Photo radar is enforcement that captures a photograph of a speeding vehicle.
As a vehicle enters the radar beam it is detected and the speed is calculated. When the end of the vehicle is detected and if that vehicle’s speed exceeds the posted speed limit for the particular location, the system sets off an audible alarm and takes a photo. During low light periods, a flash is incorporated to enhance the image.
When in use, a photo radar vehicle it usually manned by a Community Peace Officer who sets up and tests the equipment. The officer also reviews every picture to verify that a traffic violation has occurred. Once a violation is verified, a ticket is issued and mailed to the vehicle's registered owner.
There are three (3) photo radar vehicles used in the City of Lethbridge.
