Bloody hell…….. an estimated 1 million or so cars actually being driven on the roads without any tax at all and you get shafted for a simple oversight. Boils my piss
no one has a right to drive, something all drivers would be better for remembering, I assume you have never sped, never parked on double yellows, etc etc.
to the OP, accept you screwed up and move on, you can try and appeal but this is the DVLA your an easy target because they know where you are.
Yes the police and DVLA should do something about untaxed and uninsured drivers, but they can only catch so many and as most drivers believe they have a god given right to drive and to hell with the consequences not much is going to change.
