Common act while driving could cost you $125 or $2000, depending on one detail

A chime sounds. A driver glances down to read the notification on their smartwatch, then looks back at the road.

It only took a few seconds but that distraction may have doubled the risk of a crash, and could cost Australian drivers hundreds or even thousands of dollars in fines depending on where they're caught.

The problem, according to one expert, is that most Australians have no idea they can be penalised for using a smartwatch while driving.

Smartwatch ownership has boomed in the last decade but there are currently no specific road rules addressing their use while driving.

Instead, drivers may be penalised for using a smartwatch behind the wheel under distracted driving or mobile phone road rules.

But these rules and the penalties associated vary between states and territories.

In South Australia, drivers caught using a smartwatch while driving may face a $125 fine, while in Tasmania fines can exceed $2000.
