Got a ticket for going 61km/hr in a 40 zone in Toronto (handheld radar gun). But I know I was not going that fast. Is there anything I can do? I was trying to research the accuracy of radar guns or something along those lines.
Unless you can prove the unit was malfunctioning (and that's almost impossible to do), it will be deemed to be working properly. You're going to have to find a better defence than "I know I wasn't driving that quickly." Your best chance is that the officer's notes don't document start- and end-of-shift tests of the unit.
