Drink Driving in South Australia — What You Need to Know Right Now
Do You Need a Lawyer?
Yes — and the higher your BAC reading or the more complex your situation, the more urgent that need becomes. Here is the honest truth about what is at stake in South Australia.
If your BAC was between 0.05 and 0.079 and this is a first offence, you may receive an expiation notice (an on-the-spot fine) rather than a court summons — but if you are contesting it or it has already gone to court, legal advice is still important. If your BAC was 0.08 or above, you are facing a criminal charge in the Magistrates Court, a mandatory licence disqualification, and the possibility of a fine or even imprisonment depending on the severity.
For high-range readings (0.15 and above), second or subsequent offences, or charges involving an accident, injury, or a child passenger, the consequences become significantly more serious. South Australian courts have mandatory minimum disqualification periods that a magistrate cannot reduce below, no matter how sympathetic your circumstances. A lawyer can help you present mitigating factors, potentially negotiate charges, and ensure you aren't disqualified for longer than the legal minimum.
Without a lawyer, you may unknowingly plead guilty in a way that maximises your penalty, miss a valid defence such as a procedural error in how the breath test was administered, or fail to apply for a restricted licence or hardship licence where you may be eligible. These are mistakes you cannot undo after sentencing. Call 1800 951 176 now.
The Law in South Australia
Drink driving in South Australia is primarily governed by the Road Traffic Act 1961 (SA) and associated regulations, with licence consequences flowing through the Motor Vehicles Act 1959 (SA). South Australia uses a tiered BAC offence system that determines both the severity of the charge and the mandatory penalties that follow.
For fully licenced drivers, it is an offence to drive with a BAC of 0.05 or above. For learner drivers, probationary licence holders (including P1 and P2), and certain professional drivers operating heavy vehicles or public passenger vehicles, the limit is 0.00. There is also a drug driving framework under the same Act, with penalties mirroring those for alcohol offences.
BAC offence categories in South Australia run broadly as follows: low range (0.05–0.079), mid range (0.08–0.149), and high range (0.15 and above). Each category carries escalating minimum disqualification periods and fines. Critically, South Australian law imposes mandatory licence disqualifications — these are not discretionary. The Magistrates Court of South Australia (with its principal registry at the Adelaide Magistrates Court on Angas Street, Adelaide) hears virtually all drink driving matters as summary offences.
If you were breath tested roadside, police use an approved roadside screening device. A positive result leads to an evidential breath analysis at a police station using an approved instrument — typically the Draeger Alcotest. This reading is the one used as evidence in court. There are strict procedural requirements around how this test must be conducted, and breaches can sometimes provide a defence.
Upon a finding of guilt, the Magistrates Court must impose a disqualification period no less than the mandatory minimum set out in the Road Traffic Act 1961 (SA). For repeat offenders, mandatory alcohol interlock conditions may also apply under the Motor Vehicles Act 1959 (SA), requiring an interlock device to be fitted to any vehicle you drive before your licence is reinstated.

What Happens Next — Step by Step
1
Step 1 — Call Legal Hotline immediately on 1800 951 176: Before you do anything else, speak to a lawyer who understands South Australian drink driving law. Free, 24/7, confidential. Do this tonight if you've just been charged.
2
Step 2 — Locate and read all paperwork: Find your Notice to Appear, charge sheet, or summons. Note your court date, the specific charge, your recorded BAC, and the police station or officer involved. Do not lose this paperwork.
3
Step 3 — Do not drive while your licence is suspended: If police suspended your licence at the roadside or station (common for readings of 0.08 and above), do not drive under any circumstances. Driving while suspended in South Australia is a serious criminal offence that will dramatically worsen your situation.
4
Step 4 — Gather relevant information for your lawyer: Write down everything you remember about the breath test — the time, location, whether you had eaten or used mouthwash, any medical conditions, any unusual behaviour by police. This may be relevant to your defence or to mitigating your penalty.
5
Step 5 — Attend the Magistrates Court on your scheduled date: Your matter will be listed at the Magistrates Court of South Australia. Arrive early, dress appropriately, and if possible have legal representation. If you cannot afford a lawyer, contact Legal Aid SA before your court date or call Legal Hotline for guidance on what to expect.
Mistakes to Avoid
⚠️
Ignoring the charge or missing the court date: Some people in South Australia assume a drink driving charge will resolve itself or that a court summons is optional. It is not. Failing to appear at the Magistrates Court will result in a bench warrant for your arrest and may result in your matter being dealt with in your absence — almost always to your detriment.
