(Salem, OR) -- Two of Salem's photo enforced red light cameras will start issuing tickets for speeding. The northbound-facing cameras at Commercial Street and Kuebler Boulevard and Commercial Street at Madrona Avenue will issue tickets for both running red lights and speeding. Starting today through May 30th, warnings will be issued for both violations. A police officer verifies the violation before a ticket is sent in the mail to the vehicle's registered owner. Over the 17 years the cameras have been in place there's been a steady decrease in crashes.
