(1) 
A vehicle shall be driven as nearly as practicable entirely within a single lane and shall not be moved from the lane until the driver has first ascertained that the movement can be made with safety and then given a signal, not less than the last 100 feet traveled by the vehicle, of his intention to change lanes.
(2) 
Upon a roadway which is divided into three lanes, a vehicle shall not be driven in the center lane except when overtaking and passing another vehicle where the roadway is clearly visible and such center lane is clear of traffic within a safe distance, or in preparation for a left turn or where such center lane is at the time allocated exclusively to traffic moving in the direction the vehicle is proceeding and is signposted to give notice of such allocation.
(3)
