What is true about a broken white line?

A broken white line serves as a guideline for drivers regarding lane management on roads where traffic flows in the same direction. The key point about a broken white line is that it indicates that drivers are permitted to change lanes or overtake another vehicle when it is safe to do so. This feature allows for flexibility in driving behavior, promoting safe overtaking under appropriate conditions.

While the other options address various aspects of road markings, they do not accurately reflect the function of a broken white line. For instance, a solid line would indicate a no-overtaking zone, and pedestrian crossings typically utilize different markings, such as solid lines or other distinctive patterns to alert drivers. Thus, the option confirming the permissibility of overtaking at a broken white line highlights its role in encouraging safe driving practices, making it the correct choice in this context.
