What does a broken white line signify on the road?

A broken white line on the road signifies that overtaking is permissible, provided it can be done safely. This line indicates that the lanes are separate but does not prohibit crossing to pass another vehicle when conditions allow for it. Drivers are expected to assess their surroundings, including the speed of oncoming traffic and visibility, before making the decision to overtake.

The other options describe situations that do not align with the meaning of a broken white line. For instance, a solid line would indicate restrictions such as no overtaking, and a stop line would be related to intersections or pedestrian crossings where a vehicle must yield. Understanding the function of road markings like the broken white line is crucial for safe driving and adherence to road rules.
