Roadworthy inspections focus on safety-critical components that protect you and other road users. Understanding what inspectors look for is the first step to passing your test on the first attempt. The most common failure points include braking systems, tyre condition, lighting functions, and steering components—all areas that directly impact vehicle safety.
At Balwyn Automotive, we've seen hundreds of vehicles come through our workshop, and the failures rarely come as surprises to vehicle owners. Most issues develop gradually and are easily spotted during routine maintenance checks. By addressing these areas proactively, you can avoid the frustration and expense of retesting.
Brakes are the primary reason vehicles fail roadworthy inspections. Inspectors check brake pad thickness, rotor condition, brake fluid quality, and overall stopping performance. If your brakes feel soft, make noise, or don't respond as firmly as they once did, it's time for professional assessment. Our brake and clutch replacement service ensures your stopping power meets roadworthy standards and keeps you safe on Canterbury and Blackburn roads.
Tyre condition is equally important—inspectors measure tread depth, check for uneven wear, cracks, or damage, and ensure all four tyres meet minimum safety requirements. Most regulations require at least 1.6mm of tread depth, though 3mm is safer for wet weather. Lights that don't function—headlights, tail lights, indicators, and brake lights—are automatic failures. Test every light function before your inspection and replace any blown globes immediately.
Steering components must be tight and responsive. Inspectors check for worn tie rods, suspension play, and power steering function. If your steering feels loose, wanders on straightroads, or pulls to one side, have our suspension and steering repair specialists assess the problem before your test.


Two weeks before your inspection, schedule a comprehensive pre-inspection service with a qualified mechanic. This gives you time to address any identified issues without rushing. Check your engine oil level and top up if necessary—low oil can indicate underlying engine problems that might be flagged. Ensure your battery is in good condition; a weak battery can cause electrical system failures, affecting lights and other components.
Clean your vehicle thoroughly, especially underneath, so inspectors can see components clearly. Top up windscreen washer fluid, test all wipers, and ensure your number plate is clean and securely attached. Check that your spare tyre, jack, and warning triangle are present and functional. Verify all seat belts are working properly and that your handbrake holds the vehicle securely on a slope.

Our engine diagnostics can also identify any hidden faults that electronic systems might detect during the official inspection.
DIY maintenance is valuable, but roadworthy inspections require professional expertise and specialized equipment. Inspectors use diagnostic tools to check emissions, braking performance, and electrical systems that you can't assess with basic tools. By having a professional service your vehicle beforehand, you benefit from their knowledge of exactly what inspectors look for and their ability to bring your vehicle up to standard.
