Between January 1 and May 1 this year, Creswick police issued 72 infringements, 43 more than this time last year.

Sergeant Damian Jones of Creswick Police said that most offenders were caught on the Midland Highway between Creswick and Ballarat.

"They are mostly transport people who aren't paying attention to the speed zones," he said. "The majority are in 100kmh zones and 60kmh zones. Luttet St (in Creswick) is a problem area."

He said a female driver was caught exceeding the speed limit by 38kmh on the Midland Highway coming from Ballarat.

"Quite a few have lost their licence for a month. Their general reaction when caught is that they know they were in the wrong and will cop a penalty," he said.

Creswick Police have a new mobile radar that records speeds while the police car is up to two kilometres away from oncoming cars.

The device is used on the Ballarat-Daylesford Rd, the Clunes-Creswick Rd, the Midland Highway and Gillies St, Ballarat, while hand-held radars were used on Albert and Napier streets.

"People have no warning. They can't flash their lights at each other," he said.

"We've had the radar for four weeks and six people have lost their licence. People are slowing down."

Sgt Jones said there hadn't been a fatal accident since December 2004, which was on the Midland Hwy in Newlyn.

"We are keen to maintain that record and basically target main roads," he said.

"We are concerned about fatalities and serious accidents and hope people see us on the roads and slow down."

Trentham Police issue at least one infringement a day on the Daylesford-Trentham Rd.

Senior Constable Geoff Shaw said this wasn't surprising for a country road.

"It varies from week to week and it's a mix of locals and visitors. Some people get too comfortable with their speed and adapt it to the road conditions," he said.

"It's not about raising revenue. Our main concern is (preventing) a serious accident, which has huge implications for the community."

* Creswick Police are on the lookout for people using hand-held mobile phones while driving and people not wearing seatbelts. A Look Lock and Leave program hopes to encourage people to lock their cars.
