Any vehicle proceeding upon a road at a speed less than the normal speed of traffic moving in the same direction at such time shall be driven in the right-hand lane for traffic or as close as practicable to the right-hand edge or curb, except when overtaking and passing another vehicle proceeding in the same direction or when preparing for a left turn at an intersection or into a private road or driveway.
On a two-lane road where passing is unsafe because of traffic in the opposite direction or other conditions, any vehicle proceeding upon the highway at a speed less than the normal speed of traffic moving in the same direction at that time, behind which five or more vehicles are formed in line, shall turn off the roadway at the nearest place where sufficient area for a safe turnout exists, in order to permit the vehicles following it to proceed.
Whenever any roadway has been divided into two or more clearly marked lanes for traffic in one direction, the following rules apply
A vehicle shall be driven as nearly as practical entirely within a single lane and shall not be moved from the lane until such movement can be made with reasonable safety.
Exception: Driving a motorcycle that has only two wheels in contact with the ground, between rows of stopped or moving vehicles in the same lane, including on both divided and undivided streets, roads, or highways is permitted.
On a two-lane highway, 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 such overtaking and passing to be completely made without interfering with the safe operation of any vehicle approaching from the opposite direction.
