If I were to.....................

all i know is what advanced police motorcyclists have said, you can overtake all vehicles apart from the lead vehicle when in a zigzag area.

that's what I was told on my advanced course....................the odd thing tho is that peeps on here seem to think its the car stopped at the lights........well what about the cars on the other side of the crossing but still in the zigzags?
potentially you pull up just shy of the car at the crossing and the lights change.......you have to pass him........the crossing can't have any relevance, it has to be the car at the front of the zigzags

the Police rider we had used to go through the law asking us questions about this that and the other........there was always an exception to every rule you couldn't break
eg. "You must not cross/overtake on a solid white line"
but you can if its a cyclist doing less than 12mph (?????FFS how do they make these rules?) amongst others

The zigzags aren't there to indicate where you can and can't overtake, they have no bearing on overtaking, they are there as an absolutely no parking zone to keep the crossing clear for cars and pedestrians to be able to see each other without obstructions. Hence yellow zigzags outside schools.
