Keeping your car roadworthy is not just a legal requirement in New Zealand, it’s also critical for safety. Unfortunately, many vehicles fail their Warrant of Fitness (WoF) inspections due to common and often preventable issues. Using insights from NZTA data, we’ve compiled the top reasons for WoF failures and tips to address them.
1. Lighting and Signaling Issues
According to NZTA, lighting and signaling faults account for over 35% of WoF failures, making it the most common reason for inspections not passing. Broken or dim headlights, malfunctioning indicators, and unlit brake lights can compromise visibility and safety.
How to Prevent This:
- Regularly inspect all external lights, including indicators and brake lights.
- Replace burnt-out bulbs promptly.
- Clean lenses to ensure brightness is not diminished by dirt or grime.
2. Tyre Condition
Tyre-related issues are the second most common reason for WoF failures, contributing to approximately 28% of rejections. Problems often include insufficient tread depth (below 1.5mm), uneven wear, or visible damage such as cuts or bulges.
How to Prevent This:
- Check tyre tread depth regularly and replace tyres when they approach the legal minimum.
- Maintain proper tyre pressure to avoid uneven wear.
- Inspect tyres for any visible damage, including sidewall cracks or punctures.
3. Brakes and Brake Pads
Faulty brakes are a critical safety concern and account for around 15% of WoF failures. Common problems include worn brake pads, leaking brake fluid, or a spongy brake pedal.
How to Prevent This:
- Listen for squealing or grinding noises, which could indicate worn pads.
- Check brake fluid levels and look for leaks.
- Schedule routine brake system inspections, especially before long trips.
4. Suspension and Steering Systems
NZTA data shows that suspension and steering defects cause roughly 12% of WoF failures. Worn suspension components or misaligned steering can affect vehicle handling and safety.
How to Prevent This:
- Pay attention to unusual noises or vibrations while driving.
- Check for uneven tyre wear, which can indicate suspension issues.
- Have your suspension and steering systems inspected during regular maintenance.
5. Windscreen and Wipers
A clear view of the road is essential for safe driving. Cracked windscreens and malfunctioning wipers contribute to nearly 10% of WoF failures.
How to Prevent This:
- Replace wiper blades if they leave streaks or squeak when in use.
- Repair or replace cracked windscreens to avoid structural weakness.
- Ensure washer fluid is topped up regularly.
Why Passing a WoF Matters
Failing a WoF not only disrupts your schedule but also poses safety risks to you and others on the road. Staying proactive about vehicle maintenance can help you avoid common pitfalls and ensure a smoother inspection process.
Benefits of Staying Roadworthy:
- Avoid fines for driving without a valid WoF.
- Reduce the risk of accidents caused by mechanical faults.
- Extend the lifespan of your vehicle.
