Three young men have been hurt, two potentially seriously after a single vehicle rollover RTC.
It happened on Gayhill Lane in Kings Norton just after midnight.
The first ambulance arrived seven minutes after a 999 call from a member of the public who had come across the crash.
A second ambulance, a paramedic officer and the MERIT trauma doctor and critical care paramedic were also sent to the scene.
A West Midlands Ambulance Service spokesman said: “On arrival, ambulance staff found a car that had suffered significant damage.
“A man of around 20 years was found in a field nearby. While ambulance staff assessed his condition, firefighters opened a gap in the hedge and fence so that he could be brought to the ambulance.
“The man was anaesthetised at the scene and immobilised before being taken on blue lights to the major trauma centre at Queen Elizabeth Hospital Birmingham with the doctor accompanying the crew.
“An 18-year-old man was also taken on blue lights to the same hospital with multiple bruising and lacerations after he was found beside a bush next to the car.
“A third man who was also 18 had self-extricated. He had suffered a nasty laceration but was otherwise uninjured. He was taken to the same hospital.”
