  • Page 14 8 Always avoid operating an ATV on any paved surfaces, including sidewalks, driveways, parking lots and streets. 8 Never operate an ATV on any public street, road or highway, even a dirt or gravel one. 8 Never operate an ATV without wearing an approved motorcycle helmet that fits properly. You should also wear eye protection (goggles or face shield), gloves, boots, long-sleeved shirt or jacket, and long pants.
  • Page 15 8 Never operate on excessively rough, slippery or loose terrain until you have learned and practiced the skills necessary to control the ATV on such terrain. Always be especially cautious on these kinds of terrain. 8 Always follow proper procedures for turning as described in this manual. Practice turning at low speeds before attempting to turn at faster speeds.
  • Page 16 8 Always use proper procedures if you stall or roll backwards when climbing a hill. To avoid stalling, maintain a steady speed when climbing a hill. If you stall or roll backwards, follow the special proce- dure for braking described in this manual. Dismount on the uphill side or to a side if pointed straight uphill.
