What does a dashed white line separating lanes indicate?

• A. You may pass if it is safe to do so and if not restricted by other signs or lines.
• B. Lane changes are prohibited.
• C. You must stay in your lane and not cross the line.
• D. It marks the edge of the roadway.

Answer: (A)

Dashed white lines between lanes show that traffic is moving in the same direction and you may change lanes or pass other vehicles when it’s safe, as long as nothing else signs or lines restrict it. This marking gives you the option to move to an adjacent lane to pass a slower vehicle or prepare for an upcoming exit, but you must signal, check mirrors and blind spots, and ensure there’s enough space before crossing. The restriction to not cross would come from a solid line instead, or other signs. The edge of the roadway is marked by a solid line along the outside, not by the dashed line between lanes.
