How Long Does A Roadworthy Certificate Last In Mackay?

A.M.D. Automotive Services • September 17, 2026

If you’re organising a roadworthy in Mackay for a private vehicle sale, a Queensland safety certificate is generally valid for 2 months or 2,000 km from the date it is issued, whichever comes first. Different validity rules apply when a licensed motor dealer sells the vehicle.


That expiry matters if you’re selling a registered car, transferring registration or dealing with a vehicle that needs to be registered in Queensland. Getting the timing right can help you avoid having to arrange another inspection before the transaction is complete.

What is a safety certificate in Queensland?

A safety certificate is Queensland’s official term for what many drivers still call a roadworthy certificate. It confirms that an approved examiner has inspected the vehicle against Queensland’s minimum safety standards at the time of inspection.


Only an Approved Inspection Station (AIS) can issue a Queensland safety certificate. Depending on the inspection station, the certificate may be issued electronically or in handwritten form.


For a light vehicle, a typical roadworthy inspection checklist covers safety-related areas including:


  • Tyres, wheels and brakes
  • Steering and suspension
  • Seats and restraints
  • Lights and electrical components
  • Windscreen, windows and glazing
  • Body, chassis and frame
  • Engine, driveline and emissions
  • Vehicle safety features
  • Identification and modifications
  • Relevant tow couplings


The inspection can also include a road test and service brake test.



Importantly, a safety certificate is not the same as a comprehensive mechanical inspection. Passing the inspection means the vehicle met the required safety standards when assessed. It does not necessarily tell you about every mechanical issue, upcoming maintenance requirement or the vehicle’s overall condition.


A used car, for instance, may have tyres, brakes and suspension that meet the required safety standards while still having maintenance items that a buyer may want checked separately.

How long does a roadworthy certificate last in QLD?

For most private sellers asking how long does a roadworthy certificate last in Queensland, the answer is 2 months or 2,000 km after issue, whichever comes first.


That “whichever comes first” rule is important.


Say you have a safety certificate issued before advertising your car. You find a buyer six weeks later, but you’ve driven more than 2,000 km since the certificate was issued. Even though two months have not passed, the certificate has exceeded its kilometre limit.


For vehicles being disposed of by licensed motor dealers, the certificate is generally current for 3 months or 1,000 km after issue, whichever comes first.


So, if you’re wondering how long is a roadworthy certificate valid for in Queensland, check both the issue date and the distance travelled since the inspection. Don’t rely on the date alone.


It also makes sense to consider timing before booking your inspection. If you’re preparing for a private sale but won’t be ready to complete the transfer for some time, booking too early could leave you needing another certificate.

Can I use the same certificate for a sale and a re-registration?

You shouldn’t assume one safety certificate can cover multiple registration transactions simply because it remains within its time and kilometre limits.


Queensland Transport and Main Roads describes safety certificates for light vehicles as being issued for a single registration transaction. The Queensland safety certificate form also states that a certificate can only be used once for a sale or transfer, excluding certain transactions between licensed motor dealers.


This distinction can matter if your plans for the vehicle change.


You might initially obtain a certificate as part of sorting out registration and later decide to sell the vehicle. Whether an existing certificate can be used will depend on what transaction it has already been used for and the circumstances involved, rather than simply whether two months have passed.


If you’re re-registering a lapsed vehicle, bringing an interstate vehicle into Queensland or preparing for a sale, it’s worth confirming the certificate requirements for your specific transaction before booking. That can help you avoid paying for an inspection at the wrong stage of the process.

What happens if my car fails the inspection?

Failing a roadworthy inspection doesn’t necessarily mean there is a major problem with the car. It means the examiner has identified one or more defects that prevent the vehicle from meeting the required safety standard at that inspection.


The inspection report should identify the defects that need attention. If you return the vehicle to the same Approved Inspection Station within the applicable 14-day reinspection period, the examiner can reinspect the relevant defects. If the vehicle isn’t returned within that period, a new full inspection is required and another inspection fee may apply.


Issues can involve tyres, brakes, lights, suspension, windscreen condition, seatbelts and other safety-related components. Before booking, it can be useful to read about the common issues that cause a roadworthy failure and check obvious problems beforehand.


Don’t try to guess whether a borderline component will pass. An approved examiner needs to assess the vehicle against the applicable Queensland standards.


If defects are found, A.M.D. Automotive Services Pty Ltd can help you understand what requires attention. Our mechanics in Mackay can assess and repair vehicle issues so you can arrange the required reinspection.

Frequently Asked Questions

  • How long does a roadworthy certificate last in Queensland?

    For a private sale, a Queensland safety certificate is generally current for 2 months or 2,000 km after issue, whichever happens first. For vehicles sold by licensed motor dealers, it is generally 3 months or 1,000 km, whichever happens first.

  • Is a roadworthy certificate the same as a safety certificate in Queensland?

    “Safety certificate” is the official Queensland term, while many drivers use “roadworthy” or “roadworthy certificate” to describe the same inspection certificate. An Approved Inspection Station must inspect the vehicle before a certificate can be issued.

  • Do I need a safety certificate before advertising my car for sale in Queensland?

    No. Queensland no longer requires you to obtain a safety certificate before offering a registered vehicle for sale. However, you generally need a current safety certificate before disposing of a registered vehicle to someone other than a motor dealer.

  • What happens if my Queensland safety certificate expires before I sell the car?

    If the certificate passes its applicable time or kilometre limit before the transaction is completed, you’ll need a new current certificate where one is required. For a private sale, keep track of both the two-month period and the 2,000 km limit.

  • How long do I have to fix a failed roadworthy inspection?

    Queensland’s Approved Inspection Station rules provide a 14-day period for returning a vehicle to the same AIS for reinspection after an inspection report is issued. If you return after that period, a new full inspection is required and another inspection fee may be charged.

  • Where can I get a roadworthy certificate in Mackay?

    Queensland safety certificates can only be issued through an Approved Inspection Station. If you’re preparing your vehicle for a sale, transfer or registration transaction, contact A.M.D. Automotive Services Pty Ltd to arrange a roadworthy inspection and confirm what you’ll need before your appointment.
