What practice is strictly prohibited regarding inspection stickers?

The practice of loaning, making fake stickers, and displaying stolen stickers on a vehicle is strictly prohibited as they all undermine the integrity of the vehicle inspection system.

Loaning stickers to others can lead to misuse, where someone else uses the sticker on a vehicle that hasn’t actually undergone the required inspection. This jeopardizes safety and compliance with regulations.

Making fake stickers directly violates laws surrounding vehicle safety inspections. It can lead to significant consequences, as it falsely represents a vehicle's inspection status, potentially allowing unsafe vehicles to be on the road.

Displaying stolen stickers is not just illegal; it contributes to fraud and undermines the trust in the inspection process. Stolen stickers could be in the hands of individuals who do not care for vehicle safety or compliance.

Because all of these practices seriously compromise the vehicle inspection process, the choice that encompasses them collectively is the most accurate response. Therefore, all mentioned practices are prohibited, emphasizing the importance of lawful and proper vehicle inspections to ensure public safety.
