Refuse Drug Test (Drug Driving)
Published · Updated
In Victoria, Refuse Drug Test – Drug Driving is found in section 49(1)(ca) of the Road Safety Act 1986. It is a criminal offence that is committed by a person who refused to undergo an assessment for drug impairment when required to do so, or who refused to comply with any other requirement made under section 55A(1) of the Road Safety Act 1986. Note that if the Police request that you undergo drug test, you have the option to refuse a drug test. However you can be charged for this. There can be more serious consequences for refusing to do a drug test rather then returning a positive drug test. The Police have significant discretion available to them when requesting for a drug test.
