Got pulled by 2 stupid police 'persons' in Motherwell last week. The reason? They thought my tax disc was 2yrs out of date!!! LOL! Apparantly it's 2yrs since purple discs were issued, but the 2007 discs are purple & I bought mine on 16th January (1st possuble day) They were quite dismissive and said 'well, you'll prolly get stopped for it again'
Note to police persons, make sure you know your 'colours' LOL
