Police detected more than 6,300 traffic offences and more than 740 crime offences during the four days of Operation Amity over the Australia Day long weekend.

There were also three deaths on regional Victorian roads during this time.

Road Policing Command Acting Assistant Commissioner Glenn Weir said the results were incredibly disappointing for police.

"Sadly, three families are now mourning the loss of a loved one due to fatalities on our roads," A/AC Weir said.

"These tragic deaths coupled with the results from Operation Amity are very concerning to police.

"Over the long weekend we saw far too many people making dangerous and illegal choices by getting behind the wheel when they were either drug or alcohol affected.

"One in every 10 drivers tested furnished a positive result for drugs while 254 drink drivers were caught after more than 106,040 drivers were tested."

The lives lost on the roads over the operation occurred when:

  • a 24-year-old woman died after the car she was a passenger in left the road and crashed into a tree in Halls Gap on Saturday 27 January.

  • a man, who is yet to be identified, died after his motorcycle left the road and slid down a hill in Mount Buller on Sunday 28 January and

  • a 44-year-old woman died after the car she was driving crashed into a tree in Toolern Vale on Sunday 28 January.

Across the state, Operation Amity detected:

  • 166 disqualified/suspended drivers
  • 224 unlicensed drivers
  • 569 unregistered vehicles
  • 2396 speeding offences
  • 239 mobile phone offences
  • 421 disobey sign/signal offences
  • 206 seat belt offences
  • 59 vehicles impounded

The four day operation over the Australia day long weekend started on Thursday 25 January and concluded at 11.59pm on Sunday night.
