Dangerous Operation of a Motor Vehicle Causing Death or Grievous Bodily Harm in Queensland
In Queensland, dangerous driving causing death or grievous bodily harm (GBH) is charged as dangerous operation of a motor vehicle under section 328A of the Criminal Code. It carries a maximum of 14 years imprisonment, or 20 years where a circumstance of aggravation applies. The prosecution must prove both that the vehicle was operated dangerously and that the dangerous operation caused the death or injury.
A charge arising from a fatal or very serious road accident is different from an ordinary traffic matter. There has been a death or significant injury, often in circumstances that affect the driver, the injured person and their families well beyond the criminal proceedings.
In Queensland, what people commonly call dangerous driving causing death, dangerous driving occasioning death or dangerous driving causing grievous bodily harm is dealt with under section 328A of the Criminal Code 1899. The Queensland offence is dangerous operation of a vehicle causing death or grievous bodily harm.
The seriousness of the result does not, by itself, establish the offence. The prosecution must still prove that the vehicle was operated dangerously and that the dangerous operation caused the death or grievous bodily harm.
This article explains the current Queensland law, the circumstances of aggravation, the penalties that can apply, the distinction between dangerous and careless driving, and what generally happens after a person is charged.
What is dangerous operation of a motor vehicle?
Section 328A makes it an offence to operate, or interfere with the operation of, a vehicle dangerously in any place.
For the more serious offence involving death or grievous bodily harm, the prosecution must establish that:
- the accused operated a vehicle, or interfered with its operation;
- this occurred in a place to which the section applies;
- the operation or interference was dangerous; and
- the dangerous operation caused another person's death or grievous bodily harm.
If a circumstance of aggravation is alleged, the prosecution must also prove that circumstance.
The Queensland Supreme and District Courts Benchbook confirms that the dangerous operation does not have to be the sole cause of the death or injury. It is enough if the dangerous driving was a substantial or significant cause of the result.
What does "dangerous" mean?
The legal question is not simply whether the driver made a mistake.
Section 328A defines dangerous operation by reference to operating a vehicle at a speed or in a way that is dangerous to the public, having regard to all the circumstances. Those circumstances include the nature and use of the place, the condition of the vehicle, the number of people or vehicles present or reasonably expected to be present, the concentration of alcohol in the driver's blood or breath, and the presence of other substances in the driver's body.
Dangerousness is assessed objectively. A driver does not have to intend to drive dangerously or intend to hurt anyone before the offence can be committed.
At the same time, careless driving and dangerous operation are not the same thing. The fact that a driver was at fault, or even that the consequences were catastrophic, does not automatically establish dangerous operation.
That distinction can be one of the most important issues in a case.
Does a fatal accident automatically mean dangerous driving?
No.
A person may cause a collision through a failure to take proper care without their driving necessarily reaching the criminal threshold for dangerous operation.
Conversely, dangerous operation does not require prolonged reckless behaviour. Depending on the circumstances, a comparatively short period of driving can still be dangerous. The court considers what actually happened, the risk created by the driving and the surrounding circumstances rather than applying a rule based only on the length of time involved.
This is particularly important in cases involving allegations such as failing to see another road user, crossing into another lane, fatigue, distraction, an unsafe overtaking manoeuvre or losing control of a vehicle.
The outcome of the collision is plainly relevant, but it does not replace the need to prove the underlying dangerous driving.
Dangerous driving causing death in Queensland
Where dangerous operation causes another person's death, section 328A(4) applies.
People searching online commonly use expressions such as dangerous driving causing death, dangerous driving occasioning death, causing death by dangerous driving and death by dangerous driving. In Queensland, these expressions will usually be referring to the offence of dangerous operation of a vehicle causing death.
For the prosecution to succeed, it must prove both the dangerous operation and the required causal connection between that driving and the death. It is not necessary for the person to die at the scene of the collision. The issue is whether the dangerous operation legally caused the death.
There can also be more than one cause of a fatal collision. The involvement or error of another road user does not necessarily prevent a prosecution, but it may be highly relevant to reconstructing what happened and deciding whether the accused driver's conduct was dangerous and whether it caused the death.
Sentence for dangerous driving causing death in Queensland
There is no single sentence for dangerous driving causing death.
Under the current law, dangerous operation causing death carries a maximum penalty of 14 years imprisonment if none of the specified circumstances of aggravation applies. If one of the relevant statutory circumstances of aggravation does apply, the maximum is 20 years imprisonment.
Those are maximum penalties. They should not be read as a prediction of what sentence will be imposed in an individual case.
