What must be displayed on a vehicle after it passes a safety inspection?

When a vehicle passes a safety inspection, it is required to display a Certificate of Safety Decal. This decal serves as proof that the vehicle has met the necessary safety standards and has undergone an official inspection process. The visibility of this decal on the vehicle informs law enforcement and other authorities that the vehicle is compliant with safety regulations, helping to ensure road safety.

The inspection certificate is typically issued but may not be displayed on the vehicle itself; rather, it is kept on file or with the vehicle owner as documentation. The certification number could refer to the specific inspection process but is not something that is displayed on the vehicle like a decal. The registration tag pertains to vehicle registration and is separate from safety inspections, which focus specifically on vehicle roadworthiness.
