   (1) A vehicle shall be driven as nearly as practical 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.

   (2) Upon a roadway which is divided into three (3) 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 the center lane is clear of traffic within a safe distance, or in preparation for a left turn or where the center lane is at the time allocated exclusively to traffic moving in the direction the vehicle is proceeding and is sign-posted to give notice of the allocation.

   (3) Official signs may be erected directing slow-moving traffic to use a designated lane or designating those lanes to be used by traffic moving in a particular direction regardless of the center of the roadway, and drivers of vehicles shall obey the directions of the sign.

   (4) Violations of this section are subject to fines enumerated in § 31-41.1-4.
