What do white lines on a road indicate?

1. Traffic traveling in different directions

2. Traffic going in the same directions

3. A stop line for vehicles

4. Pedestrian crossing zones

The correct answer is: Traffic going in the same directions

White lines on a road indicate that traffic is going in the same direction. This is vital for maintaining orderly flow and safety on multi-lane roads. For example, when you see white dashed lines, they often separate lanes of traffic moving in the same direction, allowing drivers to change lanes as necessary. Solid white lines usually mark the edge of travel lanes and discourage crossing, further emphasizing the same-direction flow of traffic. Other options, such as indicating traffic traveling in different directions, are represented by yellow lines instead, which denote separation between opposing flows of traffic. Stop lines and pedestrian crossings are marked by different types of lines or symbols, typically using vertical or horizontal markings rather than solely relying on the color and type of line. This distinction helps drivers understand how to navigate the roadway appropriately and safely.
