The changes will be rolled out over the next 12 months and will bring NSW in line with other states and territories.
“No warnings signs mean you can be caught anywhere, anytime and we want that same culture around mobile speed cameras,” Minister for Transport and Roads Andrew Constance said.
Studies from Monash University Accident Research Centre showed removing mobile speed camera warnings could save between 34 and 43 lives, and prevent around 600 serious injuries on NSW roads every year.
Speeding was responsible for 136 deaths and 2941 injuries on NSW roads last year.
The changes particularly target country drivers. Deaths on country roads made up two-thirds of the state’s road death toll last year, with speeding being the biggest killer.
“To see so many lives lost on country roads, where the impacts are felt across entire communities, is devastating,” Minister for Regional Transport and Roads Paul Toole said.
Already this year, speed cameras have generated over $65 million in revenue for the NSW government.
Mr Toole said the money generated from the mobile speed camera program is expected to fund other road safety initiatives.
