According to traffic monitoring system Inrix, the collision took place on the M5 southbound at J25 A358 (Taunton). Inrix said: “Lane one (of three) is closed. Heavy traffic.”
It is unclear whether anyone was injured in the collision.
The lane has now reopened.
Despite the disruption, traffic now appears to be flowing smoothly.
This is already the second M5 collision in the Somerset area this morning.
The first crash, reported by Inrix, took place on the southbound carriageway of the motorway just before J24 A38 Taunton Road (Bridgwater South).
Heavy congestion built up on the M5 in the wake of the crash, which was reported just after 10am this morning.
The same road saw rush hour traffic on the day before Christmas Eve grind to a halt following a car fire.
Fire crews were called to the M5 northbound between junctions 19 and 20 near Clevedon at 8.18am on December 23.
They reportedly found a car “well alight”.
There were no reported injuries.
At the time, a spokesperson for National Highways said: “Following a car fire in lane one northbound at 08.19, the north and southbound carriageways were closed by police due to smoke.
“The vehicle remains on the hard shoulder with police and the fire service still in attendance.
“Lane one northbound will remain closed for another hour, with all other lanes now reopened.
“Once the vehicle has been removed, inspections of the road will take place to ascertain if resurfacing is required.”
