Ok people now me and william_storm was arguing about the red "L" and green "P" stickers that you can see attached to peoples car. Now im saying how the "L" stands for learning and the "P" stands for pass but William_Storm was saying how "L" stands for learning while "P" stands for provisional!! What do you think???
P stands for new driver, dunno what the P actually stands for but pass is more likely than provisional edit: http://en.wikipedia.org/wiki/L-plate
