NHTSA Interpretation File Search
Overview
NHTSA's Chief Counsel interprets the statutes that the agency administers and the standards and regulations that it issues. Members of the public may submit requests for interpretation, and the Chief Counsel will respond with a letter of interpretation. These interpretation letters look at the particular facts presented in the question and explain the agency’s opinion on how the law applies given those facts. These letters of interpretation are guidance documents. They do not have the force and effect of law and are not meant to bind the public in any way. They are intended only to provide information to the public regarding existing requirements under the law or agency policies.
Understanding NHTSA’s Online Interpretation Files
NHTSA makes its letters of interpretation available to the public on this webpage.
An interpretation letter represents the opinion of the Chief Counsel based on the facts of individual cases at the time the letter was written. While these letters may be helpful in determining how the agency might answer a question that another person has if that question is similar to a previously considered question, do not assume that a prior interpretation will necessarily apply to your situation.
- Your facts may be sufficiently different from those presented in prior interpretations, such that the agency's answer to you might be different from the answer in the prior interpretation letter;
- Your situation may be completely new to the agency and not addressed in an existing interpretation letter;
- The agency's safety standards or regulations may have changed since the prior interpretation letter was written so that the agency's prior interpretation no longer applies; or
- Some combination of the above, or other, factors.

ID: 0484Open Mary M. Mann, Director Dear Ms. Mann: This responds to your letter of September 15, 1994, to Patrick Boyd of this agency. As he has told you, we did not receive a copy of it until around November 9. You ask for confirmation of your understanding of the conspicuity requirements of S5.7.1.4 of Federal Motor Vehicle Safety Standard No. 108 as they apply to large boat trailers, based upon a meeting you had with him and Taylor Vinson of this Office earlier in the summer. We have paraphrased your concerns for conciseness in our discussion which follows. Side treatment 1. Paragraph S5.1.1.9 allows a double-faced clearance lamp to be mounted at or near the midpoint of wide boat trailers to indicate the extreme width. Paragraph S5.7.1.4, in essence, prohibits retroreflective material from being closer than 75 mm to the edge of any required lamp. While the closest edge of the fender-mounted lamp will be further than 75 mm from the body-mounted retroreflective material, when viewed from the side the separation distance vanishes and the material appears next to the lamp. You asked whether this configuration complies with Standard No. 108. NHTSA regards this configuration as meeting the requirements of Standard No. 108 since the actual physical distance between the closest edge of the lamp and the material is more than 75 mm. But the more important point is that the spacing of side conspicuity material is a consideration only for required side lamps. The amber lamp in question is a front clearance lamp and the proximity of side facing reflectors has no effect on its visibility from the side. 2. Paragraph S5.7.1.4.1(a) requires that the material cover at least half the trailer length and that it be distributed as even as practicable. For purposes of calculating the 50 percent minimum, you asked whether the following two applications are acceptable: a) The sheeting can be on the angled portion of the trailer that is the tongue, regardless of its effect on the reflectivity of the tape when viewed from the side. NHTSA has traditionally included the trailer tongue in determining the overall length of the vehicle for compliance purposes. Therefore, sheeting applied to the trailer tongue may be used in calculating the 50 percent minimum. (b) The sheeting need not all be on the same horizontal plane. This is correct. If a manufacturer applies sheeting to the tongue and fender in fulfilling the 50% minimum obligation, the material need not be at the same height as the other sheeting on the trailer. However, wherever applied, each discrete portion of sheeting must be mounted as horizontal as practicable. Rear Treatment 1. Paragraph S5.7.1.4.1 specifies the application of three Elements of sheeting to the rear of trailers. However, it excuses container chassis and platform trailers without bulkheads from being equipped with Element 2 treatment, and trailers without underride protection devices from the requirements of Element 3. You asked whether NHTSA would also excuse boat trailers without bulkheads in the same manner as platform trailers, requiring compliance only with Element 1. This is correct. The configuration of a boat trailer without a bulkhead is essentially that of a platform trailer, and it may also be exempted from providing Element 2 conspicuity treatment. Due to their low heights, boat trailers are not equipped with rear underride devices, and those trailers without underride devices are excluded from the requirement for providing Element 3 treatment. 