If you just moved to the Wilmington area — or anywhere in North Carolina — your vehicle needs an annual state inspection. If you’re coming from a state without inspections (Florida, for example, which sends a lot of new residents our way), the whole concept may be new to you. If you’re coming from a state with inspections, NC’s process has its own rules and quirks.
At Derham’s Alignment & Auto Repair in Wilmington, we perform NC state inspections year-round and walk first-time customers through the process every week. Here’s everything you need to know before your first one — no surprises.
Two Parts: Safety + Emissions
The North Carolina annual inspection has two components, and whether you need both depends on your vehicle and where you live.
Safety Inspection — Required for Nearly Every Vehicle
Every registered vehicle in North Carolina must pass an annual safety inspection before its registration can be renewed. The inspector checks the mechanical systems that keep the vehicle safe on the road — brakes, tires, lights, steering, exhaust, windshield, and more. This applies to brand new vehicles and old trucks alike. Vehicles more than 30 model years old are not required to be inspected.
Emissions Inspection — Required in Certain Counties
New Hanover County — which includes Wilmington, Wrightsville Beach, Carolina Beach, and all the surrounding communities — is currently one of the counties where an OBD emissions inspection is required alongside the safety inspection.
Not every vehicle needs the emissions portion. Exempt from emissions but still needing the safety inspection: diesels, electric vehicles, motorcycles and RVs, vehicles rated over 8,500 lbs GVWR, vehicles with a model year more than 20 years old, and vehicles within their three most recent model years with fewer than 70,000 miles on the odometer. That 20-year threshold moves forward every year, so a vehicle that needed emissions testing last year may not need it this year.
The emissions test is an OBD-II scan — the inspector plugs into your vehicle’s diagnostic port and reads the engine computer. If any emissions-related diagnostic trouble codes are stored or the check engine light is on, the vehicle fails the emissions portion. This is why we always tell customers: if your check engine light is on, get it diagnosed before your inspection, not during it. Our check engine light diagnostic service identifies the issue so you can fix it and pass.
What the Inspector Checks — Item by Item
Knowing exactly what’s inspected eliminates the anxiety. Here’s the checklist:
Tires
Minimum tread depth of 2/32 of an inch across the entire tread surface. The inspector checks for uneven wear, bulges, exposed cords, dry rot, and cracks. Tires with bald spots or visible belt material fail immediately. If you’ve noticed uneven tire wear, address it before inspection — it often indicates an alignment or suspension issue that should be fixed regardless.
Brakes
Functional brake pads, rotors, and drums with sufficient material remaining. The parking brake must hold the vehicle on a grade. Brake lines are checked for leaks, corrosion, and damage. Brake lights must illuminate when the pedal is pressed. Near the coast, salt air corrodes brake lines and hardware faster than it would inland — on an older vehicle, corroded brake lines are a common inspection failure.
Lights and Signals
Every exterior light must function: headlights (high and low beam), tail lights, brake lights, turn signals (front, rear, and side), reverse lights, and license plate light. Bulbs must emit the legally correct color — no blue headlight bulbs, no red front turn signals. A single burned-out bulb is an inspection failure, and it’s also one of the cheapest things on this list to fix.
Exhaust System
The entire exhaust from the manifold to the tailpipe is inspected for leaks, holes, loose connections, and structural damage. Any leak that allows exhaust gas to escape before the tailpipe is a failure — this includes the catalytic converter, which must be present and intact. Exhaust components corrode from salt air and road moisture. Pipes and mufflers that look solid from above may be rusted through on the underside.
Steering and Suspension
The inspector checks for excessive play in the steering wheel, worn ball joints and tie rod ends, leaking shocks or struts, and any suspension component that’s visibly damaged, disconnected, or excessively worn. A ball joint with play or a tie rod end that’s loose will fail, because these are safety-critical components — a complete failure means loss of steering. If you’re already hearing clunks or squeaks from the suspension, get it looked at before your inspection date.
Windshield and Wipers
Cracks that impair the driver’s field of vision fail. Small chips outside the primary viewing area typically pass. Wiper blades must function and make contact with the windshield — torn, missing, or non-functional wipers fail.
Window Tint
North Carolina law requires at least 35% visible light transmission on most windows. Worth knowing: after-factory window tint is no longer part of the safety inspection itself — but the law still applies on the road, and an officer can still cite you for tint that’s too dark. If you moved from a state with more permissive tint rules, your vehicle may carry tint that was legal where you came from and isn’t here.
Horn
Must be audible from a distance. A weak or non-functional horn fails.
