Details of the government's $1.3 billion dollar road policing investment programme have been revealed.

It includes new targets for roadside breath and drug tests.

Police are expected to carry out 3.3 million breath tests per year.

65% of those have to be done in high risk areas or during high risk times.

$72 million of the funding will be put aside as a performance incentive.

Police won't receive the money unless they meet the targets.

Police Association President Chris Cahill told Ryan Bridge police currently have a target of around 3 million, which they've only hit twice in the last 10 years.
