A good friend has received a ticket ($361 and 3 demerit points) for allegedly running a red light.

They're pretty unimpressed, because they remember the car trip in question very clearly, and when turning right, they saw the flash of the camera, and mentioned to their spouse (in the car) that the camera was a bit eager, as they were half way through the intersection when the light went red. They say that the light was definitely amber when they entered the intersection.

They have an almost spotless record, and quite frankly don't want to be paying hundreds of dollars (and losing points) for something they didn't do.

I could easily refer them to a lawyer, but at the end of the day that's going to cost them more than the ticket. I don't know anyone who does stuff like this for free.

Who has challenged (or negotiated) something like this before?

Any tips I can pass on?
