TEXT: We spoke with Dorhy Nakama of your office on June 23, 1994 and again on Tuesday, June 28, 1994. She was very helpful in obtaining information that will allow us to re-classify our Traffic Control Attenuator vehicles. In following the fax of June 28, 19 94 we will attempt to highlight the paragraphs that we believe applies to our specific operations regarding the remanufacturing process. We will supply a brief description of this process as well as describe the vehicles and show pictures.

I. We manufacture between 15 to 18 vehicles per year. Below are photographs of our completed Traffic Control Attenuating vehicles which are totally dedicated to this use.

A) 1977 Chevy Titan, COE, Tandem Axle, 6 cyl. Diesel Engine, 9 spd Transmission, Road Tractor. Combined GVW 80,000# or Single GVW 45,000#. Photo #1 (page 3) shows in the transport/travel mode.

(1) During Remanufacturing:

(a) Truck 5th Wheel or body is removed and scraped.

(b) All air lines and brake systems used in the trailer towing operation are removed and lines are plugged. (will not be needed or reused)

(c) All Sub-frame, brakes, remaining brake lines, engine drive line, rear suspension, and axles are checked. Any items needing repair are repaired and/or replaced.

(d) Steering systems and shocks are checked and are repaired or replaced if needed.

(e) Frame and all running gear is cleaned, prime painted, and finish painted.

(f) A new support frame and truck mounted Attenuator mounting hardware with braces is then installed.

(g) A new Pre-cast concrete counter weight is installed that will bring the completed vehicle to its new GVW of +/- 25,500# and not to exceed 25,999#.

(h) New rear lighting, heavy duty safety lights, and reflectors are then installed in accordance with Federal Motor Vehicle Safety Standards.

(i) A new Advanced Warning Flashing Arrow (4' x 8') sign is installed along with (3) 4D batteries or (6) Deep cycle batteries, a solar battery charging system, and a electronic controller inside the truck cab are installed.

(j) Final installation of Vehicle Attenuation cushion and lift/tilt hydraulics.

(k) Unit is painted if required and then placed in service (lease/purchase) or sold.

(B) 1979 Peterbilt same as Titan except shows Vehicle Attenuating Device in highway operation mode. Photo #2 (page 3)

II. Under 49 CFR ChV (10-1-93 Edition) on (Page 172), we fall within subparagraph (e) combining New and Used components manufacturing; and part of (f) Combining New and Used components in trailer manufacturing (1) & (2).

III. In your letter to John Paul Barber, Esq. (Copy attached) we find that our situation is similar. However, our truck with an original GVW of 45,000# or 80,000# when the unit was constructed. All that we require to meet state specifications is (20,0 00# to 24,000# GVW)

All these vehicles are subject to sales and use taxes if rented, leased or sold and amount is subject to total value.

IV. We are requesting that if you review our re-manufacturing operation as we described along with the photographs we would request that you issue us a ruling similar to those of the other letters. We will, if approved, supply the new Supplementary Vin Plate showing Mfg. Name, Date of Mfg., Vehicle Make and Model, Original Mfg. Vin Number, and NEW Actual GVW. This plate will be attached below the original Vin Plate.

TITLE: Request for Interpretation of Federal Motor Vehicle Safety Standards

ATTACHMT: Attached to letter dated 7/6/94 from Larry L. Wessels to John Womack (A42; Stds 106)

TEXT: During the past several months we have been in communication with Dr. Gerald Steward of the National Highway Traffic Safety Administration. Dr. Stewart suggested in his letter dated April 18, 1994, that we provide you with pertinent safety and product i nformation regarding our new invention for a safety product, "Handi-Slide", for semitrailers equipped with sliding axle/undercarriage assemblies.

The "Handi-Slide" has the potential to reduce or eliminate existing safety problems as identified in the U.S. Department of Transportation 49 Code of Federal Regulations. Specific Code of Regulations are identified in our information booklet that is enc losed.

We have also enclosed a "Handi-Slide" video that shows and demonstrates the advantages of our pneumatic/air locking pin system compared to the present manual force pin removal system that has been in use since sliding undercarriages were introduced appro ximately 40 years ago. The state-of-the-art "Handi-Slide" system offers the trucking industry improved safety and increased operating efficiency compared to the old manual cantilever system that is currently in use.

