Pre-Worboys sign

1959 Highway Code - Roundabout.jpg

The Pre-Worboys warning sign for a roundabout featured three arrows in a clockwise circle above the text "round-about" which was over two lines.

The sign introduced in 1964 features a symbol of three lines with pointed heads in a clockwise circle within the red warning triangle (diagram 510). The lines should align with the sides of the triangle (so that the gaps are at 0, 120 and 240 degrees) although signs with misaligned symbol are often seen.

The sign is often accompanied by the reduce speed now sign, particularly on high speed or national speed limit roads.

Irish sign

N15, Ballyshannon - Geograph - 504834.jpg

The roundabout warning in the Republic of Ireland features a symbol consisting of three arrows pointing clockwise in a circle, similar to the British Pre-Worboys design, within the yellow warning diamond.
