Three families will never be the same after tragically losing loved ones this Queen's birthday long weekend.
A cyclist, pedestrian and driver were killed during the four-day police operation with the incidents taking the state's lives lost total to 147, a shocking 55 more than the same time last year.
Speeding topped the list of detected offences, with 3,451 people caught over the limit.
Road Policing Command Assistant Commissioner Stephen Leane said that despite an increase in police enforcement, three lives were still lost over the weekend.
"When comparing to last year's Operation Regal, Victoria Police completed double the amount of drug tests and caught more people both drink driving and speeding," AC Leane said.
"We are doing as much as we can to encourage the community to change their behaviour, but need everyone on board to make a difference on our roads."
The fatalities were:
• An 18-year-old male cyclist was hit by a truck and killed on Friday, 7 June about 12.10pm in Golden Gully.
• A 37-year-old man lost control of his car and crashed into a tree in Jam Jerrup on Saturday, 8 June at approximately 7.40pm.
• A 39-year-old male pedestrian was struck by a vehicle in Mudgegonga on Saturday, 8 June at approximately 11.25pm.
"You cannot begin to imagine how these families are feeling, not to mention the police who had the task of delivering the news," AC Leane said.
"It is frustrating that people still chose to do the wrong thing especially when we hear about the harsh realities of road trauma nearly every day in the media.
"It is as simple as putting the phone down, paying attention to the road and adhering to the speed limit.
On average one in every 22 drivers that were drug tested were found to be under the influence of illicit substances with 204 returning positive results, while 283 motorists were caught drink driving.
"Like alcohol, drugs can reduce a driver's ability to have full control of a vehicle," AC Leane said.
"If you choose to drink or take drugs before driving a vehicle, you will get caught."
