61-8-328. Driving on roadways laned for traffic. Whenever a roadway has been divided into two or more clearly marked lanes for traffic, the following rules, in addition to all other consistent rules, apply:
     (1) A vehicle must be driven as nearly as practicable entirely within a single lane and may not be moved from the lane until the driver has first ascertained that the movement can be made with safety.
     (2) Upon a roadway that is divided into three lanes, a vehicle may not be driven in the center lane except:
     (a) when overtaking and passing another vehicle where the roadway is clearly visible and the center lane is clear of traffic within a safe distance;
     (b) in preparation for a left turn; or
     (c) when the center lane is at the time allocated exclusively to traffic moving in the direction that the vehicle is proceeding and is signposted 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. Drivers of vehicles shall obey the directions of every official sign that designates use of specific lanes.
     (4) A person may turn a vehicle left across a lane marked with two yellow lines into a public or private parking lot or a roadway if the turn can be made safely and if the person does not hinder the flow of oncoming traffic.