⚠️
Pleading guilty at first mention without legal advice: South Australian courts list drink driving matters quickly. Many people plead guilty at their first appearance without understanding that mandatory minimum disqualification periods apply, that their plea may affect interlock eligibility, or that a procedural defence may have been available. Once you plead guilty, you cannot withdraw it without the court's leave.
⚠️
Assuming an expiation notice means no criminal record: For lower-range BAC readings, South Australian police may issue an expiation notice rather than a criminal charge. Many people pay this and believe the matter is closed. However, depending on your history and circumstances, electing to have the matter heard in court could sometimes produce a better outcome — or alternatively, paying the expiation without understanding its licence consequences can result in unexpected disqualification.
⚠️
Driving after an immediate licence suspension: When South Australian police suspend your licence on the spot following a high BAC reading, that suspension is immediate and real. Driving on a suspended licence is a criminal offence under the Road Traffic Act 1961 (SA), carries its own disqualification period, and will almost certainly result in a more serious outcome in court. Do not drive under any circumstances until you have confirmed your licence status with Service SA or a lawyer.
Likely Outcomes
The outcome of your South Australian drink driving matter depends heavily on your BAC reading, your licence history, the circumstances of the offence, and how well your case is presented.
For a first offence with a low-range BAC (0.05–0.079), you may receive an expiation notice with a fine and demerit points rather than a criminal charge. If it proceeds to the Magistrates Court, you may receive a fine and a minimum 3-month licence disqualification.
For a first offence mid-range reading (0.08–0.149), expect a criminal conviction, a fine ranging from several hundred to over a thousand dollars, and a mandatory minimum disqualification of at least 6 months. Community service or a good behaviour bond may also apply in some circumstances.
For a high-range reading (0.15 and above) or a second or subsequent offence, the Magistrates Court must impose a minimum 12-month disqualification, substantially higher fines, and in serious cases, a term of imprisonment — particularly for readings above 0.20 or where there was an accident or injury involved. Mandatory alcohol interlock conditions will apply before licence restoration for many offenders in this category.
A criminal conviction for drink driving in South Australia will appear on your criminal record and can affect employment, professional licences, and travel to certain countries. There are no guaranteed outcomes — call 1800 951 176 to discuss your specific situation.
First Offence, Low Range (0.05–0.079)
Possible expiation notice (fine + demerit points) or if in court: fine and minimum 3-month disqualification under Road Traffic Act 1961 (SA)
First Offence, Mid Range (0.08–0.149)
Criminal conviction in Magistrates Court SA, fine, mandatory minimum 6-month licence disqualification, possible interlock requirement
High Range (0.15+) or Repeat Offence
Criminal conviction, fine, mandatory minimum 12-month disqualification, mandatory interlock before reinstatement, possible imprisonment for serious cases
Licence Reinstatement (Interlock)
Many offenders must complete the SA Alcohol Interlock Program under Motor Vehicles Act 1959 (SA) before licence is restored — period varies by offence history and BAC level
Legal Aid in South Australia
Legal Aid SA is the primary provider of publicly funded legal assistance in South Australia. For drink driving matters, Legal Aid SA may be able to assist if you meet their means test and merit test — however, legal aid for summary traffic offences like drink driving is limited and is generally only available in more serious cases, such as those involving a risk of imprisonment or a particularly high BAC with serious consequences.
To apply for Legal Aid SA, you can contact them on 1300 366 424 or visit their offices at 82 Wakefield Street, Adelaide SA 5000. Regional offices are available in cities including Port Augusta, Port Pirie, and Mount Gambier. Their website at legalaidsa.gov.au also has an online application option.

Frequently Asked Questions — Drink Driving in South Australia
What are the BAC limits for drivers in South Australia?
In South Australia, the legal BAC limit for fully licensed drivers is 0.05 under the Road Traffic Act 1961 (SA). For learner drivers, P1 and P2 probationary licence holders, and certain professional drivers operating heavy vehicles or public passenger vehicles, the limit is 0.00 — meaning any detectable alcohol is an offence. Driving with a BAC between 0.05 and 0.079 is a low-range offence, 0.08 to 0.149 is mid-range, and 0.15 and above is high-range, with penalties escalating significantly at each level.
Will I automatically lose my licence after a drink driving charge in South Australia?
Yes, in most cases. South Australian law under the Road Traffic Act 1961 (SA) imposes mandatory minimum disqualification periods for drink driving offences. For a mid-range or high-range BAC, police will often suspend your licence at the roadside immediately. The Magistrates Court must then impose a disqualification period no less than the mandatory minimum upon a finding of guilt — the court has no discretion to go below that minimum. The length depends on your BAC category and whether you have prior offences. Call 1800 951 176 to understand the specific disqualification you face.
