The Judge presiding over the trial of an organiser of a firework display near the scene of a crash on the M5 said he had "no previous reason to think it was a hazard."
7 people died in the pile up on the motorway in 2011. Geoffrey Counsell was accused of failing to ensure the safety of others when smoke from a fireworks display blew onto the road before the crash.
But Judge Justice Simon directed the jury to return a verdict of not guilty.
Fireworks contractor Geoffrey Counsell, 51, who was in charge of a display held on the night of a massive crash on the M5 in Somerset in which seven people died and 51 were injured.
He was cleared of breaching health and safety laws today by a jury at Bristol Crown Court on the direction of a judge.
