If this was an exception you might laugh about it because it is too bizarre but it isn’t.
When Gary Sanders was pulled over by police he was sure he had done nothing wrong.
The company director was obeying the speed limit and not driving dangerously.
But to his astonishment he was told he had been stopped for excessive laughing.
Mr Sanders had been talking on a hands-free kit and was chuckling at what his friend had said.
But the officer who ordered him to stop at the exit to the Mersey Tunnel told him: ‘Laughing while driving a car can be an offence.’
If that had been the end of the matter then Mr Sanders, 47, would probably have laughed the whole thing off.
But he subjected him to a 35-minute grilling, with questions about everything from his ethnic group to details of distinguishing scars on his body.
And despite not being charged with an offence, he still had to waste a further 90 minutes of his time producing his driving licence and other documents at a police station.
Due to the delay Mr Sanders, the managing director of Liverpool-based Spontex Workwear, missed an important business appointment.
He said: ‘I couldn’t believe it when he told me I’d been pulled over for for laughing. I was driving very safely in the Birkenhead Tunnel and took a call from a friend on my hand-free phone.
