What does a solid yellow line indicate?

A solid yellow line is a critical road marking that indicates passing is not allowed. This means that if you see a solid yellow line on your side of the road, you must remain in your lane and should not attempt to overtake another vehicle. This marking is placed to enhance safety, particularly in areas where visibility is poor or where passing would pose a risk to drivers and pedestrians. The solid line serves as a clear visual cue to discourage risky maneuvers that could lead to accidents.

The other options refer to different situations: a dashed yellow line indicates that passing is allowed under certain conditions, a bike lane is typically marked with specific symbols or solid and dashed lines separate from vehicle lanes, and crosswalks are generally indicated by white lines on the road rather than yellow ones. Understanding the significance of line markings helps ensure safer driving practices.
