Learn More 🚀The No Stopping on Main Carriage Way Sign – Diagram 642 is a mandatory UK road sign used to prohibit vehicles from stopping at any time on the main carriageway. This sign is vital for ensuring clear traffic flow and safety on key routes, particularly dual carriageways, clearways, and high-speed roads.
Fully compliant with TSRGD Diagram 642, BS EN 12899-1, and Chapter 3 of the Traffic Signs Manual, this blue circular sign is overlaid with a red border and cross to indicate an absolute no-stopping restriction.
Manufactured in the UK using RA2 or R3B reflective sheeting, it is available in standard circular sizes from 300mm to 1500mm, and constructed from aluminium, composite, or self-adhesive vinyl. Offered with multiple mounting options including channel rail, plate-only, or adhesive backing.
Diagram 642 enforces a 24/7 no-stopping zone and is used in high-risk areas where any vehicle stoppage may obstruct traffic or pose a safety hazard. It is most commonly seen on urban clearways, major dual carriageways, and near junctions where stopping must be strictly avoided.
