Steep Hill Downwards Ahead road sign

The Steep Hill Downwards Ahead Sign (DoT 523.1) warns drivers that a steep downhill gradient is approaching, encouraging them to reduce speed and prepare for descent. The gradient is shown on the sign as a percentage, making the severity of the slope clear to approaching drivers.

The warning sign is useful on rural and hilly roads where a steep descent may not be immediately obvious to approaching vehicles. It’s also important for HGVs, buses, and vehicles towing trailers, as heavier vehicles require greater braking distances and careful speed control when travelling downhill.

This triangular warning sign features a black gradient symbol within a red border. Manufactured in the UK with durable materials, it has a RA2 reflective face to help it remain visible in poor weather and low-light conditions.

For the opposite direction, we also supply the Steep Hill Upwards Ahead Sign (Diagram 524.1), designed to warn drivers of a steep ascent ahead.

Sizes available: 450mm, 600mm & 750mm. Other sizes are available on request. Can be supplied for wall mounting or with rear channels for post fixing.
