Hairpin curve: What message does this sign give drivers?
Correct answer: A hairpin curve lies ahead.
Answer options
AA hairpin curve lies ahead Correct
BA winding road lies ahead
CU-turns are permitted ahead
Why
An arrow that doubles back on itself shows a hairpin curve, where the road reverses direction in a tight U shape. Cut your speed well before it and stay in your lane all the way around; this is a warning, not permission to make a U-turn.
