FYI , In Portland, OR. If the driver is not on the pictured vehicles' registration , no citation will be issued. When there is only one registered owner and the pictured driver "appears" to be of the opposite sex, the cops here don't even try and send anything regarding a photo citation. Yet.
The traffic police have to check the security footage before issuing the ticket. The automated cameras are aimed at the drivers' tags of the vehicles tags. Once your vehicle makes a mistake the camera picks up the details and sends to the police.
