New Rhode Island Residents

Inspection Requirements & Exemptions
Safety AND emissions inspections are required every 2 years for:
- All gasoline-powered passenger vehicles.
- Vehicles 25 model years old and older will not receive failing status if they don't pass the emissions portion of the test.
- Light-duty vehicles 8,500 lbs. and under.
Newly- registered vehicles must inspection within 5 days of registration.
Other vehicle types require only one kind of test or have different inspection time frames; these vehicles include:
- Heavy-duty vehicles and trucks.
- Trailers and semi-trailers.
- Livestock trailers.
- Vehicles purchased from licensed dealers.
Visit the DMV's Inspection Requirements page for details about these vehicle types.

The following vehicles are exempt from safety and/or emissions testing:

- Exempt for 2 years from the purchase date OR until the vehicle reaches 24,000 miles (whichever happens first).
- Vehicles registered exclusively with Antique Plates.
- Electric vehicles:
- Exempt from emissions testing BUT NOT safety testing.
Completing a RI Vehicle Inspection
Bring your vehicle to any Rhode Island Emissions and Safety Testing certified inspection station UNLESS you operate a light-duty diesel vehicle weighing 8,500 lbs. or fewer. Light-duty diesel vehicles must be inspected at select inspection stations throughout the state.
A safety and emissions inspection costs $55; call ahead for information on required paperwork such as registration and insurance documentation or driver's license requirements.
Once your vehicle passes the safety and emissions inspection, you'll receive an inspection sticker valid until it's time for a new inspection; again, these time frames can vary by vehicle type.
Failed RI Vehicle Inspections
Regardless of which portion of the test your vehicle fails, you must have your vehicle repaired and retested. You can have your vehicle repaired at the facility of your choosing, though Rhode Island does provide a list of Certified Inspection Repair Technicians (CIRTs) from which to choose.
After having your vehicle repaired, you can have it retested for free if you bring it within 30 days to the same inspection facility that performed the initial inspection; if you bring it to another location, you'll have to pay the $55 inspection fee.
If you've made the necessary repairs and your vehicle still fails, you might be eligible for one of the following emissions test waivers:
Learn more about these waiver requirements at the failed inspection information page.
About RI Safety & Emissions Testing
