What does the solid white line indicate on the road?
Traffic moving in opposite directions
Lanes in the same direction
Pedestrian crossing areas
End of a lane
The correct answer is: Lanes in the same direction
A solid white line on the road is used to indicate lanes moving in the same direction. This line serves as a boundary for lane discipline, meaning that while drivers can travel in the same direction as the adjacent lane, they should not change lanes unless it is necessary and safe to do so. It helps maintain orderly traffic flow and ensures that drivers are aware of where they are in relation to other vehicles. In contexts where lane changes are discouraged, the solid white line acts as a visual guide to keep drivers within their designated lanes, promoting safety and preventing conflicts between vehicles traveling side by side. Understanding this can help drivers navigate the roads with greater awareness of traffic rules and lane usage.