2. Element 1 retroreflective material is to be applied "across the full width of the trailer" but under paragraph S5.7.1(a) it need not be applied to "items of equipment such as door hinges and lamp bodies." There is a cross member at the rear which will have conspicuity treatment across the full width; however, mounting brackets attached to the cross member obscure portions of the conspicuity treatment. You asked for confirmation that this configuration is in accordance with Standard No. 108. The exclusionary term "items of equipment" is not limited to the two examples cited in S5.7.1(a), door hinges and lamp bodies. We believe that any equipment to which it is impracticable to apply retroreflective material may be excluded from the requirement. You have not included any pictures of the mounting brackets, but this will confirm that NHTSA regards the mounting brackets as "items of equipment" to which the treatment need not be applied, if it is impracticable to apply material to it. In this event, application of conspicuity treatment across the full width of the cross member meets Standard No. 108 even if the subsequently added mounting brackets without treatment obscure part of it. 3. Does NHTSA interpret "full width of the trailer" to include the rear of the fender assembly, so as to require the application of conspicuity treatment to it? You asked for confirmation that the phrase applies only to the rear of the frame. NHTSA has defined "overall vehicle width" to exclude flexible fender extensions, but it has not adopted a definition for "full width." We understand from your first question, on the centrally mounted clearance lamp, that boat trailer fenders will be located at or near the center of the trailer rather than at the rear. Under this circumstance, we interpret "full width" to include only the vehicle structure at the rear end of the trailer, including its frame and rear cross members. 4. With respect to the relative location of the edge of retroreflective sheeting to the edge of required lamps, S5.7.1.4(b) prohibits white sheeting from being closer than 75 mm to the edge of any required lamp whether red or amber, while S5.7.1.4(c) prohibits red sheeting from being closer than 75 mm to the edge of any required amber lamp only. You asked for confirmation "that the edge of the red portion of the sheeting may abut a rear identification lamp but that the white portion of the sheeting must be at lease (sic) 3mm (sic) from those lamps." (We believe you mean 3 inches). This is correct. S5.7.1.4(c) does not prohibit red sheeting from being closer than 75 mm (3 inches) to the red rear identification lamp, and the two may abut. However, S5.7.1.4(b) does not allow the edge of white sheeting to be closer than 75 mm to the edge of the luminous lens area of the identification lamp. Finally, you have asked for confirmation of your understanding "that it is not acceptable for trailer manufacturers to give rolls of reflexive sheeting tape and instructions to dealers regarding its application. Rather, the sheeting must be installed at the factory." We confirm your understanding. The manufacturer of the trailer is required to certify compliance of its product with all applicable Federal motor vehicle safety standards upon its completion and before its delivery for introduction into interstate commerce. As this certification includes compliance with S5.7 of Standard No. 108, the conspicuity treatment must be applied as part of the manufacturing process and not delegated to dealers. Sincerely,
Philip R. Recht Chief Counsel ref:108 d:1/11/95

ID: nht76-4.38OpenDATE: 02/25/76 FROM: AUTHOR UNAVAILABLE; R. B. Dyson; NHTSA TO: State of Connecticut TITLE: FMVSS INTERPRETATION TEXT: This is in response to your letters of June 24, 1975, and May 30, 1975, regarding Federal Motor Vehicle Safety Standards Nos. 217 and 205. Please excuse our delay in answering your questions. In your letter of June 24, 1975, you asked whether Standard No. 217 applies to school buses, and if so, whether Connecticut's regulations concerning emergency exits for school buses are in conflict with the Federal standard. By notice published in the Federal Register on January 27, 1976 (41 FR 3871) Federal Motor Vehicle Safety Standard No. 217, Bus Window Retention and Release, 49 CFR 571.217, was amended to specify requirements for emergency doors for school buses, pursuant to the provisions of Section 202 of the Motor Vehicle and Safety Amendments of 1974 (Pub. L. 93-492, 88 Stat. 1484, 15 U.S.C. 1392). Since Standard No. 217, as amended, applies to school buses, effective October 26, 1976, any State regulations which differ are voided by @ 103(d) of the National Traffic and Motor Vehicle Safety Act of 1966 (15 U.S.C. 1392(d)). The Connecticut regulations are, therefore, preempted by Standard No. 217, since @ 103(d) requires the State regulations to be "identical" to the Federal standard. It should be noted, however, that while the State of Connecticut may not issue a regulation which differs from similarly applicable Federal Motor Vehicle Safety Standard requirements, Connecticut (or any of its political subdivisions) may in its own contracts for school bus purchases require more stringent specifications, as long as the Federal