Pavement Markings
Double White Line
Two solid white lines between lanes mean lane changes are prohibited — stay in your lane.
What This Sign Means
Double white lines separate same-direction lanes where changing lanes is dangerous, such as approaching intersections, tunnels, or dedicated lanes.
What You Should Do
Stay in your lane until the double line ends or becomes broken.
Knowledge Test Tip
White line logic: solid white = stay in lane, broken white = lane changes permitted, double solid white = never cross.
