A man has been airlifted to hospital following a crash involving three cars.
It happened on the A37 near to the clay pigeon shooting range just before 1am this morning, involving a red Ford Focus, a silver Peugeot 207 and a pink Kia Picanto.
The driver of the Kia Picanto, a 69-year-old man from the Yeovil area, was flown by air ambulance to Southampton Hospital with serious injuries, which are not now believed to be life-threatening.
The Peugeot driver, a 30-year-old man from the Dorchester area, was taken to Dorset County Hospital for treatment to minor injuries.
The driver of the Ford Focus, a 54-year-old man from Portland, and a female passenger were treated by the ambulance service at the scene.
The road was closed at the Batcombe junction and the Chalmington junction. It has since re-opened.
