Not AFAIK. The police tried to bluff people by quoting a similar case recently as proof that the loophole is closed. It has not been though. They are just bluffing and dont know the law too well themselves. There is NO requirement at present to sign the statement of driver identity although there IS a legal requirement to supply the information to the best of your knowledge. Im in the middle of a legal wrangle over this at the moment as I refuse to sign a statement that I know to be false - eg. I am pleading not guilty to a speeding charge and have already said I will not accept any offer of a fixed penalty. Therefore if the CPS intend to pursue the case, it will go to court, where a signed statement of guilt will go against a not guilty plea. It is my right to plea not guilty unless they have evidence beyond reasonable doubt that I committed the alleged offence. Which to my knowledge they do not have, and if they do, it is also my right to see their evidence before the court date.
