"The lorry driver was injured and 190 pigs were trapped in the vehicle. A vet came to the scene as soon as possible. They were consulted to ensure the animals' welfare at all times. The lorry driver was freed from the cab and taken to hospital at about 1am with injuries which are not believed life-threatening or life-changing," said the statement from the Avon and Somerset Constabulary.
"The M4 road was closed with a rolling roadblock while the lorry was righted, using specialist lifting equipment, at 4am. The damaged vehicle was then moved off the motorway so that the livestock could be safely released, treated and transferred to another transporter.
