Cab driver Brynley Potter, 50, was sentenced on Tuesday to five days in Winchester Prison after he accidentally drove his vehicle with the fog lights illuminating a clear stretch of road in Portsmouth, UK. The city of Portsmouth rarely experiences fog, but thick fog often envelops surrounding areas.

Potter happened to have dropped off a passenger at just such a foggy area -- a hospital on Portsdown Hill. On his return, a city police officer noticed Potter had forgotten to turn off his fog lights. The officer hit him with a £30 ticket (US $56) -- £5 more than the cab driver had made on the fare.

"I refused to pay it because I didn't think it was fair," Potter told the Portsmouth News. "Why didn't they just tell me to turn off the lights?"

A judge found that Potter had received one previous warning regarding the use of fog lights and convicted him for refusing to pay the fine. Potter spent two days in the prison with murderers and other violent criminals.
