Warning Sign/Side Winds

Pre-Worboys sign

There doesn't seem to be a pre-Worboys sign for side winds.

Worboys Report sign

The sign for side winds depicts a wind sock blowing in the breeze, from left to right. Whilst it may appear a sensible idea to reverse the sign depending on the prevailing wind conditions, this does not appear to happen.

The sign is often used on exposed bridges and less frequently on coastal or hill roads where high sided vehicles may be subjected to buffeting from strong winds. On a number of motorways, this vague warning is replaced by an actual windsock mounted on the verge to provide a real visual idea to lorry drivers of the current wind conditions and so allow them to adjust their driving accordingly.

Irish sign

The Irish version of the sign is similar, again featuring a windsock, this time backed by the standard yellow diamond. The windsock symbol differs in detail, notably by being 'stripey'.
