"On the outskirts of Gloucestershire lies one of the UK’s most unusual roads - a stretch of motorway where every crash, fire and pile-up is carefully staged. The M96 isn’t a real motorway at all, but a purpose-built training ground where fire crews, paramedics and police prepare for the worst that Britain’s roads can bring.

This documentary takes viewers behind the scenes of the UK Fire Service College, following trainees and veterans as they respond to realistic large-scale disasters designed to test teamwork, decision-making and courage under pressure. From chemical spills to multi-vehicle collisions, every scenario is a chance to learn before it happens for real.

M96: Motorway of Mayhem offers rare access to the hidden world of emergency training - showing how calm, skill and bravery are built long before they’re needed on Britain’s real roads."