We have installed "Handi-Slide" over-the-road test units on several semitrailers. We are receiving numerous favorable comments from truck owners, drivers and trailer manufacturer engineers regarding the "Handi-Slide" test units.

If you have any further questions, please contact us at (303)922-4518. We look forward to receiving your comments regarding our new invention. Thank you for your assistance in this matter.

ATTACHMT: Attached to letter dated 5/24/94 from Larry L. Wessels to John Womack (OCC-10032)

TEXT: This responds to your letter requesting an interpretation about the use of your product, the "Handi-Slide." You state that your invention is a locking system for securing and releasing a sliding semitrailer undercarriage. You further state that the syst em is tied into the trailer's air brake system. I am pleased to have this opportunity to explain our regulations to you.

By way of background, the National Highway Traffic Safety Administration (NHTSA) administers Federal requirements for the manufacture and sale of new motor vehicles and items of motor vehicle equipment. NHTSA does not provide approvals of motor vehicles or motor vehicle equipment. Instead, the National Traffic and Motor Vehicle Safety Act establishes a "self-certification" process under which each manufacturer is responsible for certifying that its products meet all applicable Federal motor vehicle sa fety standards (FMVSS's). This process requires each manufacturer to determine in the exercise of due care that its products meet all applicable requirements.

NHTSA tests vehicles and equipment sold to consumers for compliance with the FMVSS's and investigates defects relating to motor vehicle safety. If a manufacturer or NHTSA determines that a noncompliance or safety-related defect exists, the manufacturer must notify purchasers of its product and remedy the problem free of charge. (This responsibility is borne by the vehicle manufacturer in cases in which your product is installed on a new vehicle by the vehicle manufacturer.) A manufacturer of a noncomp lying product that is subject to an FMVSS is also subject to a civil penalty of up to $ 1,000 for each noncomplying item it produces. I have enclosed an information sheet that highlights the responsibilities of motor vehicle equipment manufacturers.

NHTSA does not have any specific FMVSS for semitrailer undercarriages. However, since the Handi-Slide is tied to a

2

vehicle's air brake system, your product could affect a vehicle's compliance with Standard No. 121, Air Brake Systems. That standard applies to new trucks, buses, and trailers equipped with air brake systems, and specifies performance and equipment requi rements for the braking systems on these vehicles. Your product could also affect the vehicle's compliance with Standard No. 106, Brake Hoses, which specifies requirements for the air brake hoses, fittings and assemblies on the vehicle.

If the Handi-Slide is installed as original equipment on a new vehicle, the vehicle manufacturer is required to certify that, with the device installed, the vehicle satisfies the requirements of all applicable safety standards, including Standards No. 12 1 and 106. If the device were added to a previously certified new motor vehicle prior to its first consumer purchase, then the person who modifies the vehicle would be an alterer of a previously certified motor vehicle and would be required to certify t hat, as altered, the vehicle continues to comply with all of the safety standards affected by the alteration.

If the Handi-Slide were installed on a used vehicle by a manufacturer, distributor, dealer, or motor vehicle repair business, then the installer would not be required to attach a certification label. However, S108(a)(2)(A) of the Safety Act requires the installer not to knowingly render inoperative, in whole or in part, any device or element of design installed on or in a motor vehicle or item of motor vehicle equipment in compliance with an applicable FMVSS. Section 108(a)(2)(A) does not apply to vehi cle owners modifying their own vehicles.

I note that you provide an attachment titled "Current NHTSA Locking Pin Safety Concerns" that references several Federal Motor Carrier Safety Regulations. Please note that these regulations are administered by the Federal Highway Administration (FHWA), n ot NHTSA. If you are interested in the FHWA requirements, you can write to that agency at the address provided in the enclosed information sheet.

I hope this information is helpful. If you have any questions about NHTSA's safety standards, please feel free to contact Marvin Shaw at this address or by telephone at (202) 366-2992.

ATTACHMT: Attached to letter dated 6/6/94 from Walter Lavis to John Womack (OCC-10080)

TEXT: We have received your letter of June 6, 1994, with respect to your "Saf-T-Flec" reflectors.

