On the motorway, a moment's lapse of concentration can have devastating consequences and when a lorry is involved the results can be catastrophic. The Motorway Cops are called to an accident involving a 44 tonne lorry, causing traffic chaos and leaving three dead and many more injured.

PCs Griffiths and Toal are involved in a high-speed chase which takes them into Birmingham city centre, and PC Richard Elliot is called to a lorry park off the M6 where a gang has been disturbed while attempting to steal the load from the back of a lorry. Also, more than 20 motorway cops, a dog team and the West Midlands Police helicopter are involved in an operation to stop a gang involved in a cash-in-transit robbery.

At night, a lorry jack-knifes on an unlit section of the M6, and two cars have ploughed full-speed into the underside of its trailer. The roofs of both cars have been taken off in the impact, and one man is dead. But, miraculously, three others have survived. It's up to PCs Elliot, Bullard and Shail to find out if this was simply the hand of fate or if someone is to blame.

The Motorway Cops are after runaway drivers including a stolen high performance car with a determined thief at the wheel. The thief is so determined that he risks a head-on crash as he drives the wrong way down the motorway, leaving the cops to launch a city-wide search for him.

The Motorway Cops help stop a stolen lorry on the rampage in the city centre. Elsewhere it's guile which catches people who are economical with the truth.