minimum requirements are met. In your letter of May 30, 1975, you asked whether Lucite AR and other similar rigid plastics are allowed for use as side windows of buses under Standard No. 205, even though S5.1.2.1 does not list the use for "Item 12" rigid plastics. "Item 12" is a classification created by the NHTSA for rigid plastics which comply with all the tests required of "Item 5" rigid plastics as defined in ANS Z26, with the exception of the test for resistance to undiluted denatured alcohol. Paragraph S5.1.2.1, Item 12 - Rigid plastics, provides that "Item 5" safety plastic materials may be used in motor vehicles only in the locations specified, at levels not requisite for driving visibility. These locations include "Standee windows in buses" and "readily removable windows". However, there is no provision in S5.1.2.1 which allows the use of "Item 12" plastic materials for fixed, side windows in buses. Standard No. 205 defines readily removable windows in buses having a GVWR of more than 10,000 pounds to include pushout windows and windows mounted in emergency exits that can be manually pushed out of their location in the vehicle without the use of tools, whether or not one side remains hinged to the vehicle. Rigid plastics can only be used for side windows in buses if the side window is a readily removable window as defined by S5.1.1.4 or a standee window. I hope this letter clarifies your questions concerning Standard Nos. 217 and 205. Please contact us if we can be of any further assistance. YOURS TRULY, STATE OF CONNECTICUT DEPARTMENT OF MOTOR VEHICLES June 24, 1975 Richard Dyson Assistant Chief Counsel U.S. Department of Transportation National Highway Traffic Safety Administration This is in regard to your recent reply to Mr. W. G. Milby, Staff Engineer from the Blue Bird Body Company in Fort Valley, Georgia concerning Connecticut regulations for emergency exits on school buses. I have no question with the response that State regulations must be identical to Federal standard or are considered void. I can understand the reasoning behind this decision and agree with it completely. The interpretation I would have is; Does Motor Vehicle Safety Standard #217 apply to school buses, and if it does; are Connecticut regulations concerning emergency doors and emergency windows in conflict with Motor Vehicle Safety Standard #217? I am attaching for your information copies of those sections of Connecticut regulations concerning emergency exits from the "MINIMUM REQUIREMENTS FOR TYPE I SCHOOL BUS CONSTRUCTION AND EQUIPMENT and all correspondence pertaining to this subject. Thank you for your cooperation and assistance in this regard. John L. O'Connell Pupil Transportation Administrator ATTACHMENTS BLUE BIRD BODY COMPANY May 19, 1975 Richard Dyson Assistant Chief Counsel U.S. Department of Transportation NHTSA The State of Connecticut recently adopted new school bus specifications which will become effective on school buses manufactured after January 1, 1976. In two areas these specifications are more restrictive than FMVSS 217 Bus Window Retention and Release. In section 14-275B-16 (d) and 14-275B-17 (a), (see attached copies), the Connecticut specifications call for emergency exit release forces of between 5 and 15 pounds and 5 and 20 pounds respectively. Since these forces are different than those required by FMVSS 217, this imposes an additional constraint on school bus manufacturers for that state. Also, we are concerned that latch forces as low as 5 pounds could result in inadvertent opening of emergency exits. We are in receipt of a copy of a letter which you sent to Mr. Donald L. Gibson, dated November 29, 1974, with file reference N40-30 (KK). In that letter you state: "The federal requirements must be regarded as conclusive with regard to parking brake performance and emergency braking capability in order to maintain the uniformity necessary in a federal regulatory scheme. If states were permitted to impose additional requirements in an area regulated by a federal safety standard, manufacturers would be confronted with an impossible task of compliance. This reasoning formed the basis of the recent decision rendered in a case brought by the Motorcycle Industry Council, Inc., against the State of California in the United States District Court for the Eastern District of California concerning the preemption of a California State requirement that motorcycle lamps be wired to operate when the engine is running. The court held that the California requirement is preempted by the Federal Motor Vehicle Standard 108 since the NHTSA intended to cover all aspects of performance directly involving motorcycle headlamps." It appears to us that this current conflict between the new Connecticut regulations and FMVSS 217 is similar to the matter which you addressed in your letter quoted above. In the light of such conflicting specifications, what is our responsibility as a school bus manufacturer. W. G. Milby Staff Manager cc: JOHN O'CONNELL; DAVE PHELPS MINIMUM REQUIREMENTS FOR TYPE I SCHOOL BUS CONSTRUCTION AND EQUIPMENT PAGES 9 AND 10 the release mechanism should be turned to open the emergency door shall be painted on the outside of the emergency door in black on the national school bus yellow background.

