Is there a penalty for displaying different plates (ie not corresponding to your licence) on your bike/car? I was just wondering as i'm coming up to my green p's in the car and have no more red p's hanging around for the motorbike. Would it be a big deal if i put green p's or even L's on the bike dispite having only a P1 licence? You see parents runnning around with L plates on all the time because they're too lazy or stupid to take them off, and i imagine that putting an L plate on wouldn't be a big deal, but would putting a Green P plate on incurr a fine/demerit points? Sort of confusing question... Thanks guys.
