Warning signs for road work

What should you do?

Be ready to stop and wait your turn, and only proceed when the signal or operator allows.

How to recognise it

Orange diamond with a single black upward arrow.

Common confusion

A single upward arrow is not a one-way street sign; traffic will come the other way when it is their turn.
