Ive found a leaflet that says basically non BSAU145d plates on the road are illegal as from november the 1st. BUT Dubmeister have developed a Pressed Alloy 'Euro' plate that when supplied by Dubmeister or one of the DVLA registered retail outlets is FULLY ROAD LEGAL, carrying all BSAU145d markings required by law, including suppliers name, post code and manufacturers name.
dubmeister.co.uk might be helpful to you peeps!