Sentencing requires the judge to consider the whole circumstances of the offending and the offender. In a dangerous-operation case, matters such as the degree and duration of the dangerous driving, speed, alcohol or drug involvement, the nature of the collision, previous traffic or criminal history, an early plea of guilty, remorse, cooperation, rehabilitation and personal circumstances can all become relevant.
The distinction between a relatively brief error of judgment and deliberate or sustained high-risk driving can be important. So too can the distinction between a driver with no relevant history and someone with previous serious driving offending.
A death necessarily makes the offence extremely serious, and imprisonment is a real possibility even for a person who has never previously been before a criminal court. It is nevertheless wrong to assume that every case produces the same sentence.
Dangerous driving causing grievous bodily harm in Queensland
Section 328A(4) also applies where dangerous operation causes grievous bodily harm, usually referred to as GBH.
This is the offence people may find when searching for dangerous driving causing grievous bodily harm, dangerous driving causing serious injury or dangerous driving causing bodily harm.
Not every significant injury is legally grievous bodily harm.
Under the Criminal Code, GBH includes the loss of a distinct part or organ of the body, serious disfigurement, or an injury which, if left untreated, would endanger or be likely to endanger life or cause or be likely to cause permanent injury to health. The fact that treatment was available does not prevent an injury satisfying the definition.
That means the medical evidence can be important. An injury may plainly be serious without necessarily satisfying the statutory definition of GBH, while some injuries that respond well to medical treatment can still legally amount to GBH because of what would have happened if they were left untreated.
Penalty for dangerous driving causing grievous bodily harm
The statutory maximum penalties are the same as those applying where dangerous operation causes death: 14 years imprisonment ordinarily, or 20 years where a relevant circumstance of aggravation applies.
That does not mean a death case and a GBH case are sentenced in the same way.
The actual injury remains highly relevant. A judge will consider matters such as the seriousness and permanence of the injury, its effect upon the injured person, the level of danger created by the driving and the offender's personal circumstances.
Circumstances of aggravation in dangerous driving causing death or GBH
A person searching for aggravated dangerous driving occasioning death may find material from other Australian jurisdictions. Queensland uses a different statutory structure.
Under the current Queensland law, section 328A(4) identifies particular circumstances of aggravation. If one of them applies to dangerous operation causing death or GBH, the maximum penalty increases from 14 years to 20 years imprisonment.
Alcohol or drugs
The higher maximum applies where the driver was adversely affected by an intoxicating substance at the time of the offence.
That wording matters. The current aggravating circumstance is not simply that alcohol or a drug was detected. The prosecution must establish the statutory circumstance alleged.
Alcohol and drugs can also be relevant to the underlying question of whether the operation of the vehicle was dangerous, because section 328A expressly requires the court to have regard to alcohol concentration and the presence of other substances when considering dangerousness.
Excessive speeding
A circumstance of aggravation also applies where the offender was excessively speeding.
For section 328A, that term has a specific meaning: driving or operating the vehicle more than 40 km/h above the speed limit applying to the driver.
Speed below that threshold can still be important to deciding whether driving was dangerous. The 40 km/h threshold relates to this particular statutory circumstance of aggravation.
Unlawful racing or speed trials
The 20-year maximum can also apply where the driver was taking part in an unlawful race or unlawful speed trial when committing the offence.
Again, the prosecution must prove the aggravating circumstance as part of the case if it relies upon it.
Leaving the scene after someone is killed or injured
Section 328A contains a specific circumstance of aggravation dealing with leaving the scene.
It applies where the driver knew, or ought reasonably to have known, that another person had been killed or injured and left the scene before a police officer arrived. There is an exception where the driver leaves to obtain medical or other help for the other person.
This provision is therefore more specific than simply asking whether somebody physically left the location after an accident. The driver's knowledge, the reason for leaving and the timing can all matter.
Evading police
The higher maximum can also apply if, before or while committing the dangerous-operation offence, the offender commits the evade-police offence under section 754(2) of the Police Powers and Responsibilities Act 2000.
Queensland's dangerous driving law may change in 2027
There is a significant proposed change to this area of law.
As at September 2026, the Criminal Code (Dangerous Driving) and Other Legislation Amendment Bill 2026 remains before the Queensland Parliament. It was introduced on 26 June 2026 and the parliamentary committee reported on it on 14 August 2026. It has not yet become law, so the present section 328A provisions explained above continue to apply.
If the Bill passes in its present form, the current section 328A framework for driving a motor vehicle would be replaced by new provisions including proposed section 334I. Under that proposed section, dangerous driving causing death or grievous bodily harm would carry an ordinary maximum of 16 years imprisonment.
