Close to 900 drivers were caught talking on their mobile phones on NSW roads during a one-day crackdown on dangerous driving practices across the state.

As part of Wednesday's Operation Compliance, police caught a total 1875 motorists breaking road rules.

Of those, 895 drivers were booked for using their mobile phones, while 414 were caught speeding in school zones.

Another 48 were fined for Children's Crossing offences, while 273 were reprimanded for not wearing a seatbelt.

"Every life lost on our roads is a tragic waste which is why record numbers of police are on our roads every day seeking out motorists who are putting their safety, the safety of the passengers and the safety of others at risk," Police Minister Michael Daley said in a statement on Friday.

"That's why we all have a responsibility to drive as safely as possible every time we get behind the wheel."
