A senior Victorian police officer is campaigning to cut the blood-alcohol limit for drivers from 0.05 to 0.02 per cent.

Victoria Police Road Policing Assistant Commissioner Robert Hill says a similar decision in Sweden saw the level of fatalities and serious injuries on the road drop 10 per cent.

He says it is would be a big move but that it is time to consider all options to reduce the road toll.

Mr Hill says 197 people have died on Victorian roads this year and 25 per cent of those deaths are linked to alcohol.

"I want us to reduce the road toll. My thinking is it's all about saving lives," he told ABC local radio.

"I put it in the public domain for the community to do some reflection, some public discourse and for people to think about this."

He says the shift in attitudes has already begun with newly licensed drivers expected to have a zero blood-alcohol level.

In Europe, for example, he says drinking and driving are distinctly separate activities.

"They have just separated the two activities and not through regulation. It's come about by the community shifting and thinking about their social responsibility," he said.

"We've introduced a graduated licence system for our young people. They have accepted that they don't drink and drive. They have adapted to that."

He is also pushing for the wider use of speed cameras but denies it is a revenue-raising exercise.

"It's about saving lives. Speed is the major contributor to road trauma. We lost last year 86 people as a consequence of excessive speed," he said.

"It's that minority group that we need to get off the roads because they're killing people, if not themselves."
