Patrollers Chris and Woody work 12 of the busiest motorways in Britain, including the M6. They race to the rescue of a young woman who swerved to avoid a tyre in the middle of the road, but crashed into a concrete barrier. She's now trapped in the middle of six lanes of high-speed traffic. All goes to plan until drivers start to ignore the emergency closed lane signs, putting the patrollers' lives in danger. In Lancashire, Dave and Chris come to the rescue of a school-run mum and her three young children when their car is hit and shoved sideways down the motorway by a 40-tonne truck. Patrollers Lewis and Nick deal with a series of breakdowns causing chaos on the M1. There's never a good excuse for running out of fuel on the motorway, but it's a dangerous and all too common problem for the patrollers. Unfortunately, there's worse to come, as Nick and Lewis find an abandoned lorry on the side of the M1. Chris and Woody must fight their way through traffic to reach a serious crash on the M6. And a £17 million roadworks project near Sheffield hits a bump in the road.
