Key points
- Three categories: category 1 (0.05 to under 0.08), category 2 (0.08 to under 0.15) and category 3 (0.15 or more).
- First category 1 offence: an expiation notice of $904 plus a $108 levy and 4 demerit points, and no disqualification if you pay it.
- First category 2: a fine of $900 to $1,300 and at least 6 months off the road. First category 3: $1,100 to $1,600 and at least 12 months.
- No jail for driving over the limit or refusing a test; only driving under the influence carries jail.
- The minimum disqualification is fixed, with no maximum. There is no work licence in South Australia.
- On-the-spot loss of licence for category 2 (6 months), category 3 and refusals (12 months). Interlock after category 3, a repeat category 2, a refusal or driving under the influence.

In South Australia, a first category 1 drink-driving offence (0.05 to under 0.08) is dealt with by a $904 expiation notice with no disqualification, while a first category 2 offence carries a fine of $900 to $1,300 and at least 6 months' disqualification, which the court cannot reduce unless the offence is trifling.
Checked on 22 October 2026 against the Road Traffic Act 1961 (version of 1 January 2026), the Motor Vehicles Act 1959 and its regulations, the expiation and sentencing laws, the South Australian Government's pages and the Legal Services Commission's Law Handbook. South Australia sets these fines in dollars. Where the Government's pages differ from the Act, this page follows the Act.
The limit and the three categories
| Category | Reading | Notes |
|---|---|---|
| Category 1 (often called low range) | 0.05 to under 0.08 | For unlicensed or disqualified drivers, and drivers of heavy vehicles (over 15 tonnes, or prime movers over 4 tonnes), buses, vehicles carrying passengers for hire and labelled dangerous-goods vehicles, any alcohol under 0.08 is a category 1 offence |
| Category 2 (mid range) | 0.08 to under 0.15 | Everyone |
| Category 3 (high range) | 0.15 or more | Everyone |
Learners, P1 and P2 drivers and probationary licence holders (which includes drivers on an interlock licence) must have no alcohol at all, as a condition of their licence. For a learner, P or probationary driver, a reading under 0.05 is a breach of that condition: a fine of up to $1,250 (or an expiation fee of $456, or $467 for a probationary licence) and a 6-month disqualification by the Registrar (longer for some repeat P drivers). At 0.05 or more it is also a drink-driving offence in the categories above.
Court penalties
| Offence | First offence | Second offence | Third offence | Later offences | Demerit points |
|---|---|---|---|---|---|
| Category 1: 0.05 to under 0.08 (in court) | Up to $1,100; at least 3 months off the road | Up to $1,100; at least 6 months | Up to $1,100; at least 9 months | Up to $1,100; at least 12 months | 4 |
| Category 2: 0.08 to under 0.15 | $900 to $1,300; at least 6 months | $1,100 to $1,600; at least 12 months | $1,500 to $2,200; at least 2 years | $1,500 to $2,200; at least 2 years | 5 |
| Category 3: 0.15 or more | $1,100 to $1,600; at least 12 months | $1,600 to $2,400; at least 3 years | $1,900 to $2,900; at least 3 years | $1,900 to $2,900; at least 3 years | 6 |
| Driving under the influence (section 47) | $1,100 to $1,600, or up to 3 months' jail; at least 12 months | Any later offence: $1,900 to $2,900, or up to 6 months' jail; at least 3 years | 6 | ||
| Refusing an alcotest or breath analysis, or a hospital blood test after a crash | $1,100 to $1,600; at least 12 months | Any later offence: $1,900 to $2,900; at least 3 years | 6 | ||
- No jail for driving over the limit or for refusing a test. Only driving under the influence carries jail: up to 3 months for a first offence, 6 months for a later one.
- The minimum disqualification cannot be reduced or replaced with another penalty, except for a first offence the court finds "trifling" on sworn evidence, and then not below one month. The Legal Services Commission says your need for a licence is irrelevant and trifling findings are extremely rare.
- There is no maximum disqualification: the court sets a period not less than the minimum. Disqualification cancels your licence.
- On top of the fine: a $287 victims of crime levy per offence (the Legal Services Commission also mentions a $150 prosecution fee), and for a first or second offence a compulsory lecture order unless there is proper cause not to make one, even if no conviction is recorded.
- A child under 16 in the vehicle (for a category 2 or 3 offence, driving under the influence or a refusal) means the same penalties, plus a compulsory alcohol dependency assessment before you can be relicensed.
- Failing to stop for a breath test carries up to $2,900.
Expiation notices (category 1 only)
- Only for category 1. A driver aged 16 or over with no other drink- or drug-driving offence in the look-back period cannot be prosecuted for a category 1 offence unless first given an expiation (on-the-spot) notice (Road Traffic Act 1961, section 47B(5)).
- The amount: a $904 fee plus a $108 victims of crime levy, and 4 demerit points. You have 28 days to pay.
