I've had my probationary drivers licence for 6 months now, haven't had an incident until now. Driving with a friend, we floored it down a open straight Street with a speed limit of 50. I was going around 120 when I noticed a flash. It may have been the street light or it was a mobile speed camera still not sure. If I was caught, what fine should I be expecting under Traffic Law? And what are my options to appeal?
