Three people were taken to a major trauma centre after the car they were travelling in left the road and ended up in a ditch in Southam on Saturday.
The incident happened in Deppers Bridge at about 7.30pm.
Three ambulances, a paramedic area support officer, a community paramedic and a senior paramedic officer attended the scene.
A West Midlands Ambulance Service spokeswoman said: “The car had left the road and hit trees before rolling over and coming to rest in a ditch in a field.
“A 24-year-old man suffered a suspected head injury and lacerations in the collision. An 18-year-old girl was found with chest and suspected head injuries. A 22-year-old woman suffered a hip injury and a nasty fractured arm.
“The location and positioning of the car made it a difficult case for ambulance staff and fire fighter to treat the patients. Whilst ambulance staff worked to stabilise the patients’ conditions, the fire service carefully extricated them from the car. The 22-year-old woman was the last person to be released from the wreckage after around 45 minutes.
“All three patients were immobilised and administered pain relief before being taken by land ambulance on blue lights to University Hospital Coventry and Warwickshire for further emergency treatment.”
