End of 30 MPH Minimum Speed Limit Sign – Diagram 673 | Permanent UK Traffic Sign
The End of 30 MPH Minimum Speed Limit Sign – Diagram 673 is a UK regulatory traffic sign that signifies the cancellation of a previously enforced minimum speed requirement. Featuring a white “30” on a blue circular background with a bold red diagonal slash, this sign informs drivers they are no longer required to maintain a minimum speed of 30 miles per hour.
This sign is fully compliant with TSRGD Diagram 673 and specified in Chapter 3 of the Traffic Signs Manual. It’s commonly used after tunnels, managed lanes, and special-use carriageways where a minimum speed was previously enforced.
Constructed using RA1 and RA2 reflective materials, the sign is available in various sizes and manufactured from durable Zintec, GRP, composite board, 3mm or 5mm plastic, or self-adhesive vinyl. It can be supplied as plate-only, riveted in a frame, quick-fit, or sticker-based, depending on your installation needs.
