Drivers using mobile phone are now in the sights of the NSW government.
It will spend $88 million rolling out fixed and portable cameras across the state to detect motorists using phones.
The cameras will operate 24 hours a day and - unlike speed cameras - there will be no warning signs to alert drivers as they approach.
The high-definition cameras use artificial intelligence to spot drivers using their phones, regardless of the weather or time of day.
It follows a six-month trial of three cameras which recorded more than 100,000 drivers in 85 million car movements using their phones illegally.
For the first three months of the crackdown, errant drivers will simply receive a warning letter but after that, it will be a $344 fine and five demerit points.
The cameras are expected to be rolled out by December.
