I received a road side FPN for speeding a couple of months ago. I have a couple of issues with it though. 1. The officer has not signed the FPN. 2. The speed wrote on the FPN is different to that on the court prosecution letter i received. Was i supposed to be written to within 21 days of the expiry of the FPN payment date? Just to add, I refused to sign the FPN when I was given it as the officers were very abrupt. Where do i stand, can anybody help?