Where one of the proposed circumstances of aggravation applies, the maximum for causing death or GBH would increase to 25 years imprisonment. The proposed aggravating circumstances are broader than those in the present law and include additional matters concerning alcohol or drugs, disqualified or suspended driving and certain previous driving convictions.
The Bill is presently drafted to commence on 1 March 2027. Because it is still before Parliament, its final wording and commencement position can change before it becomes law.
If the legislation changes, the date of the alleged driving will be important in identifying which law applies. This page should therefore be reviewed again when the Bill is finally dealt with by Parliament.
Dangerous driving causing death or GBH compared with careless driving
This distinction is often more important than the labels suggest.
Careless driving involves driving without due care and attention or without reasonable consideration for other road users. Dangerous operation requires the higher threshold of driving that is dangerous to the public in the circumstances.
A death or very serious injury does not automatically turn careless driving into dangerous operation.
For example, there can be cases where nobody disputes that the driver made an error and that the error caused the collision, but there remains a genuine legal issue about whether the error was sufficiently serious to constitute dangerous operation rather than careless driving.
That issue cannot usually be resolved from the short police summary of the accident alone. The actual evidence needs to be considered.
Can dangerous driving causing death be reduced to careless driving?
In an appropriate case, yes.
If the prosecution evidence supports a failure to take due care but does not establish dangerous operation beyond reasonable doubt, representations can be made seeking withdrawal of the dangerous-operation charge and substitution of an appropriate lesser charge.
At Clarity Law this type of process is generally referred to as case conferencing or negotiations with the prosecution.
A charge is not reduced simply because the driver has a good history, did not intend the collision or has suffered greatly as a result of what occurred. The important question is whether the available evidence supports the legal elements of the charge that has actually been brought.

What evidence is important in a dangerous operation case?
Cases involving a death or GBH often involve considerably more evidence than an ordinary traffic prosecution.
Police may obtain crash-scene photographs and measurements, witness statements, CCTV or dashcam footage, vehicle data, telephone evidence, blood or breath results, toxicology evidence, medical records and mechanical inspection material. In a serious collision, specialist crash investigators may also reconstruct the accident and provide opinions about matters such as speed, braking, visibility and the movement of the vehicles.
That evidence needs to be considered against the prosecution's precise allegation about what made the driving dangerous.
If the allegation is excessive speed, the evidence may centre on speed calculations and vehicle data. If the allegation concerns fatigue or distraction, the relevant evidence may be quite different. If another road user contributed to the collision, their movements and the opportunity available to the accused driver to react can become particularly important.
For that reason, the police description of the incident is only the starting point.
What legal issues or defences can arise?
The issues depend on the individual case.
A person may dispute that they were the driver, that the driving was dangerous, or that their driving caused the death or GBH. Other cases can involve an unexpected mechanical failure, a sudden medical event, an extraordinary emergency or a factual dispute about how the collision occurred.
One point that sometimes causes confusion is intention. A person can be convicted of dangerous operation even though they never intended to hurt anyone and believed at the time that they were driving safely. The focus is principally on the objective danger created by the driving.
There can also be cases where a person accepts that they caused the accident and accepts significant personal responsibility for what happened, but disputes that their driving satisfies the legal test for dangerous operation. Those positions are not necessarily inconsistent.

What court deals with dangerous driving causing death or GBH?
A charge will ordinarily start in the Magistrates Court.
Dangerous operation causing death or grievous bodily harm under section 328A(4) is a crime dealt with on indictment. For an adult, the matter will ordinarily progress from the Magistrates Court through the committal process and ultimately be dealt with in the District Court.
If the accused ultimately pleads guilty, the sentence will take place in the higher court. If the charge is defended, it can proceed to a trial before a judge and jury.
The early Magistrates Court appearances do not usually determine guilt or sentence. They allow time for the prosecution evidence to be obtained, considered and the future course of the case determined.
Police are responsible for investigating the collision. Once the indictable proceedings move into the higher court, the prosecution is ordinarily conducted by the Queensland Office of the Director of Public Prosecutions.
We appear in Magistrates and District Courts across Queensland, including Brisbane, Southport, Ipswich, Beenleigh, Maroochydore, Toowoomba and Cairns.
How long will the case take?
There is no reliable single timeframe for a dangerous operation causing death or GBH matter.
Serious collision investigations can take time, particularly where accident reconstruction, medical evidence, toxicology, electronic data or expert reports are required. Once the prosecution brief is available, there may then be further investigation, negotiations or expert evidence before the case is ready to be committed to the District Court.
A guilty plea will generally resolve sooner than a defended trial, but even a matter in which a person intends to plead guilty should not be finalised until the charge and prosecution facts have been properly considered.
For this reason, broad internet estimates about how many months a dangerous driving case will take are often of limited value.
