If an emissions sticker is going to expire within 90 days, what action must be taken?

When an emissions sticker is set to expire within 90 days, it is necessary for the vehicle to be reinspected for emissions compliance. This is a vital step to ensure that the vehicle continues to meet the state's environmental standards and regulations. Emissions stickers indicate that a vehicle has passed all necessary emissions tests, and allowing them to expire without re-inspection can lead to potential penalties for the vehicle owner and non-compliance with state laws. Reinspection ensures that the vehicle remains safe to operate and does not contribute to excessive pollution.

In this context, the other actions—like issuing a temporary safety sticker, waiting for the emissions sticker to expire, or notifying the customer to return later—do not address the immediate requirement for emissions compliance. Each of these options lacks the proactive approach needed to maintain proper vehicle registration and environmental responsibility. Only the requirement for re-inspection ensures that the vehicle remains compliant with state emissions regulations.
