Two adults in their 40s and a teenage child have been killed a crash on the M5.
Avon and Somerset Police said a white BMW left the northbound carriageway of the M5 at about 21:00 BST on Friday, between J14 (Falfield) and Michaelwood services.
A second child has been taken to hospital after sustaining serious injuries in the crash, police said.
National Highways said “due to the severity of the incident and complexity of the vehicle recovery”, the M5 was likely to remain closed until about 16:00 BST.
