Motorways are the transport arteries on which Britain depends. Through bad weather, accidents and repairs, it's a constant battle to keep them moving. This series reveals the secret life of one the UK's busiest - the M6.

From the travellers who rely on it to the teams that work along it, the series features surprising stories and characters normally hidden from view. The repairmen who risk their lives as huge, fast and unpredictable vehicles thunder past, the irate local residents whose peace is disturbed by another set of night works and the police who mop up when things go wrong. The Motorway: Life In The Fast Lane provides a unique 360 degree insight into this vast and fascinating eco-system.
