This sign means?
- Left turn prohibited
- Do not turn to go in the opposite direction. (U-turn) ✓
- Road slippery when wet
- Right turn prohibited
Answer: B. Do not turn to go in the opposite direction. (U-turn)
The sign means you must not make a U-turn, that is, do not turn around to go in the opposite direction.
Why this is the answer
The handbook's U-turn section tells you to check for a sign saying not to make a U-turn before you turn around. It also explains that regulatory signs give a direction that must be obeyed, and that a red circle crossed by a line tells drivers the activity pictured is not permitted. Read together, a sign that shows a U-turn with a prohibition means turning around to go the opposite way is not allowed there. That matches the bank answer.
Why the other answers are wrong
- A. Left turn prohibited — A left-turn prohibition is a different restriction; the passages link the U-turn sign to checking for a sign that forbids turning around, not to banning ordinary left turns.
- C. Road slippery when wet — Slippery-road warnings are warning signs about conditions, while this sign is a regulatory prohibition on turning around, so road slippery when wet does not match the bank answer.
- D. Right turn prohibited — A right-turn prohibition concerns turning right at an intersection, not turning around into the opposite direction, so it is not the meaning given.
Remember it
Think no turning back for a U-turn sign with a prohibition mark.
