In order for the government to convict you of Reckless Driving by Speed the Commonwealth has to prove beyond a reasonable doubt that you were driving a motor vehicle.

Virginia Code section § 46.2-100 defines Motor Vehicle as: 

“‘Motor vehicle’ means every vehicle as defined in this section that is self-propelled or designed for self-propulsion except as otherwise provided in this title. Any structure designed, used, or maintained primarily to be loaded on or affixed to a motor vehicle to provide a mobile dwelling, sleeping place, office, or commercial space shall be considered a part of a motor vehicle. Except as otherwise provided, for the purposes of this title, any device herein defined as a bicycle, electric personal assistive mobility device, electric power-assisted bicycle, motorized skateboard or scooter, moped, or personal delivery device shall be deemed not to be a motor vehicle.”

According to the definition above, you can see that most things in Virginia would constitute as a “motor vehicle.” However, there are certain things that might NOT constitute as a motor vehicle; such as, bicycles (regardless of whether they are motorized) as well as motorized scooters, mopeds, skateboards, and personal delivery devices, none of which would constitute a motor vehicle.
