When it comes to selling or re-registering a used car in Queensland, one phrase always comes up: roadworthy inspection. It’s the gatekeeper between you and a legal sale or a car that can stay on the road.
Many drivers stress about whether their used car will pass, but here’s the thing, most failures come down to predictable, simple issues that can be checked before you book your inspection. If you take the time to prepare, you’ll avoid wasted trips, delays, and repeat fees.
At Coastwide Service Centre, we’ve been helping Queensland drivers prepare for and pass their roadworthy inspection for years. With our mobile service, we know exactly what inspectors are looking for and the kinds of problems that pop up most often. In this guide, we’ll share a detailed checklist so you can get your car ready and sail through the process with confidence.
Why a roadworthy inspection matters
A roadworthy inspection is designed to confirm that your used car is safe enough for the road. It doesn’t mean your car is in perfect condition or guaranteed to last for years, but it does mean it meets the legal minimum standards of safety.
When your car passes, you get a roadworthy certificate, which is essential if you’re:
- Selling your car
- Re-registering your car after the rego has lapsed
- Transferring registration to another person
Failing the roadworthy inspection doesn’t mean your car is a write-off. It just means there are issues that need to be fixed before the certificate can be issued. The good news? Most of these issues are obvious if you know where to look.
Your ultimate roadworthy inspection checklist
Here’s a breakdown of the most important areas to check before you book your roadworthy inspection.
1. Tyres and wheels
Tyres are one of the most common reasons used cars fail their roadworthy inspection. Inspectors will look at:
- Tread depth: The legal minimum in Queensland is 1.5mm, but anything close to that may still fail. It’s safer to replace tyres once they hit 2–3mm.
- Condition: Cracks, bulges, and uneven wear are all reasons to fail.
- Matching tyres: Ideally, tyres should be the same type and size on each axle.
- Spare tyre: Some inspectors check the spare too, so don’t overlook it.
Tip: If your tyres are near the legal limit, replace them before your roadworthy inspection. It’s cheaper than failing and having to book again.
2. Brakes
No inspector will issue a roadworthy certificate if your brakes aren’t working properly. Checks include:
- Brake pads: If they’re worn down, you’ll need to replace them.
- Discs and drums: Warped or scored rotors are a fail.
- Handbrake: It must hold the car firmly on a slope.
Tip: If you’ve noticed squealing, grinding, or longer stopping distances, book a brake service before your roadworthy inspection.
3. Lights and indicators
It’s surprising how many people fail because of something as small as a blown bulb. Inspectors will check:
- Headlights (high and low beam)
- Indicators
- Brake lights
- Number plate lights
- Reverse lights
Tip: Grab a friend and test every light before your roadworthy inspection. Replacing a bulb takes minutes and costs almost nothing.
4. Windscreen and windows
The windscreen is another hot spot for roadworthy inspection failures. Inspectors look for:
- Cracks and chips: Anything in the driver’s line of sight is a fail.
- Wipers: They must clear the screen effectively.
- Washer jets: They must spray fluid properly.
Tip: Replace your wiper blades if they leave streaks. If your windscreen has a large crack, get it repaired or replaced before booking.
5. Seatbelts
Seatbelts save lives, which is why inspectors are strict about them. They’ll check:
- Condition: No frays, tears, or damage.
- Locking: Belts must lock firmly when pulled quickly.
- Buckles: They must latch and release smoothly.
Tip: If any seatbelt doesn’t retract properly, it may need replacing. Don’t wait until the roadworthy inspection to find out.
6. Steering and suspension
This is where problems like CVT transmission slips can tie in. Even though the transmission itself isn’t torn apart during a roadworthy inspection, the overall handling of the used car matters. Inspectors will check:
- Steering response: No excessive play in the wheel.
- Suspension wear: Worn shocks or leaking struts are fails.
- Ball joints and bushings: Must be solid, not loose.
- CV joints: Torn boots or clicking noises are a problem.
Tip: If your used car feels floaty, bouncy, or clunks over bumps, get the suspension looked at before the roadworthy inspection.
7. Transmission service
For cars with automatic or CVT transmissions, inspectors want to see predictable, safe performance. That means no shuddering, slipping, or hesitation when changing gears.
- Fluid levels: Leaks or low fluid are automatic fails.
- Delayed engagement: A big warning sign.
- Shuddering: Unsafe and likely to cause rejection.
Tip: If you haven’t serviced your transmission in years, now is the time. A transmission service can prevent a roadworthy inspection fail and extend the life of your gearbox.
8. Exhaust and emissions
Exhaust leaks or excessive smoke are a common reason for failure. Inspectors will check:
- Exhaust pipes for rust or damage
- Muffler condition
- Smoke levels
Tip: If you see blue or black smoke when driving, book a mechanic before your roadworthy inspection.
9. Body and structure
The bodywork doesn’t need to be perfect, but it does need to be safe. Inspectors will fail cars with:
- Sharp edges from damage
- Major rust that compromises safety
- Loose panels
Tip: Cosmetic dents are fine, but rust holes or jagged damage will stop you passing.
10. General checks
Other things inspectors will look at include:
- Mirrors must not be cracked or loose.
- Horn must work properly.
- Doors and windows must open and close.
- Speedometer must work.
Tip: Do a quick run-through yourself. If something doesn’t work, fix it before the roadworthy inspection.
How long does a roadworthy inspection take?
Most roadworthy inspections take less than an hour. If the used car fails, you’ll usually get a report listing the problems. You then have 14 days to fix them and book a reinspection.
This is why preparation is so important. If you follow this checklist, you’ll save yourself the frustration of repeat bookings.
Why used cars fail roadworthy inspections
At Coastwide Service Centre, the most common reasons we see used cars fail are:
- Tyres too worn
- Brake pads gone
- Cracked windscreen
- Faulty seatbelts
- Transmission issues
Notice how many of these are on the checklist above? By spending an afternoon checking your car, you can avoid almost all of them.
Used car buyers: don’t stop at the roadworthy inspection
A roadworthy inspection shows that a car is legally safe today, but it’s not the same as a full mechanical inspection. For peace of mind, especially if you’re buying a car with a CVT transmission, consider booking a pre-purchase inspection as well. That way, you’ll know whether the used car is safe and whether it’s likely to stay reliable.
