Washington Written Drivers Permit Practice Test

What do solid yellow lines mark on the road?

1. Acceleration zones

2. Passing zones

3. End of the road

4. Lane dividers

The correct answer is: Lane dividers

Solid yellow lines on the road indicate lane dividers. They are used to separate lanes of traffic that are moving in opposite directions. Crossing a solid yellow line is usually not allowed, as it indicates that it is unsafe to pass or change lanes at that point. This helps in maintaining organized traffic flow and preventing accidents. Options A, B, and C are incorrect: A. Acceleration zones are not marked by solid yellow lines on the road. B. Passing zones are typically marked by broken yellow lines, not solid yellow lines. C. The end of the road is usually indicated by a different type of marking or signage, not solid yellow lines.
