The Double Bend Ahead Warning Sign – Diagram 513-B is a permanent UK road sign used to alert drivers to two consecutive bends ahead, with the first turning to the right.

The sign is available in six standard triangular sizes: 450mm, 600mm, 750mm, 900mm, 1200mm, and 1500mm, with mounting options including channel fixings, plate-only, or self-adhesive systems. Suitable for both permanent installations and temporary deployments.
