Turns, Lanes, Passing & MergingStandalone practice
Two lanes moving in the same direction are separated by double solid white lines. What must you do?
Blue A travels east in a same-direction lane beside two solid white lines. A broken-white opening lies farther ahead.
Correct answer: Stay in your lane and do not cross the lines.
Why
Do not change lanes across double solid white lines. A single solid white line discourages a lane change; a broken white line permits one when safe. Obey applicable official directions and plan lane changes before a restricted section.
