Avoid Fails: Common Issues That Stop Your Car Getting a Roadworthy Certificate
Learn the common issues that cause cars to fail a roadworthy certificate and expert mechanic tips to prepare your vehicle for a smooth inspection.

Getting a roadworthy certificate Narre Warren South is an essential step when selling, transferring, or re-registering a vehicle in Victoria. While many drivers focus on the paperwork, failing to prepare your car properly can result in delays, extra costs, or even a failed inspection. Understanding common issues that prevent cars from passing and addressing them early with a qualified mechanic is the key to a smooth roadworthy process.
Why a Roadworthy Certificate Matters
A roadworthy certificate is more than just a legal requirement—it’s a confirmation that your car meets minimum safety standards. The inspection covers critical areas including brakes, tyres, lights, steering, suspension, and other safety systems. Driving without ensuring your car is roadworthy can put you, your passengers, and other road users at risk.
A professional mechanic not only helps you pass the inspection but also ensures your vehicle is safe for everyday use.
Common Issues That Cause RWC Fails
1. Worn or Damaged Tyres
Tyres are one of the most frequent reasons cars fail a roadworthy certificate. Inspectors check for:
-
Minimum tread depth of 1.5mm
-
Uneven wear patterns
-
Cuts, bulges, or other visible damage
Tip: Have a mechanic inspect your tyres before the RWC. Replacing or repairing tyres in advance saves time and prevents failure.
2. Faulty Brakes
Brakes are critical for safety, and worn or faulty components can lead to an immediate fail. Inspectors assess:
-
Brake pads and discs
-
Brake fluid levels
-
Overall braking performance
A professional mechanic Skye can identify worn brakes, adjust components, and top up fluids to ensure your car meets the standard.
3. Non-Working Lights and Indicators
All lights—including headlights, tail lights, brake lights, and indicators—must function correctly. Non-working bulbs or faulty wiring are common reasons for failed inspections.
Tip: Check every light before your appointment and replace any that are burnt out. Your mechanic can also test electrical systems to ensure everything is in order.
4. Steering and Suspension Issues
Problems with steering or suspension affect vehicle control and can make your car unsafe. Inspectors check:
-
Worn or damaged suspension components
-
Steering play or misalignment
-
Leaks in shock absorbers
Fixing these issues with a mechanic before the inspection increases the chances of passing.
5. Windscreens and Wipers
Cracked or chipped windscreens and worn wiper blades can impair visibility and are common reasons for RWC failures.
Tip: Repair minor windscreen damage and replace worn blades prior to inspection. A mechanic can advise whether the windscreen is repairable or requires replacement.
6. Fluid Leaks
Leaks in brake fluid, coolant, or other essential systems are red flags for inspectors. Not only can they result in a failed RWC, but they also pose safety hazards.
Having a mechanic inspect and repair leaks ensures your vehicle operates safely and passes the inspection.
7. Seatbelts and Safety Equipment
Faulty seatbelts, airbags, or other safety equipment can cause instant failure. Inspectors check that all restraints are functional and meet safety standards.
