COI vs Roadworthy: Which Inspection Do You Need?
A Certificate of Inspection and a Queensland Safety Certificate both involve vehicle safety — but they aren't interchangeable.
The right inspection depends on what the vehicle is and how it's being used. For everyday light vehicles, a Safety Certificate is usually the one people mean by a Roadworthy. COIs apply to particular vehicle and commercial-use categories.
Queensland Safety Certificate
Commonly called a Roadworthy or RWC. Usually relevant to light-vehicle registration and ownership-transfer situations.
Certificate of Inspection — COI
A periodic inspection required for particular vehicle categories and uses, including booked-hire vehicles.
The Main Difference Between a COI and a Roadworthy
Both inspections are concerned with vehicle safety, but the reason you're getting the inspection — and the type of vehicle involved — is different.
Safety Certificate
Certificate of Inspection
Don't start by asking “Which certificate sounds right?” Start with the vehicle type and what it is being used for. That determines the inspection requirement.
Which Vehicles Commonly Need a COI?
A COI is not simply a different version of a Roadworthy. Queensland requires COIs for specific categories of vehicle and use.
Booked-Hire & Rideshare Vehicles
Vehicles used to provide booked-hire services generally need a current COI unless an exemption applies.
Taxis & Limousines
These are among the Queensland passenger-transport vehicle categories that require periodic COI inspections.
Buses & Certain Public Passenger Vehicles
COI requirements also apply to buses and various other public-passenger vehicle categories.
Trucks, Heavy Trailers & Other Heavy Categories
Many heavy vehicles also fall within the COI system, although where they are inspected can depend on the vehicle category.
Not Every COI Vehicle Is Inspected in the Same Place
Depending on the vehicle type, the inspection may be carried out by an appropriately accredited Approved Inspection Station or through an NHVR inspection centre.
Queensland's booked-hire requirements include having the vehicle appropriately registered and maintaining a current COI unless the vehicle is exempt.
So What Is Each Inspection Actually Doing?
This is where the names can become confusing. Both a Safety Certificate inspection and a COI involve checking whether the vehicle meets applicable minimum safety requirements.
The key difference is the scheme the vehicle falls under and why the certificate is required.
Most commonly connected with a light vehicle being transferred, registered in Queensland or re-registered.
A recurring compliance requirement for vehicles that fall within Queensland's COI categories.
Having one certificate doesn't automatically satisfy a requirement for the other if the vehicle falls into a different inspection category.
Think: Registration & Transfer
For most everyday light vehicles, the Roadworthy/Safety Certificate usually comes into the picture when ownership or registration circumstances change.
Think: Vehicle Category & Ongoing Use
COIs are periodic because certain commercial, passenger and heavy vehicle categories need to maintain current inspection status while being used or registered in that category.
Start With What the Vehicle Is Being Used For
If you're still unsure which inspection applies, these two paths cover the most common situations.
It's a Normal Light Vehicle
You're selling or transferring it, registering it in Queensland or re-registering it, and it doesn't fall within a COI vehicle category.
You're most likely looking for a Queensland Safety Certificate — commonly called a Roadworthy or RWC.
The Vehicle Has a COI Use or Category
It's being used for booked-hire, taxi, limousine or another COI-regulated purpose, or it falls into an applicable heavy/passenger vehicle category.
You're looking for the appropriate Certificate of Inspection.
COIs Are Normally an Ongoing Annual Requirement
Queensland COIs are generally valid for 12 months. Owners of registered COI vehicles need to maintain a current COI unless an exemption applies, and a current COI is required to renew registration for a COI vehicle.
The exact requirement can depend on the vehicle type, weight, seating capacity, registration and purpose of use. If you're not sure, check the vehicle's Queensland requirements before booking.
