The Motorway: Season 4, Episode 1

Episode 1

In the first episode, the motorway patrollers deal with a freak accident and a family in shock when a lorry's wheel comes off on the motorway and destroys their car.

Heavy rain sees floods, blocked drains and a high-speed aquaplaning disaster on the M42

A pedestrian puts lives in danger sprinting across eight lanes of the M6 at night and then assaults a patroller attempting to stop him.

And a car must be stopped from travelling on the M66 with a king size mattress tied to the roof, which threatens to fly off, causing disaster.
