Drivers will be forced to pass a breathalyser test before leaving a public car park under a state government trial starting next year.

The alco-gates, which involve alcohol sensors linked the exit boom gates, were announced under the road safety strategy and action plan publicly released last week.

The TAC secured budget funding for the trial set to start next year, with locations to be determined in consultation with councils.

Sweden has introduced similar technology that forces drivers to blow into a breathalyser when they arrive at a gate.

If a driver blows over the legal alcohol limit, police nearby are notified.

The Victorian trial is part of the state government's Towards Zero strategy to reduce the road trauma and deaths.

Roads Minister Luke Donnellan said the Andrews Government would invest $1 billion to implement the strategy, which aims to reduce annual road fatalities to 200 or less by 2020.
