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.
