Drug driving legislation was introduced in the year 2000 to allow police to test driver’s involved in an accident, for drugs.
In 2003 parliament introduced legislation allow for random saliva testing, the equivalent of random breath tests, for drugs. The bill passed on December 2003. Initially it was rare for drug driving tests to be randomly conducted, but it is now commonplace.
In more recent years the legislation has become tougher to the extent drug driving now attracts mandatory periods of disqualifications off the road, varying depending on whether the person being charged has prior relevant matters.
Prior relevant matters, per section 48(2) of the Road Safety Act include previous drink driving offences. For the purposes of determining the mandatory disqualification period, section 50AA tells us that a matter under section 49 of the Road Safety Act will only be considered a prior matter in circumstances where there was a finding of guilt in relation to that matter 10 years prior to the offence date of the current offence.
More and more people are now being prosecuted for drug driving. Often people are using drugs 24 hours prior to driving and not realising that the drug is remaining in their system.

Drug driving offences are treated seriously in Melbourne, with strict laws designed to deter drivers from operating vehicles under the influence of illicit or prescription drugs. Unlike drink driving, drug driving charges can arise even when a driver does not appear impaired, as roadside saliva tests detect the presence of substances such as cannabis, methamphetamine, and MDMA. A positive result can lead to immediate licence suspension, fines, and a court appearance, making it essential to seek experienced legal advice as early as possible.
