What does a double yellow line indicate?

A double yellow line indicates that parking is not permitted at any time. This system of markings is designed to maintain the flow of traffic and ensure safety on the roads. In areas marked with double yellow lines, vehicles must not stop or park, giving priority to the smooth movement of other vehicles and reducing the risk of accidents. These lines are particularly common in locations where stopping could create hazards, such as near intersections, in front of driveways, or on busy roads.

The other options suggest various conditions under which parking might be allowed. However, the primary purpose of a double yellow line is to provide clear and unequivocal guidance that no parking is allowed at any time, enhancing road safety and accessibility.
