Anyone caught drink- or drug-driving in NSW will immediately lose their licence for three months under a tough new regime.
First-time low-range drink-drivers will be slapped with an on the spot three-month licence suspension and ordered to pay a $561 fine from May 20.
Drivers found with drugs in their system will face the same sanction if the offence is confirmed by laboratory analysis.
Currently, only those who have a blood alcohol concentration of 0.08 or higher cop an immediate licence suspension.
The NSW change mimics that introduced to Victoria in April 2018.
NSW Police said the drink-driving limit has been 0.05 for almost four decades and drivers have "no more excuses".
"For the last 38 years we have been sending that message clearly, so this is not new," Assistant Commissioner Michael Corboy told reporters in Sydney on Monday.
"You know how much you've had to drink. Make some decisions when you're drinking about not driving, make some decisions about not taking drugs and driving."
He said NSW drivers should be able to travel the state's roads without worrying about being hit by a drunk- or drug-driver
NSW's peak motoring body said two-thirds of its surveyed members supported the immediate licence suspension for low-range drink drivers.
"Only one-in-five opposed it, which is a pretty clear indication the community wants and expects more to be done around this behaviour," NRMA spokesman Peter Khoury told AAP.
Roads Minister Andrew Constance said it was concerning that 56 per cent of low-range drink driving offenders who take their case to court escape without conviction.
Drivers under the new regime can still take their case to court but face a bigger fine and longer suspension.
Mr Constance wouldn't say if he'd consider similarly harsh measures for those caught using their mobile phones behind the wheel but said road safety measures were constantly reviewed.
Some 68 people died in alcohol-related crashes in NSW last year while preliminary results suggest another 70 died in crashes where one or more drivers had illicit drugs in their system.
