Rule 170
Take extra care at junctions. You should watch out for cyclists, motorcyclists and pedestrians including powered wheelchairs/mobility scooter users as they are not always easy to see. Be aware that they may not have seen or heard you if you are approaching from behind give way to pedestrians crossing or waiting to cross a road into which or from which you are turning. If they have started to cross they have priority, so give way (see Rule H2 ) remain behind cyclists, horse riders, horse drawn vehicles and motorcyclists at junctions even if they are waiting to turn and are positioned close to the kerb watch out for long vehicles which may be turning at a junction ahead; they may have to use the whole width of the road to make the turn (see Rule 221 ) watch out for horse riders who may take a different line on the road from that which you would expect not assume, when waiting at a junction, that a vehicle coming from the right and signalling left will actually turn. Wait and make sure look all around before emerging. Do not cross or join a road until there is a gap large enough for you to do so safely. Rule 170: Give way to pedestrians who have started to cross
