These Are The Most Common Reasons Cars Fail State Inspections

February 6, 2026

You pull in thinking it will be quick, then one small detail stops the sticker from happening today. Most failures are not dramatic. They're basic items that have been slowly slipping for months. If you know what commonly trips people up, you can fix it on your schedule instead of scrambling.


Most failures are preventable with a few smart checks.


Lights And Signals That Don't Work


Burned-out bulbs are a top reason cars get turned away, and drivers miss them because you can't see your own brake lights while driving. Turn signals that flash fast, reverse lights that are out, and license plate lights are easy to overlook. Moisture in a housing, a weak connection, or a bulb near the end of its life can all cause an intermittent failure.


Do a quick walk-around every couple of weeks, ideally with someone pressing the brake pedal while you watch. If you're solo, back up near a reflective surface at night and check the glow. Fixing a simple bulb early also keeps you from driving around with reduced visibility to others.


Tire Tread, Damage, And Pressure Problems


Tires can get flagged for low tread, uneven wear, sidewall bubbles, or damage near the shoulder. Even if the tread looks okay at a glance, worn edges can sneak up on you when alignment angles drift or suspension parts loosen. A tire that's been run underinflated can also wear the shoulders fast, and you may not feel it until it's obvious.


Before your appointment, look for nails near the sidewall, bulges, and cracks that look deeper than surface aging. A quick at-home inspection of tread and sidewalls can save you a wasted trip. If one tire is wearing much faster than the others, it usually means the vehicle needs attention beyond just tires. Regular maintenance, like rotations and pressure checks, makes this category far less surprising.


Brake Wear And Brake Warning Lights


Brakes get flagged for thin pads, severely worn rotors, fluid leaks, or warning lights that stay on. Pads can drop from okay to too thin quicker than you'd expect if you drive in heavy traffic or you've got a caliper that isn't releasing cleanly. A squeal or light grind is a strong hint you're already close to the limit.


Pay attention to pedal feel, too. If the pedal suddenly feels lower, harder, or takes more effort, get it checked before your visit. If a brake-related warning stays on, it usually won't pass until the fault is repaired and the light stays off. We also see cars turned away because ABS, brake, or stability lights are on, even when stopping feels normal.


Check Engine Light And Readiness Issues


A check engine light is a common failure, but even when the light turns off, the car may still not pass that day. After a battery disconnect or code clearing, the vehicle needs time and specific driving conditions to reset its monitors. Show up too soon and the system can report not ready, even though it drives fine.


Clearing codes right before your appointment often backfires for that reason. If the light came on recently, a quick scan can point you toward the cause and save a repeat trip. Keeping up with the factory schedule also helps prevent small issues that trigger recurring warning lights.


Windshield, Wipers, And Safety Glass Problems


Windshields can get flagged if a crack sits in the driver's view or if it's spreading in a way that affects visibility. A lot of drivers get used to a crack and stop noticing how it catches glare at night. Chips that were once small can also grow after temperature swings, so something that looked fine last month may not be fine today.


Wipers matter, too, because a torn blade or skipping sweep leaves streaks right where you need clarity. Make sure the washers spray properly and the blades wipe clean across the glass. If you can't see clearly in rain, it's a safety issue and an easy fix compared to bigger repairs.
