If you’re buying, selling, or registering a vehicle in Maryland, there’s a good chance you’ll need to pass the Maryland State Inspection first. This thorough, one-time inspection ensures your car meets the state’s safety and performance standards—but many vehicles fail on the first try.
At Ken’s Automotive & Transmissions, we help drivers in Frederick and beyond understand what to expect during the inspection process—and how to avoid common pitfalls. Here are some of the most frequent reasons cars fail Maryland State Inspection, and how you can prepare.
Worn or Damaged Tires
Tires are one of the most common failure points. Maryland inspectors check for:
- Tread depth (must be at least 2/32”)
- Uneven wear
- Visible damage like bulges or dry rot
Tip: If your tires are looking worn or have bald spots, it’s a good idea to replace them before inspection.
Brakes That Don’t Meet Standards
Your vehicle’s braking system must perform safely and efficiently. Common issues include:
- Thin or worn brake pads
- Scored or warped rotors
- Leaking brake fluid or damaged brake lines
Pro tip: If you’ve noticed squeaking, grinding, or soft brake pedal feel, get your brakes checked before scheduling the inspection.
Faulty or Burned-Out Lights
Inspectors check all exterior lights to make sure they are working properly, including:
- Headlights (high and low beams)
- Brake lights
- Turn signals
- Reverse lights
- Tag and marker lights
Even a single burned-out bulb can result in a failed inspection—so check them all before heading in.
Suspension and Steering Issues
Your vehicle must steer smoothly and maintain proper alignment. The inspection will flag:
- Loose or worn ball joints or tie rods
- Damaged shocks or struts
- Excessive play in the steering wheel
These issues can impact safety, so they’re taken seriously during inspection.
Windshield and Wipers
Visibility is a big part of safety, which means your windshield and wipers must be in good condition.
- Cracks or chips in the driver’s line of sight can lead to failure
- Wipers must function properly and clear the windshield fully
- Windshield washer fluid must spray correctly
Exhaust System Leaks
A leaky or loud exhaust system is not just a nuisance—it’s a health and safety concern. Inspectors check for:
- Rust holes or damage in the muffler or exhaust pipes
- Exhaust leaks near the cabin
- Missing or loose components
Dashboard Warning Lights
If your Check Engine Light or any other warning lights are illuminated, your vehicle may automatically fail. While not all warning lights are automatic disqualifiers, a lit Check Engine Light is a red flag that needs attention.
Improper Emissions Equipment
While the state inspection is separate from the Maryland emissions test, inspectors still check to make sure emissions-related components (like catalytic converters) are present and intact. Missing or tampered parts can cause your vehicle to fail inspection.
