Learn about the process for NC smog checks, whether your vehicle requires safety and emissions testing and how to find an emissions testing center near you by reviewing the information contained below.
North Carolina Emissions and Smog Check Requirements
North Carolina vehicle inspection guidelines are set by the state Division of Motor Vehicles, or DMV. The multiple-step safety and emissions inspection consists of the following procedures:
- Check headlights, accessory lights and directional signals.
- Test the braking systems, including the foot brake and parking brake.
- Check the steering and windshield wipers.
- On-Board Diagnostic (OBD) emissions test on vehicles manufactured since 1996.
- A tampering visual inspection to make sure emissions components are present and functional.
Vehicles manufactured in 1995 or earlier will not have an OBD emissions test because these vehicles were not equipped with this computerized system. However, these vehicles must still undergo the safety portion of the vehicle inspection if they meet the other qualifications and are less than 35 years old.
Safety and emissions testing in NC is only required for residents of the following 48 counties: Alamance, Brunswick, Buncombe, Burke, Cabarrus, Caldwell, Carteret, Catawba, Chatham, Cleveland, Craven, Cumberland, Davidson, Durham, Edgecombe, Forsyth, Franklin, Gaston, Granville, Guilford, Harnett, Haywood, Henderson, Iredell, Johnston, Lee, Lenoir, Lincoln, Mecklenburg, Moore, Nash, New Hanover, Onslow, Orange, Pitt, Randolph, Robeson, Rockingham, Rowan, Rutherford, Stanly, Stokes, Surry, Wake, Wayne, Wilkes, Wilson and Union.
In these counties, 1996 and newer gasoline-powered light-duty vehicles with a gross vehicle weight rating (GVWR) less than 8,501 pounds must obtain an annual emissions inspection as well as a safety/tamper inspection.
Smog Check Exemptions in North Carolina
Certain vehicles are exempt from emissions testing in NC, including vehicles registered in counties other than those listed above. Other vehicles exempt from smog testing are those manufactured in 1995 or before, diesel vehicles, heavy-duty vehicles with a GVWR over 8,501 pounds and vehicles powered by alternative fuels without gasoline. Although these vehicles are exempt from DMV emissions testing, they still must obtain an annual safety inspection. Motorcycles, recreational vehicles (RVs) and motor homes are exempt from emissions testing for vehicle registration purposes. Vehicles older than 35 years are not required to undergo any type of inspection in any NC county.
New motor vehicles that have never been titled before will receive a safety/tamper inspection for its first year of registration. During the second year of registration the full safety and emissions test will be required if the vehicle is registered in an emission county. Effective in 2015, vehicles within the three most recent model years that also have fewer than 70,000 miles may also qualify for an emission inspection exemption.
Out-of-State Emissions Testing in North Carolina
If your NC emissions inspection is due while you are out of the state, you can obtain a smog test where your car is located if that state's standards meet those set by the U.S. Environmental Protection Agency. If you cannot obtain an emissions test locally, contact the NC DMV Headquarters at (877) 421-0020 to receive guidance on your particular situation.
If you are out-of-state on active military service when your vehicle inspection is due, Senate Bill 509 from the General Assembly 2007 Session allows service members to waive the penalty for not obtaining the smog test within the four-month grace period following expiration. You must obtain a North Carolina safety and emissions inspection upon returning to the state. Contact your local NC DMV office to learn more about this waiver for active duty military personnel.
Emissions Waivers in North Carolina
Vehicles that fail the North Carolina emissions inspection but pass the safety tests may be eligible for a waiver if they meet certain requirements. Waiver-eligible vehicles must pass the visual inspection, but fail the OBD smog test on their first inspection attempt. The vehicle owner must then have the necessary repairs performed by a certified mechanic and obtain documents that prove the repairs cost $200 or more. If upon re-inspection, the vehicle once again passes the visual tests but fails the OBD emissions check, the driver may apply for a waiver. Before issuing the vehicle emissions testing waiver, a DMV agent must review the receipts and inspection reports provided by the owner.
Testing Fees in North Carolina
The state caps the maximum annual fee for NC vehicle inspections at $30 for emissions testing and $13.60 for safety tests. However, emissions testing stations may choose to charge less through the issuance of smog check coupons or other cost-reducing measures. Most smog check stations accept a range of payment methods, including cash, checks and major credit cards.
