Emergency services including a specialist ambulance were called to a collision involving a car and a bus in Adversane yesterday evening (Tuesday June 18).
One man, believed to be in his 50s and local, was taken to hospital after the crash in Stane Street betwen Pulborough and Billingshurst.
More than 30 staff from Sussex Police, West Sussex Fire and Rescue Service and South East Coast Ambulance (SECAmb) attended the scene at around 6.30pm.
Martin McKilligin, watch commander at Storrington, said the man suffered an open fracture to his ankle possibly when using his brakes.
The front of victim’s Mercedes and the back of the bus were both severely damaged in the collision.
“Because the gentleman was bariatric in size (overweight) it gave us some problems,” explained the watch commander.
One of SECAmb’s two bariatric units was deployed to the scene from Chichester.
The ambulance - designed to cope with patients who weigh up to 50st - has wider lifting equipment and specialist handling aids.
As crews waiting for the unit to arrive firefighters asked police to close the A29 and got to work removing the driver’s door.
Mr McKilligin said: “We needed to make sure that we could get full access to him so we could safely remove him.
“He was conscious throughout and coped very well with what was a very stressful situation.”
The bariatric unit joined SECAmb’s two cars and ambulance already at the scene.
Paramedics treated the driver before he was put onto a stretcher and taken to Royal Sussex County Hospital in Brighton.
A spokesperson for SECAmb said as well as a fractured ankle the man suffered from chest and abdominal pains.
Crews left the scene at around 8.30pm.
SECAmb’s two bariatric units cover Sussex, Surrey and Kent.
