The other woman, in her 50s, sustained injuries that were not believed to be serious.

The driver of the Ford, a man in his 60s, was taken to Poole Hospital for treatment to injuries that were not believed to be serious.

Sergeant Rhys Griffiths, of the traffic unit, said: “We are carrying out a full investigation to establish the circumstances of this collision and I would urge any witnesses who have not already spoken to police to please contact us.

“I would also ask anyone who was driving in the area and has dashcam fitted to their vehicles to please check their footage for anything of relevance.

“Finally, I appreciate the closure of a main trunk road will have caused inconvenience for many, but this was absolutely necessary to allow the emergency services to respond to the incident, for the vehicles to be recovered and for the scene to be made safe. I would like to thank members of the public for their patience and understanding while the closures were in place.”
