“Paramedics, police and fire crews were so quick to respond and were fantastic. They cut the roof off. Air ambulance landed in Marlborough School fields

“I believe the lady is OK, but in shock.

“Gentleman who lives on the road expressed how measures should be taken to stop speeding in the road and he will be raising this with the council with the photos he took.

“There is no evidence to suggest she was speeding but I think it just highlighted other concerns.”

Both crews from St Albans fire station were called at 11.34am and report that a casualty had to be cut out of vehicle.

There are road closures in place on Vesta Avenua and St Stephen’s Hill.

Recovery is being arranged for the vehicle.
