Went for food shopping before and a few cars in P+T and disabled spaces had big blue notes on the windowscreens.The note was basically telling the drivers that they were in breech of the conditions of using the spaces they were in and that their reg had been noted and if found to be in the spaces again they would be fined and clamped.
Must be easier to decide on people needing P+T due to the new car seat laws..plus obviously disabled ones didnt have blue badges.
