Question: 1 / 400

What does a solid white line on a road indicate?

Changing lanes is encouraged

Changing lanes is discouraged

A solid white line on a road signifies that changing lanes is discouraged. This is a critical safety measure designed to prevent drivers from making sudden lane changes that could lead to accidents. The solid line serves as a visual barrier, indicating that the area is not intended for lane shifts, often due to the nature of the road or surrounding conditions.

Solid white lines are commonly found in areas where there may be increased hazards, such as near intersections or pedestrian crossings. By maintaining the integrity of these lanes, drivers are encouraged to stay in their current lane, promoting smoother traffic flow and reducing the risk of collisions. In contrast, other types of markings, such as dashed lines, would indicate that changing lanes is permitted, but in this case, the presence of the solid line conveys a clear message to avoid doing so.
