Police say NSW drivers are ignoring the message not to text and drive, after a statewide traffic blitz on Wednesday resulted in more than 1200 infringements being issued for illegal phone use.

The operation, which targeted dangerous driver behaviour across NSW, also saw 137 infringements handed out for not keeping left, and 586 infringements for defective vehicles.

Drivers caught using their phones face a $330 fine and the loss of four demerit points, but NSW Traffic & Highway Patrol Commander, Assistant Commissioner Michael Corboy, says motorists appear undeterred.

"Despite the numerous warnings and obvious dangers to drivers and innocent road users, the message not to text and drive is just not getting through," he said in a statement.
