TRAFx OFF-HIGHWAY VEHICLE (OHV) COUNTER FAQs Is an OHV the same as an ATV or ORV?
Most government agencies classify all-terrain vehicles (ATVs) and off-road vehicles (ORVs) as off-highway vehicles (OHVs), so this is the term we use. We could have also called it an ATV counter or an ORV counter — the various terms are interchangeable. OHV generally implies motorized vehicles used for outdoor recreation.
