What does a solid white line indicate on the road?

1. Zone for pedestrians only

2. Lane separation; do not change lanes

3. Allowed area for merging

4. Place to park temporarily

The correct answer is: Lane separation; do not change lanes

A solid white line on the road serves as a critical visual guideline for drivers regarding lane usage. Specifically, it indicates that the lane is separated for a reason, and changing lanes across this line is discouraged or prohibited. This is generally to maintain safety and order on the road, as crossing a solid white line could lead to potential conflicts with other vehicles or disrupt the flow of traffic. In many cases, these lines are used in areas such as highways or multi-lane roads where there's a need for lane discipline, particularly near exits or other merging traffic. Understanding the purpose of solid white lines is essential for safe driving, as it helps maintain clear boundaries for where vehicles should remain. It emphasizes that drivers should stay in their lanes and not attempt to change lanes, ensuring safer navigation through various traffic situations. Other options do not accurately describe the role of a solid white line, such as indicating pedestrian zones or allowing merging, which could mislead drivers about the intended traffic control.
