TITLE: FMVSS INTERPRETATION

TEXT: This is in response to your September 8, 1976, letter requesting information concerning the Federal regulations that would be applicable to safety glazing for use in "slow moving" vehicles. Please excuse our delay in answering your questions. Apparently, your earlier letter of February 5, 1976, was misplaced.

Standard No. 205, Glazing Materials, specifies requirements for glazing materials for use in most motor vehicles and motor vehicle equipment. A glazing manufacturer must certify any glazing that is to be used in a motor vehicle (other than a trailer) as being in compliance with Standard No. 205. "Motor vehicle" is defined in @ 102(3) of the National Traffic and Motor Vehicle Safety Act of 1966. I am enclosing a copy of the agency's opinion of what vehicles qualify as "motor vehicles" under the definition. Glazing material that is to be used in a vehicle that does not qualify as a "motor vehicle" does not have to meet the performance requirements of Standard No. 205.

Sincerely,

Enclosure

Dear Mr. Carter,

On 5th February 1976 I wrote to the Department of Transportation requesting information on possible regulations in the U.S.A. governing the safety glazing to be fitted in slow moving vehicles. To date I have not received a reply. It may be that the letter was lost in the post and I, therefore, enclose a copy.

I realise, of course, that this query is probably nothing to do with your department, but I would be grateful if you could either forward it to the correct authority or alternatively let us have the address of this authority in order that we can write to them ourselves.

Yours sincerely,

MISS VALERIE HOOD -- Standards Department

The Administrator -- National Highway Traffic Safety Administration, U.S. Department of Transportation,

Dear Sir,

SLOW MOVING VEHICLES

Can you please let us know what regulations, if any, govern the type of safety glazing which must be fitted in slow moving vehicles (i.e. vehicles with a maximum speed of 20-25 km/h) in the U.S.A. These vehicles are usually agricultural or forestry vehicles, etc. which might go on a public road for short periods.

Our understanding of U.S. National Traffic and Motor Vehicle Safety Act 1966 and F.M.V.S.S. 205 are that neither covers such vehicles. The former describes a motor vehicle as "any vehicle driven or drawn by mechanical power manufactured primarily for use on public streets, roads and highways" and the latter applies only to passenger cars, multi-purpose passenger vehicles, trucks, buses, motor cycles, slide-in campers and pick up covers.

If the above query does not come within your jurisdiction, we would be grateful if you would forward our letter to the correct authority.

Yours faithfully, TRIPLEX SAFETY GLASS COMPANY LIMITED;

MISS VALERIE HOOD -- Standards Department
