What do yellow lines on a road signify?

1. Traffic moving in the same direction

2. Traffic going in opposite directions

3. A no-passing zone

4. Sidewalk separation

The correct answer is: Traffic going in opposite directions

Yellow lines on a road are used to indicate that traffic is moving in opposite directions. This is particularly important for maintaining safety while driving, as it helps drivers understand the flow of traffic and stay in their designated lanes. These lines are crucial in situations where vehicles are traveling towards each other, providing clear visual guidance that aids in avoiding head-on collisions. In contrast, other types of lines on the road serve different purposes. For example, white lines generally indicate traffic moving in the same direction, and dashed yellow lines can indicate permitted passing zones, while solid yellow lines signify that passing is not allowed. Additionally, sidewalk separation is handled by physical barriers or markings other than lines on the road. Recognizing the meaning of road markings, such as yellow lines, is essential for responsible driving and adhering to traffic laws.
