Reported at www.abc.net.au: Only New South Wales, the Australian Capital Territory, and Western Australia implement double demerit penalties during peak traffic periods, with claims of reduced crashes and fatalities during these times.

Academics urge for updated peer-reviewed research, noting a significant lack of recent studies on the effectiveness of double demerit schemes in Australia.

Despite anecdotal evidence suggesting improved road safety during these periods, experts highlight that existing data is insufficient to draw definitive conclusions.
