No-one was seriously hurt in the smash, with paramedics treating a number of walking wounded. At the peak of the accident, drivers were in queues for one hour and 30 minutes.

Southbound, queues were more than 18 miles back to junction 12 Cannock. Northbound, the tailbacks stretched around five miles to Junction 4A for the M42.

There was congestion on surrounding roads. The A38 Aston Expressway leading onto Spaghetti Junction in Birmingham and the A34 in Great Barr were jammed. Cars along the B4167

Hamstead Road in Great Barr were also queuing. In Walsall, queues on the Wolverhampton Road and Black Country Route stretched for two miles. There were tailbacks of around four miles on the Stafford Road.

Two lanes on the north and southbound carriageways re-opened at 8.45am.
