A bill that would let cities use cameras to catch drivers running red lights has passed the Senate Transportation Committee. The cameras would be mounted at intersections and would most likely snap a picture of the rear license plate of any car that went through a red light. The photo would be considered proof of a violation. Fourteen states and the district of Columbia already have similar camera systems. Republican Senator Roy Terwilliger is sponsoring the bill in the Minnesota Senate, and he's on the line now.
