21. At traffic lights.   There may be special signals for pedestrians. You  should only start to cross the road when the green figure shows. If you have started to cross the road and the green figure goes out,  you should still have time to reach the other side, but do not delay.  If no pedestrian signals have been provided, watch carefully and do  not cross until the traffic lights are red and the traffic has stopped.  Keep looking and check for traffic that may be turning the corner.  Remember that traffic lights may let traffic move in some lanes  while traffic in other lanes has stopped.  highwaycodeuk.co.uk 13
