Types of Off-Highway Vehicles
All-Terrain Vehicles (ATVs): ATVs are “off-road, motorized vehicles having three or four low-pressure tires, a straddle seat for the operator, and handlebars for steering control.”
Recreational Off-Highway Vehicles (ROVs): ROVs are OHVs with “four or more wheels with low pressure tires; bench or bucket seating for two or more occupants; automotive-type controls for steering, throttle, and braking; rollover protective structures (ROPS); occupant restraint; and maximum speed capability greater than 30 mph.”
Utility Task Vehicles (UTVs): UTVs have the same design elements as ROVs, but UTVs have maximum speeds of 30 mph or less.
All of these vehicles carry risks of serious injury and death when not used properly or with the appropriate safety equipment and all of these vehicles could be made safer with a few common sense design changes.
