Rule 8
At a junction. When you are crossing or waiting to cross the road, other traffic should give way. Look out for traffic turning into the road, especially from behind you, and cross at a place where drivers can see you. If you have started crossing and traffic wants to turn into the road, you have priority and they should give way (see Rules H2 and 170).
Rule 19
Zebra crossings. Give traffic plenty of time to see you and to stop before you start to cross. Vehicles will need more time when the road is slippery. Wait until traffic has stopped from both directions or the road is clear before crossing. Remember that traffic does not have to stop until someone has moved onto the crossing. Drivers and riders should give way to pedestrians waiting to cross and MUST give way to pedestrians on a zebra crossing (see Rule H2). Keep looking both ways, and listening, in case a driver or rider has not seen you and attempts to overtake a vehicle that has stopped.
