What does a solid yellow line indicate?

A solid yellow line signifies that passing is not permitted on that section of the road. This marking typically indicates lanes of traffic moving in opposite directions, and the solid line serves as a warning to drivers that it is unsafe to cross over to the other lane to overtake another vehicle. When you see a solid yellow line, it is crucial to adhere to this rule as it is intended to enhance safety and reduce the risk of accidents, particularly in areas where visibility may be compromised or where there are potential hazards.

In contrast, other markings and signs serve different purposes. A broken yellow line typically allows for passing when safe, while road construction signs provide warnings about upcoming work zones. Speed limit changes are indicated with specific signage rather than line markings. Understanding these distinctions helps drivers navigate roads safely and responsibly.
