Can I get a ticket for expired license tabs if it is always parked in my driveway and I never drive it?

My understanding is that if a vehicle is visible to a police officer from the street, the vehicle would be assumed to be used (unless the vehicle is obviously inoperable such as missing all tires. Having an inoperable vehicle on the driveway eventually leads to a land use code violation.) On the other hand, I see many vehicles with expired tabs being driven around. So, may be you will get lucky and no one notices your vehicle.

Incidentally, unless your car is new or expensive, the license tab fees likely are less than $100. The renewal notice that you should have received would have the licensing fees on the notice. You can check at this site for the amount of the fees: http://www.dol.wa.gov/vehicleregistration/renewtabs.html . You can cancel the transaction before your credit card is charged.
