People caught skate boarding or using in-line skates in parts of Yeovil risk a £500 fine after new byelaws were introduced for safety reasons.
The sport is banned from the busier shopping areas and car parks and only permitted elsewhere as long it does not cause annoyance or danger.
A council spokesman said skate parks had been built and there was no reason why the town centre should be used.
"Boarding in busy pedestrian areas is not acceptable," he said.
Tony Lock, Mayor of Yeovil, added: "We have to balance the need for shoppers to be able to visit the town centre in a safe manner with the potential dangers posed by these popular pastimes."
