located "on the front and rear." However, paragraph S5.3.1.1.1 allows them to "be mounted at a location other than on the front and rear if necessary to indicate the overall width of a vehicle, or for protection from damage during normal operation of the vehicle, and at such a location they need not be visible at 45

degrees inboard." California Vehicle Code Sec. 25100(e) requires that "Clearance lamps shall be visible from all distances between 500 feet and 50 feet to the front or rear of the vehicle."

We see no conflict between Standard No. 108 and CVC Sec. 25100(e). Standard No. 108 incorporates by reference SAE Standard J592e "Clearance, Side Marker, and Identification Lamps", July 1972. Table I specifies photometric minimum candela requirements that these lamps must meet at test points 45 degrees Left, Center, and 45 degrees Right. Thus, even if a clearance lamp is not visible at 45 degrees inboard, it is required to be visible directly to the rear and at 45 degrees outboard. We assume that at that location a clearance lamp would be "visible . . . to the rear of the vehicle" within the meaning of the California requirement.

If you have any questions, you may refer them to Taylor Vinson of this Office (202-366-5263).

"If the electric motor can only be activated by muscular power, (i.e., by pedaling the bicycle to a certain minimum speed), and the motor, once activated by muscular power, can continue to drive the bicycle even if the rider then stops pedaling (i.e., stops exerting muscular power), then the vehicle is still not deemed to be a 'motor vehicle.'"

This is an incorrect interpretation. If the motor, once activated by muscular power, can continue to drive the vehicle in the absence of muscular power, the vehicle is considered to be a "motor vehicle" since, without the input of muscular power, the vehicle is entirely "driven by mechanical power" with the meaning of the statutory definition of a "motor vehicle" (49 U.S.C. 30102(a)(6)). Our letter of May 22, says, in effect, that a vehicle is not a "motor vehicle" if, in the absence of muscular power, mechanical power alone is insufficient to drive it.

If you have further questions, you may call Taylor Vinson of this Office (202-366-5263).

Dear Mr. Cox:

This is in reply to your faxes of September 22, 1997, and October 1, 1997, to Taylor Vinson of this Office.

With your fax of September 22, you attached an article distributed by the Knight-Ridder newspapers on the arrival of the first Chinese truck or sport utility vehicle at a Michigan dealership. This article contains the statement that "since it's considered a low-volume vehicle, it needn't comply with U.S. safety standards. It doesn't have air bags and it doesn't meet U.S. crash standards." You have asked how they are allowed to do this.

The article is incorrect. All low-volume motor vehicles must comply with all applicable Federal motor vehicle safety standards in order to be imported and sold in the United States, unless it has filed for and received an exemption from the standards. As Mr. Vinson informed you in his call to you on October 1, no exemption has been granted this Chinese vehicle.

In your fax of October 1, you state that new Volkswagen Beetles are being imported under an exemption from NHTSA "allowing small volume importers to import 10 cars or less not to comply." You ask why you weren't told about this exemption. As with the Chinese Jeep, the Volkswagen Beetle does not have a small volume importer exemption. However, this vehicle could be imported as one that has been refurbished from an original vehicle that is more than 25 years old. If this is the case, then the vehicle is not required to comply upon admission to the United States.

We are providing copies of your correspondence to our compliance office. Thank you for informing us of these matters.

Sincerely,
John Womack
Acting Chief Counsel
