Vehicle Length Restriction Sign – Diagram 629.1B. Used to restrict access for vehicles exceeding a specified length. Available in multiple sizes and reflective grades.
Professional design, supply, and installation of all types of traffic signs across the UK.
Learn More 🚀The Vehicle Length Restriction Sign – Diagram 629.1B is a mandatory UK road sign used to inform drivers that vehicles exceeding a specific overall length (in this case, 9.9m) are prohibited from continuing past that point. This restriction enhances road safety on routes with physical or operational limitations — such as narrow roads, sharp bends, bridges, or industrial zones.
This red-bordered circular sign includes a black lorry icon, a clearly printed length in metres, and opposing arrows to indicate the measurement applies to total vehicle length. Compliant with TSRGD Diagram 629.1B, BS EN 12899-1, and Traffic Signs Manual Chapter 3, it is a legally enforceable part of UK road infrastructure.
Manufactured using RA2 or R3B reflective sheeting, this sign is available in standard circular sizes from 300mm to 1500mm, and in aluminium, composite, or self-adhesive vinyl. Mounting options include channel rail, plate-only, or adhesive back for maximum site flexibility.
Diagram 629.1B is used on roads that are geometrically unsuitable for longer vehicles. It helps prevent accidents, blockages, and structural damage on narrow or constrained routes. It’s essential for logistics areas, countryside lanes, and heritage environments with older infrastructure.
