Slow down and be ready to stop for any pedestrians stepping onto, or on the crossing. This also includes people obviously waiting to use the crossing.
If there is no raised traffic island in the middle of the crossing, stop and give way to pedestrians on any part of the crossing
If there is a raised traffic island in the middle of the crossing, stop and give way to pedestrians on your half of the road
Wait until the pedestrian has crossed in front of you and is clear of your vehicle before you proceed - see give way rules.
If you find yourself in a queue of traffic near a pedestrian crossing, don't move onto the crossing if there isn't enough room for your vehicle on the other side of the crossing. Do not overtake a vehicle that has stopped at a pedestrian crossing.
