or where the location of the tracks prevents compliance with this section, with

regard for other traffic.

(2) (a) The driver of a vehicle overtaking a bicycle or electric low -speed scooter

proceeding in the same direction shall:

1. If there is more than one (1) lane for traffic proceeding in the same

direction, move the vehicle to the immediate left, if the lane is available

then the driver of the passing vehicle shall use reasonab le caution in

passing the bicyclist or electric low-speed scooter operator.

(b) The driver of a motor vehicle may drive to the left of the center of a roadway,

including when a no -passing zone is marked in accordance with subsection

(6) of this section, to pass a person operating a bicycle or electric low -speed

scooter only if the roadway to the left of the center is unobstructed for a

sufficient distance to permit the driver to pass the person operating the bicycle

or electric low -speed scooter safely and avoid interference with oncoming

traffic. This paragraph does not authorize driving on the left side of the center

of the roadway when otherwise prohibited under state law.

(c) The operator of a bicycle or electric low -speed scooter shall not ride more

or more lines of vehicles moving lawfully in the direction being traveled by

the overtaking vehicle.

under conditions permitting the passing in safety, and not by driving off the

roadway unless the vehicle being passed is at a complete stop and the passing may

be made safely.

(5) A person shall not drive a vehicle 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 inter fering

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.

(6) 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 approp riate signs or markings on the

roadway indicate the beginning and end of the zones, and when signs or markings

are in place and clearly visible to an ordinarily observant person, every driver of a

vehicle shall obey the directions thereof, except as provid ed for in subsection (2)(b)

of this section.

(7) Whenever any roadway has been divided into three (3) or more clearly marked

lanes for travel in one (1) direction, the following additional rules shall apply:

single lane and shall not move from that lane until the driver ascertains that

the movement can be made with safety;

(b) A person shall not drive a vehicle in the center lane except when overtaking

and passing another veh icle where the roadway is clearly visible and the

center lane is clear of traffic within a safe distance, or in preparation for a left

moving in the direction in which the vehicle is proceeding and is signposted

to give notice of the allocation;

(c) A person shall not operate a truck tractor, trailer, or semitrailer in the leftmost

lane except when entering or leaving a highway, yielding to traffic coming

onto the highway, or when t raffic conditions exist which would prohibit safe

use of the right or center lanes; and

(d) 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 these signs.

(8) On any limited access highway of four (4) lanes or more with a posted speed limit

of at least sixty-five (65) miles per hour, a person shall not operate a motor vehicle

in the leftmost lane, except when:

(a) Overtaking a slower vehicle;

(b) Yielding to traffic coming onto the highway; or

(c) Traffic or road conditions exist which would prohibit safe use of the right or

center lanes.

(9) (a) Except as provided in paragraph (c) of this subsection, the operator of a motor

condition of the highway.

motor truck, semitrailer truck, bus, or heavy construction equipment unit,

when traveling upon a highway outside of a business or residential district,
