Four people were taken to Dorset County Hospital after a two-vehicle collision near Grimstone.
One vehicle hit a lamppost which fell across the road after the crash on the A37.
At around 5pm on Sunday February 10, emergency services were called to the incident after a collision left people with minor injuries and smoke coming out of one of the vehicles.
A red Ford transit van and a silver Kia collided, with a female suffering from chest injuries, along with a 24-year-old man suffering bruising from his seat-belt.
Two children were also taken to hospital with minor injuries, while the local authority spent some time clearing a large quantity of vehicle fluid from the road surface.
Dorset Police were able to re-open the road at just before 7:30pm.
