Just a word, of caution, many are advising that this will basically be an "automatic drop" by the crown. It will depend if the ticket notes indicate that the officer was aware at the time of the offence that you had received the warning, on the previous Friday. IF he ran your plate and the warning popped up and the officer made note of that on the ticket the crown "may" be less likely inclined to drop it.
I understand you had ordered the parts, Hopefully you ordered a STOCK fender, BUT you had been warned that riding with it in the current location was illegal and you choose to continue to ride it in that state. Unless you want another ticket, until that STOCK fender arrives take a drill drill new holes for the current brackets and at least move the plate to the rear most point you can properly secure it.
He knew about the warning beforehand because I told him. He acted like he wasn't going to ticket me but when he came back after 30 mins, he issued me the ticket. I had to remind him that I received a warning 2 days before! He was acting clueless... On the ticket it says "Drive motor vehicle, plate improperly displayed"
