Signs giving orders

Keep left

Keep left (right if symbol reversed)

What does this road sign mean?

You must pass to the left of the sign, which is normally mounted on a bollard or island in the middle of the road; the reversed sign means keep right. It is used at central refuges, at the ends of central reservations and where traffic is split around an obstruction. Approach at a sensible speed and pass on the correct side rather than cutting across the island. The similar-looking sign that lets vehicles pass on either side has arrows pointing both ways, and telling the two apart is a common theory test question.
