That is for "RUNNING RED LIGHT"!!!
And running red light is DANGEROUS driving.
I don't want my insurance to go up because of those dangerous drivings hence accidents.
RED light is clear, and Speed limit signs are usually difficult to spot, especially when you are NOT familiar with that place.
As a rule of thumb, if there is school or community center in that area, speed limit usually is 40 or 50.
电子眼 is for RUNNING RED LIGHT.
Fine is close to 400 CAD?
City of Ottawa will send CAR owner a letter, with two photos attached (my co-owner actually was caught two years ago, at Bronson and Carling).
There is a site with all the "电子眼" locations. Just google...
