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. Fairchild:

This responds to your request for my opinion of whether a particular vehicle (the Pinzgauer) would be considered a "motor vehicle" for the purposes of the National Traffic and Motor Vehicle Safety Act. When NHTSA previously considered this question, we stated in a March 25, 1982 letter to Mr. Leonard Fink that the Pinzgauer would be considered to be a motor vehicle, based on the information that was available to the agency at that time. However, that letter also stated that the agency would be willing to reconsider this conclusion if additional information were provided regarding the vehicle's marketing, advertising, and actual use. Your recent letter set forth three additional factors that you suggested might lead the agency to change its previous conclusion that the Pinzgauer was a motor vehicle. As explained in detail below, this agency reaffirms the previous conclusion that the Pinzgauer appears to be a motor vehicle.

Section 102(3) of the Safety Act (15 U.S.C. 1391(3)) defines a "motor vehicle" as

any vehicle driven or drawn by mechanical power manufactured primarily for use on the public streets, roads, and highways, except any vehicle operated exclusively on a rail or rails.

NHTSA has interpreted this language as follows. Vehicles that are equipped with tracks or are otherwise incapable of highway travel are plainly not motor vehicles. Further, vehicles designed and sold solely for off-road use (e.g., airport runway vehicles and underground mining devices) are not considered motor vehicles, even though they may be operationally capable of highway travel. Vehicles that have an abnormal body configuration that readily distinguishes them from other highway vehicles and a maximum speed of 20 miles per hour (mph) are not considered motor vehicles, because their use of the public roads is intermittent and incidental to their primary intended off-road use. On the other hand, vehicles that use the public highways on a necessary and recurring basis are motor vehicles. For instance, a utility vehicle like the Jeep is plainly a motor vehicle, even though it is equipped with special features to permit off-road operation. If a vehicle's greatest use will be off-road, but it will spend a substantial amount of time on-road, then NHTSA has interpreted the vehicle to be a "motor vehicle". Further, the agency has determined that a vehicle such as a dune buggy is a motor vehicle if it is readily usable on the public roads and is in fact used on the public roads by a substantial number of owners, regardless of the manufacturer's stated intent regarding the terrain on which the vehicle is to be operated.

Vehicles such as the Pinzgauer are not easily classified under either of these groupings. On the one hand, the Pinzgauer is obviously designed to have substantial off-road capabilities, as evidenced by high ground clearance, deep water fording capabilities, and all-wheel drive. According to its manufacturer, 95 percent of the annual production of Pinzgauers is purchased by armed forces worldwide. These factors suggest that the Pinzgauer should not be classified as a motor vehicle. On the other hand, the available information shows the Pinzgauer is suitable for use on-road. The vehicle has a top speed of nearly 70 miles per hour. Page 4 of Enclosure 1 of your letter shows that the Pinzgauer is equipped with turn signals and states that the power steering minimizes steering effort "both in difficult terrain and when parking." Page 4 of Enclosure 3 with your letter describes the serviceability of the Pinzgauer "with ordinary on- and off-road usage." These factors suggest that the vehicle is designed and intended to be routinely used on the public roads, which suggests that it should be classified as a motor vehicle.

In instances where the agency is asked whether something is a motor vehicle, when the vehicle has both on-road and off-road operating capabilities, and about which there is little or no evidence about the extent of the vehicle's on-road use, NHTSA has applied five factors to reach its conclusion. These factors are:

1. Whether States or foreign countries have permitted or are likely to permit the vehicle to be registered for on-road use.

2. Whether the vehicle is or will be advertised for use on-road as well as off-road, or whether it is or will be advertised exclusively for off-road use.

3. Whether the vehicle's manufacturer or dealers will assist vehicle purchasers in obtaining certificates of origin or title documents to register the vehicle for on-road use.

4. Whether the vehicle is or will be sold by dealers also selling vehicles that are classified as motor vehicles.

5. Whether the vehicle has or will have affixed to it a warning label stating that the vehicle is not intended for use on the public roads.

