What does a dashed yellow line indicate?

A dashed yellow line indicates that passing is allowed when it is safe to do so. This marking is commonly found on two-lane roads where traffic moves in opposite directions. The dashed line signals that a driver may switch lanes to overtake another vehicle, provided that they can do so without endangering themselves or other road users.

In contrast, a solid yellow line would indicate that passing is not permitted, providing a different context for drivers. Also, lane changes may be restricted by other markings or signs, and pedestrian crossings are identified by specific road signs or markings separate from lane lines. Therefore, the presence of a dashed yellow line clearly communicates to drivers that they can legally pass another vehicle if conditions allow.
