Avon and Somerset Police were called about a road traffic collision on the M5 Southbound between J24-25 at 8.10am this morning.
The cars were moved to the hard shoulder and the motorcyclist received attention at the scene “for what is believed to be a spinal injury” said police.
Two fire appliances from Bridgwater and a rescue tender from Taunton were mobilised to what fire crews confirmed as a “five vehicle RTC involving one HGV, three cars and one motorbike.”
Devon & Somerset Fire & Rescue Service confirmed two casualties and one motorcyclist were attended to by paramedics and the fire service and that both casualties were taken to hospital by road ambulance.
The driver of one of the vehicles was still in the car but not physically trapped and all vehicles were made safe.
The motorway was closed southbound between J24-25 and motorists were being urged to avoid the area and find alternative routes as it was likely to remain closed for some time.
At 09:53, police confirmed that one lane on the M5 Southbound was opened to release some of the traffic and the motorway would close again to enable a recovery vehicle which has arrived at the scene to help clear the carriageway.
At 10:41, police announced that lanes two and three had reopened but lane one remained closed whilst the vehicles were recovered.
At 12:04, Highways England confirmed that all lanes were open on the M5 Southbound between Junctions 24 and 25 and that traffic was flowing freely and delays were starting to ease.
