What does a broken yellow line signify?

A broken yellow line signifies that passing on the left is permitted when it is safe to do so. This indicates a separation between lanes of traffic moving in opposite directions, and the broken line suggests that drivers are allowed to overtake another vehicle, provided that the maneuver can be completed safely and without endangering other road users.

This marking is often used on roads where there is a frequent need for passing but also recognizes the risks involved. In contrast, solid lines (either yellow or white) typically indicate restrictions on such maneuvers. The presence of a broken yellow line clearly communicates to drivers that they have the option to pass when conditions are favorable, thereby facilitating smoother traffic flow while maintaining safety.
