What is an Off-Highway Vehicle (OHV)?
Any motor vehicle operated off-highway is an OHV. A highway licensed vehicle is an OHV when operated off of the highway. Vehicles having Green and Red Stickers are OHVs. Some of the more common OHVs include all terrain vehicles (ATVs), dirt bikes, sand rails, recreation utility vehicles (RUVs), golf carts, snowmobiles, go carts, jeeps, and 4x4s. (1)
What is a side-by-side?
Yamaha Rhino and Polaris Rangers and RZRs are examples of off-highway motor vehicles commonly referred to as side-by-sides for their seating configuration, as opposed to an ATV with a seat that is straddled by the operator. These side-by-sides are also called utility vehicles (UTVs), recreational off-highway vehicles (ROVs) and recreational utility vehicles (RUVs) as well
as other names used by manufacturers and owners. Other states may define these vehicles as ATVs in their laws and regulations, but the California definition of an ATV includes "three or more low pressure tires, a seat designed to be straddled by the operator and handlebars for steering."
ATVs once had three wheels, but new ATVs sold today have four wheels. In California, Vehicle Code (CVC) 111 defines an ATV as fifty inches or less in width; nine hundred pounds or less, unladen; three or more low pressure tires; a single seat designed to be straddled by the operator, or a single seat designed to be straddled by the operator and a seat for no more than one passenger; and has handlebars for steering control.
