It is also illegal to overtake on any part of the crossing - either moving vehicles, or the closest stopped vehicle. Even if you can't see anyone on the crossing, be sure not to overtake.
No you might hit a Zebra!!!!!only kidding but still no! you might hit one of those lazy ass looypop ladies who stand on a zebra crossing coz there too lazy to stand anywhere else!!!don't you just hat them!!! �200 pound a month to stand on a zebra crossing when they may aswell not be there!!!
If the road and crossing are both clear then of course you can overtake. After all, no risk of getting caught breaking the law if no one's around... ; )
