Driving under the influence

Under section 47 of the Road Traffic Act 1961, a person commits an offence if they  are under the influence of alcohol to the point of not being capable of exercising effective control of the vehicle. A person will be found to have been incapable of exercising proper control of a vehicle if any of their physical or mental faculties is appreciably impaired.

A person found guilty of driving a motor vehicle while under the influence (DUI) is subject to the following penalties:

  • For a first offence, a fine of between $1100 and $1600 or imprisonment for up to three months
  • For a subsequent offence, a fine of between $1900 and $2900 or imprisonment for up to six months.

If a person is found guilty of driving a motor vehicle while under the influence, they will be disqualified from driving for at least 12 months. If a person is found guilty of a second DUI offence, they will be disqualified for at least three years.

A person found guilty of driving a vehicle that is not a motor vehicle while under the influence – such as a bicycle or animal-drawn vehicle – can be fined $500.
