Auxiliary plates

You will need to purchase and affix an auxiliary plate if a bike rack or mobility device is attached to your vehicle and obstructs the view of your rear number plate.

  What are auxiliary plates?

Each character (letters and numbers) of a number plate must be clearly visible when the vehicle is used on the road. If you attach a bike rack or mobility device rack to the rear of your vehicle and it or the load obstructs any character on the number plate from being read, you will need to purchase and affix an auxiliary plate.

Your auxiliary plate will display the same characters as the number plate issued for the vehicle.

On the payment of the required fee, the Department of Transport (DoT), Driver and Vehicle Services (DVS) will provide an auxiliary plate for fitment to bicycle or wheelchair carriers when attached to the rear of a vehicle to assist vehicle owners to meet their obligation to ensure number plate characters can be read whenever the vehicle is used or driven, and to support on road law enforcement.

Auxiliary plates are made of aluminium and have the following dimensions:

  • Motor vehicle plate 253 mm x 99 mm.

  Step 2:Collection of your auxiliary plate

You will receive an email notification advising you that your plate is ready for collection from the DVS centre, regional DoT office or agent you nominated when applying.

You must take the following with you to the Driver and Vehicle Services centre or regional DoT office or agent when you collect your plate:

  • Primary proof of identification.
  • If the plate is not collected within three months of the date of the collection email, the plate will be destroyed and you will have to apply and pay for a new auxiliary plate.

Collection of your new plate by a third party

The vehicle owner may nominate another person to collect auxiliary plates, subject to the following conditions:

  • The person collecting the plate must have proper primary identification, and evidence of your consent.

The vehicle must be currently licensed or within the renewal period (i.e. three months prior to or following the expiry date).

  Fitting auxiliary plates to your vehicle

Screws are not supplied with plates issued by DoT.

You will need to organise the removal of the old plates and attachment of the new plates yourself, or arrange for them to be fitted by a car dealership or garage.

When a bicycle rack, wheelchair carrier or other device is fitted to the towbar of the vehicle and it or the load obscures the visibility of the rear number plate, an auxiliary plate should be securely affixed in an upright position parallel to the vehicle axles, no higher than the vehicle roof line so that it is clearly visible to the rear. Auxiliary plates are manufactured with mounting holes and slots pre-drilled to assist with options to affix the plate to the carrier or load.

What do I do with my auxiliary plate when I am not displaying it on my vehicle?

We suggest you keep your auxiliary plate in a safe and secure location when not in use.

What happens if I lose my auxiliary plate or it is stolen or damaged?

Where an auxiliary plate is lost, stolen or damaged but the existing vehicle number plates are intact you can apply and pay for a new auxiliary plate through your DoTDirect online account.

If the existing vehicle number plates have been lost, stolen or damaged then standard replacement processes apply. Refer to Replace lost/stolen or damaged number plates
