You may cross solid yellow lines:
- To pass traffic moving in the same direction.
- During daylight hours only.
- At any time.
- When making turns. ✓
Answer: D. When making turns.
You may cross solid yellow lines when you are making a turn.
Why this is the answer
The Florida handbook says vehicles on either side of double solid yellow lines must not pass or cross them, but it lists an exception: you may turn left when it is safe. Making a turn requires crossing those lines, so that is the permitted reason among the choices. The passage does not allow crossing them to pass traffic going the same direction, does not limit the exception to daylight, and does not permit crossing them at any time.
Why the other answers are wrong
- A. To pass traffic moving in the same direction. — Yellow lines separate traffic moving in opposite directions, and the handbook does not allow crossing the solid yellow line to pass traffic moving in your direction.
- B. During daylight hours only. — The handbook ties the exception to turning when safe, not to daylight hours, so there is no daylight-only rule here.
- C. At any time. — Crossing at any time is too broad because the handbook prohibits passing or crossing the solid yellow lines except for the stated turn or bicyclist exception.
Remember it
Picture a left turn: cross the solid yellow line to make the turn, not to pass someone.
