Tunnel Sign – W 162 | Permanent Ireland Traffic Sign
The Tunnel Sign – W 162 is a vital traffic warning sign used to inform drivers that a tunnel lies ahead, allowing them to prepare for sudden changes in lighting, visibility, or driving conditions. Featuring a bold tunnel portal icon on a high-visibility yellow diamond background, this sign is designed for instant recognition and proactive driving adjustments.
In accordance with Chapter 5 of the Irish Traffic Signs Manual (TSM), the W 162 sign is placed on approach roads to tunnel entrances, where reduced lighting, narrow lanes, or confined space can require slower speeds, dipped headlights, and heightened attention. This warning sign is particularly important for HGVs, caravans, buses, and vehicles carrying hazardous materials.
Installed in both urban and rural areas, the W 162 improves safety by reminding drivers to adapt before entering a tunnel environment where visual conditions and spatial awareness are dramatically different from open roads.
