Learn More 🚀The Steep Hill Upwards Ahead Warning Sign – Diagram 524.1 is a UK-compliant road sign used to warn drivers of a steep incline on the road ahead. It helps prevent surprise acceleration or engine strain by encouraging early gear changes and speed adjustments—especially vital for HGVs, towing vehicles, and cyclists.
Fully compliant with TSRGD Diagram 524.1, BS EN 12899-1, and Chapter 4 of the Traffic Signs Manual, this permanent warning sign is made from high-durability aluminium or composite substrates with RA2 or R3B reflective sheeting for maximum visibility in all weather conditions.
This sign is available in the full range of standard UK triangular sizes — 450mm, 600mm, 750mm, 900mm, 1200mm, and 1500mm — and can be installed using channel fixings, plate-only fittings, or self-adhesive methods. Suitable for both permanent installation and temporary traffic management projects.
The sign displays a bold black slope angled upwards from left to right, with a percentage value indicating the gradient (e.g. 20%). Enclosed in a red-bordered triangle, it delivers a clear message of uphill severity to all road users.
