Crosswind Sign – W166 | Permanent Ireland Traffic Sign

Crosswind Sign – W166 | Permanent Ireland Traffic Sign

The Crosswind Sign – W166 is a critical roadside warning that alerts drivers to the presence of strong lateral winds that may impact vehicle stability. These signs are commonly installed on elevated roadways such as bridges, viaducts, coastal routes, or exposed highlands — areas where sudden gusts can catch drivers off guard and make steering difficult.

This yellow diamond sign, featuring a black windsock symbol, serves as a visual cue to reduce speed and maintain heightened awareness. The W166 sign is especially vital for high-sided vehicles, trailers, and motorcyclists, who are most affected by side wind conditions. As outlined in TSM Chapter 6, it plays a key role in improving driver readiness and preventing wind-related incidents on Irish roads.
