Registering an unregistered vehicle, trailer or motor bike

Before driving a vehicle, trailer or motor bike on the road it must be registered and have compulsory third party insurance. Unregistered vehicles, trailers or motor bikes are not allowed to be used or stand on the road and they can be detected by traffic cameras.

Before you begin

You will need to provide:

  • your name, address and date of birth
  • your licence or client number
  • name and address of the person you bought the vehicle from
  • vehicle registration (plate) number
  • engine number
  • vehicle identification number (VIN) or chassis number
  • vehicle make, type and year of manufacture.

How to register an unregistered vehicle, trailer or motor bike in your name

1. Application form

Download and complete a MR1 Application for registration and third party insurance 1.9 MB.

You may need to complete and submit a MR80 vehicle supplementary details form 817.9 KB if you are applying to register or modify:

  • a vehicle that has an unladen mass of 2000 kg or more
  • a vehicle or trailer with a GVM/GTM exceeding 4500 kg.

2. Lodging the form

Return the completed application to a Service SA customer service centre.

If you live more than 100 kilometres from a Service SA customer service centre you can lodge and pay for the initial registration at your nearest police station. Residents of Ceduna, Coober Pedy and Kingscote can go to Australia Post.

The fee to register your vehicle, trailer or motor bike can be calculated by using the EzyReg general fee enquiry.

After you pay the fee a registration details certificate will be issued to you or sent in the mail.

Detecting unregistered vehicles, trailers or motor bikes

Traffic cameras can detect unregistered vehicles, trailers or motor bikes to ensure that everyone contributes towards ongoing road maintenance and upgrades that are funded by registration fees and has compulsory third party insurance.

Fines for unregistered and uninsured vehicles, trailers and motor bikes apply. Make sure you are not caught out:
