Drivers who falsely claim someone else was behind the wheel at the time of an offence could be slapped with an $11,000 fine under harsh new penalties introduced in NSW parliament on Tuesday.

The new legislation doubles the maximum fines for vehicle owners who shirk a penalty for speed camera and other camera-detected traffic offences by falsely nominating another driver.
