How the 5-year conviction window works, how penalties escalate for second and third offences, when mandatory interlock applies, and the point at which imprisonment becomes unavoidable under Queensland law.
In Queensland, whether you are treated as a first, second, or subsequent offender for drink driving purposes depends on your conviction history within a rolling 5-year window. This window is set out in the Transport Operations (Road Use Management) Act 1995 (TORUM).
The critical date is the date of conviction — the date you were sentenced in court for the prior offence — not the date the prior offence actually occurred. If your prior conviction was finalised more than 5 years before the date the magistrate sentences you on the current matter, it falls outside the window and you are treated as a first offender.
Suppose you committed an offence in January 2020, but due to court delays you were not convicted until March 2021. The 5-year window runs from March 2021 (conviction), not January 2020 (offence). If you are sentenced on a new matter after March 2026, you fall outside the window and are treated as a first offender.
All drink and drug driving convictions count toward the 5-year repeat offence window, including:
The window is not limited to alcohol offences — a prior drug driving conviction can elevate the penalty category for a subsequent drink driving charge, and vice versa.
Queensland’s penalty structure escalates significantly with each repeat offence within the 5-year window. The three tiers below summarise the key changes by offence number.
| BAC Range | Offence # | Max Fine | Max Jail | Disqualification | Interlock |
|---|---|---|---|---|---|
| Low Range 0.050–0.099 | 1st | 14 PU (~$2,079) | 3 months | 1–9 months | Not mandatory |
| 2nd (5 yr) | 20 PU (~$2,970) | 6 months | 3–18 months | Mandatory | |
| 3rd+ (5 yr) | 28 PU (~$4,158) | 9 months | Extended | Mandatory | |
| Mid Range 0.100–0.149 | 1st | 20 PU (~$2,970) | 6 months | 3–12 months | Mandatory |
| 2nd (5 yr) | 20 PU (~$2,970) | 6 months | 3–18 months | Mandatory | |
| 3rd+ (5 yr) | 28 PU (~$4,158) | 9 months | 3–18 months+ | Mandatory | |
| High Range 0.150 and above | 1st | 28 PU (~$4,158) | 9 months | Min 6 months | Mandatory |
| 2nd (5 yr) | 60 PU (~$8,910) | 18 months | 1–3 years | Mandatory | |
| 3rd+ (5 yr) | Higher | Mandatory jail | Min 2 years | Mandatory |
PU = penalty unit. One penalty unit = $148.50 as at July 2025. Maximum penalties apply; actual penalties are at the magistrate’s discretion within the allowed range, except where mandatory minimums are specified.
For most repeat drink driving offences, imprisonment is available but not mandatory — the magistrate can still choose a non-custodial option. However, section 79(1C) of TORUM removes this discretion in one specific situation:
A third or subsequent high range drink driving conviction (BAC 0.150 or above) within a 5-year period triggers mandatory imprisonment under s.79(1C) TORUM. The magistrate cannot impose a community service order, a fine-only outcome, or a suspended sentence. A period of actual imprisonment is required by statute. This is the most serious automatic consequence in Queensland’s drink driving penalty framework.
Below this threshold, imprisonment remains at the court’s discretion. A second high range offence, or a third or subsequent mid or low range offence, does not automatically attract mandatory imprisonment — though the risk of a custodial sentence increases significantly with each escalation.
Even where s.79(1C) does not apply, a magistrate may impose imprisonment for repeat offences if there are aggravating circumstances, such as:
These circumstances do not trigger mandatory imprisonment by statute, but they substantially increase the likelihood that a magistrate will consider a custodial sentence appropriate even for a second offence.
A mandatory alcohol interlock condition applies to every repeat drink driving conviction — including a second low range conviction. This is a significant difference from first offences, where the interlock is only mandatory for mid and high range BAC readings.
The interlock period runs after the disqualification period ends. During the interlock period you may drive, but only in a vehicle fitted with an approved breath-test ignition device. The device must record a zero BAC before the vehicle will start. Breath tests may also be required at random intervals during the journey.
A common misconception is that the interlock is only for high BAC offences. For repeat offenders, it applies regardless of BAC range. If you have a prior drink driving conviction within 5 years and receive a second low range conviction, the interlock condition is mandatory.
A Work Licence under section 87 of TORUM is categorically unavailable to repeat offenders. One of the eligibility criteria is that the applicant must not have been convicted of a drink or drug driving offence within the preceding 5 years. A second or subsequent conviction within the window fails this test entirely.
There is no equivalent alternative restricted licence available in Queensland. Repeat offenders face the full disqualification period with no ability to drive for any purpose, work or otherwise, during that time.
Being a repeat offender does not mean the outcome is fixed. The mandatory minimums are fixed, but the final penalty the magistrate imposes — including the specific disqualification length, the fine amount, and whether a term of imprisonment is suspended or served — is still influenced by the quality of your plea in mitigation.
For repeat offenders, preparation is especially important because:
For a second high range conviction, the disqualification range is 1–3 years. The difference between 12 months and 36 months off the road is substantial. Preparation gives the magistrate a basis to impose a sentence toward the lower end of what the law permits.
The stakes are higher. The QLD Plea Program walks you through building the strongest possible plea — character references, a genuine written submission, and everything the magistrate needs to see to land toward the lower end of the permitted range.
The 5-year window is calculated from the date of your prior conviction (when you were sentenced), not the date of the prior offence. If your prior conviction was finalised more than 5 years before the current sentencing date, you are treated as a first offender. The window resets from conviction to conviction.
Mandatory imprisonment under section 79(1C) of TORUM applies to a third or subsequent high range drink driving offence (BAC 0.15 or above) within a 5-year period. The court cannot impose a non-custodial sentence in this situation. Below this threshold, imprisonment is possible but at the magistrate’s discretion.
Yes. A mandatory interlock condition applies to all repeat drink driving convictions, including a second low range offence. Unlike first offences (where interlock is only mandatory for mid and high range), the second conviction within 5 years triggers mandatory interlock regardless of BAC range.
No. The Work Licence eligibility criteria under section 87 of TORUM require that the applicant has not been convicted of a drink or drug driving offence within the preceding 5 years. Any repeat offender within the 5-year window is automatically ineligible, regardless of BAC or employment circumstances.
Second low range (within 5 yrs): up to 20 penalty units (~$2,970), up to 6 months jail, 3–18 months disqualification, mandatory interlock. Second mid range: same maximums. Second high range: up to 60 penalty units (~$8,910), up to 18 months jail, 1–3 year disqualification, mandatory interlock. Actual penalties are set by the magistrate within the statutory range.
Yes. Prior convictions for drug driving (both drug present and driving under the influence of a drug) count toward the 5-year repeat offence window. The window applies to all drink and drug driving offences, not alcohol-only matters.
Interstate drink or drug driving convictions are recognised in Queensland for the purposes of the repeat offence window. A prior conviction from another Australian state or territory can be counted as a prior conviction for penalty escalation purposes. Always disclose prior interstate matters when preparing your plea.
