Drink Driving

Types of Offences

If you’ve been charged with a drink driving offence, it’s important to understand what the law is and where you stand.

In South Australia, there are three different types of alcohol-related driving offences:

  • Driving under the influence (DUI).
  • Driving with a prescribed concentration of alcohol (PCA).
  • Failing/refusing to blow (refusing to comply with directions in relation to breath analysis).

Each offence and alcohol reading carries different penalties.


A person can be charged with DUI when they are driving or attempting to drive a motor vehicle and they are under the influence of drugs or alcohol. They must be incapable of effectively controlling the vehicle.

A person can be charged with driving a motor vehicle, or attempting to drive a motor vehicle, with a PCA of 0.05 present in their blood (or 0.00 for a probationary driver).

Failing or refusing to blow

Failing or refusing to give a breath test is an offence. For more information, click here.

If you’ve been charged with any of these offences, it’s important that you get legal advice as soon as possible. This is the best way to try and minimise any impact that the charges may have on you.
