South of York, an aggressive motorcyclist squares up to a lone officer next to a busy road and tries to shift the blame on to the police for poor driving when one of his group is stopped for riding without tax and a tiny registration plate. A 70-year-old motorcyclist crashes down a steep 15ft embankment, but is spared serious injury as a clever gadget on his back comes to his rescue.

In North Yorkshire, more than a thousand drink-drivers are arrested every year meaning police are always looking out for suspicious cars and drivers taking their chances. Near Wetherby, a pursuit of a suspected drug driver reaches speeds of 130 mph before it ends with a head-on smash with a police car, while police receive reports that a driver has crashed his car down an embankment into a holiday home near Scarborough and fled the scene. Suspicions run high when a driver collides with a motorbike and then downs pints of beer in his local pub straight after the accident.
