Jamie's DT50 - he does his CBT on it on 7 January. Auntie Carole won't allow him to be insured before that because he's not allowed to ride on the road without doing his CBT. Fair enough. So the policy runs from 7 January. Can't tax the bike because he has to have valid insurance, and for the first week in January he won't. He can't do his CBT on a bike that doesn't have valid documentation, including a tax disc. FFS.
