The motorway cops attempt to crack down on truckers who fail to pay attention to the road ahead. Many truckers are literally above the law, as the lorries are so high up that the cops in their patrol cars cannot see what the drivers are up to. But the police have a solution, using their own HGV to see what the truckers get up to when they are driving on the motorway.

PC Angus Nairn also leads the assault on truckers who pull tricks to stay on the road far longer than they should do. He teams up with VOSA traffic examiners in an operation to check them out, and they find some very disturbing problems.

As night falls, PCs Jess Rojek and Gary Williams race to an accident involving a lorry and two cars in an unlit section of the carriageway but, more disturbingly, they find that the driver of another car who stopped to help has herself been hit by a car as she tried to give assistance to the injured.
