During a regular bus trip through the city, the bus driver took a seemingly normal turn, passing over railroad crossing and doing a U-turn onto the next street, when the momentum of the turn caused the driver to slide from her seat and send the bus drove over a concrete barrier onto exposed railroad tracks while trying to maintain control of the vehicle. Bus CCTV footage shows the bus driver falling from her seat – all because her seat belt wasn’t fastened -and losing control of the bus.
