AAA Driver's Ed Permit Practice Test

Solid double white lines indicate you must stay in your lane and not change lanes or pass. They’re placed where moving between lanes would be unsafe, so the safest and correct action is to remain in your lane until you reach a point where the lines end or crossing is permitted. That’s why the statement about lane changes being allowed isn’t correct, and passing across these lines isn’t permitted even if traffic appears to be moving slowly. The idea that it marks the edge of the road isn’t accurate either—edge markings are a different type of line.
