From today, motorists caught by fixed and transportable mobile device detection cameras using mobile devices will be fined $514 and cop three demerit points.

Police will also continue issuing infringements for driver mobile distraction.

The ACT government says motorists detected from Tuesday using their mobile device while driving can expect to receive an infringement notice by early March.

The start of infringements follows a three-month warning period which saw cameras detect more than 18,000 Canberrans using their mobile device while driving.

Since the introduction of mobile device detection cameras across Canberra in February 2023, more than 63,000 drivers have been detected using mobile devices while driving.
