Warning signs
Hairpin curve
What it means
A hairpin curve sign is used where the road changes direction by 135 degrees or more, nearly doubling back on itself. Here the arrow loops to the right, so slow down well before the curve.

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.
03This symbol on a yellow warning sign stands for:
- AA ramp where traffic merges from the right.
- BA hairpin curve that doubles back sharply to the right. Correct
- CA gentle curve bending slightly to the left.
The arrow rises, swings over to the right, and heads back down, which marks a hairpin: a curve where the road reverses direction almost completely. Cut your speed sharply before you enter it.
