Quayside or river bank

The quayside or river bank sign warns that the road ahead runs to the edge of a quay or a river bank, where it drops into water. Slow down, keep to the road and be ready to stop, especially at night or in poor visibility, when the edge is hard to see.

Official Highway Code caption: “Quayside or river bank.”

Listed under “Mostly triangular” in The Highway Code: traffic signs (GOV.UK). For every sign in more detail, see the Department for Transport’s Know your traffic signs.
