When I appeared infront of the Crown last month, I didn't even have to plead my case.
He said, "how about I drop all 3 demerits and you pay the full fine". I was more than happy to take the deal. I was also going 20 KM/H over. The painful part was the waiting in that tiny hallway with 50 other people, probably the longest hour ever.
It was also the first time I had been pulled over. I think your driving record also weighs in on the Crown's decision.
