What does a solid line on the roadway indicate?

A solid line on the roadway serves as a clear indication to drivers that passing is not allowed. This rule is in place to enhance safety by preventing vehicles from attempting to overtake others in situations where visibility is poor or the road conditions are not conducive to safe passing. Typically, a solid line may be found on two-lane roads where one lane is designated for traffic in each direction. When you see a solid line, it means drivers should stay in their lane and not cross over, ensuring the flow of traffic remains orderly and reducing the risk of collisions.

In contrast, dashed lines indicate that passing is permitted when it is safe to do so. Therefore, understanding the meaning of solid lines is crucial for maintaining road safety and adhering to traffic laws.
