Four people, including a four-year-old boy, have died in separate crashes on Victorian roads in less than nine hours.
Brax Aidan Kyle was killed on Friday after he was struck by an out-of-control 4WD as he and his father left Epworth Specialist Centre in Berwick.
Police on Saturday said they are yet to interview the 56-year-old driver.
Two men were also killed in separate crashes in Goornong and Alexandra on Friday, and a pedestrian was killed after he was hit by a 4WD in Shepparton on Friday evening.
Police say 23 people have died on Victorian roads in April, compared to 17 during the same period last year.
"Every loss is a terrible reminder that the risk on our roads never goes away," Assistant Commissioner Doug Fryer said.
With many people likely to take a long weekend over the upcoming Anzac Day period, police want motorists, cyclists and pedestrians to be safe.
"Road trauma doesn't discriminate - cyclists, pedestrians, passengers, drivers and motorcyclists need to share the roads and look out for one another," Mr Fryer said.
Victoria Police is also continuing a state-wide operation aimed at reducing road risks and increasing awareness.
Since April 13 - the Thursday before the Easter long weekend - police have made the following detections:
- 530 mobile phone offences
- 4621 speeding offences
- 204 drug driving offences
- 271 drink driving offences
The operation will run until 2359 hours on April 25.
