Uneven road sign

What it means

The road surface ahead is uneven. Bumps and dips can unsettle a vehicle, especially at speed.

The bumpy shape shows a road surface that is not flat.

Slow down before you reach it. Motorcyclists and cyclists may need to change course suddenly to avoid a bad patch, so give them extra room.
