You Were in a Crash and Taken to Hospital. How Does Drug Testing Work Now?

The Short Answer

If a vehicle is involved in an incident that injures someone, kills someone, or damages property, police can require a breath or saliva test from anyone they reasonably suspect was driving, attempting to drive, or in charge of it at the time.

If you're at hospital for treatment instead, police can require a sample there. Where the roadside request would have been for saliva, the hospital request can be for saliva for analysis or for blood. That request needs the approval of a doctor familiar with your injuries and your apparent state of health at the time, and it has to be made as soon as practicable and within three hours of the incident.

If you're unconscious or otherwise unable to communicate, nobody asks you. Police can require the doctor or nurse treating you to take blood, and it is lawful to take it without your consent.

This page is about that hospital pathway — not the roadside process, which we cover on our main page.

"Why Blood Instead of the Saliva Test?"

At hospital the request isn't limited to the sample type that would have been taken at the roadside. If the roadside request would have been saliva, police at hospital can require either saliva for analysis or blood for a laboratory test. If it would have been breath, they can require breath for analysis or blood.

There's a provision here that works in your favour. If you're asked for breath or saliva at hospital and you produce a doctor's certificate on the spot — one stating that a stated illness or disability makes you incapable of providing it, or that providing it could adversely affect your health — police must not require breath or saliva. They must require blood instead.

The three-hour rule matters. The hospital request must be made as soon as practicable and within three hours of the event that gave police the power to ask in the first place.

"What If I Was Unconscious?"

This is the part that surprises most people who've been through it. If you're a person police could have asked for a breath or saliva sample, and you appear to be unable to consent — because you're unconscious or otherwise unable to communicate — an officer can require the doctor or nurse treating you to take a blood sample for testing anyway.

The doctor or nurse taking that sample doesn't need your agreement. The law says plainly that it's lawful to take the sample even though you haven't consented to it. A qualified assistant — someone whose job includes taking blood — can take it if the doctor or nurse directs them to.

There's a limit on this. The doctor or nurse doesn't have to comply if they reasonably believe taking the sample would be prejudicial to your treatment, or they have some other reasonable excuse — the law's own example is a doctor who's in the middle of treating someone for a heart attack and can't stop to take the sample.

"Do I Get a Copy of the Sample?"

Where blood is taken under the no-consent hospital power, whoever takes it must take a second sample immediately afterwards and give it to you as soon as practicable. If you were unconscious, that second sample is often the first sign anyone gives you that a sample was taken at all.

Don't treat a missing second sample as an automatic win. Whether a result still gets into evidence when the procedure wasn't followed is a discretion the court exercises, and it has been exercised in the prosecution's favour before. It's worth raising; it isn't a guaranteed exclusion.

"Can I Refuse?"

You can physically refuse, and this is where people get the consequences badly wrong. Refusing a hospital request for breath, saliva or blood for analysis is not a small standalone fine. If you were driving, attempting to put the vehicle in motion, or in charge of it, the failure to provide is treated as an offence against the drink and drug driving provision itself — and you are liable to the same punishment in all respects, including disqualification from holding or obtaining a Queensland driver licence, as if you had actually committed that offence.

In practice that means refusing does not avoid the outcome. It substitutes a conviction and disqualification you can't argue down with a low reading, because there is no reading.

The flat 40 penalty unit / 6 months maximum that gets quoted for "failing to provide a specimen" applies to two different situations, neither of which is a driver refusing at hospital: refusing the initial roadside breath or saliva test, and a person who wasn't driving or in charge refusing a specimen for analysis. Check which one you've actually been charged with.

There is a defence, and the onus sits on you. You must satisfy the court that the request wasn't lawfully made, that you were incapable of providing the sample because of the events that occurred, or that there was some other reason of a substantial character for not providing it — other than a desire to avoid providing information that might be used in evidence.

None of this touches a blood sample taken while you were unconscious. That power doesn't ask for your agreement, so there's nothing to refuse.

"Does the Result Still Count as Evidence?"

Yes, and the timing matters. A laboratory finding that a relevant drug was present in your blood or saliva is conclusive evidence of that drug's presence at the time you gave the sample — and, if the sample was given not more than three hours after the material time, at that earlier time and all times in between. That's why the three-hour window isn't a technicality; it's tied directly to what the result is allowed to prove.

"Conclusive" has one opening. You can negative the result by proving the laboratory test result was not correct. That's a real burden, not a suggestion — it means evidence about the test itself, not doubt about it.

"What If No Doctor Is Available?"

If police believe a doctor isn't available at the hospital to take the sample — or a nurse isn't available either, for a blood sample — an officer can take you somewhere a doctor is known or reasonably believed to be available, whether or not you're under arrest. In practice, hospital drug testing after a crash can end up happening somewhere other than the hospital you were first taken to.

"I Was Hurt in the Crash — Does That Change Anything?"

Being injured doesn't stop the testing process, but it does interact with it in two ways. First, the doctor approving a blood sample request has to be familiar with your injuries and your apparent state of health at the time — the approval is specific to you, not a formality. Second, if you were unconscious or unable to communicate because of your injuries, that's exactly the situation the no-consent blood test power is written for, not an exception to it.

If you're facing other charges from the same crash — dangerous operation of a vehicle, for example — the sample matters there too. Evidence of a relevant drug's presence obtained under these provisions is admissible in a trial for offences connected with the driving of the vehicle, and it cannot be excluded only because it was compulsorily obtained. Get advice on all of it together, not the drug charge in isolation.

What To Do If This Has Happened To You

• Get a copy of the paperwork you were given — anything recording the time of the request, the time of the crash, and any certificate from a doctor.
• If you were unconscious, don't assume no sample was taken. Ask what was taken and when, once you're able to.
• Note the time of the crash as precisely as you can. The three-hour window is the first thing worth checking in any case like this.
• Get legal advice before you say anything to police about the circumstances of the crash itself, particularly if other charges might follow from it.
