Getting a trailer roadworthy certificate in Queensland is a key step when you want to sell, re-register, or transfer ownership of your trailer. Without this certificate, you may face delays or legal issues. This guide explains when you need the certificate, what the inspection covers, common problems that cause failures, and how mobile inspections can make the process easier.
When You Need a Trailer Roadworthy Certificate
A trailer roadworthy certificate confirms that your trailer meets safety standards required by Queensland authorities. You will need this certificate in several situations:
Selling your trailer: Buyers want assurance the trailer is safe and compliant.
Re-registering your trailer: If your registration has expired or you are renewing it.
Transferring ownership: When you sell or give your trailer to someone else, the new owner needs a valid certificate.
Without a current roadworthy certificate, you cannot legally register or transfer the trailer. This can delay sales or cause fines if you use an unregistered trailer on public roads.
Please note that if you are transferring your Trailer registration from another State or Territory into Queensland, you will require a HVRAS Measure Up along with your Roadworthy Certificate. This also applies to Trailers that have been unregistered for more than 3 months in Queensland as well.
What Inspectors Check During the Roadworthy Inspection
The inspection covers key safety components to ensure your trailer is safe to tow. Inspectors focus on:
Tyres: Condition, tread depth, and correct pressure.
Lights: Functioning brake lights, indicators, tail lights, and reflectors.
Brakes: For trailers with brakes, these must work properly and meet standards.
Suspension: No excessive wear or damage that could affect stability.
Coupling: The hitch and safety chains must be secure and in good condition.
Structure: The chassis and frame should be free of dangerous rust, cracks, or damage.
Inspectors use a checklist to verify each item meets Queensland safety regulations. If any part fails, you will need repairs before the certificate is issued.
Common Reasons Trailers Fail the Inspection
Many trailers fail the roadworthy inspection due to avoidable issues. The most frequent problems include:
Faulty lights: Burnt-out bulbs, broken lenses, or wiring faults.
Wiring issues: Corroded or damaged wiring causing lights to malfunction.
Rusted chassis: Structural rust weakens the frame and can be unsafe.
Worn tyres: Bald or damaged tyres that do not meet tread requirements.
Brake problems: Worn brake pads or faulty brake mechanisms.
Fixing these issues before the inspection saves time and money. Regular maintenance helps keep your trailer roadworthy and ready for sale or registration.
Mobile Trailer Inspections for Convenience
Many inspection services in Queensland offer mobile inspections. This means an inspector can come to your home, yard, or workplace to check your trailer. Mobile inspections provide several benefits:
Save time: No need to drive your trailer to a workshop.
Flexible scheduling: Choose a time that fits your routine.
Comfort: Stay on-site while the inspection happens.
Mobile inspections are especially useful for large trailers or those difficult to transport. They also allow you to get a quick assessment and know what repairs are needed before listing your trailer for sale.
Next Steps After Getting Your Roadworthy Certificate
Once your trailer passes inspection and you receive the roadworthy certificate, you can:
Proceed with selling your trailer confidently.
Complete the transfer of ownership paperwork.
Re-register your trailer with the Queensland Department of Transport.
Keep the certificate safe as you may need to present it during registration or sale. If your trailer fails, address the issues promptly and book a re-inspection.
