Question: 1 / 400

What does a white line on the road signify?

It separates lanes of traffic moving in the same direction

A white line on the road signifies that it separates lanes of traffic moving in the same direction. This is an important safety feature in roadway design, as it helps to clearly delineate where vehicles should be positioned in their lanes, ensuring smoother traffic flow and reducing the chances of side-swipe collisions.

Understanding the function of road markings, such as white lines, is crucial for maintaining safe driving practices. Although other road markings serve different purposes, such as indicating crosswalks or marking the road's edge, a continuous or dashed white line specifically indicates lane separation for lanes moving in the same direction. This allows drivers to navigate safely while maintaining awareness of their surroundings and the positions of other vehicles.
