Motorists caught up in a car crash on the M5 in which 7 people died have told an inquest how they became disorientated driving through a "white curtain" of fog.
The crash in November 2011 involved 34 vehicles. It happened on the night a fireworks display was being held at Taunton Rugby Club.
The event organiser, Geoffrey Counsell, was cleared of breaching health and safety regulations last year. Today, a coroner heard conflicting reports about the cause of the low visibility.
Richard Lawrence reports.
