What does a solid yellow line indicate?

A solid yellow line indicates a no passing zone, which means that drivers are not allowed to overtake and pass other vehicles in this area. The purpose of this marking is to enhance road safety, particularly in locations where visibility is limited or where there may be an increased risk of collision, such as on curves or near intersections.

The presence of a solid yellow line signals to drivers that they should remain in their lane and not attempt to cross the line for passing. This helps prevent dangerous situations that can arise when vehicles try to overtake each other where it is unsafe to do so. Understanding this traffic regulation is crucial for making informed and safe driving decisions.
