The Washington Post's James Hohmann digs into the driving record of Carla Proctor, the Metrobus driver who was behind the wheel of the bus that struck 30-year-old jogger Amanda Mahnke on Sept. 3. Proctor had two previous on-the-job accidents: one in 2004, when she crashed a Metrobus into the back of a parked vehicle on the 1300 block of Wisconsin Ave. NW, and another in 2003, when she allegedly failed to properly apply a brake before she exited a bus to inspect a faulty door. That bus "rolled down a hill and struck a car, setting off a chain of crashes that damaged seven vehicles as well as the bus."
