Premier Gladys Berejiklian's new road safety plan will crack down on speeding, drink- and drug-driving, driver distraction and fatigue to make NSW roads safer.
Cameras will be used to catch NSW drivers using their phones under a government plan to improve safety after the most deadly 12 months on the state's roads in almost a decade.
Some 392 people died on NSW roads in 2017, the highest figure since 2010, prompting Premier Gladys Berejiklian to announce a range of tough new road safety measures on Tuesday.
Laws would be amended so cameras can be used to spot drivers on their phones, while people convicted of mid-range drink-driving would be forced to use alcohol-testing devices built into their vehicles.
The state government would also introduce 11 more heavy-vehicle average speed camera locations in Sydney.
"All of us across the state have been touched by the heartbreak when unnecessary lives are lost on our roads," Ms Berejiklian told reporters.
The premier said the government would also spend another $125 million on safety barriers and rumble strips throughout the state.
An inter-agency working group was assessing whether people should be allowed to drive while using prescription drugs.
That move came after the Falkholt family - including Home and Away actress Jessica - died following a horror Boxing Day crash on the NSW south coast.
The driver of the four-wheel drive which slammed into their car - who had a shocking driving history - was on his way home from a Nowra methadone clinic when the accident occurred.
"We know that drugs which people are prescribed can affect their ability to drive and we have experts in health and justice coming together to give government advice if there's anything further we need to do," Ms Berejiklian said.
NSW Police would also be given the power to issue on-the-spot fines and licence suspensions for low-range drink-driving.
NRMA spokesman Peter Khoury said the public wants action tough action to reduce the escalating road toll.
"Last year was a horrible year, this year is demonstrably worse," he said on Tuesday.
