(Washington Examiner) — Metro has fired 20 bus drivers in the past five months after new cameras filmed them using cell phones while behind the wheel. The Metrobus cameras have caught bus drivers misbehaving 1,173 times in that period, prompting 222 suspensions for various infractions as well as the 20 firings. Aimed at the driver’s seat, the cameras are intended to help train Metro’s bus operators how to better navigate the region’s traffic-filled streets. But they also are catching drivers speeding, driving without seat belts and chatting on forbidden cell phones. The most common violation has been running red lights.
