A runaway bus careered out of control for more than 100 yards in Paisley on Wednesday.
The bus rolled down a hill before coming to a rest when it hit two cars at Thrushcraig Crescent at around 3.55pm.
The driver, who took ill at the wheel, was said to be in his 50s, was taken to the RAH but his condition was not thought to be serious.
A witness who spoke to the Paisley Daily Express newspaper said “When it all started, the bus driver looked as if he was staring straight ahead, then he was slumped over the wheel.
“The bus started to career down the hill. I heard a van blaring its horn and wondered why the bus was on the wrong side of the road.
“It was knocking down cones. It took out the traffic management system and started hitting railings and dragging wheelie bins.
“Folk were chasing it down the hill. I was horrified because it was unfolding in front of my eyes. I kept thinking about the bin lorry accident. ”
A spokeswoman for McGill’s buses said: “We are treating this extremely seriously. Our initial review indicates the driver had no previous medical issues and was of good health.”
Police are appealing for witnesses to come forward.
