A broken white line indicates that lane changes are allowed. This marking is used to separate lanes of traffic moving in the same direction. Drivers may change lanes when it is safe to do so, meaning they should ensure there are no vehicles in their blind spot and that their turn signals are utilized. The broken line serves as a guide that lane changes can occur, promoting fluidity in traffic while maintaining safety.

The other choices reflect rules for different road markings. A solid white line, for instance, indicates that lane changes should be avoided, while specific markings for parking or no-entry zones have entirely different contexts related to either stopping or restricted access. Understanding these distinctions is vital for safe navigation on the roads.
