The pre-Worboys bend sign bore a diagram symbolising a road, pointed at the top and with a "fishtail" at the bottom, curving to either the left or the right above the text "BEND" on a plate mounted below the standard red warning triangle.
The bend warning sign introduced in 1964 features a similar pictorial representation, though now minus the fishtail and straightened before and after the curve (diagram 512). No text is needed to display "BEND", however supplementary plates are common with dangerous/notable corners.
Junction on bend
A later addition to the bend warning signs were symbols to show junctions on bends, both inside and outside. Diagram 512.1 shows a junction on the outside of a bend and 512.2 shows a junction on the inside of a bend, with the symbol shown bearing left or right as appropriate.
As of 2016, diagram 512.3 was introduced, depicting a crossroads on a bend ahead.
