TITLE: FMVSR INTERPRETATION

TEXT: In your letter of April 20, 1971, to Robert L. Carter you ask for copies of regulations governing "the construction, equipping, and operation of private motor coaches." It is our understanding that you wish to construct a vehicle for your own use upon a standard Dodge M-300 motor coach chassis.

A motor coach is categorized as a "multipurpose passenger vehicle" under the Federal motor vehicle safety standards. I enclose copies of the following safety standards which would apply to the motor coach body that you wish to construct, and with which you, as a "manufacturer" of a motor vehicle, must ensure compliance.

102 - Transmission Shift Lever, etc. (Note S3.2)

103 - Windshield Defrosting and Defogging Systems

104 - Windshield Wiping and Washing Systems

107 - Reflecting Surfaces

108 - Lamps, Reflective Devices, and Associate Equipment

111 - Rearview Mirrors

205 - Glazing Materials

206 - Door Locks and Door Retention Components

208 - Seat Belt Installation (effective July 1, 1971)

209 - Seat Belt Assemblies (effective September 1, 1971; the requirements in effect until then apply only to equipment manufacturers)

This agency has no regulations governing the "operation" of a private motor home; however, Michigan may have special provisions as a prerequisite to the registration of a motor home.

Sincerely,

Enclosures

Re: Construction and Equipment Requirements Motor Coaches - Recreational Vehicles.

Would you kindly send me the regulations which govern the construction, equipping and operation of private motor coaches? I am proposing to construct such a coach for my own use, starting with a standard Dodge M-300 motor coach chassis designed for the purpose, and presumably meeting all current regulations which apply to the chassis and drive-train, etc. My concern thereafter, is with the requirements governing the body dimensions, clearance lighting, etc.

Your prompt attention will be appreciated.
