Drink Driving Offences in Western Australia


A person who is charged with drink driving in Western Australia will receive either an infringement with demerit points, or a notice to appear in the Magistrates Court, where a penalty will be imposed. In WA, infringements are only issued to those who record a BAC of 0.05 to 0.079, and those who are on a zero limit and record a BAC of less than 0.02. All other drink driving offences require the offender to attend court and be sentenced by a Magistrate who will issue them with a fine and a period of licence disqualification.

If a person has a BAC reading of 0.08 or higher, they will receive an automatic disqualification until their matter is dealt with in court. A zero-alcohol limit is required for all novice drivers, holders of extraordinary licences, recently disqualified drivers, and taxi, bus and heavy vehicle drivers.

The Road Traffic Act 1974 governs the different drink driving offences and associated penalties in Western Australia.

Penalties For Second And Third Or Subsequent Drink Driving Offences

All second and subsequent charges of drink driving in Western Australia will require the accused to appear in the Magistrates Court.

The magistrate can also order a term of imprisonment of up to nine months for a second drink driving offence with a BAC of 0.15 or higher and of 18 months for a third or subsequent drink driving offence with a BAC of 0.15 or higher.

For second, third or subsequent drink driving offences committed within five years of the first offence, the court is required to impose an alcohol interlock order on the driver. The driver must bear all costs associated with complying with this order.
