On 29 September 2023, a coach operating a school bus route overturned on the M53 motorway in The Wirral in north-western England, killing the driver and a 15-year-old passenger.

Merseyside Police announced that all students who witnessed or were involved in the incident would be provided with specialist trauma support.

[5] The crash was captured by on-board cameras on the bus which, according to Andre Rebello, the senior coroner for Liverpool and the Wirral, showed the driver collapsing at the wheel.

At the same time, the bus veered to the left, leaving the carriageway and climbing an embankment before coming to rest on its side.

Preliminary investigations suggested that Shrimpton suffered a medical episode while at the wheel and that Baker was partially ejected from the vehicle and died from head injuries sustained from the wreckage landing on her.
