What information must the inspector punch into the inspection sticker?

The inspection sticker must include the inspection month and year to indicate when the vehicle was last inspected. This information is crucial for monitoring the vehicle's compliance with safety and emission standards, as it helps ensure that inspections are conducted at the mandated intervals.

While other details such as the vehicle's VIN number, the name of the inspection station, and the inspector's certification number are important in the overall inspection process, the specific date of inspection—reflected in the month and year—is what is prominently noted on the sticker. This allows law enforcement officers, potential buyers, and others to quickly ascertain the status of the vehicle's compliance and whether it is due for another inspection.
