Gethin finds out why lorries are among the biggest killers on our roads. He discovers that at some point two thirds of lorry drivers have reported feeling drowsy whilst driving and that nearly 20% have fallen asleep at the wheel. Gethin gets the chance to have a go in a lorry simulator after having just four hours sleep and finds that he soon learns that his driving is more dangerous than if he had been drunk.
