Ive recied a late notice today for not taxing my car for £80 or £40 if paid within 14 days but was not given chance to pay this penelty as my car was clamped and inpounded today.My car was insured and was going to pay penelty and tax car which I explained to the clamping firm but they said I still had to pay the penelty aswell as the release fees.I believed and understood from the late penelty letter that I had 28 days to pay and no clamp would be put on my car but ive now been told ive got this wrong and the penelty was just for tax backdated I owed .This seems harsh please can anybody tell me the laws
