Four people killed in horror three days on south-west Victorian roads

Police are asking drivers to take extra care after four people were killed during a horror few days on the roads in Victoria's south-west.

It means that one-quarter of the 16 road deaths which have occurred in the region this year, happened over the space of just 60 hours.

A 20-year-old Warrnambool man died when the car he was driving rolled at Caramut, north of Warrnambool, on Sunday afternoon.

Just seven hours earlier and about 60 kilometres inland, a woman who has yet to be formally identified died in a head-on collision on the Glenelg Highway near Woorndoo-Streatham Road.

A 67-year-old Moama man who was the driver and sole occupant of the other car was taken to hospital with non-life-threatening injuries.

The two deaths came in the wake of a tragedy at Tower Hill on Friday which saw an elderly couple killed in their bedroom when a truck veered off the Princes Highway into their home.

The driver and sole occupant of the truck, a 70-year-old man from Portland in western Victoria, was taken to Warrnambool Hospital with non-life-threatening injuries and has since been released from police custody.

Investigations into all three fatal accidents are ongoing.

A traumatic time

The fatalities are just part of the picture, with at least three other car accidents occurring on roads in and around Warrnambool since Thursday, including a single vehicle rollover on Penshurst-Warrnambool Road and two multi-car collisions on Raglan Parade on Thursday and Saturday respectively.

Warrnambool Police road safety manager Senior Sergeant Kelli Parkinson said it had been a traumatic few days on the region's roads.

"Our hearts go out to everybody that's involved in any of these incidents," Senior Sergeant Parkinson said.

"It's a really, really difficult time for many people."

Senior Sergeant Parkinson urged motorists to drive to the road conditions and take extra precautions.

"Everyone's aware that the roads aren't in great conditions in some areas, but on many occasions where we see serious injuries or fatal collisions occur, the road condition at that point in the roads aren't the causation of the incident," she said.

"A lot of the time it is human error ... these incidents can be prevented just by people taking more attention, driving to the conditions, not being distracted and all those things that are relevant to everyone all the time."

It brings the state's road toll to 229 lives lost so far this year.

This time last year, 236 people had died on Victorian roads, with 133 of those occurring in the regions.

So far this year, 16 lives have been lost on roads in the Barwon South West region, compared to 27 at this time last year.
