Frequently Asked Questions

  • What is a vehicle modification plate in Queensland?

    A vehicle modification plate, also known as a mod plate, is a certification issued by an approved examiner in Queensland. It confirms that any modifications made to a vehicle meet safety and legal standards. Without a mod plate, certain vehicle alterations can make your car unroadworthy or illegal to register and drive on public roads.

  • Which car modifications require a mod plate in QLD?

    Mod plates are required for structural or performance-related modifications, such as engine upgrades, turbo or supercharger installs, suspension lifts, transmission changes, and seating capacity alterations.

    If a modification affects how your vehicle performs or handles, it likely needs certification. It's best to check with an approved certifier before starting any major work.

  • How do I get a mod plate for my car in QLD?

    To get a mod plate, you’ll need to have your vehicle inspected by an authorised examiner who will assess whether the modification complies with Queensland’s Vehicle Modification Framework.


    If it passes, they’ll issue a plate and update the records. The process also involves paperwork, so it's important to ensure all parts and work meet approved standards.
