Title 47. Motor Vehicles
§47-11-406. Farm tractors or implements - Operation on highways - Permission from Department required - Wide vehicles - Duty of operator - Yield of right-of-way.

A. A farm tractor, as defined in Section 1-118 of this title, or any implement of husbandry, as defined in Section 1-125 of this title, except trailers and semitrailers when operated in accordance with statutory limits or provisions of Section 14-101 of this title, shall not be permitted to travel upon any highway in this state which is a part of the National System of Interstate and Defense Highways. However, the Department of Public Safety shall have the authority to permit such travel in certain geographic areas of the state as deemed necessary. Such tractor or implement may be operated on any other roadway in this state if the operator has attached all the safety devices required by law and has taken reasonable steps to reduce the width of the tractor or implement as provided for by the manufacturer. Whenever the width of a farm tractor or implement of husbandry exceeds the width of that portion of a roadway on which the tractor or implement is driven, which is marked as a single lane of traffic, or, if the roadway has not been marked for lanes of traffic and the width of the tractor or implement exceeds more than fifty percent (50%) of the width of the roadway, the operator shall move the tractor or implement, as soon as possible, as far to the right-hand side of the roadway as is practicable and safe upon approach of any oncoming or following vehicle and upon approaching the crest of a hill.

B. Upon the immediate approach of a farm tractor or implement of husbandry which cannot be moved by the operator thereof to the far right-hand side of the roadway, as required in subsection A of this section, due to the existence of any bridge or guardrail, sign or any other physical impediment which would not safely allow such tractor or implement to travel on the far right-hand side of the road, the driver of every other vehicle shall yield the right-of-way and shall immediately pull over to the far right-hand side of the road and remain in such position until the tractor or implement has passed.

C. This section shall not operate to relieve any operator of a farm tractor or implement of husbandry from the duty to drive with due regard for the safety of all persons using the roadway.
