    Pass either side — blue and white circle UK road sign

    Featuring two white arrows pointing diagonally downward to the left and right on a blue circle, this sign permits drivers to pass on either side.

    It is positioned at central traffic islands, lane separators, and entrance channels to gyratories or petrol stations where both paths lead to valid lanes.

    What this sign means

    Traffic may pass on either the left or right side of the island or obstruction.

    Both routes beyond the sign lead to the same destination or continuing traffic stream.

    • Blue circular sign with two white downward-diverging arrows.
    • Permits passing on either the left or right side.
