What should you do when you see a solid white line on your right?

Seeing a solid white line on your right indicates a boundary that should not be crossed unless absolutely necessary. This line is commonly used on roadways to delineate lanes where lane changes are discouraged, such as near the edge of the roadway or when approaching a restricted zone. The solid nature of the line signifies that crossing it could lead to safety hazards or violations of traffic laws.

Driving behavior around solid white lines is guided by safety considerations, emphasizing the importance of staying within designated lanes. This helps maintain traffic flow and reduces the risk of accidents. Therefore, the proper action is to refrain from crossing this line unless a legitimate and safe reason arises, such as avoiding an obstacle.
