Number plates

What the plate tells you and what it does not

A plate number is a lookup key. Run it through a vehicle check and you get the record the register holds: make, model, year, basic specifications, licence and inspection status. That is genuinely useful when you are standing in a driveway deciding whether the car in front of you is the car in the advertisement.

What it does not give you is history that lives somewhere else. Money owing sits on the Personal Property Securities Register, which is run by the Companies Office and has nothing to do with the transport agency. Damage and write-off history is a third question again. And crucially, a plate can be changed, so a plate-keyed search only reaches back as far as the current plate. That is why serious checks are done against the VIN, which is stamped into the vehicle and stays with it for life.

When you need new plates

Four situations account for almost all replacements.

Theft. Covered above. Report first, replace second.

Damage and age. Plates corrode, crack, delaminate and fade. A plate that has gone milky or lost its reflective coating is legally a problem even though nothing is missing, because it is no longer readable at night or on camera. If you cannot photograph it from ten paces and read it back, neither can anything else.

Loss. One plate rattles off on a gravel road and is never seen again. A single surviving plate is not a solution.

Reregistration. A vehicle whose registration was cancelled and later brought back onto the register goes through the reregistration process and comes out the other side with plates issued at that point — which may not be the plates it wore before.

Replacement plates covers how the replacement process is arranged and what you need to have with you.

Personalised plates, briefly

A personalised plate is a combination you choose rather than one issued in sequence. It is held as a right you own, and it can be moved between vehicles or held while you are between cars.

Two things surprise people. The first is that a combination can be declined — applications are assessed, and grounds such as offensiveness or resemblance to an official or general-issue format are real. What happens when a personalised plate is rejected sets out the grounds honestly and what recourse you have. The second is that black plates, which most people think of as a vintage look, are a specific style choice with their own limits — black number plates explains what is actually available.

Personalised plates is the place to start if you are considering one.

The rules that get people ticketed

Legibility is the whole standard, and it is enforced against a surprising number of things drivers consider harmless.

Covers and films are the big one. A tinted, smoked or "privacy" plate cover defeats camera reading, which is precisely why they are sold and precisely why they are not allowed. Frames become a problem when they overlap the characters or the border. Bicycle racks and towed loads that obscure the rear plate are the same offence even though nothing has been altered — if the plate cannot be seen, the vehicle is non-compliant while that rack is on.

Positioning matters too. A plate propped inside the rear window, cable-tied at an angle or mounted behind a bull bar is asking for a conversation.

Finally, do not modify the plate itself. Repainting, bending characters to change how they read, adding stickers or screws placed to alter a digit — all of it moves the offence from a fitting problem into deliberate misrepresentation, which is treated far more seriously.

When plates were ordered and nothing came

This is the most common quiet failure in the whole plates system, and it is the one nobody publishes about because it is a logistics gap rather than a rule. You paid, you were told they were coming, and weeks later there is still an empty bracket on the front of the car.

We cannot tell you how long it takes, and anyone quoting you a firm number is guessing. What we can tell you is what to do in the meantime, who to actually chase, and what your position is if you get pulled over while waiting. Plates ordered but not arrived covers exactly that.

If you are buying or selling

When you sell, the general-issue plates go with the vehicle and the buyer notifies the change of ownership. Nothing needs to happen to the plates themselves.

When there is a personalised plate involved, it needs a decision before the sale, not after. Either it goes with the car as part of the deal, or it is removed and retained — but that has to be arranged, and "I assumed it came off automatically" is how people lose combinations they paid thousands for. The same applies when a vehicle is written off or sent to a wrecker: deal with the plate before the vehicle is moved, because recovering one off a crushed shell is not a process that exists.
