Driving on Roadway Laned for Traffic
An operator on a roadway divided into two or more clearly marked lanes for traffic:
shall drive as nearly as practical entirely within a single lane; and
may not move from the lane unless that movement can be made safely.
If a roadway is divided into three lanes and provides for two-way movement of traffic, an operator on the roadway may not drive in the center lane except:
if passing another vehicle and the center lane is clear of traffic within a safe distance;
in preparing to make a left turn; or
where the center lane is designated by an official traffic-control device for movement in the direction in which the operator is moving.
Without regard to the center of the roadway, an official traffic-control device may be erected directing slow-moving traffic to use a designated lane or designating lanes to be used by traffic moving in a particular direction.
Official traffic-control devices prohibiting the changing of lanes on sections of roadway may be installed.Acts 1995, 74th Leg., ch. 165, Sec. 1, eff. Sept. 1, 1995.
