Exhaust Requirements

  • Your ATV must be equipped with a functioning muffler to prevent unusual or excessive noise. Exhaust systems cannot be louder than 96 decibels when measured on the "A" scale.
  • Your ATV must be equipped with a U.S. Forest Service–approved spark arrestor at all times, even during the winter.

Helmet Requirements

Each year a majority of the fatal ATV accidents in Wisconsin involve someone not wearing a helmet. Some of these victims could have survived had they been wearing a helmet. A helmet is the most important piece of equipment you can own. Helmets are generally required for all ATV riders under age 18; some exceptions exist.
