What does a solid yellow line on a road indicate?

Answer: B — No passing is allowed in your lane

A solid yellow line on a road indicates that no passing is allowed in your lane. This marking is placed to enhance road safety by clearly signaling to drivers that it is not safe to overtake another vehicle in that section of the road. It typically appears on two-lane roads or multilane roads and is primarily used in scenarios where visibility is limited or where there may be increased risk due to curves, hills, or intersections ahead. The intention behind this marking is to prevent dangerous maneuvers that could lead to collisions. In contrast, if a road has a broken yellow line, it indicates that passing is permissible when it is safe to do so. Therefore, the solid yellow line serves as a crucial visual cue for drivers to maintain safe driving practices and avoid potential accidents.
