(A) 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. The person operating or in charge of the overtaking vehicle shall sound his horn or other sound device before passing. Vehicles overtaking street cars may pass either to the right or left when so directed by a police officer, when on a one-way street or where the location of the tracks prevents compliance with this section, with regard for other traffic. (KRS 189.340(1))
(B) (1) Vehicles overtaking a bicycle or electric low-speed scooter proceeding in the same direction shall:
(a) If there is more than one lane for traffic proceeding in the same direction, move the vehicle to the immediate left, if the lane is available and moving in the lane is reasonably safe; or
(b) If there is only one lane for traffic proceeding in the same direction, pass to the left of the bicycle or electric low-speed scooter at a distance of not less than three feet between any portion of the vehicle and the bicycle or electric low-speed scooter and maintain that distance until safely past the overtaken bicycle or electric low-speed scooter. If space on the roadway is not available to have a minimum distance of three feet between the vehicle and the bicycle or electric low-speed scooter, then the driver of the passing vehicle shall use reasonable caution in passing the bicyclist or electric low-speed scooter operator.
(2) 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 § 71.11, 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.
(3) The operator of a bicycle or electric low-speed scooter shall not ride more than two abreast on a single highway lane unless operating on any part of the roadway marked exclusively for bicycle use. Persons riding two abreast shall not impede the normal and reasonable movement of traffic.
(C) The operator of a vehicle may overtake and pass upon the right of another vehicle only under the following conditions:
(1) When the vehicle overtaken is making or about to make a left turn;
(2) Upon a roadway with unobstructed pavement of sufficient width for 2 or more lines of vehicles moving lawfully in the direction being traveled by the overtaking vehicle. (KRS 189.340(3))
(D) 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. (KRS 189.340(4))
(E) The operator of a vehicle may overtake, and, allowing sufficient clearance, pass another vehicle proceeding in the same direction upon the left or upon the right on a roadway with unobstructed pavement of sufficient width for 4 or more lines of traffic when the movement can be made in safety. No person shall drive off the pavement or upon the shoulder of the roadway in overtaking or passing on the right.
(F) 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 200 feet of any vehicle approaching from the opposite direction.