ID: 16054.ztvOpenMr. Bill Cox 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, |

ID: 12089.MLSOpen Mr. William Shapiro Dear Mr. Shapiro: This responds to your inquiry about the labeling requirements in S5.2.2.2 of Standard No. 116, Motor Vehicle Brake Fluid (49 CFR §571.116). You ask whether the wet boiling point marked on a package of DOT 4 brake fluid should be "the minimum wet boiling point of the DOT brake fluid in the container," or the minimum wet boiling point that DOT 4 brake fluid must meet under the standard, i.e., 311 degrees F. The answer is the former. Section S5.2 of Standard 116 sets forth packaging and labeling requirements for brake fluid containers. Section S5.2.2.2(f) requires each container to be marked with "The minimum wet boiling point in Fahrenheit of the DOT brake fluid in the container." (Emphasis added). Under S5.1.2, the wet equilibrium reflux boiling point ("wet boiling point") of DOT 4 brake fluid must not be less than 311 degrees F. Because section S5.2.2.2(f) specifically requires the labeling to be of the wet boiling point of the DOT brake fluid "in the container," the value for the brake fluid in the container is marked on the label. This interpretation is consistent with a February 7, 1975 letter to Mr. Paul Utans in which the agency concluded that a label that specified a wet boiling point of 320 degrees F. "meets our requirements." I hope this information is helpful. If you have further questions, please contact Mr. Marvin Shaw of this office at (202) 366-2992. Sincerely,

Mr. Robert M. Levy Manager, Design Engineering Abex Corporation Signal-Stat Division P.O. Box 438 Somerset, New Jersey 08873-3492
Dear Mr. Levy:
This is in reply to your letter of February 25, 1985, to Frank Berndt, the former Chief Counsel of this agency, asking for clarification of an interpretation of Safety Standard No. 108 that tnis agency furnished last year to Wesbar Corp.
On May 16, 1984, Wesbar asked whether the correct minimum effective luminous lens area on stop lamps and turn signal lamps was 8 square inches or 12 square inches, when intended for use on trailers whose overall width is 80 inches or greater. This office advised Wesbar on July 3, 1984, that, as specified in SAE J586c for stop.lamps and SAE J588e for turn signal lamps, the answer was 8 square inches. Your letter calls to our attention the fact that these SAE standards require each stop and turn signal lamp to have a minimum of 12 square inches in those vehicle configurations where two stop or turn signal lamps are mounted on the same side of the vehicle and are closer to each other than 22 inches.
Thank you for calling this oversight to our attention. Indeed, SAE J586c and J588e establish this exception to the general minimum requirement of 8 square inches. We are furnishing a copy of this letter to Wesbar and apologize for any confusion that the earlier letter has caused.