You say that you have been informed by a NHTSA representative that "using the standard DOT approved reflector tape would allow the use of my reflector for the trucking industry." Judging from the red, white, and amber samples you have enclosed, your "ref lectors" appear to be retroreflective tape which adheres to a semicircular aluminum base and is intended for vertical mounting on the side and back of vehicles. Several potential customers have asked whether your concept was "DOT approved", and you have asked for a reply.

The Department of Transportation has no authority to "approve" items of motor vehicle equipment. We advise inquires whether manufacture or use of any particular item of equipment is prohibited or permitted under the Federal motor vehicle safety standard s and associated regulations. However, if an item is deemed permissible, this must not be represented as "approval" by DOT.

Your letter is somewhat unclear as to the intended use and market for Saf-T-Flec. The fact that you have enclosed a highlighted copy of S5.1.1.4 leads us to believe that one application you envision for Saf-T-Flec is as a substitute for original equipme nt side reflex reflectors. This substitution is permitted if the reflective material conforms to Federal Specification L-S- 300 (September 7, 1965) and, as used on the vehicle, meets the performance standards of SAE Standard J594f Reflex Reflectors, Jan uary 1977. Accordingly, if your red and amber samples meet these two requirements, they may be used as the side front, intermediate, and rear reflex reflectors that Tables I and III require on trucks and trailers. However, Standard No. 108 does not all ow sheeting material to be used on the rear of vehicles in lieu of reflex reflectors.

What if your reflectors do not meet the two specifications listed above? In this instance, they may be used as supplementary side reflectors to the reflectors that are

2

required by Standard No. 108, and you may employ amber devices for this use as well as red and white. As supplementary equipment, they are subject to the Federal restriction only that they not impair the effectiveness of the required reflex reflectors. We do not believe that additional reflectors would have this effect. Supplementary lighting equipment such as additional reflectors is subject to the laws of the individual states. We are not able to advise you as to their acceptability under state la ws. The American Association of Motor Vehicle Administrators (AAMVA) provides opinions on state law. AAMVA's address is 4600 Wilson Blvd., Arlington, Va. 22203.

As you may know, S5.7 of Standard No. 108 requires red and white retroreflective material to be applied to the side and rear of large trailers that have been manufactured since November 30, 1993 (those whose overall width is 80 inches or more and whose G VWR is more than 10,000 pounds). This material may be retroreflective sheeting or reflectors. If sheeting is used, it must meet the photometric specifications of Figure 29. If reflectors are used, they must conform to SAE J594f, and provide specified minimum millicandela/lux at specified light entrance angles. Your initial question indicates that you may be interested in marketing Saf-T-Flec for use as a substitute for the conspicuity materials that conform to Standard No. 108. Manufacturers of con spicuity sheeting certify it with the material in a flat vertical plane (as evidenced by the DOT-C2 marking on your white sample). We have reservations whether the curved red and white Saf-T-Flec devices could meet the photometric specifications of Figu re 29, for sheeting, or J594f and the millicandela/lux specifications of S5.7.2.1(b) or (c) for reflectors. Amber is not one of the specified colors for conspicuity treatment, and could not be used as a substitute.

I hope that this answers your questions.

ATTACHMT: Attached to letter dated 6/6/94 from Hellfried Sandig to Richard van Iderstine

TEXT: This responds to your FAX of June 6, 1994, to Mr. Van Iderstine of this agency, asking for an interpretation of Motor Vehicle Safety Standard No. 108.

You present a drawing of a rear combination lamp incorporating one stop lamp and two taillamps. You have asked whether it is "necessary that we must have the ratio 5:1/3:1 between the stop and the tail lamp measurements in this arrangement?"

If the lamp is intended for use on narrower vehicles, the answer depends upon the distance between the optical axes of the stop and taillamp functions. SAE Standard J586 FEB84 Stop Lamps for Use on Motor Vehicles Less Than 2032 mm in Overall Width is in corporated by reference in Standard No. 108. Paragraph 5.1.5.3 of J586 is the source of the ratio: "[w]hen a tail lamp is combined with the stop lamp, the stop lamp shall not be less than three times the luminous intensity of the tail lamp at any test p oint; except that at H-V, H-5L, H-5R, and 5U-V, the stop lamp shall not be less than five times the luminous intensity of the tail lamp." However, in a multiple compartment lamp such as yours, if "the distance between optical axes for one of the function s exceeds the dimensions specified in paragraph 5.1.5.2 [i.e., 560 mm] the ratio shall be computed for only those compartments or lamps where the tail lamp and stop lamp are optically combined." Although your combination lamp design combines the two func tions, your drawing indicates that they are not optically combined, and the ratio will not apply if the optical axes are more than 560 mm apart. The ratio will apply if the distance between the optical axis of the stop lamp and that of either taillamp i s 560 mm or less.

