WHAT CAN HAPPEN All wheels turn at the same speed when the differential is locked, so it takes more effort to turn the ATV. The effort needed to turn increases with the riding speed. You may lose control and have an accident if you cannot make a sharp enough turn for the speed you are traveling. HOW TO AVOID THE HAZARD Always ride at a slow speed when the ATV is in four-wheel-drive differential gear lock, and allow extra time and distance for maneuvers.
