Tested Positive at a Roadside Drug Test in Queensland? What Happens Next
Last verified:
First: breathe. Here's the Queensland sequence.
Queensland remains one of the strict states: a prescription is no defence to driving with detectable THC, and reform is at the "under consideration" stage — not law. Knowing the process helps you make fewer mistakes this week.
1. The roadside process. A positive saliva screen leads to a second test; a confirmed positive means you cannot drive for a period. Arrange transport.
2. Laboratory confirmation. The sample goes to a lab; roadside results are indicative only. Charges typically follow confirmation.
3. Which offence — this matters enormously. Queensland runs two separate offences under section 79 of the Transport Operations (Road Use Management) Act 1995: driving with a relevant drug present (the presence offence — no impairment needed), and the far more serious driving under the influence, charged where a driver appears adversely affected. Same stop, very different consequences. If anything in your paperwork says "under the influence," treat getting a lawyer as urgent, not optional.
4. Court. Presence-offence convictions mean court-ordered disqualification (minimum one month for a first offence), a fine and a traffic record. Whether a work licence is available for drug-driving in Queensland is contested — legal sources conflict — and eligibility rules are strict and time-sensitive either way, which is another reason early advice pays.
What to do this week
- Write down everything now: stop time, what was said, last dose and product. Detail fades fast.
- Gather documents: prescription, dispensing records, prescriber guidance.
- Check your paperwork for which offence is alleged — presence or under the influence — and tell your lawyer immediately.
- Ask a lawyer about work-licence options before your court date, not after. Some options close permanently once a matter is finalised.
- Tell your prescriber what happened.
What NOT to do
- Don't rely on the reform review. The government confirmed in June 2026 it is "carefully considering recommendations" — that helps nobody currently charged.
- Don't assume "I wasn't high" helps with a presence charge. Presence is the offence.
- Don't miss a court date — it converts a bad week into a worse year.
- Don't post details publicly while the matter is live.
The reform picture
A TMR review of drug-driving law and medicinal cannabis has been handed to government, a proposed amendment (inserting a s79(2AB) defence for lawful, unimpaired use) has been floated in Parliament, and an e-petition remains active. Until something passes and commences, the current law applies in full. Follow every move on our Reform Tracker.
