No-one was hurt when a double-decker bus crashed into two cars and some railings in Emersons Green, on the northern outskirts of Bristol, at around 2.40pm on Monday afternoon.
A witness said that the driver of the number 48 bus said he caught his foot between the brake and accelerator pedal.
Resident David Wybourn said the crash sounded "like thunder".
A First West of England spokeswoman said: "We can confirm that one of our vehicles, operating on Service 48 in Bristol, was involved in an incident on Monday afternoon.

"There were two passengers on board the bus at the time, neither they, nor the driver, have reported any injuries as a result of the incident.
Incidents such as these are incredibly rare with the bus remaining one of the safest forms of transport in the UK."
