This is the shocking moment a bus carrying almost 50 people narrowly avoided a serious collision on the M40. Mike Helm, the driver of the bus, captured the incident on his dashcam as the car driving ahead of him span 180 degrees. Passengers can be heard screaming as the driver shouts ‘Woah!’ when the car in front loses control. However with not a second to spare, Mr Helm managed to slam his foot onto the brake, stopping just inches from the broken down vehicle in the second lane. And (naturally), his 47 passengers were more than grateful.
