189.340 Overtaking vehicles -- Traffic lanes -- Following vehicles.
Vehicles overtaking other vehicles proceeding in the same direction shall pass to the
left of them and shall not again drive to the right until reasonably clear of those
vehicles. Vehicles overtaking streetcars may pass either to the right or left when so
directed by a police officer, when on a one (1) way street or where the location of
the tracks prevents compliance with this section, with regard for other traffic.
The operator of a vehicle may overtake and pass upon the right of another vehicle
only under the following conditions:
(a) When the vehicle overtaken is making or about to make a left turn;
(b) Upon a roadway with unobstructed pavement of sufficient width for two (2) or
more lines of vehicles moving lawfully in the direction being traveled by the
The operator of a vehicle may overtake and pass another vehicle upon the right only
under conditions permitting such movements in safety. Such movement shall not be
made by driving off the roadway unless passing vehicle comes to a complete stop
and such movement may be made safely.
No vehicle shall be driven to the left side of the center of the roadway in overtaking
and passing another vehicle proceeding in the same direction unless the left side is
clearly visible and free of oncoming traffic for a sufficient distance ahead to permit
overtaking and passing to be completely made without interfering with the safe
operation of any vehicle approaching from the opposite direction or any vehicle
overtaken. In every event, the overtaking vehicle must return to the right-hand side
of the roadway before coming within two hundred (200) feet of any vehicle
approaching from the opposite direction.
The commissioner of highways is hereby authorized to determine those portions of
any highway where overtaking and passing or driving to the left of the roadway
would be especially hazardous and may by appropriate signs or markings on the
roadway indicate the beginning and end of such zones, and when such signs or
markings are in place and clearly visible to an ordinarily observant person, every
driver of a vehicle shall obey the directions thereof.
Whenever any roadway has been divided into three (3) clearly marked lanes for
travel, the following additional rules shall apply:
(a) A vehicle shall be driven as nearly as may be practical entirely within a single
lane and shall not be moved from that lane until the driver has first ascertained
that the movement can be made with safety;
(b) A vehicle shall not be driven in the center lane except when overtaking and
passing another vehicle where the roadway is clearly visible and the center
lane is clear of traffic within a safe distance, or in preparation for a left turn or
where a center lane is at the time allocated exclusively to traffic moving in the
direction in which the vehicle is proceeding and is signposted to give notice of
the allocation; and
(c) Official signs may be erected directing slow-moving traffic to use a
designated lane or allocating specified lanes to traffic moving in the same
direction and operators of vehicles shall obey the directions of such signs.
A vehicle shall not be driven in the left lane of any limited access highway of four
(4) lanes or more with a posted speed limit of at least sixty-five (65) miles per hour,
except in overtaking a slower vehicle, yielding to traffic coming onto such a
highway, or when traffic conditions exist which would prohibit safe use of the right
or center lanes.
(a) The operator of a motor vehicle shall not follow another vehicle more closely
than is reasonable and prudent, having regard for the speed of the vehicle and
the traffic upon and condition of the highway.
(b) The operator of any motor truck, semitrailer truck, bus, or heavy construction
equipment unit, when traveling upon a highway outside of a business or
residential district, shall not follow within two hundred fifty (250) feet of
another such vehicle or equipment unit. This subsection shall not prevent
overtaking and passing, nor shall it apply to any lane specially designated for
use of motor trucks or semitrailer trucks, buses or heavy construction
