Warning Sign/Quayside

Pre-Worboys sign

There doesn't seem to be a standard pre-Worboys sign for Quayside warnings

Worboys Report sign

The Quayside warning sign warns of harbour walls, quays and so on which are unprotected by barriers. The lack of protection is generally due to the need to allow transfer of goods from boats to land, and so common in the smaller harbours around our coasts. The symbol used on the sign is the side silhouette of a car with the rear tyre sitting on a black box indicating the quay while the car nosedives towards the water below. In 1994 the car symbol was updated to be less rounded on the rear.

Irish sign

Unprotected Water sign in Dundalk

The Irish equivalent is warning sign W 160 Unprotected Water (as prescribed in the Traffic Signs Manual 2010) and, like the UK sign, features a car pivoted on the corner of a quayside and about to nosedive into water, set in the standard yellow diamond.

Watercourse alongside road

A variant of the Quayside sign, more closely related to the Soft Verges sign is that used to indicate a water course alongside the road. The design features the standard head-on silhouette of a car with the right tyre on the black box depicting the road while the left tyre is sitting on the surface of the water. The 'road' box continues on the far left of the sign.
