When is it improper to cross a single broken white or yellow line?
Correct answer: A – When the movement cannot be completed safely without interfering with traffic
A broken line may permit a lane change or, when yellow, a pass across the centerline. The driver must first determine that the movement can be completed safely and without interfering with another vehicle. Traffic, visibility, signs, and other passing restrictions may still prohibit the maneuver.
