Maximum Vehicle Length Sign – W 112 | Permanent Ireland Traffic Sign
The Maximum Vehicle Length Sign – W 112 is a critical warning sign used to indicate the maximum legal length for vehicles travelling on a particular road segment. This sign plays a key role in managing vehicle access to areas where sharp bends, narrow lanes, or restricted turning spaces make long vehicles hazardous. The sign features a truck icon, flanked by directional arrows, with a clearly displayed length measurement (e.g., 10.5m), making it immediately understandable to drivers.
In compliance with Chapter 5 of the Traffic Signs Manual (TSM), the W 112 sign is mandatory in zones where vehicle length restrictions must be observed to prevent obstruction, avoid infrastructure damage, and ensure overall traffic safety. It is particularly important in rural routes, tight urban environments, bridges, tunnels, or scenic byways where longer vehicles may become stuck or cause accidents.
Used effectively, this sign helps local authorities, contractors, and haulage managers maintain a safe and flow-efficient road network by discouraging access by over-length vehicles.
