Series 5

Being a motorway cop means having to listen to every excuse in the book: sometimes they're ridiculous and unbelievable, while other times it's down to the skill and experience of the cops to work out fact from fiction.

Officers from West Yorkshire attend a serious head-on crash in Bradford.

Sometimes being in the right place at the right time can lead to some surprising results.

The West Yorkshire motorway police are not easily surprised or shocked by what they come across on Britain's busiest roads, but when a drunk student in Leeds flags down PCs Dale Anderson and Mick McQuade asking for a lift to France, the two cops quickly realise they have an unusual problem on their hands.

The Motorway Cops are called to the scene of a head-on collision on the motorway near Birmingham city centre. A woman has died and officers have to clear the road and try to discover the cause of the accident.

Every year, more than 50 tonnes of heroin and cocaine are sold in Britain, but in the north of England a team of specialist roads crime officers are striking back at the multi-million pound business of moving illegal drugs around the country.

A jack-knifed lorry causes a tailback on the A1 motorway leading to an accident between two lorries, leaving a man dead and forcing the motorway cops to shut the road while they investigate.
