Riding an ATV can be dangerous. To ensure your safety proper protective gear should always be worn. Remember to always wear a helmet, eye protection and protective clothing. Never ride on paved surfaces or public roads. Never carry passengers unless the ATV is specifically engineered to accommodate them.

Many ATV’s are recommended only for highly experienced riders 16 years and older. Please make sure that you are riding an ATV that is age appropriate. Riders younger than 16 years of age should always be supervised by an adult. We recommend that all ATV riders take an approved ATV training course and read their vehicle owner's manual thoroughly. When riding your ATV always stay on established trails in approved areas. Keep your riding areas clean and respect the rights of others. Always obtain permission before riding on private lands, and obey all the laws and regulations governing your riding areas. Warning: The Polaris RANGER® and RZR® are not intended for on-road use.
