That is why the ACT Party supports the amendment proposed by the Greens member the Hon Julie Anne Genter to include a review date in this legislation. After about three years of operation, when the police will have conducted what I understand will be thousands and thousands of roadside tests, they will have started to develop an evidence base from which to determine: are fewer people are driving under the influence and coming to harm or harming others? Are we detecting far more people than we thought above what's called the "threshold levels", and, if so, what else do we need to do to intervene peoples' lives in a way that minimises the risk to themselves and others from consuming these substances and then driving their motor vehicles? That is why the ACT Party supports the amendment to include a review of the legislation and its operation performance after three years.
