A yellow dashed line indicates which type of roadway?

A yellow dashed line on a roadway indicates that it is a two-way road. This marking allows traffic in opposite directions to pass each other safely, signaling that vehicles may cross the line to overtake slower-moving vehicles when it is safe to do so. The presence of the dashed line is crucial for maintaining flow and safety on roads where lanes run in two directions.

In contrast, other markings like solid yellow lines designate a no-passing zone, while one-way roads would typically use solid white lines or specific signage to indicate the intended traffic flow. A dashed line may also suggest that a passing maneuver is permissible if conditions allow, which is not consistent with the characteristics of pedestrian pathways or one-way streets. Therefore, the yellow dashed line effectively communicates the two-way nature of the roadway and the rules associated with passing.
