What Is Checked During a Vehicle Safety Inspection?

If you are due for your annual vehicle safety inspection, you may be thinking about your car and trying to decide if it has any issues that will prevent it from passing. Put your mind at ease with this vehicle safety inspection checklist from the local mechanics at Chapel Hill Tire.

Safety Inspection Check 1: Headlights

Properly functioning headlights are necessary for maintaining visibility at night and during inclement weather, as well as helping other drivers see you. Both of your headlights must be functioning and effective to help you stay safe and pass your inspection. Common issues include burnt-out bulbs, dim headlights, discolored headlight lenses, and cracked headlights lenses. These can often be repaired with headlight restoration services or replacement bulbs.

Safety Inspection Check 2: Tires

Over time, tire tread becomes worn and loses its ability to provide necessary traction on the road. This can result in handling and braking troubles, which are heightened during inclement weather. Tire health is necessary for passing both safety and emissions inspections. Keep an eye on your wear indicator bars or manually inspect your tire tread to ensure that it is at least 2/32 of an inch. Beyond just the tread depth, you can fail your safety inspection if your tires have any structural issues, including cuts that expose the cords, visible bumps, knots, or bulges. If any of these issues are present, you will need new tires to pass your inspection.

Safety Inspection Check 3: Turn Signals

Your turn signals (sometimes referred to as directional signals or indicators during inspections) are necessary for communicating your upcoming actions with other drivers on the road. Your turn signals must be fully functional and intact to pass your safety inspection. This inspection process checks the turn signal lights on the front and back of your vehicle. Common issues that lead to failure include burnt-out or dim bulbs, which are easily restored with bulb replacements

Safety Inspection Check 4: Brakes

The ability to properly slow and stop your vehicle is key to staying safe on the road. Both your foot brake and your parking brake are checked during an NC safety inspection, and they both need to work properly for you to pass. One of the most common brake problems that can cause you to fail your inspection is worn brake pads. This issue can easily be repaired with proper brake service.  

Safety Inspection Check 5: Exhaust System

While NC emissions inspections are relatively new, exhaust system checks have been around for years as a part of the annual safety inspection. This safety inspection step checks for removed, broken, tampered, or disconnected exhaust system parts and emissions control devices. Depending on your vehicle, this can include your catalytic converter, muffler, exhaust pipe, air pump system, EGR valve, PCV valve, oxygen sensor, and others. 

It used to be common for drivers tamper with these devices in an attempt to improve vehicle speed and performance. This practice has become much less popular over the years, so this check will likely only cause you to fail your safety inspection if an element of your exhaust system is failing. However, if you do choose to tamper with your emissions control devices, it could earn you a $250 fine in addition to a safety inspection failure. 

Safety Inspection Check 6: Brake Lights and Other Accessory Lighting

Listed as “accessory lighting” by the DMV, this component of your safety inspection includes checking your brake lights, taillights, license plate lights, reverse lights, and any other safety lights that may need servicing. Much likely your headlights and turn signals, the most common issue here is dim or burnt-out bulbs, which can be fixed with simple bulb replacements

Safety Inspection Check 7: Windshield Wipers

To help with visibility during inclement weather, your windshield wipers need to be working properly. The blades also need to be intact and functional without any noticeable damage in order to pass your inspection. The most common issue here is broken windshield wiper blades, which can be quickly and affordably replaced.  

Safety Inspection Check 8: Windshield Glass

In some (but not all) cases, a cracked windshield can lead to a failed inspection in North Carolina. This is often the case if the cracked windshield obstructs the driver’s vision. It may also cause a failed inspection if the crack impacts the proper functioning of any other vehicle safety device, such as the windshield wipers or rearview mirror mounting.

Safety Inspection Check 9: Rearview Mirrors

North Carolina safety inspections check both your rearview mirror and side mirrors. These mirrors must be properly in place, mounted securely, effective, easy to clean (no sharp cracks), and simple to adjust. 

Safety Inspection Check 10: Horn

To ensure that you can communicate with other drivers on the road, your horn is checked during your annual safety inspections. It must be able to be heard 200 feet ahead, and it cannot have any harsh or unusually loud sounds. The horn must also be securely mounted and safely wired. 

Safety Inspection Check 11: Steering System

As you might have guessed, proper steering is essential to vehicle safety. One of the first checks here involves “free play” with your steering wheel, which is the term used to describe any extra motion needed from your steering wheel before it begins to turn your wheels. A safe steering wheel does not exceed 3-4 inches of free play (depending on the size of your wheel). Your mechanic will also check your power steering system for signs of damage. This can include power steering fluid leaks, loose/broken springs, and a loose/broken belt. 

Safety Inspection Check 12: Window Tints

If you have had your windows tinted, they may need to be inspected to ensure that they meet the NC state guidelines. This only applies to after-factory window tinting. An expert will use a photometer to ensure that the tint has a light transmittance of more than 32% and that the light reflectance is not 20% or less. They will also ensure that the tint is properly placed and colored. Any professional tinting your windows should follow state guidelines, so this is unlikely to cause you to fail your inspection.

Motorcycle Safety Inspection

The NC safety inspection guidelines are roughly the same for all motor vehicles, including motorcycles. However, there are some adjustments made for motorcycle inspections. For example, instead of requiring two properly-functioning headlights, motorcycle inspections only require one. 

What Happens if I Fail my Vehicle Inspection?

Unfortunately, you cannot renew your NC registration with a failed safety inspection. Instead, the DMV will block your registration application until the safety inspection is passed. Thankfully, these inspections are completed by mechanics, who happen to know a thing or two about safety repairs. You can have any safety issues serviced to ensure that you pass your inspection.

Unlike an emissions inspection, you cannot file a waiver or become exempt from passing your safety inspection. One exception does apply to NC motor vehicles: antique vehicles (35 years or older) are not required to pass a safety inspection for vehicle registration.
