7 Signs Your Car May Fail An Inspection Advice From Mobile Roadworthy Brisbane

A mobile roadworthy Brisbane certificate is more than just a piece of paper—it’s a reflection of your vehicle’s safety and legal compliance on Queensland roads. If you’re planning to sell your car, transfer registration, or re-register an unregistered vehicle, you’ll need this certificate. But how can you tell if your car is roadworthy before booking an inspection?

We are committed to keeping you safe and informed. Here are the top signs your car may not be roadworthy—and what you can do about them.

1. Worn or Bald Tyres:

Tyres are a critical component of vehicle safety. If your tyres are bald, worn unevenly, or below the legal tread depth of 1.5mm, your car may fail the roadworthy test. Cracks, bulges, and exposed cords are also red flags.

What to Do:

Check your tyre tread using a tread depth gauge or the "coin test." Replace tyres if they’re worn or showing signs of damage.

2. Faulty Lights and Indicators:

All exterior lights must be working correctly, including headlights, brake lights, reverse lights, and turn signals. Dim, flickering, or non-functional lights are a common reason for car roadworthy Brisbane failure.

What to Do:

Please have someone help you check each light while you activate it. Replace blown bulbs and ensure lenses are clean and free from cracks.

3. Brakes Making Noise or Feeling Spongy:

Brakes that squeal, grind, or feel unresponsive when pressed are a serious safety hazard. A vehicle with brake issues is unlikely to pass a roadworthy inspection.

What to Do:

If you suspect brake problems, visit a mechanic immediately. You may need new pads or discs or a brake fluid top-up.

 4. Cracked or Chipped Windscreen:

A damaged windscreen—especially in the driver’s field of vision—can obstruct your view and lead to roadworthy failure. Even small cracks can proliferate and compromise safety.

What to Do:

If the damage is minor and not in the line of sight, repairs may be sufficient. Otherwise, a complete replacement might be necessary.

5. Rust or Body Damage:

Surface rust isn’t usually a problem, but structural rust or sharp edges from damage can affect the integrity and safety of your vehicle.

What to Do:

Inspect your car for rust near seatbelt mounts, the undercarriage, and door frames. If necessary, consider professional rust treatment or panel repairs.

6. Suspension or Steering Problems:

A car that pulls to one side, feels unstable, or makes knocking noises over bumps could have worn suspension components or steering issues. These can impact your control and stability on the road.

What to Do:

Get a suspension check from a licensed mechanic. Replacing worn bushings, shocks, or ball joints may be required.

7. Leaks or Engine Smoke:

Visible oil, coolant, or transmission fluid leaks under your car—or blue/white smoke from the exhaust—are warning signs of mechanical issues that can lead to a failed car safety certificate Brisbane inspection.

What to Do:

Address any leaks or smoke as soon as possible. Regular servicing helps prevent major issues from developing.
