Seven people, including an infant, were taken to hospital following a three-vehicle crash on the M5 in Somerset.
Emergency services were called to the northbound carriageway between the Burnham-on-Sea and Bridgwater junctions at 1235 BST on Saturday.
One person who was trapped in the wreckage was released by firefighters.
The accident comes less than 24 hours since a seven-car pile-up on the same stretch of motorway which caused tailbacks to the Taunton junction.
On that occasion two people were cut out of one of the vehicles and five people, including a child, taken to hospital.
The busy motorway was closed for 90 minutes while the accident was cleared.
