 It's 12.05 and D.C. is now handing out tickets to drivers who drive past school buses with their stop arms out and flashing. About 25 D.C. school buses are equipped with the stop arms. When buses stop to pick up or drop off students and the bus's red lights are starting to flash, a stop sign comes from the side of the bus warning drivers to stop. That system also has video recording equipment to record the license plate number of any cars that drive past while the arm is deployed.
