Gary Saunders, a company director, was using a hands-free phone when he burst out laughing at a joke told by his brother-in-law, who he was talking to.

A few moments later he noticed a traffic officer flashing his lights at him and gesticulating at him to stop his Renault. When Mr Saunders got out of his car, the policeman told him: “Laughing while driving a car can be an offence.”

The officer spent half an hour questioning his suspect before reluctantly allowing him to carry on his way. However, he took another hour-and-a-half of Mr Saunders’ time by ordering him to produce his licence and other documents at a police station.

Mr Saunders, the managing director of Spontex Workwear, of Liverpool, said the delay meant that he missed an important appointment. “I couldn’t believe it when he told me I’d been pulled over for laughing,” he said.
