What does a solid yellow line on the road indicate?

A solid yellow line on the road indicates that no passing is allowed. This marking is used to signal to drivers that the road ahead may have conditions that make passing unsafe, such as curves, hills, or intersections where visibility is limited. The solid line serves as a visual cue to maintain safe driving practices and to prevent potential accidents resulting from unsafe overtaking maneuvers.

In general traffic markings, solid lines contrast with broken lines, which indicate that passing is permitted under certain conditions. Solid yellow lines are particularly important for ensuring that drivers respect the rules of the road and prioritize safety, especially in areas where visibility and road conditions can significantly impact driving decisions. The presence of such a line helps to maintain order on the road and protect all road users.
