Two people were trapped in their cars after a four-vehicle crash in Tesco car park in Copdock, near Ipswich.
Three fire crews from Ipswich East and Princes Street were sent to the incident just before 12.30pm.
They had to remove the roof and one door of one of the vehicles to free people from inside.
The incident had been brought under control soon after 1.20pm, and all crews had returned to their bases by 1.50pm.
