VICTORIA Police has trained officers from several one-member Grampians and Wimmera police stations to do roadside tests, as efforts to catch drug drivers ramp up.
On Monday, the force announced the program had expanded to Harrow, Edenhope and Lake Bolac.
Wycheproof, Manangatang and Stanhope police stations are also taking part in the trial, expected to last until March 30.
In a statement, police said until this point roadside drug testing has only been led by specialist units.
Western region Superintendent Peter Greaney said there was opportunity to reallocate a number of drug tests to the one-person stations.
"We were extremely keen to be part of this trial," Supt Greaney said.
"Regional areas across Victoria unfortunately tend to be over-represented when it comes to serious injury and fatal collisions, and the sad reality is that drugs and alcohol are often underlying factors.
"We welcome any opportunity to bring down the severity and incidence of road trauma - particularly heading into Christmas and the New Year - as we know it not only devastates families, friends and loved ones, but creates a huge ripple effect within our communities.
"If this expansion means more police officers can help take even one drug driver off our roads, that's already a huge win for our region."
The Transport Accident Commission states that 'in the last five years approximately 41 per cent of all drivers and motorcyclists killed in Victoria who were tested had illicit and prescription drugs in their system, with cannabis and stimulants the most common substances detected.'
Police said the trial may be expanded to last longer, and to other areas, depending on the results.
Edenhope Leading Senior Constable Darren Ferluga said his sergeant Andrew North and Harrow's Leading Senior Constable Alan Perry were the two members that
"They're both ex-highway patrol so they done the training before," he said.
