In 1993, Maine's legislature ordered the sticker placed on the windshield's left side or in the center behind the rear-view mirror, notes the Office of the Revisor of Statutes.
As of 2015, Texas does not have an inspection sticker, states the Texas Department of Motor Vehicles. Inspections are required to register a vehicle, and the registration sticker is placed on the windshield's left side.
