How much over the speed limit can I go before getting a photo radar ticket?
While no city we asked or guideline lists a specific number, Edmonton records show that since 2014 no speed camera tickets have been issues for going five kilometres or less over the limit

Only Toronto gave us an answer: 15 kilometres an hour over the limit.
Unlike a speed camera, a police officer has some discretion when pulling over speeders and generally uses some common sense. Let’s say a group of vehicles is travelling 65 kilometres an hour in a 60 zone. The common sense reaction would be to let them go and pull over the car that’s going a lot faster and zipping in and out of traffic. But a speed camera doesn’t have common sense and will trigger a ticket based on a set speed. So what is the standard set point? It’s easy to say that if you don’t speed, you won’t get a ticket – but in practice, isn’t keeping up with the general speed of traffic both more practical and safer? – Ralph, Edmonton
Edmonton records from 2014 show that just over 13 per cent of tickets that year were for speeding six to 10 kilometres an hour over the limit and none were issued for drivers going five kilometres an hour or less, Karim El-Basyouny, a professor of transportation engineering at the University of Alberta, said in an e-mail.
