 11 cameras are coming to six Arlington intersections this year, including this one here at 10th Street North and North Barton Street. This is an additional tool for all of us to use to help make sure our roadways are safer. That's Ashley Savage with Arlington County Police. If you come to a red light and you enter the intersection after the light has turned red, that is what triggers the camera to be activated and the camera takes a photo as well as video of the vehicle.