OBD Emissions Scan
Where the emissions portion applies, the inspector connects to the diagnostic port and reads the engine computer. Three things cause a failure: a stored emissions-related diagnostic trouble code, the check engine light being on, or incomplete readiness monitors — meaning the computer’s self-test cycles haven’t finished. That last one catches a lot of people. If you recently had a repair that required clearing the check engine light, the vehicle needs roughly 50 to 200 miles of mixed driving before the monitors are ready. Don’t clear a code and drive straight to inspection.
What Happens If You Fail
Failing isn’t the end of the world — it’s common, especially for vehicles that haven’t been maintained recently. Here’s how it works:
You get a report listing every failure item. The inspector documents exactly what failed and why.
You have 60 days to make repairs and return for free re-inspection. As long as you return to the same station within 60 days, there’s no additional inspection fee. After 60 days, you pay the full inspection fee again.
The re-inspection only checks the items that failed. If your brakes passed but your lights failed, only the lights are rechecked.
Emissions waiver. If a vehicle fails the emissions portion and a qualifying spend on emissions-related repairs at a licensed shop still won’t bring it into compliance, it may qualify for a waiver that allows registration. This applies only to the emissions portion — there’s no waiver for safety failures. We can tell you whether your situation is likely to qualify.
How to Pass the First Time
The best approach is a pre-inspection check. At Derham’s, we offer this as part of any visit — during an oil change or any other service, we can run through the inspection checklist informally and flag anything that would cause a failure. This lets you fix issues on your terms and schedule rather than discovering them during the official inspection.
Here’s a quick self-check you can do before your appointment:
Walk around the vehicle — Check every exterior light (have someone press the brake pedal while you check brake lights). Replace any burned-out bulbs.
Check tire tread — Insert a penny into the tread with Lincoln’s head facing down. If you can see the top of Lincoln’s head, the tread is below 2/32″ and the tire will fail.
Check the dashboard — If the check engine light is on, get it diagnosed and repaired before inspection. Any stored code with the light on is an automatic emissions failure.
Test the wipers and horn — Turn them on and verify they work.
Listen to your brakes — Squealing or grinding means the pads are worn and may not pass.
New to Wilmington? What You Need to Register
New North Carolina residents need a passing NC inspection before the vehicle can be registered with the NCDMV. You’ll also need a valid NC driver’s licence, the out-of-state title, and proof of liability insurance from an NC-licensed insurer. Many new residents don’t realise the inspection has to happen before registration — so get the inspection first, then take the paperwork to the DMV. Check the current NCDMV deadlines for registering a vehicle and obtaining a licence once you establish residency, since those are set by the state and do change.
Frequently Asked Questions
What does the NC vehicle inspection check?
The North Carolina inspection has two parts. The safety inspection checks tires, brakes, lights, signals, exhaust system, steering, suspension, windshield, wipers and horn. Where an emissions inspection is also required, the OBD-II computer is scanned for stored diagnostic codes, and the check engine light must be off with all readiness monitors complete.
Which vehicles are exempt from the NC emissions inspection?
Vehicles exempt from the emissions portion but still needing the annual safety inspection include diesels, electric vehicles, motorcycles and RVs, vehicles rated over 8,500 lbs GVWR, vehicles with a model year more than 20 years old, and vehicles within their three most recent model years with fewer than 70,000 miles. The 20-year threshold moves forward each year, and North Carolina’s emissions program is currently under federal review, so it is worth calling to check what applies to your vehicle.
What happens if my vehicle fails NC inspection?
You receive a report listing every failure item. You have 60 days to make repairs and return to the same station for a free re-inspection that only rechecks the items that failed. After 60 days the full inspection fee applies again. If a vehicle fails only the emissions portion and a minimum spend on emissions-related repairs still will not bring it into compliance, it may qualify for an emissions waiver.
Will a check engine light cause me to fail NC inspection?
Yes, where an emissions inspection applies. An illuminated check engine light is an automatic failure on the emissions portion regardless of the code or its severity. After any repair that clears the light, the readiness monitors must complete their self-test cycles, which takes roughly 50 to 200 miles of mixed driving. Do not clear the light and drive straight to inspection.
Do I need an NC inspection before registering my vehicle as a new resident?
Yes. New North Carolina residents need a passing vehicle inspection before the vehicle can be registered with the NCDMV. Get the inspection done first, then take the inspection result along with your out-of-state title and proof of North Carolina insurance to the DMV to complete registration. Check current NCDMV deadlines for registering a vehicle and obtaining a licence after you establish residency, as those are set by the state rather than by the inspection station.
