Overview: Giant racing monsters take to the track in a special Top Gear from the first British Truck Grand Prix. William Woollard meets the stars and the working truckers who unhitch their trailers to push five tons of highly-powered steel to the limit round the Donington Park circuit, while reporter Chris Goffey climbs into the cab in an attempt to fight his own way to the final. And between races there's a chance to see spectacular two-wheel stunts, a jet truck and Britain's fastest delivery service -the 170 mph Supervan.
