What does a broken white line mean?

Answer: B — You may change lanes if it is safe to do so

A broken white line on the road indicates that drivers are permitted to change lanes if it is safe to do so. This kind of line is used to separate lanes of traffic moving in the same direction. When you see a broken white line, it means that you have the option to change lanes, but you must ensure that it is safe — checking mirrors and blind spots — before making the maneuver. In contrast to a solid line, which would indicate that lane changing is not allowed, a broken line provides flexibility for drivers to navigate their vehicles as necessary based on the traffic conditions. This understanding is essential for safe driving and proper lane management on the road.