When NHTSA previously considered whether the Pinzgauer should be considered a motor vehicle, the available information regarding these factors showed that the manufacturer had equipped the vehicle with side marker lights, the manufacturer expected the vehicle to be used on-road, and that it would be sold by dealers that also sell vehicles that are clearly motor vehicles.

In your letter, you enclosed some additional information and brochures from the manufacturer that show the manufacturer continues to expect Pinzgauers to be used both on- and off-road. Since the manufacturer does not now expect to sponsor the vehicle's sale in the U.S., no information is available on the anticipated dealers. The additional information enclosed with your letter did not specifically address any factors on which no information was previously available to NHTSA. Hence, the agency has no basis for changing its previous conclusion that the Pinzgauer appears to be a motor vehicle.

You suggested three reasons that might lead the agency to reverse its previous conclusion. First, you suggested that the 6-wheeled version of the Pinzgauer has a unique body configuration which distinguishes it from typical, on-road vehicles and makes it particularly well suited to off-road use. You correctly noted that the agency's 1982 letter addressed both the 4-wheeled and 6-wheeled version of the Pinzgauer. However, for the purposes of this analysis, there is no attribute of the 6-wheeled version that would lead the agency to conclude that it should be classified differently than the 4-wheeled version of the Pinzgauer. Many vehicles that are clearly motor vehicles have 6 wheels. In all other respects, the 4- and 6-wheeled Pinzgauers have similar on-road capabilities, including a top speed of more than 65 miles per hour.

Second, you suggested that NHTSA concluded that the Unimog is not a "motor vehicle" in a February 7, 1984 letter, and that the Unimog and Pinzgauer are comparable vehicles. In the February 7, 1984 letter to Mr. Karl-Heinz Faber to which you refer, NHTSA stated that it had no basis for changing its previous conclusion that the Unimog was not a "motor vehicle." NHTSA also noted that this conclusion was based upon the assumptions that Unimog vehicles would continue to be marketed through dealers of farm machinery and heavy equipment and that Unimog vehicles would have a label affixed stating that the Unimog is not manufactured for highway use. In other words, the information available for Unimog (especially regarding factors number 4 and 5 above) was sufficient to lead the agency to conclude that it was not a motor vehicle, even though Unimogs are operationally capable of on-road use. By way of contrast, either no information is available for Pinzgauer vehicles regarding the five factors identified above or, if information is available for a factor, it suggests that the Pinzgauer should be treated as a motor vehicle. Since the Pinzgauer is operationally capable of on-road use, and there is no indication that the manufacturer does not intend for it to spend a substantial amount of time on-road, NHTSA reaffirms its previous statement that these vehicles appear to be "motor vehicles," within the meaning of the Safety Act.

Third, you suggested that NHTSA's 1982 conclusion did not include a consideration of the primary design intent of the Pinzgauer for military purposes and the high percentage of its total sales to the military. NHTSA's 1982 conclusion and this reconsideration both are addressed only to the non-military versions of the Pinzgauer. The military versions of the Pinzgauer would not be subject to the safety standards if their sales satisfied 49 CFR 571.7(c). In both the 1982 and this examination of whether the non-military versions of the Pinzgauer are motor vehicles, the agency fully considered the substantial off-road capabilities of these vehicles. However, absent indications that the manufacturer does not intend the Pinzgauer to spend substantial periods of time on-road, NHTSA concluded in 1982, and reaffirms at this time, that the non-military versions of the Pinzgauer appear to be "motor vehicles" within the meaning of the Safety Act.

I hope this information is useful. If you have any further questions or need some additional information on this topic, please feel free to contact Steve Kratzke of my staff at this address or by telephone at (202) 366-2992.

