Queensland strictly enforces zero-tolerance drug driving laws, meaning a positive roadside saliva test results in charges regardless of driving impairment – even for medicinal cannabis users. Offences fall into two categories: standard Driving With a Relevant Drug Present (which relies solely on drug detection and offers work licence eligibility for open licence holders) and the more severe Driving Under the Influence (DUI) of a Drug (which requires proof of impairment, carries harsher penalties, and bars work licence applications). Licences face immediate suspension upon charge, but defence options (including challenging testing procedures, chain-of-custody or necessity) remain available through legal representation.
Queensland has a zero-tolerance policy for drug driving. Under the Transport Operations (Road Use Management) Act 1995, a positive roadside saliva test for a relevant drug results in a charge regardless of whether your driving was affected at all.
Unlike drink driving, where a reading below a certain threshold determines the severity of the charge, drug driving in Queensland requires no proof of impairment.
If you have been charged with a drug-driving offence, the drug possession lawyers at Hounsell Cunningham can help you understand where you stand. This article covers the two categories of drug driving offences under Queensland law, the penalties attached to each, what happens to your licence immediately after a charge, and what defence and work licence options may be available to you.
The Two Drug Driving Offences in Queensland
Driving With a Relevant Drug Present (The Less Serious Charge)
Under section 79(2AA), this charge applies where a roadside saliva test returns a positive result for a relevant drug, like cannabis (THC), methylamphetamine (ice), cocaine or MDMA (ecstasy), regardless of whether your driving was impaired. Proof of impairment is not required, which means a positive test result is sufficient.
The penalties that apply depend on your offence history:
- First offence: Maximum fine of 14 penalty units, up to three months imprisonment, and minimum licence disqualification of one month.
- Second offence within five years: Maximum fine of 20 penalty units, up to six months imprisonment, and minimum disqualification of three months.
- Third and subsequent offences within five years: Maximum fine of 28 penalty units, up to nine months imprisonment, and minimum disqualification of six months.
Driving Under the Influence of a Drug (The More Serious Charge)
Under section 79 of the Act, a DUI applies where police form the view that your driving was visibly impaired by a drug or where a blood test shows a significant level of drug presence. Proof of impairment is required, but the drug does not need to be one of the four substances tested by roadside saliva screening. Any drug can form the basis of a DUI charge.
The penalties that apply depend on your offence history:
- First offence: Maximum fine of 28 penalty units, up to nine months imprisonment, and minimum licence disqualification of six months.
- Second offence within five years: Up to 18 months imprisonment and minimum disqualification of 12 months.
- Third and subsequent offences within five years: Mandatory imprisonment requirements apply.
As of December 2026, Queensland will double penalties for drug driving offences as part of broader road safety reforms. Importantly, the Queensland government has confirmed it will take a zero-tolerance approach to drug driving, including for those with medicinal cannabis prescriptions.
What Happens to Your Licence Immediately After a Charge
Upon being charged with a drug driving offence in Queensland, your licence is suspended immediately for 24 hours. If you are charged with a more serious offence, that suspension continues until the matter is finalised in court. You do not need to be convicted for your licence to be affected. The suspension begins at the point of charge.
Work Licence Applications After a Drug Driving Charge
If you are charged with driving with a relevant drug present (not DUI) and you hold an open Queensland licence, you may be eligible to apply for a work licence. A work licence allows you to continue driving for employment purposes during the period of disqualification.
To be eligible, you must:
- Hold a current open Queensland licence
- Have no disqualifications or suspensions in the past five years
- Demonstrate that losing your licence would cause extreme financial hardship
If you are charged with driving under the influence of a drug, it is not possible to apply for a work licence or any type of hardship licence.
Drug Driving Defence Options in Queensland
A drug driving charge in Queensland is not automatically a conviction. Several defence avenues may be available depending on the circumstances of your matter:
- Testing procedure challenges: Whether the roadside saliva test and subsequent laboratory analysis were conducted in accordance with prescribed protocols.
- Chain of custody issues: Whether the sample was correctly handled, stored and identified from collection through to laboratory analysis.
- Honest and reasonable mistake of fact: In limited circumstances, where a person was genuinely unaware that a drug was present in their system.
- Necessity: Where driving was the only reasonable response to an emergency situation.
The strength of any defence depends on the specific facts of your case. Drug driving laws in Queensland are technical, and the procedural requirements around testing are detailed. An error in the testing or handling process can have significant consequences for the admissibility of evidence.

Frequently Asked Questions About Drug Driving Laws in Queensland
What drugs are tested for in a Queensland roadside drug test?
Queensland roadside saliva tests screen for four drugs: THC (cannabis), methylamphetamine (ice), cocaine and MDMA (ecstasy). A positive result for any of these substances will result in a drug driving charge regardless of whether your driving was impaired.
What is the difference between drug driving and DUI of a drug in Queensland?
Driving with a relevant drug present requires only a positive saliva test result; no proof of impairment is needed. Driving under the influence of a drug (DUI) requires evidence that the driver was visibly impaired. As you can see, DUI carries significantly higher penalties and more limited licence options.
Can I get a work licence after a drug driving charge in Queensland?
A work licence may be available if you are charged with driving with a relevant drug present, hold an open Queensland licence, have no disqualifications in the past five years, and can demonstrate extreme financial hardship. Work licence applications cannot be made if you are charged with DUI of a drug. Contact Hounsell Cunningham to discuss your work licence eligibility.
