Many Australians may unknowingly be breaking the law and facing fines exceeding $1,200.

The infraction involves wearing a seatbelt incorrectly by tucking it under the arm while in a moving vehicle.

This practice is prohibited across all states and territories in Australia, and it carries significant fines and demerit points.

As the holiday season nears, the introduction of double demerits will amplify these penalties.

In Australia, it is illegal for both drivers and passengers to wear a seatbelt under their arm, no matter the location.

It is illegal to wear a seatbelt under your arm in all Australian states and territories, regardless of whether you’re the passenger or the driver.

This is because wearing a seatbelt under your arm is considered incorrect seatbelt use.

“Motorists are reminded the lap portion of a seatbelt should lie low, flat and firm over your hips and the sash should be across your chest and mid shoulder – never under the arm,” a Transport for NSW spokesperson told 9news.com.au.

“Too often we are seeing people wearing the seatbelt under their arm, which means an increased risk of death or injury in the event of a crash.”

Wearing a twisted or slack seatbelt is also considered incorrect seatbelt use and may attract penalties.

Fines vary by state and territory, with penalties for an individual not wearing a seatbelt correctly in one state exceeding $1200.

Who gets a fine if the passenger is not wearing a seatbelt?

Both drivers and passengers may be fined if the passenger is not wearing a seatbelt.

Drivers will face fines and demerit points if they’re caught with a passenger of any age not wearing a seatbelt correctly.

Only passengers aged 16 and above will face fines if they’re caught without a seatbelt.

In some states, including NSW and Tasmania, a passenger caught without an appropriately fastened seatbelt can only be fined by a police officer.

Only the driver will receive an infringement notice if the passenger is caught by a seatbelt detection camera.

How do seatbelt detection cameras work?

Seatbelt detection cameras operate alongside mobile phone detection cameras to photograph and identify drivers breaking the law.

Fixed and mobile seatbelt detection cameras snap images of all cars as they pass, including the registration and the front seat of the car.

The images are then reviewed by artificial intelligence (AI) software that automatically detects potential seatbelt offences.

Trained humans then verify that an offence has actually occurred before issuing an infringement notice.

Images that don’t show any potential seatbelt offences are deleted.

Seatbelt detection cameras are currently in use in NSW, Queensland, Victoria, the ACT, WA, and Tasmania.

Are there exemptions for not wearing a seatbelt?

Yes – but only in very rare circumstances.

Drivers with a full licence don’t need to wear a seatbelt when reversing.

Passengers don’t have to wear a seatbelt if they’re giving or receiving urgent and necessary medical treatment.

Drivers and passengers in garbage or delivery vehicles who have to exit regularly also don’t need to wear seatbelts, provided the vehicle is travelling under 25km/h.

Some Australians may also be issued a seatbelt exemption medical certificate by a doctor for a medical condition or disability.

These certificates are valid for limited time periods and must be carried whenever in a vehicle.

Can you dispute a seatbelt fine in Australia?

If you disagree with a fine, you can contact the relevant state or territory revenue office to request a review.

Eligibility criteria and review requirements vary by state and territory.