Paul Jackson Rice Chief Counsel

TITLE: FMVSR INTERPRETATION

TEXT: This is in reply to your letter of April 2, 1973, regarding the classification of the Volkswagen Model 181 (The VW Thing) for purposes of the Federal Motor Vehicle Safety Standards.

Based on a review of your letter and its enclosures, we accept your classification of the Model 181 as a Multipurpose Passenger Vehicle.

Francis Armstrong, Director National Highway Traffic Safety Administration

Re: N41-22GSh

This is in response to your letter of March 19, 1973 directed to Mr. Crawford Shaw in which you requested the submission of satisfactory evidence that would support our classification of the Volkswagen Model 181 (The VW Thing) as a Multipurpose Passenger Vehicle.

Upon receipt of your letter, we arranged for a meeting with you and your staff which was held in your office on March 29, 1973. At this meeting, we presented information relevant to the fact that the VW model 181 is equipped ". . . . with special features for occasional off-road operations . . . . " as is required by the definition of a Multipurpose Passenger Vehicle. The following submission enumerates the features of the VW 181.

VEHICLE HISTORY

This vehicle was originally designed in the early 1960's under contract for the German Government. A major consideration in the design concept was the requirement by the army for rough terrain operation and associated vehicle specifications. The availability of the vehicle was originally limited to the army but subsequently, after sufficient production capacity was gained, availability was extended to the general public in Europe. Most recently, the entire world production has been centralized in Mexico and vehicles are exported back to Europe and also now to the U.S.A.

2

VEHICLE FEATURES

The following is a description of the vehicle including a comparison in some respects to our VW Beetle models so as to differentiate between typical passenger car specifications.

The BODY DESIGN is both rugged and functional, void of cosmetic details, with maximum consideration given to the extremes of hard usage found off road rather than to comfort and decor. The sloping front hood provides excellent forward visibility, an aid in negotiating hill crests. Generous clearance between the fenders and the tires is provided for accommodating extreme suspension travel and preventing entrapment of foreign objects. A folding soft top, removable side curtains and a folding windshield provide for operation in extremes of weather and possibly for negotiating areas of minimal overhead clearance. The folding feature of the rear seats provide a compartment of seventeen cubic feet capacity for cargo carrying.

Special off-road features are:

1. Standard tires of 185 R 14 M & S (Mud and Snow) with tube mounted to a five inch wide rim. The coarse tread profile provides versatility on all surface types. This compares to our normal Beetle tire of 6.00x150, tubeless, mounted to a 4 1/2 inch rim.

2. Ground clearance of 8.1 inches as compared to normal Beetle dimension of 5.9". For additional comparison our VW 412 model has a ground clearance of 5.3" and typical domestic models average approximately 5.0". Ground clearance of competitive off-road vehicles is in the range of 7 to 8".

3. Angle of Approach of 36 degrees and Angle of Departure of 31 degrees gives favorable grade negotiating ability without interference in the area of the vehicle overhang. For both domestic and import passenger cars, the angle of approach is in the range of 17 degrees to 25 degrees and the angle of departure from 11 degrees to 21 degrees.

3

4. An additional specification, unique to this model, is the "Wading or Fording Depth" which is 15.6 inches. This dimension constitutes the water depth through which this vehicle can be driven without danger. Typical passenger cars are not capable of such activity nor is such a dimension specified.

5. An engine protection shield is provided under the vehicle to minimize the chance of damage in the lower crankcase area. Also, an additional shield is provided for the Exhaust Gas Pecirculation filter, a part of the emission control system provided for the U.S.A. model.

6. Towing eyes are provided, mounted in the bumper, two front and two rear, for attachment of a tow line.

7. The overall Transmission/Final Drive gear ratios are lower as compared to the Beetle for improved low speed performance. Hill climbing ability is approximately 15% improved over that of the Beetle, measured on a paved roadway.

8. The chassis employed is a derivative of our platform design, however, reinforcement in the area of the suspension mounting is added. Reinforcement struts from the front torsion tubes to the chassis prevent damage in high load conditions. The front and rear axle loads are respectively 1212/1764 lb. as compared to 1080/1609 lb. of the Beetle.

9. The engine equipped is identical to that of our Beetle model except for minor changes in emission control techniques. However, the air cleaner is a very large capacity oil bath type which aids in reducing dust intake in off-road activities.

Enclosed for your information is a List of Technical Specifications (Exhibit 1) and a copy of the Owner's Manual (Exhibit 2) for the U.S.A. model 181.

In our meeting with you, some discussion centered around the providing of four-wheel drive in an off-road vehicle. In the VW 181 with its low curb weight (1995 lb.), rear weight bias, and four-wheel independent suspension, we find no need for four-wheel drive. In our own comparative research, we have in some instances found the 181 to have a distinct advantage over other, much heavier, four-wheel drive vehicles. Also, it is interesting to note that vehicles such as the Chevrolet Blazer, IHC Scout and the Jeep DJ-5 are available with two wheel drive standard and four-wheel drive optional at extra cost.

Additionally of interest, the National Off Road Racing Association (NORRA) is a sanctioning body of many off road race events in the U.S., including that taking place in the Baja area of Lower California. They have clearly recognized the respective capabilities of both two wheel and four wheel drive vehicles by providing competitive classes for both.

Enclosed is a copy of an article that was published in the March 1973 issue of MOTOR TREND Magazine (Exhibit 3). The thoughts of the writers illustrate the capabilities of the vehicle and only illuminate the enthusiasm that has been and will be generated by this vehicle inthe off-road, recreational vehicle market.

In a report of the National Traffic Safety Agency on the development of the initial Federal Motor Vehicle Safety Standard published in Washington, D. C. on March 17, 1967, the Agency set forth the history of its standard setting process and the specific considerations that entered into the selection of the options that were ultimately incorporated into the law. As in many other standard areas, the Agency felt that a number of options were open to it in dealing with the problems presented by special purpose vehicles. The report of March 17 records the discussions within the Agency (Exhibit 4).

It is fair to conclude, in our opinion, that by introducing the definition of MPV, the Agency recognized that some passenger type vehicles present special problem in meeting the passenger car standards and should, therefore, not be required to comply with all of them. The report also makes it clear that the Agency is thinking primarily of jeep and van type vehicle that would fall into that category since both are essentially used as passenger cars but have also features that make them suitable for "carrying of goods" or "cross-country travel over rough terrain."

5

You have also requested clarification of the text of the certification label. We have been informed by the factory that the label text does contain the proper reference to "Gross Axle Weight Rating" and "Gross Vehicle Weight Rating". We do not have a sample of the actual certification label at this time, but will forward one to you shortly. For reference at this time, page two of the enclosed Owner's Manual contains a facsimile of the certification label as it will appear in the vehicle.

In conclusion, the facts set forth herein firmly support our classification of the VW model 181 as a Multipurpose passenger vehicle, in that it is equipped with special features for occasional off-road operations. Competitive vehicles, as Jeeps, Land Rovers, and Broncos may be slightly different from the model 181 in their configurations and offer four wheel drive as an extra cost option, but are very much identical to the model 181 in terms of performance and suitability for off-road use.

We look forward to receiving your early reply and extend the invitation to completely examine an actual vehicle, at your convenience, at our facility in Englewood Cliffs. If any additional questions should arise, please contact me directly by telephone at the number below.

Sincerely yours,

Guenter Storbeck

Vehicles that have an abnormal body configuration that readily distinguishes them from other highway vehicles and a ma ximum speed of 20 miles per hour (mph) are not considered motor vehicles, because their use of the public roads is intermittent and incidental to their primary intended off-road use.

On the other hand, vehicles that use the public highways on a necessary and recurring basis are motor vehicles.

The vehicle has a top speed of nearly 70 miles per hour. Page 4 of Enclosure 1 of your letter shows that the Pinzgauer is equipped with turn signals and states that the power st eering minimizes steering effort "both in difficult terrain and when parking." Page 4 of Enclosure 3 with your letter describes the serviceability of the Pinzgauer "with ordinary on- and off-road usage." These factors suggest that the vehicle is design ed and intended to be routinely used on the public roads, which suggests that it should be classified as a motor vehicle.

In instances where the agency is asked whether something is a motor vehicle, when the vehicle has both on-road and off-road operating capabilities, and about which there is little or no evidence about the extent of the vehicle's on-road use, NHTSA has ap plied five factors to reach its conclusion. These factors are:

1. Whether States or foreign countries have permitted or are likely to permit the vehicle to be registered for on-road use.

2. Whether the vehicle is or will be advertised for use on-road as well as off-road, or whether it is or will be advertised exclusively for off-road use.

3. Whether the vehicle's manufacturer or dealers will assist vehicle purchasers in obtaining certificates of origin or title documents to register the vehicle for on-road use.

4. Whether the vehicle is or will be sold by dealers also selling vehicles that are classified as motor vehicles.

5. Whether the vehicle has or will have affixed to it a warning label stating that the vehicle is not intended for use on the public roads.

When NHTSA previously considered whether the Pinzgauer should be considered a motor vehicle, the available information regarding these factors showed that the manufacturer had equipped the vehicle with side marker lights, the manufacturer expected the ve hicle to be used on-road, and that it would be sold by dealers that also sell vehicles that are clearly motor vehicles.

In your letter, you enclosed some additional information and brochures from the manufacturer that show the manufacturer continues to expect Pinzgauers to be used both on- and off-road. Since the manufacturer does not now expect to sponsor the vehicle's sale in the U.S., no information is available on the anticipated dealers. The additional information enclosed with your letter did not specifically address any factors on

which no information was previously available to NHTSA. Hence, the agency has no basis for changing its previous conclusion that the Pinzgauer appears to be a motor vehicle.

You suggested three reasons that might lead the agency to reverse its previous conclusion. First, you suggested that the 6-wheeled version of the Pinzgauer has a unique body configuration which distinguishes it from typical, on-road vehicles and makes i t particularly well suited to off-road use. You correctly noted that the agency's 1982 letter addressed both the 4-wheeled and 6-wheeled version of the Pinzgauer. However, for the purposes of this analysis, there is no attribute of the 6-wheeled versio n that would lead the agency to conclude that it should be classified differently than the 4-wheeled version of the Pinzgauer. Many vehicles that are clearly motor vehicles have 6 wheels. In all other respects, the 4- and 6-wheeled Pinzgauers have simi lar on-road capabilities, including a top speed of more than 65 miles per hour.

Second, you suggested that NHTSA concluded that the Unimog is not a "motor vehicle" in a February 7, 1984 letter, and that the Unimog and Pinzgauer are comparable vehicles. In the February 7, 1984 letter to Mr. Karl-Heinz Faber to which you refer, NHTSA stated that it had no basis for changing its previous conclusion that the Unimog was not a "motor vehicle." NHTSA also noted that this conclusion was based upon the assumptions that Unimog vehicles would continue to be marketed through dealers of farm machinery and heavy equipment and that Unimog vehicles would have a label affixed stating that the Unimog is not manufactured for highway use. In other words, the information available for Unimog (especially regarding factors number 4 and 5 above) was s ufficient to lead the agency to conclude that it was not a motor vehicle, even though Unimogs are operationally capable of on-road use. By way of contrast, either no information is available for Pinzgauer vehicles regarding the five factors identified a bove or, if information is available for a factor, it suggests that the Pinzgauer should be treated as a motor vehicle. Since the Pinzgauer is operationally capable of on-road use, and there is no indication that the manufacturer does not intend for it to spend a substantial amount of time on-road, NHTSA reaffirms its previous statement that these vehicles appear to be "motor vehicles," within the meaning of the Safety Act.

Third, you suggested that NHTSA's 1982 conclusion did not include a consideration of the primary design intent of the Pinzgauer for military purposes and the high percentage of its total sales to the military. NHTSA's 1982 conclusion and this reconsidera tion both are addressed only to the non-military versions of the Pinzgauer. The military versions of the Pinzgauer would not be subject to the safety standards if their sales satisfied 49 CFR S571.7(c). In both the 1982 and this examination of whether the non-military versions of the Pinzgauer are motor vehicles, the agency fully considered the substantial off-road capabilities of these vehicles. However, absent indications that the manufacturer does not intend the Pinzgauer to spend substantial peri ods of time on-road, NHTSA concluded in 1982, and reaffirms at this time, that the non-military versions of the Pinzgauer appear to be "motor vehicles" within the meaning of the Safety Act.

I hope this information is useful. If you have any further questions or

need some additional information on this topic, please feel free to contact Steve Kratzke of my staff at this address or by telephone at (202) 366-2992.

Dear Ms Sizemore:

This is in reply to your letter of March 18, 1998, regarding a lamp you are considering manufacturing.

We understand from a conversation that Taylor Vinson of this Office had with your husband on April 16, 1998, that the lamp is intended to illuminate in a steady-burning fashion when the brake pedal is applied, and that it will be red in color. The lamp will fit in a spoiler or wing installed on the back of a car. As you note, aftermarket companies have been installing these in spoilers for some time, and we understand from your husband that aftermarket sales are intended both to new car dealers and to parts supplies stores. You believe that "this light may not need to be D.O.T. approved based on the intended application, however our customer requires that the light be D.O.T. approved."

The Department has no authority to "approve" or "disapprove" items of equipment, nor are there any "D.O.T. licensing requirements," the subject of three of your questions. We do advise whether supplementary lighting equipment such as your lamp appears permitted or prohibited by the Federal motor vehicle safety standard on lighting, Standard No. 108 Lamps, Reflective Devices and Associated Equipment.

I enclose a copy of a letter to Timothy McQuiston, dated January 28, 1994, which discusses the relationship to Federal laws of aftermarket spoilers incorporating stop lamps. If you or your husband have any questions, you may call Taylor Vinson (202-366-5263). As he explained, the direct obligations under Federal law fall upon those persons who install the spoiler-lamp, rather than on those who manufacture or sell it. Nevertheless, your company can help the installer fulfill his obligation by ensuring that the lamp in the spoiler complies with Standard No. 108, principally in ensuring that it has a minimum lens area of 4 1/2 square inches and meets the appropriate photometrics.

In addition to the letter to Mr. McQuiston, we are also enclosing a copy of the sections of Standard No. 108 that apply to lamps in spoilers that serve as the required center highmounted stop lamp. These are paragraph S5.1.1.27 and Figure 10.

Sincerely,
John Womack

Dear Mr. Suzuki:

This is in reply to your letter concerning the testing of reflectors of replaceable lens headlamps for chemical and corrosion resistance. I apologize for the delay in our response.

Under the test procedure established by S8.10.1(c), after test fluids are applied to headlamp reflectors, the reflectors "shall be wiped clean with a soft cotton cloth . . . ." You remark that the force applied to the reflector during cleaning is not specified, noting that if Stanley wipes the reflector "so gently that the surface would not be damaged, the headlamp will meet the requirements prescribed in S7.4(h)(2)," but, "on the other hand, if we wipe the reflector without any carefulness, the surface might be damaged." In your opinion, this means that "some kind of attention is needed to meet the requirement of S7.4(h)(2)." You ask "if such kind of attention is permitted under S8.10.1(c)."

