What does a solid white line on the roadway indicate?

  1. Separation of traffic lanes moving in opposite directions

  2. A stop line at a crosswalk

  3. A safe passing zone

  4. Separation of traffic lanes moving in the same direction

The correct answer is: Separation of traffic lanes moving in the same direction

A solid white line on the roadway indicates a separation of traffic lanes moving in the same direction. This option is the correct one because solid white lines are used to mark the edges of lanes and indicate that vehicles should not cross them unless they need to make a turn. Option A is incorrect because solid white lines are used for lane separation, not separation of traffic moving in opposite directions. Option B is incorrect because stop lines at crosswalks are typically painted with solid or dashed white lines, not solid white lines. Option C is incorrect because solid white lines do not indicate safe passing zones, which are usually marked with dashed white lines or signs.