Sincerely,
Jeffrey R. Miller Chief Counsel

ID: nht68-3.43OpenDATE: 07/25/68 FROM: AUTHOR UNAVAILABLE; David A. Fay; NHTSA TO: Department of California Highway Patrol TITLE: FMVSS INTERPRETATION TEXT: Thank you for your letter of July 2, 1968, to Mr. George C. Nield, Acting Director, Motor Vehicle Safety Performance Service, concerning requirements for combination clearance and side marker lamps. Paragraph S3.3 of Motor Vehicle Safety Standard No. 108 permits the combination of two or more lamps providing the requirements for each are met. Table 1 in SAE Standard J592b gives the photometric requirements for both the clearance and side marker lamps, and Section J of the Standard permits their combination providing the combination complies with both clearance and side marker minimum candlepower requirements. Section J also defines the H-V axis of the combination as parallel with the longitudinal axis of the vehicle when checking clearance lamp test points, and normal to this vehicle axis when checking side marker test points. Your table of minimum candlepower requirements for the Type 2 combination lamp meets J592b and therefore Standard No. 108 providing you define the H-V axis as that of the side marker lamp. The requirements for the Type 1 combination as specified in your table will not meet J592b or Standard No. 108 unless you change H-10, -20, -30, -45, -60, -80 and -90, both 1, and R to H-15, -25, -35, -45, -55, -65, -75 and -90, both L and R, and define the H-V axis as a line through the center of the lamp at a 45 degree angle to the longitudinal axis of the vehicle. Your mounting instructions are considerably more restrictive than those implied in J592b and Standard No. 108. Actually, no additional mounting instructions are necessary, because any mounting which meets the minimum candlepower requirements of Table 1 in J592 and your table with the suggested revisions would meet the requirements of Standard No. 108. |

ID: 2253yOpen Ms. Linda B. Kent Dear Ms. Kent: Thank you for your letter requesting an interpretation of whether the use of a product on motor vehicles would violate Standard No. 205, Glazing Materials (49 CFR /571.205). This product, called "Contra Vision," is designed to display messages or advertising materials on windows and other clear surfaces, so that viewers on one side of the clear surface will see the message displayed, while viewers on the other side of the surface will see an essentially transparent surface without any message visible. According to your letter, this product "will be used for promotional signage in store windows, but also has application in rear taxicab windows, as well as rear and side windows of city buses." You asked for our opinion of whether this product complies with Standard No. 205. Some background on how Federal motor vehicle safety laws and regulation affect this product may be helpful. Our agency is authorized under the National Traffic and Motor Vehicle Safety Act to issue safety standards applicable to new motor vehicles and new items of motor vehicle equipment. NHTSA, however, does not approve or certify any vehicles or items of equipment, nor do we endorse any commercial products or processes. Instead, the Safety Act specifies that each manufacturer itself must certify that its products meet all applicable safety standards. The agency periodically tests vehicles and items of equipment for compliance with the standards, and also investigates alleged defects related to motor vehicle safety and alleged violations of other statutory provisions. Your letter indicates that you are already aware that NHTSA has issued a safety standard that applies to the windows installed in motor vehicles. Specifically, Standard No. 205 requires that all new vehicles and all new glazing materials for use in motor vehicles must comply with certain performance requirements. Among the requirements set forth in Standard No. 205 are specifications for minimum levels of light transmittance. A minimum of 70 percent light transmittance is required in glazing areas requisite for driving visibility, which includes all windows in passenger cars. In trucks and buses, the windshield and windows to the immediate right and left of the driver and the rearmost window, if the latter is used for driving visibility, are considered to be requisite for driving visibility, and therefore subject to the 70 percent minimum light transmittance requirement. Your letter did not provide any information on the light transmittance that would be measured through glazing with Contra Vision installed on it. The combination of the glazing material and the Contra Vision must allow at least 70 percent light transmittance to comply with the requirements of Standard No. 205. No manufacturer or dealer is permitted to install Contra Vision on the glazing materials on new vehicles, unless the manufacturer or dealer certifies that the vehicle continues to comply with the 70 percent minimum light transmittance and other requirements of Standard No. 205. After a vehicle is first sold to a consumer, modifications to the vehicle are affected by section 108(a)(2)(A) of the Safety Act (15 U.S.C. 1397(a)(2)(A)). That section prohibits any manufacturer, dealer, distributor, or repair business from "rendering inoperative" any device or element of design installed in a vehicle in compliance with any safety standard. This provision of the law means that no manufacturer, dealer, distributor, or repair business could install Contra Vision if the addition of Contra Vision to the glazing would result in a light transmittance of less than 70 percent, or otherwise cause the vehicle to no longer comply with the applicable requirements of Standard 205. Violations of this "render inoperative" prohibition can result in Federal civil penalties to the manufacturer, dealer, distributor, or repair business of up to $1000 for each noncomplying installation. Section 108(a)(2)(A) of the Safety Act does not affect vehicle owners. Hence, vehicle owners themselves may install Contra Vision or any other product on the glazing of their vehicle, regardless of whether the installation causes the vehicle to no longer comply with Standard No. 205. Individual States have the authority to regulate the operational use of vehicles by their owners, and, therefore, have the authority to regulate or preclude individual owner modifications to the glazing of their vehicles. I have enclosed an information sheet that summarizes the relationship between Federal auto safety laws and motor vehicle window tinting. I hope this information is helpful. If you have any further questions or need any additional information about this topic, please feel free to contact Dorothy Nakama of my staff at this address or by telephone at (202) 366-2992.

