A single-occupancy vehicle (SOV) is a privately operated vehicle whose only occupant is the driver. The drivers of SOVs use their vehicles primarily for personal travel, daily commuting and for running errands; the types of vehicles include, but are not limited to, sport utility vehicles (SUVs), light-duty trucks, and any combination thereof, along with all the various van and car sizes, but would generally be taken to exclude human-powered vehicles such as bicycles. This term is used by transportation engineers and planners. SOVs contrast with high-occupancy vehicles (HOV), which have two or more occupants.[1][2][3] Keep in mind that SOV in this context refers to a status and usage, not the vehicle type.
