Official documents show hundreds of police officers are being caught speeding on the job every year.
Figures obtained under the Official Information Act show that in the five years to 2009, an average of about 570 police vehicles a year were caught on speed cameras exceeding the speed limit.
In four of those years, between 40% and 47% of fines were not waived, meaning the officers who incurred the fine had to pay because they had no justifiable reason to speed.
The Automobile Association says while it's good police are being held accountable for their speeding, the percentage of unneccessary tickets has remained at a relatively high level.
The Police Association says if anyone who's caught speeding can't justify it, including police officers, they have to pay the fine.