Mr. Doug Cole Director of Public Relations and Membership National Van Conversion Association, Inc. 2 West Main Street, Suite 2 Greenfield, IN 46140
Dear Mr. Cole:
Thank you for your letter of December 2, 1985 to Stephen Oesch of my staff concerning how our regulations would affect the placement of a national Van Conversion Association (NVCA) certification decal on vehicle windows by a van conversion company. The material enclosed with your letter explains that the NVCA certification program is a voluntary effort by the van conversion industry to set minimum safety and quality standards for its products. You explained that the decal, which has a diameter of 2 1/2 inches, would be placed on the lower corner of the passenger's side of the windshield by a manufacturer whose products conform to the NVCA program. Placement of the decals on a vehicle's windshield would be affected by Federal Motor Vehicle Safety Standard No. 205, Glazing Materials, which specifies performance and location requirements for glazing used in vehicles. These requirements include specifications for minimum levels of light transmittance (70% in areas requisite for driving visibility, which includes the windshield in motor vehicles).
Part 567, Certification, of our regulations requires each vehicle manufacturer to place a plate within the vehicle certifying that the vehicle conforms to all applicable Federal motor vehicle safety standards. A person, such as a van converter, who makes significant modifications to a vehicle prior to its first sale to a consumer is considered a vehicle alterer under our regulations. Under Part 567.7, an alterer must also add a plate to the vehicle certifying that the vehicle, as altered, still continues to conform to all applicable Federal motor vehicle safety standards. Thus, no manufacturer or alterer is permitted to install solar films and other sun screening devices or other opaque materials in new vehicles without certifying that the vehicle continues to be in compliance with the light transmittance and other requirements of the standard.
After a vehicle is first sold to a consumer, modifications to a vehicle are affected by section 108 (a) (2) (A) of the Vehicle Safety Act. That section prohibits commercial businesses from tampering with safety equipment installed on a vehicle in compliance with our standards. Thus, no dealer, manufacturer, repair business or distributor can install a sun screen device or other opaque material for the owner of the vehicle, if the device would cause the window not to meet the requirements of Standard No. 205. Violation of section 108 (a) (2) (A) can result in Federal civil penalties of up to $1,000 for each violation.
We have not previously ruled on whether these prohibitions apply to the installation of State vehicle inspection and private industry regulatory decals by commercial businesses. In general, these decals are small in size and placed in locations which minimize the obstruction, if any, to the driver's vision. In contrast, tinting films and other sun screening devices are generally applied to the entire window and thus can substantially obscure the driver's vision if they do not meet the light transmittance and other performance requirements of the standard. As with State regulatory decals, your proposed decal is small in size and would be placed in the lower right corner of the vehicle windshield, an area which should minimize any possible obstructing of the driver's vision. Given these considerations, we would consider the placement of the NVCA decal in the lower right hand corner of the windshield to be merely a technical violation of Standard No. 205, and would exercise our prosecutorial discretion and not bring an enforcement action. I hope this information is of assistance to you. If you have any further questions, please let me know.
Sincerely,
Erika Z. Jones Chief Council
December 2, 1985
Mr. Steve Oeshe NHTSA, Office of the Chief Council 400 7th Street South West Washington, D.C. 20590
Dear Steve:
Will you please provide me a written statement, from your department, that the placement of our Certification decals are not in violation of any Federal Safety Standards?
I have enclosed a rough drawing showing the placement of the decal, on the inside lower passenger side of the windshield. Also enclosed is our information packet about National Van Conversion Association's Van Conversion Manufacturer Certification program. If you have any questions about the program, or if I can be of service, please call on me.
Sincerely,
Doug Cole Director of P.R. and Membership
