20 mph zone sign

What it means

The sign marks the entrance to an area with a 20 mph speed limit. It also warns that there may be traffic-calming features, which might not be signed individually.

Inside the zone, keep to a steady low speed rather than speeding up and slowing down between humps and narrowings.

The zone might include 20 mph repeater signs and road markings. A separate sign shows where the zone ends and the next speed limit begins.

The lower panel can show a local name or emblem; the one in the official artwork is just an example.

Where you'll see it
