An investigation has been launched after an empty bus rolled backwards down a road, mounted a kerb and hit a tree before shunting forward and coming to a stop.
A car nearly collided with the wayward bus and can be heard sounding its horn in a video of the bizarre moment, which has been shared online.
Luckily no one was hurt in the incident in Corporation Street, Tamworth, Staffordshire.
Student Connor Hepple, 17, was waiting for the Number 3 bus to take him from Tamworth to Coton Green when the drama unfolded and he started filming.
He said: “I was waiting for that exact bus to take me home. I saw it start to roll backwards and the steering wheel was turning in random directions. It was empty and the driver was on his break or swapping drivers.”
The incident happened at 3.30pm on September 27 and involved an Arriva Saphire single-decker bus.
Connor added: “I didn’t get on the bus. I walked home instead.”
He shared a video of the incident on Facebook captioned “self-driving buses now available”.
Connor, who is studying A-levels at King Edward VI Sixth Form in Lichfield, added: “A lot of people I know are confused about why it moved how it did.”
People can be seen running after the bus.
Cora Woodhouse, director for Arriva Midlands said: “The safety of our passengers, staff and members of the public is always our highest priority and we have launched a thorough investigation as a matter of urgency into the circumstances surrounding this incident.
“Initial investigations show that there were no technical faults with the vehicle and we cannot comment further until this investigation has been completed.”
