Warning signs

Bend ahead

A single dangerous bend is ahead; the symbol shows which way the road turns.

Slow down before the bend and keep within your lane. The sign gives advance warning of the change in direction.

Vienna symbol A,1b indicates a right-hand bend and may appear on a red-bordered triangle with a white or yellow background. Australia’s W1-1-L shows a black left-turn arrow on a yellow diamond.

How it looks in each country
