We totally understand the concern—let’s see if you need to be worried.
Generally, most states don’t consider private parking lots “public roads,” so you’re relatively safe from getting ticketed for a driving infraction. Learning to drive in an empty lot is commonplace and, honestly, not a huge cause for worry.
But don’t take that advice and run with it. While something innocent like learning to drive a car isn’t too worrisome, engaging in illegal activities (like drinking in your car while parked or spinning some donuts)—even in a private parking lot—could have law enforcement questioning you and issuing a ticket or citation.
