What document indicates a vehicle has passed inspection?

An inspection sticker serves as official verification that a vehicle has undergone and passed the required safety and emissions inspections mandated by the state. This sticker is typically placed on the windshield of the vehicle and includes vital information such as the inspection date, the expiration date, and sometimes the facility where the inspection was conducted. It acts as a visible indicator to law enforcement and the public that the vehicle is compliant with state regulations for safety and emissions standards.

The other options, while important in their own contexts, do not serve the specific purpose of confirming an inspection status. A vehicle registration document provides information about ownership but does not indicate inspection compliance. A service history record details the maintenance performed on the vehicle but doesn't reflect its inspection status. A maintenance log tracks repairs and services but similarly does not provide information about the vehicle's inspection results. Thus, the inspection sticker is the definitive document that shows a vehicle has successfully passed its inspection.