SAE Standard J1398 MAY85 Stop Lamps for Use on Motor Vehicles 2032 mm or More in Overall Width is the standard incorporated in Standard No. 108 that applies to lamps used on wider

2

vehicles. Its paragraph 5.1.5.2 establishes the same 5:3 ratio (though not including H-5L in the five times ratio), but does not provide an exception based upon spacing of optical axes. Thus, if your lamp is designed for wider vehicles, the ratio appli es regardless of the spacing of the optical axes.

ATTACHMT: Attached to letter dated 5/24/94 from Carmen Colet to Dorothy Nakama (OCC-10060)

TEXT: This responds to your request for an interpretation whether Standard No. 115, Vehicle identification number - basic requirements or any other Federal Motor Vehicle Safety Standard (FMVSS) applies to your "aircraft rescue and fire-fighting vehicle." As ex plained below, the answer is no.

Your letter states that your company is constructing the vehicle "to satisfy proposed U.S.A.F. and D.O.D." specifications. The vehicle is made to operate on airfields. You described the unusual configuration of the vehicle as having a "cockpit" that is "similar to 117A Stealth Fighter," having bumpers that are 5 feet high, and having a "power water turret on top." You further stated that vehicle uses tires 54 inches high and over two feet wide, that are made to be run on only for 20 minutes, at a spee d of up to 65 miles per hour.

Enclosed with your letter is a picture of the vehicle, which you asked be kept confidential. Although your request for confidentiality does not comply with NHTSA's regulations at 49 CFR part 512 Confidential Business Information, in order to save time, I will not publicly disclose the picture.

The FMVSSs apply only to "motor vehicles," within the meaning of 49 U.S.C. @ 30102 (a)(6). "Motor vehicle" is defined at section 30102(a)(6) as:

a vehicle driven or drawn by mechanical power and manufactured primarily for use on public streets, roads, and highways, but does not include a vehicle operated only on a rail line.

We have interpreted this language to mean that vehicles designed and sold solely for off-road use are not considered motor vehicles, even though they may be operationally capable of highway travel. In an interpretation letter of

2

December 28, 1979, to Walter Motor Truck Company, NHTSA determined that the Walter airport crash-fire-rescue vehicle does not qualify as a motor vehicle subject to the FMVSS. Your description of your aircraft rescue vehicle indicates that the vehicle is to be used only within an airfield. In particular, the size and 20 minute running time of the tires, appears to make the vehicle impracticable for highway use.

Based on the information you have provided, and our understanding that your vehicles are neither used on public roads nor suitable for such use, we conclude that the "aircraft rescue and fire-fighting vehicle" is not a "motor vehicle" within the meaning of the National Traffic and Motor Vehicle Safety Act. Thus, your vehicle is not subject to Standard No. 115. Since you are not a manufacturer of a "motor vehicle," you do not have to furnish NHTSA with information pursuant to 49 CFR part 566 Manufactur er Identification.

Enclosed with this letter is your picture of the aircraft rescue and fire-fighting vehicle. If you have any questions, please contact Dorothy Nakama of my staff at (202) 366-2992.

ATTACHMT: Attached to letter dated 09/02/94 from John Womack to Paul Frink (A42; STD. 206)

TEXT: Avionic Structures, Inc. is in the process of manufacturing a door/door frame system that is specifically intended to be installed in a vehicle classified as a Recreational Motor Home.

The door/door frame system is located on the passenger side of the vehicle and directly across from the drivers seat. The location and use of this door is as the primary egress for the vehicle.

The passenger seat is in close proximity to this door, however, as shown on the diagram enclosed the passenger seat is behind the step area extending from the door opening into the coach.

The door/door frame assembly, as manufactured by Avionic Structures is installed into the side wall of the vehicle (motor home) and bolted into place by the vehicle manufacturer. The door/door frame assembly is thus a component part of the sidewall. Se e Dwg. 1.

