The Calgary police service is trying to encourage better driving behaviour among its own officers.

The police service has audited its photo radar program to make sure officers are driving safely.

On Tuesday night, the results were presented to the Calgary Police Commission, the civilian body that oversees the police service.

From 2010 to 2014, the number of police vehicles caught speeding declined by 68 per cent.

Police Chief Roger Chaffin says that is an indication that internal monitoring is working and officers are improving their behaviour.

"It shows you that, as soon as you pay attention to it, you can change behaviour," he said. "I'm quite satisfied that we're certainly deep into the right track here."

In 2014, roughly 1,500 police vehicles were caught speeding.

The police service says that number will likely never drop to zero, since it includes officers who are responding to high priority calls with lights and sirens.

"Accountability for our officers' performance is important to me," Chaffin said.

"It's very important to the community as well, so as we start to learn more through technologies about what goes on a day-to-day basis, it's then incumbent upon us to make sure that those accountabilities are held to."

Refresher course on safe driving coming

CPS recently spent $35,000 for an online course titled "Preventing Officer-Involved Collisions (for Police)" that will be introduced this year as a mandatory annual refresher training for all officers.

Chaffin says the force also has an internal demerit system to ensure its officers are following the rules of the road.

"Everything is about … there's a rule of law that we follow, that we expect our community to follow and I expect our officers to follow," he said.

"Those demerits help us change behaviour, help us make sure that those officers understand what's expected of them, what I expect of them. And we can measure those things now."