What is the alcohol interlock program in South Australia and will it apply to me?
The South Australian Alcohol Interlock Program is administered under the Motor Vehicles Act 1959 (SA). It requires eligible offenders to have an interlock device fitted to any vehicle they drive before their licence is reinstated after disqualification. The interlock prevents the vehicle from starting if the driver's breath registers alcohol. Interlock conditions apply to second or subsequent offenders and to many first-offence high-range (0.15+) offenders. The program lasts for a minimum period set by the court or the Department for Infrastructure and Transport. Breaching interlock conditions is a serious offence.
Can I contest a drink driving charge in South Australia?
Yes, you can contest a drink driving charge in the Magistrates Court of South Australia. Possible defences include procedural errors in how the breath test was conducted, issues with the calibration or operation of the Draeger Alcotest breath analysis instrument, or the 'two-hour rule' — if police did not administer the evidential breath test within two hours of you driving, there may be a defence. Successfully contesting a charge requires legal knowledge and preparation. Call Legal Hotline on 1800 951 176 to discuss whether the facts of your case may support a defence.
What happens if I miss my court date for a drink driving matter in South Australia?
If you fail to appear at the Magistrates Court of South Australia on your scheduled drink driving date, the magistrate will typically issue a bench warrant for your arrest. In some cases, the court may also deal with your matter in your absence and convict you without you being present, imposing penalties including disqualification. Missing a court date makes your situation significantly worse. If you have missed a date or are at risk of missing one, call Legal Hotline on 1800 951 176 immediately — there may be steps that can be taken to minimise the damage.
Will a drink driving conviction in South Australia give me a criminal record?
Yes. A drink driving conviction recorded in the Magistrates Court of South Australia is a criminal conviction and will appear on your criminal record. This can affect employment applications, professional licensing in fields such as healthcare, law, or childcare, and travel to some countries including the United States, which requires disclosure of criminal convictions on visa applications. For lower-range first offences dealt with by expiation notice, no conviction is recorded. Understanding the record consequences of your specific charge is critical — call 1800 951 176 to get clear advice.
Can I drive to work while my licence is disqualified in South Australia?
Generally, no. South Australia does not have a general 'work licence' equivalent to some other states. Once disqualified by the Magistrates Court under the Road Traffic Act 1961 (SA), you cannot drive regardless of employment necessity. There is no automatic hardship exemption. Driving while disqualified is a criminal offence that attracts its own penalties, including further disqualification and potential imprisonment. If maintaining employment is a critical concern, a lawyer may be able to argue this as a mitigating factor in sentencing. Call 1800 951 176 to understand your options before your court date.
What is an expiation notice for drink driving in South Australia and should I pay it?
An expiation notice is an on-the-spot penalty issued for some lower-range drink driving offences (BAC 0.05–0.079) in South Australia, similar to a traffic infringement. Paying the expiation means no criminal conviction is recorded, but demerit points and a licence suspension may still apply. Electing to have the matter heard in court instead is possible but carries risk — the court could impose a worse outcome. Before paying or electing court, get legal advice about the licence consequences specific to your history. Call Legal Hotline on 1800 951 176 to understand which option is better for you.
How long does a drink driving matter take to resolve in the South Australian Magistrates Court?
Most straightforward drink driving guilty pleas in the South Australian Magistrates Court resolve at first mention or within one to two court appearances — often within four to eight weeks of the charge. Contested matters that go to hearing take longer, potentially three to six months or more depending on court availability and complexity. During this time, any immediate licence suspension issued by police remains in effect. Your final disqualification period is set at sentencing. Delays can sometimes be managed strategically — a lawyer can advise on timing. Call 1800 951 176 for guidance on your specific timeline.
I was charged with drink driving in a regional area of South Australia — does it still go to the Magistrates Court?
Yes. The Magistrates Court of South Australia has registries throughout the state, including in Port Augusta, Port Pirie, Whyalla, Mount Gambier, Murray Bridge, and other regional centres. Your matter will be listed at the Magistrates Court closest to where the offence occurred or where you were charged. The same laws, mandatory penalties, and procedures apply statewide under the Road Traffic Act 1961 (SA) and Motor Vehicles Act 1959 (SA) regardless of location. Legal Hotline on 1800 951 176 can help you understand the process at your specific regional court and connect you with legal help in your area.
