What does a solid yellow line on the roadway indicate?

A solid yellow line on the roadway indicates that passing is not permitted for vehicles in that lane. This marking is a safety measure designed to prevent dangerous situations where a driver might attempt to overtake another vehicle in a location where visibility is limited or where it is otherwise unsafe to do so, such as on curves or near intersections.

The presence of the solid yellow line signals drivers to remain in their lane and not attempt to pass vehicles, ensuring the safety of all road users. This is particularly important on two-lane roads where opposing traffic is present, as it helps to reduce the likelihood of head-on collisions.

It is also notable that while the other options might describe certain situations—such as a bike lane or the end of the road—they do not convey the specific meaning associated with a solid yellow line. Therefore, understanding these markings and their implications is crucial for safe driving practices.
