What happens if I have a defect and it doesn’t pass on the first inspection?

Firstly, the Queensland Transport department allows you 14 days from the first inspection date to have any defects repaired.

Secondly, call us on 1300 671 233 when the repairs are completed.  We will come and complete the second inspection.

(Re-Inspection charges apply to mobile services)

The examiner will check those items that failed the first inspection and issue the completed COI.

That is to say these repairs have been completed within the minimum standard set out by the rules within the National Heavy vehicle Regulator.

What do I need to do if my truck is unregistered?

  • You need at least Compulsory Third Party Insurance on the vehicle
  • A copy of the Department of Transport’s New Registration Application Form signed by the owner

How often do I need to have a Certificate of Inspection?

Your vehicle heavy vehicle is required to have a valid Certificate of Inspection every 12 months. 

Moreover, Queensland Transport and Main Roads will send a reminder notice approx. 12 weeks prior.

However, COI’s are a time sensitive Certificate. 

The timing of when to get a COI completed can be confusing. 

Question: What happens when you get your COI issued up to one month before the COI due date?

Answer: The new Certificate will not be allocated to the vehicle until the previous Certificate of Inspection expires.

Question: But what if you get the COI is issued more than a month before the COI due date?

Answer: The new COI due date will become the valid certificate date.

Most importantly, you will need to contact Queensland Transport if you do not complete the inspection on time.

Consequently, you will need to file an application for extension of time.
