Fifteen people have died on central Victoria's roads this year, two more than the total for 2018.
Bendigo Highway patrol Senior Sergeant Ian Brooks said of the five people had died on central Victorian roads in the last month - four of the deaths were preventable.
"From what I understand of those investigations so far, four of those people should not have died if laws were obeyed or there was better driving from all parties involved in those collisions," he said.
Two crashes occurred in the region at the weekend with a 22-year-old Junortoun man dying after a crash on McCrae Street.
"Police are still conducting investigations (into the McCrae Street incident) and following up on information from the public regarding the crash," Senior Sergeant Brooks said.
A teenager who was involved in a crash at Bung Bong, near Maryborough, remains in a critical-but-stable condition at The Alfred.
It is a disregard for rules and the safety of everyone else on the road.- Senior Sergeant Ian Brooks
Senior Sergeant Brooks said the central Victorian division includes Campaspe, Central Goldfields, Greater Bendigo, Mount Alexander, Loddon and Macedon Ranges areas.
He said a majority of crashes that resulted in serious injuries or worse were the result of people disobeying road rules.
"It is a disregard for rules and the safety of everyone else on the road," he said.
"Of those six shires, 15 deaths were on our roads for first six months of the year. For the entirety of last year there were 13. We're already two in front (of last year) with still six months to go in 2019.
"I'm not pointing at any particular collision, we see all the data of crashes of a serious or worse nature and the data tells me people are ignoring road rules. Rules that are put in place to make driving safer."
There have been 156 lives lost on Victorian roads this year. At the same time last year the road toll stood at 100.
Senior Sergeant Brooks said he doesn't know what more can be done to get the message of road safety through to people.
"We're doing our damnedest to bring (the road toll) under control but we don't know how we can do that without the community's help," Senior Sergeant Brooks said.
"The amount (of crashes) we're investigating, if the pattern continues, the road toll will remain high."
