Buying a used car in Queensland can be exciting, especially when you find a good deal. But before you hand over your cash, there’s something important you shouldn’t ignore: the roadworthy certificate. It might not be the most exciting part of car shopping, but it’s one of the most important. Without it, you could end up buying a car that’s not safe, legal, or even worth what you paid.
At Coastwide Service Centre in Molendinar, we’ve helped heaps of locals across the Gold Coast make sure their cars are roadworthy and compliant. If you’re buying or selling a vehicle around Molendinar, Ashmore, Parkwood, or Southport, we’re here to help with inspections and advice. Here’s everything you need to know before buying that used car.
What is a roadworthy certificate?
In Queensland, a roadworthy certificate (also called a safety certificate) proves that a vehicle is safe to drive and meets minimum safety standards. It’s mandatory if:
- You’re selling a registered vehicle
- You’re transferring registration
- You’re re-registering an unregistered vehicle
A valid roadworthy certificate means the vehicle has passed key safety checks on things like brakes, tyres, steering, suspension, windscreen, lights, and more. Without it, you’re risking buying a car that could be unsafe or need expensive repairs.
Why you should ask for the roadworthy certificate
If the seller doesn’t provide a roadworthy certificate, it’s a red flag. In QLD, it’s their legal responsibility to supply one when selling a registered vehicle. No certificate? You’re either dealing with an unregistered vehicle or a seller who hasn’t maintained it properly.
At Coastwide Service Centre, we often see cars come in for a roadworthy certificate after a buyer asks for it, and sometimes, those cars fail the inspection. That’s why asking for the certificate upfront is one of the easiest ways to protect yourself from buying a dud.
How to inspect a used car before buying
Even if a roadworthy certificate is provided, it doesn’t hurt to know how to inspect a used car yourself. Here are a few things to check when you go to see the vehicle:
- Tyres: Check for uneven wear or bald spots.
- Brakes: Listen for squealing or grinding sounds.
- Steering: Make sure it feels smooth and not too loose or tight.
- Suspension: Bounce each corner of the car, it should settle quickly without excessive movement.
- Lights: Ensure headlights, brake lights, and indicators work properly.
- Windscreen: Look for cracks or chips, especially in the driver’s line of sight.
- Rust or damage: Check the body, underneath the car, and inside door frames.
These quick checks don’t replace a professional inspection, but they’re a handy part of your vehicle check before buying.
What the roadworthy certificate covers
A roadworthy certificate isn’t a full mechanical check, it’s more about safety. It covers:
- Tyres
- Brakes
- Steering and suspension
- Lights and indicators
- Windscreen and wipers
- Seats and seatbelts
- Structural integrity (no major rust or damage)
It won’t tell you if the car needs an oil change, has a worn clutch, or has mechanical issues brewing. That’s why it’s smart to get a separate pre-purchase inspection too, especially if you want peace of mind. Coastwide Service Centre in Molendinar offers both roadworthy certificates and full pre-purchase inspections, so you know exactly what you’re buying.

How to Verify the Roadworthy Certificate
Once the seller shows you the certificate, check:
- That it’s issued by an approved inspection station (like us at Coastwide Service Centre)
- The date, it’s only valid for 2 months or 2,000km from issue
- The VIN and registration number match the car
If anything looks off, or the certificate is expired, you should ask for a fresh inspection. Sellers are required to provide a current roadworthy certificate, so don’t accept excuses.
Don’t skip the vehicle check before buying
Getting a vehicle check before buying is one of the smartest things you can do. Even with a roadworthy certificate, a comprehensive inspection can reveal things that might cost you down the track. Think of it as a safety net, no one wants to buy a used car only to fork out thousands on repairs a few weeks later.
If you’re on the Gold Coast, bring the car to us at Coastwide Service Centre in Molendinar. We’ll check the vehicle thoroughly, let you know if it’s worth buying, and advise on any hidden issues.

Common problems missed without an inspection
We’ve seen plenty of buyers regret skipping the extra check. Some common problems that pop up include:
- Worn timing belts
- Leaking oil seals
- Failing transmissions
- Battery or electrical issues
- Undiagnosed accident damage
A roadworthy certificate focuses on safety, not mechanical wear. So if you want to avoid nasty surprises, an extra vehicle check before buying is worth the small cost.
Ask about the car’s service history
Always ask the seller for the service history. A well-maintained car should have records of oil changes, services, and any repairs. If they’ve lost the records or can’t provide them, that’s another warning sign.
At Coastwide Service Centre, we can give you advice on what to look for in service records and tell you if the maintenance matches the car’s condition.
What happens if the car fails the roadworthy inspection?
If the car you want to buy fails its roadworthy certificate inspection, the seller is responsible for fixing the issues before selling it to you. They’ll have 14 days to repair and re-submit the car for inspection.
That’s why it’s smart to wait until the roadworthy certificate is issued before finalising the deal. Don’t risk paying first and hoping the seller will sort it later, it’s safer to let them handle the repairs.
