Double solid yellow lines painted down the middle of the road mean:
- Railroad crossing ahead.
- Pedestrian crossing ahead.
- Passing is not permitted from either direction. ✓
- Passing is permitted from either direction.
Answer: C. Passing is not permitted from either direction.
Double solid yellow lines painted down the middle of the road mean passing is not permitted from either direction.
Why this is the answer
The Florida handbook says that with double solid yellow lines, vehicles moving in either direction must not pass or cross those lines. The same passage notes two limited exceptions: you may turn left or pass a bicyclist when it is safe to do so. So the general rule for traffic traveling both ways is no passing, which matches the answer about passing not being permitted from either direction.
Why the other answers are wrong
- A. Railroad crossing ahead. — A railroad crossing ahead is not what double solid yellow center lines indicate; the passage describes them as lane markings separating opposite directions of traffic.
- B. Pedestrian crossing ahead. — A pedestrian crossing ahead is not shown by double solid yellow center lines; the passage does not connect these lines to pedestrian crossings.
- D. Passing is permitted from either direction. — Passing permitted from either direction is the opposite of the handbook rule, which says vehicles moving in either direction must not pass or cross double solid yellow lines.
Remember it
Two solid yellow lines are a wall between directions: stay on your side unless you are turning left or passing a bicyclist safely.
