An elderly driver had to be cut out of her car by firefighters and was rushed to hospital after colliding with a lorry near a motorway slip road.
The woman’s Suzuki Wagon flipped onto its side on the A5 at the roundabout next to Junction 9 of the southbound M1 on Thursday afternoon.
The slip road leading to the roundabout, which is on the Redbourn side of the motorway, was closed from 3.45pm to 5.10pm.
An air ambulance was scrambled, but in the end the lady and a second person involved in the accident were taken to Watford General Hospital by land ambulance.
Hemel Hempstead Fire Station crew commander Steve Bradford said: “It was one car in collision with a lorry.
“They collided on the roundabout and the car landed up on its side with one person trapped inside. We cut the roof off and folded it back to get the driver of the car out.
“We worked very closely with the ambulance and air ambulance and it was a job well done by everybody.”
Two fire engines from Hemel Hempstead and one from Harpenden raced to the smash after a 999 call-out just after 3.40pm.
Mr Bradford said: “They closed the slip road, so there was a lot of traffic in the area.”
The driver was freed by 4.30pm.
