If your car is towed (i.e. no hangtag, expired inspection sticker, expired license plate registration, parked in fire lane, etc), call Dominion Towing at 703-339-2400. They have several storage lots to which your car can be brought.
Basic rates as of 2018 for an automobile are (1) $135.00 for basic towing; (2) $50.00 per day or any portion of a day; (3) $25.00 if towed between 7 pm and 8 am; (4) $25.00 if towed during a weekend; and (5) $25.00 if towed on a holiday.
Dominion Towing (open 24/7/365) does not accept personal checks. Payment in cash or Visa/Mastercard credit card is accepted.
If your car was parked on Americana Drive and was towed at the request of the Fairfax County Police Department (i.e. due to expired inspection/registration stickers, less than 10 feet from a fire hydrant, accidented or otherwise unserviceable etc.), it's best to call the Police Department at 703-691-2131. The police may have called a different towing service, not Dominion Towing.
