Regulatory signs

Keep left

A blue circle with a white arrow pointing diagonally down to the left. Tells you to pass the obstacle on your left-hand side. Most common on the front of traffic islands and pedestrian refuges in the middle of the road. Driving on the wrong side of one is dangerous and a road traffic offence.
