# Top Reasons Cars Fail Roadworthy Inspections (and How to Avoid Them)

![](https://totallymobileroadworthy.com.au/wp-content/uploads/2024/03/machinic-man-in-customer-car-writing-to-the-clipbo-2023-11-27-05-10-04-utc.jpeg)

When it’s time to sell or re-register your car, passing a Queensland roadworthy inspection is a legal requirement. However, many vehicles fail these checks due to preventable issues. To save yourself time, money, and frustration, it’s important to know what inspectors look for and how to prepare your car. Here’s a rundown of the top reasons cars fail roadworthy inspections—and practical tips to ensure your vehicle passes with flying colours.

### 1. Worn or Damaged Tyres
Your tyres play a vital role in maintaining grip and safety on the road. Inspectors will check tyre tread depth, sidewall condition, and overall wear.

**How to Avoid Failure:**

- Regularly check your tyre tread depth; the legal minimum in Queensland is 1.5mm.
- Inspect for visible damage such as cracks, bulges, or punctures.
- Rotate your tyres every 10,000km to ensure even wear.
- Don’t forget to check the spare tyre—it needs to meet roadworthy standards too!

### 2. Ineffective Brakes
Faulty brakes are one of the most common reasons vehicles fail inspections. Worn pads, damaged rotors, or low brake fluid can significantly impact performance.

- Listen for squealing or grinding noises when braking—these are signs of worn pads.
- Have your brakes inspected during regular servicing.
- Ensure the brake pedal feels firm, not spongy, and the handbrake operates correctly.
- Replace worn pads and rotors as needed to maintain optimal braking power.

### 3. Faulty Lights and Indicators
Your car’s lights and indicators are essential for visibility and communication on the road. Burnt-out bulbs, cracked lenses, or misaligned headlights can all lead to inspection failure.

- Check all external lights, including headlights, indicators, brake lights, and reverse lights, regularly.
- Replace any faulty or dim bulbs promptly.
- Clean your light lenses to ensure maximum brightness.
- Ensure headlights are properly aligned to avoid dazzling other drivers.

### 4. Suspension and Steering Issues
The suspension and steering system are critical for control and comfort. Issues such as worn shock absorbers or loose steering components are red flags for inspectors.

- Pay attention to unusual noises, like clunks or squeaks, while driving.
- Test for excessive bouncing when you press down on the car’s corners.
- Have your suspension and steering system checked during regular servicing.
- Replace worn or damaged components promptly to ensure smooth handling.

### 5. Windscreen and Wiper Problems
Your windscreen and wipers are essential for visibility. Cracks, chips, or damaged wipers can compromise safety and fail an inspection.

- Repair small windscreen chips before they spread into larger cracks.
- Replace wipers that leave streaks or don’t clear effectively.
- Ensure washer fluid reservoirs are filled and functional.
- Avoid using adhesive stickers that obstruct the driver’s view.

### 6. Exhaust System Defects
A damaged or excessively noisy exhaust system can lead to inspection failure. Inspectors also check for emissions compliance.

- Regularly inspect the exhaust for visible damage or excessive noise.
- Address rattling or hissing sounds, which may indicate a leak.
- Ensure your vehicle meets emissions standards.

### The Importance of Regular Maintenance
Routine maintenance is the best way to avoid [roadworthy inspection](https://totallymobileroadworthy.com.au/) failures. By addressing small issues before they become major problems, you’ll save time and money—and keep your vehicle safe on the road.

**Top Maintenance Tips:**

- Stick to a regular service schedule to catch potential issues early.
- Perform basic checks, like inspecting tyres, lights, and fluids, every few weeks.
- Act promptly when warning lights appear on your dashboard.
- Keep a log of repairs and maintenance for your records.
