You drive in the right lane of a four-lane divided highway. A broken white line separates your lane from the lane on your left. What does this line tell you?
A travels in the right northbound lane of a four-lane highway. A grass median divides the opposing roadways; a broken white line separates the two northbound lanes.
Correct answer: Traffic in the left lane goes your way, and you may move into it when it is safe.
Why
Line color tells you the direction of traffic: white lines separate lanes that go the same way, and yellow lines separate opposing traffic. A broken white line lets you change lanes, but state law also requires you to stay within one lane until you are sure that a move is safe. Before you cross the line, check your mirrors and your blind spot, and signal.
