If you’ve got a trailer or caravan sitting in the driveway, you might be wondering when you actually need a roadworthy certificate in QLD. It’s one of those things people only think about when it’s time to sell or re-register, but it’s worth knowing the rules before that moment arrives. Especially in Queensland, where the guidelines for trailers and caravans are pretty specific.
At Coastwide Service Centre in Molendinar, we help people all over the Gold Coast with roadworthy certificates, not just for cars, but for trailers and caravans too. If you’re unsure about what gets checked or when you need one, this guide will clear things up.
When do you need a Roadworthy Certificate for a trailer or caravan?
In Queensland, it comes down to the weight of your trailer or caravan. If it has an Aggregate Trailer Mass (ATM) between 750kg and 3,500kg, you’ll need a roadworthy certificate when:
- You’re selling it (even if it’s a private sale)
- You’re transferring registration
- You’re re-registering an unregistered trailer or caravan
If your trailer or caravan is under 750kg ATM, no roadworthy certificate is needed. That generally includes the smallest box trailers, but not much else.
What’s checked during a roadworthy certificate inspection?
Just like with cars, the point of a roadworthy certificate inspection is to check that your trailer or caravan is safe to be on the road. It’s not about cosmetics, it’s about safety. Here’s what inspectors like us at Coastwide Service Centre will check:
- Tyres and wheels: Tread depth, tyre condition, and correct load ratings.
- Brakes: If the trailer or caravan has brakes (mandatory for anything over 750kg ATM), they need to work properly.
- Suspension: All components must be in good shape and secure.
- Couplings and safety chains: These need to be strong, correct for the weight, and compliant with standards.
- Lights and reflectors: Brake lights, indicators, and reflectors must all work and be visible.
- Chassis and Frame: No cracks, rust, or damage that would compromise safety.
- Bodywork: Things like doors, windows, and access points must be secure and functional.
Every roadworthy certificate we issue follows these checks carefully. If we spot a problem, we’ll let you know exactly what needs fixing.

Common reasons trailers and caravans fail the roadworthy check
We’ve seen it all here in Molendinar, sometimes it’s the little things that trip people up when going for a roadworthy certificate. The most common issues we see with trailers and caravans include:
- Worn or mismatched tyres
- Faulty or missing lights
- Rusted safety chains or couplings
- Cracked chassis or compromised suspension
- Brakes that don’t function correctly or are unbalanced
A quick pre-inspection check at home can save you time and money. If you’re unsure, you can always bring it in and we’ll give it a once-over before doing the formal inspection.
Do modifications affect your roadworthy certificate?
Absolutely. If you’ve modified your trailer or caravan, added a bigger axle, new suspension, different brakes, or other upgrades, these mods need to comply with Queensland regulations. If they don’t, you might fail your roadworthy certificate inspection.
We’ve worked with plenty of locals on the Gold Coast who’ve added new features to their caravans. Some are fine, others need engineering approval or extra certification. If you’re not sure whether your modifications meet the rules, ask us at Coastwide Service Centre. We’ll point you in the right direction before you book your roadworthy certificate check.
How long is the roadworthy certificate valid for?
In QLD, once you get a roadworthy certificate, it’s valid for:
- 2 months or 2,000 km (whichever comes first) for private sales
- 3 months or 1,000 km for licensed motor dealers
That means you have a limited window to complete your sale or registration. Don’t delay if you’re planning to sell your trailer or caravan, get the inspection booked and the paperwork sorted quickly.
