On average 490 speeding fines have been handed out each month this year, up from an average of about 337 a month for the past three years.

Officer-in-Charge of Road Policing Detective Inspector Marcus Boorman said police were taking a zero-tolerance approach.

"I've spoken a lot this year about how Canberra's roads are not a race track," he said.

"We are still detecting high-range speeding drivers at speeds that go beyond stupidity. I'm talking about 140, 170, even 200 kilometres an hour.

"It's dangerous for everybody, it's a threat to the community's safety, and we're about to go on the front foot after drivers who use too much of their right foot."

Police have conducted several operations targeting speeding this year due to the rising number of infringements.

ACT Policing will focus on speeding throughout July and run several dedicated operational days targeting motorists.
