Modification Plates

 

All vehicles modified in Queensland must receive approval for the modifications from the Queensland Department of Transport. This process ensures that modifications have been completed to an acceptable standard ensuring that the modified vehicle will continue to operate safely.

 

To streamline the approval process for vehicle modifications approvals, the Authorised Officer Scheme was introduced.

 

Authorised officers are suitably qualified and experienced persons from private industry who are authorised by the Minister of Transport to issue approvals for certain types of vehicle modifications and to perform certain vehicle certification procedures on behalf of the Queensland Department of Transport.

 

There are two Authorised Officer Schemes, the Commercial Vehicle Modification Scheme and the Light Vehicle Modification Scheme.

 

There are circumstances where modifications are outside of the scope of the guidelines. The process to be considered for approval is to submit the information to Queensland Transport and Main Roads. If the modificaiton is permitted they will issue you with a letter of approval that you can then present to the Modification Plate issuer.
