What does a broken white line indicate?

A broken white line indicates that lane changes are permitted. This means that drivers can safely change lanes when necessary, as long as it is safe to do so and does not interfere with the traffic. The broken line serves as a guide to denote that other vehicles may also be using the adjacent lane, and it is essential for drivers to check their mirrors and ensure there is enough space before making a lane change.

In contrast, a solid white line would indicate that lane changes are not allowed, while a broken line’s presence explicitly permits such actions. Knowing the significance of lane markings is crucial for safe driving, as it helps maintain proper vehicle flow and enhances safety on the road. Road closure signs would indicate a different scenario entirely, unrelated to lane markings.
