The ACT Government is considering reducing speed limits in high-risk school zones from 40 to 30 kilometres per hour, as part of a new set of initiatives to improve road safety around schools.

Last year over 1,372 infringement notices or cautions were handed out to Canberrans driving in school zones.

Minister for Education and Police, Joy Burch, said reducing the speed limit was being considered as police begin a blitz targeting speeding and dangerous parking around schools.

"When you look at nearly 1,400 precautions and infringements every year, that is far too many," Ms Burch said.

"Each one of those precautions or infringements has put one of our young at risk and that is just unacceptable in this community."

ACT Chief Police Officer Rudi Lammers said one of the worst cases this year was a man found driving at 102 kilometres per hour in a 40 kilometre zone.

Assistant Commissioner Lammers said it would have taken the driver up to 130 metres to stop the car at that speed.

"If he'd have hit a child he would have more than likely killed him," he said.

"At that speed, he would've hit the child at four times the impact had he been driving 40 kilometres an hour."

Chief Minister pledges clearer signage near schools

ACT Chief Minister Andrew Barr said the Government would also trial clearer signage around schools.

"We want to be assured that through our signage both on the roads and the street signs that we are appropriately warning people that they are entering into school zones," Mr Barr said.

"The general message overall is that people need to slow down."

Following its success in New South Wales, zig-zag markings known as dragon's teeth will be trialled to make school zones clearer to drivers.

"What we've seen is that the school signs are often unseen if you're in an unfamiliar area, but if you're driving on a road with markings, there's no excuse - you will see that," Ms Burch said.

"If there's one message, it is about speed, it is about safety, that is the first thing that a driver sees coming up to a school area."

Assistant Commissioner Lammers said ACT police would be providing high-visibility policing around Canberra schools for the rest of the year.

He said police would concentrate on particular on schools with high volumes of cars.

"We're asking parents to be particularly conscious about dropping their kids off at school, parking safely, and not speeding through school zones," Assistant Commissioner Lammers said.

"Even if they don't have children at school, watch the signage, make sure you reduce the speed to at least 40 kilometres an hour and less if necessary to prevent running over one of our children."

The current limit of 40 kilometres per hour is in line with most other states and territories, although South Australia's school zones have limits of 25 kilometres per hour in their school zones.

The ACT Government is seeking the public's views on the proposed measures.
