Trail Etiquette

Observing trail etiquette is important, particularly when trails are heavily used. Whenever possible, all snowmobiles shall keep to the right side of trails. Stay within the trail corridor and respect adjacent private and public land. When passing skiers, hikers, horseback riders, and other such trail users, operators shall reduce speed, yield right-of-way, and not pass until it can be accomplished with complete safety. Operators shall not accelerate until beyond 50 feed of such trail users.