- A first offence paid this way means no disqualification.
- If a second or later category 1 offence is dealt with by an expiation notice, the Registrar disqualifies you for 3, 6 or 12 months, depending on your earlier offences, and your licence is cancelled. The Government says there is no right of appeal against a drink-driving disqualification.
- Electing court: you can choose to go to court instead, by notice in the prescribed form. If convicted of a first category 1 offence, the fine is up to $1,100, the court must disqualify you for at least 3 months, and the $287 levy applies.
- Categories 2 and 3, driving under the influence and refusals have no expiation notice: they go to court.
Immediate loss of licence
- Police may give you an immediate loss of licence notice if they reasonably believe you committed a category 2 or 3 offence, or refused a breath test or a blood test after a crash. Not for category 1.
- How long: 6 months for category 2; 12 months for category 3 and for a refusal, under the Act (the Government's page says 6 months for a refusal). It ends earlier if your case is decided or withdrawn, or police confirm there will be no charge.
- When it starts: when it is given, or 48 hours later if the officer postpones it.
- Credit: the sentencing court must take the time you have served into account, and may backdate your disqualification.
- Challenging it: you can apply to the Magistrates Court. It may lift the notice on sworn evidence of a reasonable prospect of acquittal, or if no charge is laid within a reasonable time. It must cut it to 1 month for a first category 2 or 3 offence with a reasonable prospect of a "trifling" argument, or to 6 months where a category 3 charge may prove to be category 2.
The alcohol interlock
- Who: anyone relicensing after a court disqualification for a serious drink-driving offence: any category 3 offence, a second or later category 2 offence (with an earlier conviction other than category 1 within 5 years), driving under the influence of alcohol, and refusing a breath or blood test. Not category 1, and not a first category 2 offence.
- How long: the court's disqualification period (plus any immediate loss time, unless the disqualification was backdated), or 3 years, whichever is less. Time without the device fitted, or while suspended, does not count.
- Removal: after the minimum period, if no incidents were recorded in the previous 3 months.
- Exemption: only if a physical or medical condition prevents you from using an interlock and the device cannot reasonably be modified.
- Conditions: drive only your nominated vehicle with a working approved device, do not interfere with it, carry the provider's certificate and present the vehicle for checks; P plates, zero alcohol and the probationary conditions apply throughout. Breaching the conditions carries up to $2,500.
- Cost: the only government figure is the Registrar's fee of $20 for each month of the interlock period. You also pay the device provider; the Legal Services Commission says a concession scheme exists.
No work licence
South Australia has no work, restricted or hardship licence for a drink-driving disqualification. The Legal Services Commission says it is not possible to keep your licence even on a restricted basis, for example during working hours. The only hardship route in the law is for a P or probationary driver disqualified by the Registrar for breaking a licence condition, such as the zero-alcohol condition under 0.05: an eligible P driver may choose a Safer Driver Agreement instead, and where that is not available, a P or probationary driver may appeal on the ground of severe and unusual hardship (learners cannot appeal). It does not apply to a drink-driving disqualification by a court, or by the Registrar after a repeat expiation notice.
Refusing a test
- A breath test: refusing, failing to follow all reasonable directions, or refusing to blow is an offence. The defences are that the requirement was not lawfully made, that you were not given the chance to comply after the required advice, or "good cause"; for a medical condition you must ask for a blood sample instead. Not wanting to incriminate yourself, or having drunk after driving, is no excuse.
- A blood test after a crash: refusing a hospital sample without a genuine medical reason is an offence.
- The penalties are in the table above: higher than a first category 2 offence, the same as a first category 3.
How earlier offences are counted
- The look-back period is 3 years if the earlier offence was category 1, and 5 years otherwise, measured between the dates of the offences.
- In court, earlier convictions for drink- or drug-driving offences count, including driving under the influence and refusals.
- After an expiation notice, the Registrar counts offences that were either convicted or expiated.
No conviction recorded
The Sentencing Act 2017 lets a court, in some cases, impose a fine without recording a conviction (section 24) or dismiss a trifling charge (section 23). The Road Traffic Act's compulsory disqualifications apply when a court convicts. Whether an order without a conviction also avoids the compulsory disqualification depends on how the courts read those laws together, and the sources checked for this page do not settle it, so get advice before you rely on it.
Getting your licence back, and driving while disqualified
When the disqualification ends, you must reapply. A former full licence holder gets a probationary licence, generally for 12 months, with conditions: zero alcohol, carry your licence at all times, and stay below 2 demerit points. Repeat offending within 5 years can mean an alcohol dependency assessment first. Driving while disqualified carries up to 12 months' jail, or 3 years for a later offence; driving after a serious drink-driving disqualification without being relicensed carries up to $5,000 or 1 year. An appeal against a court's sentence goes to a single judge of the Supreme Court; the Legal Services Commission says within 21 days.
