What does a solid yellow line indicate?

A solid yellow line is a vital road marking that indicates no passing is allowed for vehicles traveling in the direction of the line. This marking serves as a clear warning to drivers that overtaking another vehicle is prohibited for safety reasons, typically due to limited visibility or other hazards ahead. The intent behind this rule is to help prevent accidents that could occur when vehicles attempt to pass in areas where it is unsafe to do so.

The presence of a solid yellow line often indicates that the lane is in a location where vehicle interactions could lead to dangerous situations, such as on curves or near intersections. This ensures that drivers remain cautious and adhere to the regulations designed to ensure the safety of all road users. Understanding these road markings is crucial for safe driving practices.
