Kentucky Revised Statutes Title XVI. Motor Vehicles § 189.340.Overtaking vehicles, bicycles, or electric low-speed scooters; traffic lanes; following vehicles; exemption for commercial motor vehicle platoon trailing vehicle

(2)(a) The driver of a vehicle overtaking a bicycle or electric low-speed scooter proceeding in the same direction shall:

(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 than two (2) abreast on a single highway lane unless operating on any part of the roadway marked exclusively for bicycle use. Persons riding two (2) abreast shall not impede the normal and reasonable movement of traffic.

(a) When the vehicle overtaken is making or about to make a left turn; or

(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 overtaking vehicle.

(a) A person shall drive a vehicle as nearly as may be practical entirely within a 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 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;

(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 traffic 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.

(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 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) Except as provided in paragraph (c) of this subsection, 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 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 equipment units.

(c) Paragraphs (a) and (b) of this subsection shall not apply to a trailing commercial motor vehicle involved in a platoon as defined in KRS 281.010, but shall apply to the commercial motor vehicle leading a platoon.
