Vehicle modifications

If you have built or modified your vehicle, it may have to be assessed by the technical advisory committee (TAC).

The committee provides recommendation to the MVR on the approval and suitability of your vehicle.

It is made up of representatives from various motor vehicle enthusiast groups, transport department officers and NT Police.

You will need all of the following:

• your vehicle details such as the month and year of vehicle manufacture
• additional information that will help in the assessment of your vehicle such as:
  • photos or sketches
  • certification documents such as engineering approval or kit approvals.
• a signed representative authorisation form, or similar level of authorisation evidence, such as an email or letter, if applying on behalf of the vehicle owner.
