A woman has been anaesthetised at the scene of a serious RTC.
The crash happened on Shenley Lane in the Weoley area of Birmingham.
An ambulance was on scene within seven minutes and was backed up by a second ambulance, a paramedic officer and the MERIT trauma doctor and critical care paramedic.
A West Midlands Ambulance Service spokesman said: “On arrival, ambulance staff found a small blue car with substantial damage to the driver’s side and a Jaguar car with front nearside damage.
“The driver of the blue car, a 20-year-old woman, was initially unconscious. She was being helped by an off-duty GP and a police officer who was holding her neck still.
“Ambulance staff worked with firefighters to extricate the woman. After assessment, she was anaesthetised by the doctor and taken on blue lights to the major trauma centre at Queen Elizabeth Hospital Birmingham with a suspected head injury.
The 54-year-old man driving the Jaguar had managed to get out of the vehicle himself. He was complaining of muscular chest and right arm pain. After assessment, he chose not to go to hospital and was discharged at the scene.
