Skip The Detour
Every year, countless vehicles face an unexpected detour to the repair shop after failing inspection due to common, yet often overlooked issues. From brake lights that refuse to illuminate to windshields that obscure rather than reveal, these problems can sideline even the most reliable cars. It's time to discover the top reasons vehicles miss the mark and ensure yours isn't next.
1. Non-Functioning Brake Lights
Think of brake lights as your car's way of having a polite conversation with other drivers. When they go dark, that critical safety chat goes silent. This common inspection deal-breaker is particularly frustrating since a quick bulb swap is all it takes.
2. Excessive Brake Pad Or Rotor Wear
As any seasoned inspector will tell you, brake pad and rotor wear keep their red pens busy during safety checks. Those thin, rusty components are inspection-killers that compromise stopping power. Smart drivers listen for telltale squeals and schedule regular brake checks.
3. Severe Tire Tread Wear
That critical 2/32-inch tread depth threshold isn't just a finicky inspection standard—it's the razor's edge between safety and hazard on the road. Surprisingly, something as simple as regular pressure checks could prevent these worn tires from becoming a hazard.
4. Cracked Or Obstructed Windshield
A cracked windshield directly in your line of sight creates dangerous visual distortions that can mask oncoming hazards. Even minor obstructions, such as unauthorized window tint or aftermarket films, tamper with critical visibility. These safety risks automatically trigger inspection failure.

5. Broken Side Mirrors
Before rolling up to your station, take a good look at those trusty side mirrors. They're not just for checking out your vehicle's good side. State requirements vary, but functioning mirrors eliminate dangerous blind spots, making them a must-have.

6. Excessive Exhaust Emissions
Regular maintenance is your secret weapon against inspection day drama. This ensures that exhaust emissions remain well within legal limits. State environmental regulations require vehicles to pass strict testing, which often flags issues with catalytic converters or oxygen sensors.

7. Damaged Fuel System Components
Did you know that fuel system leaks have the power to give rise to a perfect storm of trouble? This is achieved by forming a triple threat tango of hazards. Such sneaky drips get busy juggling fire risks.
8. Inoperative Windshield Wipers Or Washer System
Failed wipers can fail your inspection faster than you can say "rain check," and that troublesome washer system needs to work, too. Thankfully, swapping those wiper blades is usually a quick and wallet-friendly fix, keeping you safely seeing through stormy weather.
9. Malfunctioning Check-Engine Light
A glowing check-engine light means something is wrong, since it flags emissions troubles or sensor issues in the OBD system. Meanwhile, the quick-fix crowd learns the hard way that resetting computer memory backfires, triggering an equally problematic "not ready " status.
10. Rusted Frame Or Structural Components
Winter's road salt brigade might keep highways clear, but it wages a sneaky war on vehicle frames underneath. As salt-triggered rust creeps through structural components, your car's once-solid foundation turns into automotive Swiss cheese. Its crashworthiness ratings plummet faster than winter temperatures.
11. Improperly Functioning Seat Belts
Defective or missing seatbelts pose a serious safety risk, undermining one of your car's most critical protective features. That's why thorough inspections verify the presence and proper function of every restraint—no frayed, broken, or missing belts are allowed.
12. Misaligned Headlights
Those pesky headlights could be your downfall. After all, misaligned or faulty beams frequently trigger failures. Beyond inspection woes, wonky headlights give rise to double trouble: poor visibility for you and dazzled oncoming drivers. Even factory-installed headlights can occasionally fail alignment tests.
13. Broken Or Non-Functioning Turn Signals
Being a courteous driver means letting others know your next move, which is exactly why those blinking turn signals are your car's way of waving hello. Modern dashboards have your back with rapid-flash warnings when a bulb decides to take an unscheduled break.
14. Missing License Plate Lights
Those sneaky license plate lights serve a serious purpose: helping law enforcement spot vehicles after dark. Regulations require that the license plate be clearly visible and readable from a specified distance, generally 20–50 meters. The lighting must be white or yellow in color.
15. Excessive Steering Play
That subtle play in your steering might feel like a minor wallet drain now, but watch those repair costs multiply from compromised handling and stability issues to accelerated tire wear from uneven contact, all leading to guaranteed trouble.
16. Defective Suspension Parts
Just like your favorite pair of shoes, suspension parts don't last forever. Those hardworking ball joints and struts naturally wear down over time. When they do, your once-smooth ride turns into a wobbly adventure until you bite the bullet and replace them.
17. Non-DOT-Approved Tires
When your tires don't match or lack DOT approval stamps, your vehicle's stability starts dancing to a dangerous tune. Inspectors scrutinize every tire for proper size, type, and those critical DOT markings because mismatched rubber can risk your vehicle and life.
18. Fluid Leaks
Nobody likes a drippy drama queen, but vehicle fluid leaks are serious business. They create slick road hazards that put everyone at risk. Those suspicious puddles under your ride are nature's way of flagging oil, transmission, or coolant issues.
19. Faulty Airbag Warning System
Remember when cars just had one lonely airbag? Now they're packed with a whole family of them—side, curtain, you name it. However, inspection stations won't take chances with these lifesaving cushions. A warning light or a missing airbag means your vehicle's staying put.
20. Missing Catalytic Converter
Environmental regulations demand effective emission control systems, making catalytic converters essential components that reduce harmful exhaust pollutants. While some vehicles require multiple converters for optimal performance, these vital devices face ongoing threats from thieves targeting their valuable precious metals.
