$464 fine threatens drivers who break this bizarre road rule

You might not think that keeping your number plate clean is a high-priority task, but letting it get too dirty could land you in serious trouble.

Believe it or not, it is illegal to have a dirty number plate especially if the dirt and grime make it unreadable for authorities or road-based devices such as speed cameras.

With Australia's dusty roads, swarms of bugs and occasional wet weather all able to quickly make your licence plate dirty, it doesn’t take much for it to become difficult to read. So what could happen if you fail to clean it?

Clear and visible

When you think about it, keeping your number plate clean is a no-brainer. After all, it is the primary way the authorities identify your vehicle no matter if it’s through speed cameras or a police checkpoint.

This is why states across Australia take this rule breach quite seriously.

Most states have made it very clear in their laws about number plates and their visibility. No matter where you are in Australia, you need to ensure that the plate itself is:

  • Visible from 20m away

  • Fixed in an upright position on the front and rear bumper

  • Displayed no higher than 1.3m from the ground

  • Free from any reflectors and tinting that could prevent it from being read by a device

These licensing rules are virtually the same for all cars across Australia no matter what state you are in however, different rules may apply to commercial vehicles, motorbikes and other forms of transport.

An expensive cleaning job

Authorities have taken a tough stance against anyone caught driving with obscured or dirty licence plates anywhere in Australia.

Some states have have introduced heavy fines and issue demerit points to anyone caught breaking laws around keeping your number plates clean. Here are the penalties you will cop for this offence in each state:
