Overhead Electrical Cables Sign – W111 | Permanent Ireland Traffic Sign

The Overhead Electrical Cables Sign – W111 | Permanent Ireland Traffic Sign is used to warn drivers of the presence of high-voltage cables overhead, typically suspended across roadways, worksites, or rural routes. This advance warning is especially important for high-sided vehicles, such as HGVs, agricultural machinery, or construction equipment, where clearance and safety are critical.

The sign features a lightning bolt-style symbol paired with an overhead cable graphic on a yellow diamond background. This instantly recognisable symbol is outlined in Chapter 6 of the Traffic Signs Manual (TSM) and is used where electrical clearance risks exist, particularly near substations, utility crossings, and overhead transmission lines.

Proper placement of this warning sign is vital for preventing contact accidents, protecting infrastructure, and safeguarding workers and road users.

Technical Review

The W111 sign is manufactured in full compliance with EN12899-1 and the most recent TSM 2024 update. It provides essential early warning in areas with limited overhead clearance due to electrical infrastructure.

This sign is ideal for installation in agricultural zones, construction sites, and temporary traffic management schemes, particularly where mobile cranes, tipper trucks, or telehandlers are operating.
