From a press release:
Effective Jan. 1, 2018, Virginia state inspection stickers will no longer be affixed to the bottom center of a vehicle’s windshield. Due to new innovations in the automotive industry, the state inspection stickers will be placed in the bottom left corner of the windshield, when viewed from inside the vehicle. This change in location will also apply to the placement of any other authorized stickers. There have been no changes made to the size or appearance of the existing vehicle inspection sticker.
