Traffic Signals Ahead Sign – Diagram 543 | Temporary UK Traffic Sign


The Traffic Signals Ahead Sign – Diagram 543 is a UK temporary warning sign used to inform drivers of upcoming traffic signals. Displaying a red-bordered triangle with a standard traffic light symbol, this sign ensures drivers reduce speed and prepare for signal-controlled junctions or roadworks ahead—especially where visibility may be limited.

Compliant with TSRGD Diagram 543 and Chapter 8 of the Traffic Signs Manual, this sign is essential for managing temporary traffic control schemes. It is widely used at roadworks, temporary intersections, or during phased road maintenance where portable traffic lights are deployed.

Available in RA1 (urban/low speed) and RA2 (high speed) reflective finishes, this sign is constructed from Zintec, GRP, composite boards, 3mm plastic (RA1), 5mm plastic (RA2), or self-adhesive vinyl. Mounting options include plate-only, riveted-in-frame, quick-fit frames, and self-adhesive (stickers only).


🔧 Technical Review

Diagram 543 is vital in temporary situations where standard driver expectations are altered. It is especially useful where temporary lights may not be clearly visible due to bends, gradients, or work equipment. Its reflective face enhances nighttime visibility and supports safe traffic flow management under Chapter 8.
