Truck Certificate of Inspections, or COIs, are required every year and are intended to ensure the compliance and safety of heavy-duty vehicles. According to the Department Main Roads & Transport, this certificate attests that a truck or other heavy vehicle has been inspected and meets the relevant safety requirements. 

A heavy vehicle COI typically includes a comprehensive examination of various components including:

  • Brakes
  • Tyres
  • Lights
  • Steering
  • Suspensions
  • Exhaust Systems
Trailer Certificate of Inspection (COI) Caboolture & Brisbane

Trailer COIs

A Trailer COI, ensures that the trailer meets all necessary safety standards. This is standard for heavy trailers used for commercial purposes or transporting heavy loads.

It also means that the trailer has had regular inspections and maintenance to ensure its continued safety on the road. Obtaining a Trailer COI is a legal requirement in Queensland.

Do I Need Mobile Roadworthy Vehicle Inspections? 

There are many circumstances where you will need mobile roadworthy inspections or a Diesel Repair Service. No matter the situation, the KS Mobile Diesel team is happy to perform roadworthy inspections, coming to your location and inspecting vehicles, trailers, trucks and other diesel equipment. You’ll need to book mobile roadworthy vehicle inspections if you are:

Selling Your Vehicle

In Queensland you’re required to obtain a current Safety Certificate or COI when selling a registered vehicle.

Registration Expiration

If your vehicle registration lapses, you'll need a Safety Certificate or COI to re-register it with the Queensland Department of Transport.

Interstation Registration Transfer

Following an interstate vehicle sale, you’ll need to transfer the registration to a Queensland address. A vehicle that hasn’t previously been registered in Queensland requires a HVRAS certificate after undergoing a HVRAS inspection Brisbane service or Safety Certificate.

HVRAS Measure-Ups

HVRAS measure-ups assess the dimensions, weight and identification markers on trailers and heavy vehicles to ensure they comply with QLD’s road rules.

Frequently Asked Questions

What are mobile vehicle inspections?

Mobile vehicle inspections are an onsite service that can provide roadworthy inspections and safety certificates at your location. There’s no need to book your vehicle into a mechanic’s workshop, a mobile inspector can visit you and perform the roadworthy inspection on the spot!

What is checked during roadworthy inspections in Queensland?

Roadworthy inspections are carried out on light vehicles, motorbikes, and light trailers. The mobile vehicle inspections checklist covers a range of parts throughout the vehicle including wheels and tyres, lights, brakes and the engine. The Department of Transport website provides a full list of everything that is checked during roadworthy inspections.

What is a certificate of inspection?

While smaller vehicles and cars require a roadworthy certificate, heavy vehicles must obtain a Certificate of Inspection (COI). Vehicles that require a COI include trucks, buses, heavy trailers and heavy vehicles. If you own a vehicle that requires a COI then you must always have a valid certificate. COIs expire every 12 months and can typically be renewed by a mobile vehicle inspection service. More information regarding vehicles that require a COI, exemptions and renewal schedules can be found on the QLD Department of Transport website.

Can you drive an unregistered car to get roadworthy inspections in Queensland?

Yes, the QLD Department of Transport permits you to drive an unregistered vehicle for the purpose of getting roadworthy inspections prior to registration. Detailed information regarding mobile vehicle inspections can be found on the QLD Department of Transport website.


Can you sell your car without roadworthy inspection in Queensland?

If you are selling a registered vehicle in Queensland then you are legally required to get a roadworthy certificate to show that the vehicle is not defective. You don’t need a roadworthy inspection if you are selling a vehicle without registration. If you are purchasing a vehicle from out of Queensland, you will need a roadworthy certificate to register the vehicle locally.


What is a HVRAS Measure-Up?

A HVRAS Measure-Up is carried out on vehicles with a gross vehicle mass greater than 4.5 tonnes and trailers with an aggregate mass greater than 750kg. A HVRAS Measure-Up checks the dimensions, weight and identification tags attached to your vehicle or trailer to ensure they comply with Queensland legislation. For more information regarding the scheme, head to the QLD Department of Transport website or call our friendly heavy vehicle inspection Brisbane team.

What happens if I fail my inspection?

When a vehicle fails an inspection, there are normally defects or problems that will need to be resolved before re-inspection. For re-inspection, it’s important to book a diesel truck mechanic to inspect the vehicle, identify mechanical problems, and provide necessary diesel repairs for defect writeoffs. Failing an inspection doesn’t mean that the truck or trailer cannot be repaired.
