If the cyclist is in a separate marked lane, does the rule about close passing somehow no longer apply?
e.g.
1) The cyclist is travelling towards you on the other carriageway, but is very close to the white line as he is about to turn right. Are you required to move towards the kerb to give him 1.5m+?
2) The cyclist is riding close to the centre line (his handlebar end is almost on the white line), you move completely into the other lane to overtake, must you be at least 1.5m to the right of the centre line?
3) The cyclist is wholly within a marked cycle lane at the left of the carriageway (only separated by a painted line). Must you leave 1.5m+?
4) The cyclist is within a cycle lane separated from the road by a narrow raised kerb. Must you leave 1.5m+?
I would suggest that not keeping 1.5m+ away is dangerous. In case 4) you are unlikely to hit him because of the kerb, but what if he clips that kerb and falls off?
There was a graphic shared by some Police Forces on Twitter a few years ago that states that "
If one moves into the opposing lane (to overtake) then the position of the rider (within his lane) is irrelevant". (Complete with typo on the version I link below)
