A man suffered multiple fractures and a serious head injury after a crash on the A43 near Kettering.
Emergency services were called to the incident involving two cars just before 7.15am yesterday (Sunday).
Magpas doctor Dave Leverton and paramedic Simon Standen arrived at the scene in their rapid response car and assessed the 30-year-old man.
He had sustained multiple fractures and a head injury.
The man was sedated and anaesthetised at the scene before the team accompanied him by land ambulance to University Hospital Coventry.
The patient was in a serious but stable condition on arrival.
Four occupants of the other vehicle sustained minor injuries.
A police spokesman said: “A man sustained a serious head injury during a collision on the A43 near to the Hardwick turn, early on Sunday morning.
“The 30-year-old was driving a silver Renault Scenic on the northbound carriageway when it was in collision with a black Ford Galaxy travelling in the opposite direction.
“The Renault driver was taken to University Hospital Coventry with a serious head injury while the 71-year-old man driving the Ford was taken to Northampton General Hospital with minor injuries.”
