Almost 300 police officers a year are booked for speeding while on the job, without any evidence they are responding to an emergency.
The figure is just under half of the 608 working police staff caught speeding during the financial year to June 30, 2008.
In all 278 of the cases where there was no evidence they were responding to an emergency, officers were made to pay fines.
The previous year, 260 speeding tickets required payment by the officer responsible.
Both years, speeding police cars were snapped most by mobile speed cameras.
In 2007-08, mobile cameras caught 450 speeding on-duty police officers.
Of those, 227 tickets were waived.
By comparison, only 48 of the 158 tickets issued by fixed cameras were required to be paid by officers.
The officers were required to pay the fines and lose demerit points, as did any other motorist breaking the law.
A police spokesman said the the number of tickets issued to police staff needed to be balanced against the 92 million km driven every year by the police fleet of 3311 marked and unmarked vehicles.
