I was cited for going through a left turn arrow/red light. The alleged violation was video taped by camera, but was obscured by a truck in the adjacent lane. After reviewing the video 15-20 times, it is my opinion that I was already in the intersection when the light turned red; however, it could not be established conclusively because the truck blocked the view of the front of the vehicle. The law enforcement person reviewing the tape to establish the validity of a volation could not see the front of my vehicle relative to the white line which establishes a violation. Since this is clearly a judgment call, shouldn't the tie go to the runner ? Since I am a retired member of the U.S. military with a 30 year record of following rules and a 60 year driving record without a similar violation, does my defense seem reasonable to contest this citation ?
