Hi all,can anybody tell me if you are allowed to overhang the bay at the front and or the back as I think you can only park adjacent (90 degrees) to the kirb and not at an angle, there are bays near my work where only a Vespa can fit and my DT looks longer please let us know

It is more about the zealousness of anyone in authority that the rules; I would suggest. I have argued a ticket or two for the side stand being outside a bay.

So if any part of my wheels are outside I'm nicked then

You leave yourself open to be nicked, yes.
