I heard recently that they are deciding whether to make an addition to the highway code whereby if you are turning into a side road and a pedestrian or cyclist is about to cross you MUST give way. Like a lot of people I have spoken to I teach my pupils to look into the road for pedestrians about to cross and when approaching take extra care to check mirrors for cyclists or stay behind a cyclist who is in front until they have passed the junction. I thought this was already a law but apparently not. Here is what the highway code says.
Rule 170: Take extra care at junctions. You should
watch out for cyclists, motorcyclists, powered wheelchairs/mobility scooters and pedestrians 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
watch out for pedestrians crossing a road into which you are turning. If they have started to cross they have priority, so give way
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.
So it seems this little bit of common sense we have been teaching is overkill at the moment and a few tests I have heard of that have failed (due to a pedestrian approaching the road junction and NOT actually started to cross) may actually be technically a pass.
