What does a dashed yellow line indicate?

A dashed yellow line indicates that passing is allowed, but it must be done with caution. This marking is used on roadways to provide drivers with the flexibility to overtake slower vehicles when it is safe to do so. It serves as a visual cue that the lane is designated for both directions of traffic, meaning vehicles can safely cross the line to pass another vehicle.

This situation contrasts with other line markings, such as solid yellow lines, which indicate that passing is not permitted due to safety risks, usually in areas where visibility is limited or where there are curves. A dashed yellow line communicates that while passing is permissible, drivers should ensure the road is clear and that it is safe before executing the maneuver.
