Learn More 🚀The Slippery Road Ahead Sign – Diagram 557 is a temporary UK road sign used to warn drivers about slippery road surfaces caused by rain, oil spills, loose materials, or temporary works. Featuring a tilting car with skid marks inside a red-bordered triangle, it is designed to prompt caution and reduced speed in high-risk conditions.
This sign complies with TSRGD Diagram 557 and is recommended in Chapter 8 of the Traffic Signs Manual for temporary traffic management. It is widely used during resurfacing, after gritting, or in areas prone to wet-weather skidding—particularly when road grip is temporarily compromised.
Available in RA1 (urban/low-speed) and RA2 (high-speed) reflective finishes, this sign is constructed using Zintec, GRP, composite, 3mm plastic (RA1), 5mm plastic (RA2), or vinyl sticker substrates. Mounting options include plate-only, quick-fit, riveted frame, or self-adhesive (for sticker signs).
Diagram 557 is crucial during adverse conditions and surface maintenance, helping prevent vehicle skidding and collisions. It’s highly visible and understood by all drivers, making it an essential warning during surfacing works, wet-weather hazards, or vehicle fluid contamination.
