A driver has been airlifted to Southmead Hospital in Bristol with life-threatening injuries after a serious high speed collision in Westbury.

At around 10.30am this morning a white BMW collided with a stationary 7.5-tonne lorry parked on the West Wilts Trading Estate in the town.

The driver of the BMW, a local man in his 20s, was seriously injured in the smash.

He was treated at the scene by paramedics from Wiltshire Air Ambulance and then airlifted by the Great Western Air Ambulance to Southmead Hospital in Bristol.

There was no-one else travelling in the car and no-one in the lorry at the time of the collision.

The accident happened on Broadway North close to the junction with Engineer Road.

The road has been closed while police accident investigation takes place.

Three ambulances and five police cars attended the accident scene this morning.

The white BMW was travelling from Storridge Road and Victory Road onto Broadway North.

Police have appealed for witnesses with dash cam footage to come forward.

PC Peter Williamson, from Wiltshire Police's Collision Investigation Unit, said: "We are investigating how this vehicle ended up colliding with this parked truck on what is a straight stretch of road in broad daylight.

"We are asking anyone who may have seen a white BMW in the area just before this incident to come forward; perhaps there was something unusual about it or the way it was being driven.

"We'd also like anyone who may have dash-cam footage of this vehicle to contact us."
