⚠️ Steep Hill Downwards for Heavy Vehicles Sign – Diagram 583 | Permanent UK Traffic Sign

It is an official UK warning sign used to notify drivers, especially those operating HGVs, buses, and other heavy vehicles, of a steep descent ahead. This sign is crucial for road safety and traffic management, ensuring that drivers prepare for the gradient by reducing speed, selecting a lower gear, and testing their brakes before proceeding downhill. It is fully TSRGD-compliant and is commonly installed on hilly and mountainous roads, highways, and rural routes where steep inclines pose potential hazards.