The door hinging is located between the forward vertical post of the door and the forward vertical member of the frame. The locking and latching components are opposite the hinges on the trailing post of the door and frame. See Dwg. 2.

The double rotor latch and striker bolt are components purchased from Tri-Mark Corporation. These components have been subjected to the test requirements of SAEJ839-JUL92 static load testing. The report submitted by Tri-Mark Corporation to Avionic Stru ctures indicates their units met or exceeded these requirements. See enclosed data sheet from Tri-Mark.

Since the door we have described to you is the only egress for occupants and belongings, as generally used in the living quarters of a Motor Home, Avionic Structures feels it is important for us to understand what category (for testing requirements) this installation falls under.

We would appreciate a clarification as to the need for this door/door frame system to conform to a specific portion of DOT Standard No. 206.

Thank you in advance for your help and prompty reply.

TITLE: Request for Interpretation relating to 49 CFR Parts 541 and 543, Theft Prevention Standard (Parts Marking Requirements for Replacement Parts)

ATTACHMT: ATTACHED TO 2/17/95 LETTER FROM PHILIP R. RECHT TO DIETMAR K. HAENCHEN (A43; PART 543; PART 541)

TEXT: Thank you for your quick response to our request for interpretation dated 17 May 1994 relating to the marking requirements for replacement parts. This letter presents a follow-up question to the interpretation you gave us relative to the Volkswagen Corr ado carline.

Your interpretation concluded that because the Corrado will not be offered for sale in the United States as a 1995 model year carline (the model year for which the exemption from parts marking on the basis of an approved anti-theft device was granted), t he replacement parts for the 1994 model year and prior years would continue to have to be marked. This was because "no Corrados sold in the U.S. will be equipped with the approved anti-theft device".

However, the fact is that all 1994 model year Corrados were sold in the U.S. with the standard anti-theft device that was approved for the 1995 model year exemption. (The 1994 model year Corrado was parts marked in addition to being equipped with a stan dard anti-theft device.)

Volkswagen could not apply for an anti-theft system exemption for the 1994 model year Corrado because only two exemptions are allowed per model year. For 1994, Volkswagen chose to exempt the Jetta III and the Volkswagen Cabrio carlines.

Volkswagen believes that marking of replacement parts for the Corrado carline can be terminated because the 1994 model year Corrado carline was equipped with a standard anti-theft device that was approved for exemption so that the requirement that Corrad o vehicles be sold in the United States with the approved anti-theft device was, in fact, met. Your interpretation on this issue is requested.

Thank you for your consideration and we look forward to your early response.

ATTACHMT: Attached to a letter dated 6/1/94 from Donald W. Vierimaa to John Womack

TEXT: This responds to your letter of June 1, 1994, requesting an interpretation of Motor Vehicle Safety Standard No. 108.

You have asked whether the term "underride protection device" as used in S5.7.1.4.1 in Standard No. 108 "only include the device yet to be required by NHTSA or would it include the device described in TTMA RP No. 92?"

At present, the term "rear underride protection device" as used in Standard No. 108 means the common "ICC bumper" described by the Federal Highway Administration in 49 CFR 393.86, or a similar device that the manufacturer of a trailer has provided regard less of whether it is required by 49 CFR 393.86. Thus, it presently includes the device described in TTMA RP No. 92.

You have informed us that some manufacturers are installing guards with round cross sections, and some with square cross sections rotated 45 degrees which results in a "diamond" shape orientation. In addition, on some trash trailers, a curved hook grabs and holds the round cross section guard while trash is loaded into the trailers. You have asked whether a 38 mm wide retroreflective strip of sheeting applied to these guards will comply with Standard No. 108.

S5.7.1.4.1(c) of Standard No. 108 specifies only that the strip shall be applied "across the full width of the horizontal member of the rear underride protection device." Although the reflective material is certified by its manufacturer for photometric c onformance in the vertical position, Standard No. 108 has not been interpreted to require structural changes in trailers for the sole purpose of enhancing the conspicuity installation. The agency's decision to avoid exceptions for trailers with unusual configurations was based on the expectation that manufacturers would use

2

their available structures for conspicuity material, rather than re-engineer them. Thus, we believe that the application of 38 mm wide sheeting to either of these guards would comply with S5.7.1.4.1(c).