S5.8.11 of Standard No. 108 requires that a replacement lens for a replaceable lens headlamp must be provided with a replacement seal in a package "that includes instructions for the removal and replacement of the lens, the cleaning of the reflector, and the sealing of the replacement lens to the reflector assembly." Although you reference only the chemical resistance test of S8.10.1(c), we note that the corrosion test contains a specific requirement that "the reflector shall be cleaned according to the instructions supplied with the headlamp manufacturer's replacement lens" (S8.10.2(b)). The instructions for the cleaning of the reflector may specify the force recommended to be applied for this operation.

If the instructions do not specify the force needed to wipe the reflector clean, we would interpret the test procedure as encompassing the range of force levels that technicians would reasonably employ to perform the required task. Thus, in a compliance test where instructions are silent as to the force to be used, no special care would be taken to use the minimum possible force, nor would the technician deliberately use excessive force.

Frank Seales, Jr.

Dear Mr. Bol:

This is in reply to your January 1998 letter to the Department informing us of your V.E.B. System, and stating that "it remains to you the decision to commercialize this product in co-operation with us."

You are interested in marketing this system "with an auto-manufacturer." Therefore, you intend the V.E.B. system to be installed as original equipment on motor vehicles manufactured for sale in the United States. The system may be best described as a center highmounted stop lamp that displays a vehicle's registration number under ordinary circumstances and the word "stolen" when the vehicle is being operated without the owner's authority.

The center highmounted stop lamp must comply with all requirements of United States Federal Motor Vehicle Safety Standard No. 108. One of these requirements is that the lamp comply with the requirements of Figure 10. This Figure prescribes minimum and maximum candela to be measured at 18 individual test points. If any one of these test points is obscured by the vehicle's registration number or the word "stolen," then it is not legal to install the lamp on a motor vehicle. We believe that it might be difficult to design a lamp that both displays the information you anticipate and meets Standard No. 108. I enclose a copy of Figure 10 so that you may determine whether any of the 18 test points may be obscured by the V.E.B. system. A second requirement is that the lens area must be at least 4.5 square inches. Any obstruction would affect this, too.

Standard No. 108 also prohibits the installation of any device that impairs the effectiveness of required lighting equipment such as the center stoplamp. Even if the candela and lens area requirements are met, the clarity and meaning of the stop signal may be undermined by letters or numbers appearing when the lamp is lit that have no relation to the stop lamp function.

The Department has no authority to engage in commercial promotions with manufacturers, and we cannot help you with this product.

Finally, we would like to call your attention to a typographical error on the cover and interior of your sales folder. The verb indicating theft in English is "to steal," not "to steel."

John Womack

TEXT:

June 28, 1985 Mr. H. Moriyoshi Executive Vice President and General Manager Mazda (North America), Inc. 24402 Sinacola Court Farmington Hills, Michigan 48018 Dear Mr. Moriyoshi: This is in reply to your letter of June 3, 1985, asking for an interpretation of Motor Vehicle Safety Standard No. 108 regarding requirements for the center high-mounted stop lamp/ You reference an agency letter of July 30, 1980, to Volkswagen of America in which the Chief Counsel concluded that placement of the stop lamps and taillamps on the deck lid could be viewed as a defect in performance requiring notification and remedy. You have asked, in essence, how this related to Standard No. 108's present allowance of a center high-mounted stop lamp mounted on a vehicle's decklid, hatch, or tailgate. The assumption underlying the agency's 1980 letter was that a defect could exist if all a vehicle's stop lamps and taillamps were mounted on the decklid, where their signals could be unobserved or obscured if the lid were in any position other than closed. The center high-mount stop lamp, on the other hand, while an item of required equipment, is nevertheless a supplementary stop lamp. Even if the deck, hatch, or tailgate upon which it is mounted should be open, following drivers may still observe the signals of the primary stop lamps remaining on the body. You have asked that we also discuss the implications of a stop lamp and taillamp constructed so that a portion is fixed to the body of the vehicle adjacent to the decklid opening and the remaining portion is mounted on the outboard area of the decklid. Compliance of a vehicle is determined with respect to its normal driving position, that is to say, with the tailgate, hatch, or decklid closed. However, in order to obviate any possibility of the existence of a safety-related defect, we recommend that the portion of the lamp that is mounted on the body itself comply with the minimum requirements of Standard No. 108 for a single compartment stop lamp or taillamp. I hope that this answers your questions. Sincerely, Original Signed by Jeffrey R. Miller Chief Counsel

