TEXT:
This responds to your letter and telephone call to this office asking our opinion regarding Federal Motor Vehicle Safety Standard (FMVSS) No. 120, Tire selection and rims for motor vehicles other than passenger cars. Your letter referenced a telephone c onversation with Walter Myers of my staff about the applicability of FMVSS 120 to your product. As Mr. Myers informed you, the answer to your question depends on whether your product, the "Wishbone Carriage" used to position and carry the "Priefert live stock chute" is a "motor vehicle" (i.e., trailer) under our Safety Act and regulations. Based on the information we have, we believe the answer is no.
By way of background information, the National Traffic and Motor Vehicle Safety Act of 1966, 15 U.S.C. S1381, et seq. (Safety Act), authorizes this agency, the National Highway Traffic Safety Administration (NHTSA), to issue safety standards applicable t o motor vehicles. Section 102(3) (15 U.S.C. S1391(3)) of the Safety Act defines motor vehicle as:
(A)ny 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 further defines "trailer" in 49 CFR 571.3 as:
(A) motor vehicle with or without motive power, designed for carrying persons or property and for being drawn by another motor vehicle.
Your letter enclosed a brochure containing pictures and other information relating to the livestock chute (Priefert Squeeze Chute, Model 91). The chute is farm equipment. The upper 2/3 of the chute is constructed of steel bars, while the lower 1/3 is c omposed of steel panels on both sides that can be lowered or removed. The chute comes with such accessories as head gate, tail gate, and calf table. The chute is positioned on the ground in a barnyard, feed lot, pasture, or field. It is used to channe l livestock or, with the head and/or tail gate in place, to immobilize an animal for medicating, branding, tagging, and the like. Your information also describes the carriage that transports the chute. The Wishbone Carriage is a 2-wheeled U-shaped doll y which is designed to be manually attached to special fittings on the chute.
With the carriage thus attached, the chute can be towed by vehicle to the next job site. Once at the next job site, the wheeled carriage is detached and the chute is once again placed on the ground for use.
Whether the Wishbone Carriage is a motor vehicle (trailer) depends on its on-road use. This agency has consistently held that vehicles designed and sold solely for off-road use, such as airport runway vehicles and underground mining equipment, are not c onsidered 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 that have a maximum speed of 20 miles per hour ar e not considered motor vehicles. Agricultural equipment, such as tractors, as well as equipment that uses the highways solely to move between job sites and which typically spend extended periods of time at a single job site, are not considered motor veh icles. That is because the use of these vehicles on the public roadways is intermittent and merely incidental to their primary off-road use.
We have determined that the Wishbone Carriage is not a motor vehicle, because it appears it will be primarily used to transport the chute from job site to job site on the farm. Not being a motor vehicle, the Federal motor vehicle safety standards, inclu ding FMVSS No. 120, would not apply to your product.
Please note, however, that if the Carriage is regularly used to carry the chute from farm to farm on public roads, or is used more frequently on the public roads than the use we anticipate, the agency may reexamine the determination that the carriage is not a motor vehicle. Also, you may wish to consult your attorney for information on possible operational restrictions on your product, such as State licensing and use laws and product liability.
I hope this information is helpful to you. We have enclosed a copy of FMVSS 120 and provided you our definition of a trailer, as you requested. Should you have any further questions or need additional information, please feel free to contact Mr. Myers at this address or at (202) 366-2992.
