There are many thousands of errors on this database and also DVLA.
So long as you know who you are insured with, plod are legally obliged to check, they cannot legally tow without checking with insurer first, but I know they do.
You can claim any charges back through the county court via a summons for errors that lead you to incur expense, that's a legal right, it's not your job to check thier work.
I just had £104.40p from Norfolk Police for thier error, put simply they were offered through Crown Court Judge Judge HHJ HOLT the option of paying or meet me in court, 1 week later a cheque arrived.
Mt gf's car is still reg as unlicensed/untaxed on DVLA, even though it was taxed in APRIL 09, at a DVLA office!!