ATTACHMT: LETTER DATED 03/19/90 FROM SHUICHI WATANABE TO ERIKA Z. JONES -- NHTSA; OCC 4549

TEXT: This is in reply to your letter of March 19, 1990, asking whether a new combination rear lamp is permitted under Motor Vehicle Safety Standard No. 108.

The lamp consists of three compartments. In its normal operating mode, when the taillamp and/or stop lamp are activated, all three compartments show a red light. Your question arises with respect to three different operating modes. The first occurs whe n the turn signal is activated; the red light in one of the compartments is replaced by an amber flashing one. The second occurs when the backup lamp is activated; the red light in another of the compartments is replaced by a white steady-burning one. The third occurs when both the backup lamp and turn signal are activated; in this event, the combination lamp would present an amber flashing light, a red steady-burning one, and a white steady-burning one. You have informed us that "the requirement of photometric and lighted area for each lamp function comply to FMVSS No. 108 and related comply with requirements for one and three compartment lamps when operating with one or three compartments (we assume that they would also meet the requirements for t wo compartment lamps).

The lamp appears to be intended to fulfill the requirements of Standard No. 108 for turn signal, stop, tail, and backup lamps. Thus, your question appears to be whether Standard No. 108 requires separate lamps or compartments dedicated to a specific pur pose, or whether your multiple purpose lamp is acceptable.

Standard No. 108 does not prohibit a combination of the functions that any chamber of your lamp provides. When a specific function is activated, the lamp will perform that particular function in a manner that appears to meet the minimum standard establi shed by Standard No. 108. Assuming that the CIE color definitions for white, amber, and red are met by the backup, turn, and stop/tail functions, the lamp appears to be permissible under Standard No. 108.

ATTACHMT: LETTER DATED 04/22/88 TO ERIKA Z JONES, FROM PAUL SCULLY RE INTERPRETATION OF EFFECTIVE PROJECTED LUMINOUS AREA, OCC - 1946

TEXT: Dear Mr. Scully:

This is in reply to your letter of April 22, 1988, asking for a clarification of a letter that this Office sent Wesbar Corporation on March 16, 1988, with respect to the term "effective projected luminous area."

Wesbar had asked whether it could include the "illuminated (by the turn signal bulb) reflex reflector portion of the turn signal lens" (Wesbar's language) in its calculation of the 12 square inch minimum effective projected luminous area required by S4.1 .17 of Safety Standard No. 108. We replied that it could, assuming that the light shines through the reflector. You have pointed out that although a small amount of light escapes through a reflex reflector, the reflector is designed to return light fro m an outside source, rather than to direct light from a source inside the lamp, and that heretofore agency interpretations (e.g. on October 28, 1970, and October 28, 1979) had expressly excluded reflex reflectors from areas included in the calculation of effective projected luminous area. Reflex reflectors are also excluded from the term by SAE J387 Terminology.

We appreciate your calling this matter to our attention. Previous interpretations by this Office clearly indicate that a "reflex reflector" is not to be included in the calculation of effective projected luminous area. We also note that the SAE definit ion (paragraph 2, SAE J594f,

January 1977) is incorporated by reference into Standard No. 108, stating that this item of equipment is one that provides an indication of vehicle presence by reflected light (rather than projected light). We are providing a copy of this letter to Wesbar so that it will be apprised of our reevaluation, and our conclusion that the reflex reflector portion of a lens cannot be included in the calculations of the projected luminous lens area.

I hope this clarifies the matter for you.

Sincerely,
