What does a solid yellow line indicate?

  1. No passing zone for traffic moving in either direction

  2. Passing zone for traffic moving in either direction

  3. No passing zone for traffic moving in one direction

  4. Passing zone for traffic moving in one direction

The correct answer is: No passing zone for traffic moving in either direction

A solid yellow line indicates a no passing zone for traffic moving in either direction. This means that drivers are not allowed to cross the line to overtake or pass other vehicles in either direction. Options B, C, and D are incorrect as they suggest that a solid yellow line indicates a passing zone, which is incorrect. This could be dangerous as it would allow drivers to pass in areas where it may not be safe to do so. It is important to follow the rules for passing to ensure the safety of all drivers on the road.
