In New South Wales, it is illegal to drive under the influence of drugs, including certain prescribed restricted substances. The relevant legislation is the Road Transport Act 2013.
Under the legislation, it is an offence to drive while under the influence of drugs, including both illicit drugs and prescribed medications that impair your ability to drive. The law focuses on impairments rather than specific substances. Therefore, it doesn’t matter whether the substance is legal or illegal; if it affects your ability to drive safely, it is considered an offence.
If you are caught driving under the influence of drugs, you may face penalties that can include fines, licence suspension or disqualification, and in some cases, imprisonment. The specific penalties depend on factors such as the type of drug detected, your blood concentration level, previous offences, and other circumstances.
