Broadly speaking, the bill establishes a new random roadside oral fluid testing regime to deter drivers. The way it works is by providing officers with the power to administer that oral fluid test. A person who is asked by an officer to complete that test will do so and they will then be asked to complete it a second time if the first test shows that drugs may have been used by the person who was driving. This is about building as much robustness into the result as possible. It is important to note that a person who tests positive after two oral tests is only liable for an infringement offence, not a criminal offence. At that point in the process, under the legislation, the person themselves may elect to go down the route of receiving a determinative blood test, and it is only in the event that that blood test produces a positive result that the person may face a criminal penalty if they exceed the criminal thresholds that are set out in the Act.
