When to get an emissions inspection?
The emissions inspection is due once a year at the same time or before your annual safety inspection. If your vehicle is required to undergo an emissions inspection, the message "Emissions Inspection Required/Diesel Vehicles Exempt" will be printed on your vehicle registration card to remind you that an emissions inspection is required for your vehicle.

If your vehicle doesn’t pass?
If your vehicle doesn’t pass, you must make emissions-related repairs and have your vehicle re-inspected before your current safety inspection expires.Making these repairs will not only reduce emissions, but also may help you improve gas mileage and prolong the life of your vehicle. After necessary repairs are completed, the first re-inspection will be free, as long as it is done within 30 days at the same place that conducted the initial inspection. If your vehicle still doesn’t pass the inspection, and you can show that you have spent at least $150 on emissions-related repairs, you may be eligible for a one-year waiver. In some cases, you may have to spend more if a major repair, such as replacing a catalytic converter, is the only reasonable way to address the problem.You must obtain an emissions sticker or a waiver from a certified inspection station and pass a safety inspection before a safety inspection sticker can be affixed to your vehicle.

Exemptions and Exclusions…

A vehicle driven fewer than 5,000 miles during the 12-month period immediately preceding the inspection can qualify for an exemption sticker if you have owned the vehicle for one year or more. Just take your vehicle to an inspection station to verify your mileage and apply for an exemption sticker. Stations may charge a fee for an exemption. Also, if you have a new vehicle titled and registered for the first time and driven fewer than 5,000 miles, you can apply for an exemption sticker valid until the next inspection is due. Motorcycles are excluded from the emissions inspection program, as are vehicles registered as classics, antiques, collectibles, street rods or specially constructed.
