What does a single broken white line in the center of a two-lane road mean?
A single broken white line signifies that the lanes on either side are traveling in the same direction. Drivers next to this line are allowed to change lanes by crossing it if it is safe to do so. This marking encourages organized and flexible lane use, permitting vehicles to overtake if conditions permit while still aligning with overall traffic flow. Ensuring it's safe to pass before doing so is essential to avoid collisions and maintain order on the road.
