What does a white line on the road indicate?

End of the road Lane boundary Speed limit Crosswalk

Correct Answer:

Lane boundary

Explanation:

A white line on the road primarily indicates a lane boundary. This means it is used to mark the edges of traffic lanes, guiding drivers on where to position their vehicles within a lane. These lines help maintain organized traffic flow by delineating where vehicles can safely travel, ensuring that they stay within their designated lanes. When a solid white line is present, it signifies that lane changes are discouraged due to potential hazards or insufficient visibility. Alternatively, a broken white line suggests that lane changes are permitted, allowing for safe maneuvering when conditions are right. Understanding these lane markings is crucial for driving safely and effectively navigating roadways.
