This is the dramatic moment passengers chased an out-of-control bus that had a brake failure while crossing a bridge in China.

The Starliner bus went for a stopover when it rolled away from the side of the road causing commuters, the driver, and traffic officers to run after it in Zhejiang province on May 26.

Footage shows the yellow bus moving along the road with dozens of people trying to catch up to it behind.

Some of the passengers joined the chase and grabbed onto its back in a bid to slow it down. The brave traffic officers went to its front to push it but to no avail.

Local authorities said: ‘The traffic police were in front to clear the road, and there were also highway management department personnel, and passengers who went to help.'

The driver managed to climb back inside the bus to stop it but the brakes had malfunctioned.

When the road levelled out, the bus stopped and it was towed back to the station. No one was reported hurt and a replacement bus arrived to collect the stranded passengers safely.
