AUGUSTA — Roller-skiers in Maine will have to follow the same rules of the road as bicyclists to protect their safety.

Gov. John Baldacci last week signed a bill sponsored by Rep. Michael Carey. The Lewiston Democrat’s sister, Eileen, is vice president at the Maine Winter Sports Center in Caribou, where a roller-skier was killed last year during training.

The new law will establish safety rules concerning the warm weather ski-training activity. For example, it says roller-skiers must travel with the flow of traffic and bars roller skis from divided highways.

The law, which will take effect three months after this legislative session ends, also says that roller skiers under 16 years old must wear helmets.
