Traffic Signals & Road MarkingsStandalone practice
Two solid white lines separate same-direction travel lanes. What do they tell you about changing lanes across them?
Blue A travels east in a same-direction lane beside two solid white lines. A broken-white opening lies farther ahead.
Correct answer: Do not cross them to change lanes.
Why
Double solid white lines separate traffic moving in the same direction and prohibit crossing. Stay in your lane and use a later location where a lane change is permitted and safe. Signaling alone does not authorize crossing the lines.
