Maximum Vehicle Width Sign – W113 | Permanent Ireland Traffic Sign
The Maximum Vehicle Width Sign – W113 | Permanent Ireland Traffic Sign is used to notify drivers of a width restriction ahead, indicating the maximum allowable width for safe passage through a roadway, underpass, bridge, or narrow urban street. This warning sign is vital for preventing collisions, infrastructure damage, and traffic blockages caused by oversized vehicles.
This sign displays a black numeric width (e.g., 2.15m) between two black inward-pointing arrows on a yellow diamond background, ensuring instant recognition and visibility. Fully outlined in Chapter 6 of the Traffic Signs Manual (TSM), it provides critical guidance for drivers of HGVs, buses, agricultural machinery, and wide-load vehicles.
Advance display of W113 allows drivers to take alternative routes when necessary and ensures safer navigation through constrained road environments.
Technical Review
The W113 sign complies with EN12899-1 and TSM 2024 standards, ensuring durable construction and legal validity on Irish roads. The maximum width figure is fully customisable (e.g., 2.15m, 2.50m, etc.), based on the specific clearance available on the roadway.
Commonly used on old bridges, town centre laneways, rural stone archways, and temporary traffic management setups, this sign is often accompanied by supplementary warning signage or diversion markers.