Licence disqualification for dangerous operation causing death or GBH
A conviction on indictment under section 328A(4) carries an automatic Queensland driver licence disqualification.
Under the current section 86 of the Transport Operations (Road Use Management) Act 1995, the statutory period for a section 328A(4) conviction is one year, subject to provisions that can produce longer periods because of relevant previous convictions. The sentencing judge also has power to order a longer period of disqualification.
The one-year period is therefore a statutory starting point, not a prediction that every person convicted of causing death or GBH will lose their licence for exactly one year.
A work licence does not provide a way around a disqualification for dangerous operation causing death or GBH.
Speaking to police after a fatal or serious traffic accident
A driver may be asked to provide an account of the accident while police are still investigating whether criminal charges should be brought.
There can be legal obligations to provide particular information or comply with specific statutory requirements. That is different from voluntarily participating in a detailed police interview about how and why the accident occurred.
A person suspected of a criminal offence generally has a right to silence, subject to those specific legal obligations. Before participating in a formal interview or supplying a detailed statement about the collision, it is sensible to obtain legal advice about the particular circumstances.
This is especially important in serious traffic cases because statements made during the investigation may later form part of the prosecution evidence.
Frequently asked questions
Is dangerous driving causing death the same as dangerous operation causing death?
In ordinary conversation, usually yes. Dangerous driving causing death is the phrase many people use, while the current Queensland offence is contained in section 328A under the heading dangerous operation of a vehicle.
For a motor-vehicle case, the expression dangerous operation of a motor vehicle causing death accurately describes the type of charge being dealt with.
What does dangerous driving occasioning death mean in Queensland?
People commonly search for dangerous driving occasioning death, but "occasioning death" is not the wording used in current Queensland section 328A.
The Queensland provision refers to dangerous operation which causes the death of another person.
What is aggravated dangerous driving occasioning death?
Queensland does not presently use aggravated dangerous driving occasioning death as the formal name of an offence.
Instead, section 328A(4) provides specific circumstances that increase the maximum penalty from 14 years to 20 years. They include being adversely affected by an intoxicating substance, excessive speeding, unlawful racing or speed trials, specified leaving-the-scene conduct and evading police.
Is reckless driving causing bodily harm a Queensland offence?
"Reckless driving causing bodily harm" is not the usual name of the Queensland offence dealt with on this page.
Depending on what occurred and the seriousness of the injury, the relevant Queensland offence may be careless driving, dangerous operation, or dangerous operation causing grievous bodily harm.
Is dangerous driving causing serious injury the same as causing GBH?
Not necessarily.
"Serious injury" is an ordinary-language expression. Grievous bodily harm has a specific definition under the Queensland Criminal Code. Medical evidence may therefore be required before it can be determined whether a particular serious injury legally amounts to GBH.
Does someone have to die immediately for the charge to apply?
No.
A person can die later from injuries sustained in the collision. The legal issue is whether the dangerous operation was a substantial or significant cause of the death.
What if the other driver was also at fault?
That does not automatically prevent a dangerous-operation charge.
There can be more than one contributing cause of an accident. The conduct of another road user can nevertheless be important when deciding exactly what happened, whether the accused person's driving was dangerous and whether it made the required contribution to the death or injury.
Can someone be convicted even though they never intended to hurt anybody?
Yes.
Dangerous operation does not generally require an intention to cause injury or death. Many prosecutions arise from driving where there was no suggestion that the driver wanted anybody to be harmed.
Is imprisonment automatic?
No. Section 328A(4) does not impose the same sentence on every offender.
The offence is, however, very serious and imprisonment is a realistic outcome, particularly where a person has died. The appropriate sentence depends upon the circumstances of the driving, the consequences and the offender.
Can the charge be defended even though an accident obviously occurred?
Yes.
The existence of the accident is not the legal test. Depending upon the case, the dispute may concern who was driving, whether the driving was dangerous, whether it caused the death or GBH, whether a circumstance of aggravation is proved, or whether the evidence instead supports a lesser driving offence.
What we look at in a dangerous operation causing death or GBH case
The first question is usually not simply, "Was there a terrible accident?" That fact may already be beyond dispute.
The more useful questions are what the prosecution says the driver did, what evidence supports that allegation, whether the conduct was legally dangerous, whether it caused the death or GBH, and whether any alleged circumstance of aggravation can actually be proved.
Where the charge is supported by the evidence, the focus moves to the correct prosecution facts, preparation for sentence and the material that will assist the judge to understand both the offending and the person being sentenced.
Where the evidence does not establish dangerous operation, it may instead be necessary to challenge the charge or make representations about whether a lesser offence more accurately reflects what occurred.
