Dangerous driving occasioning grievous bodily harm in NSW.

What is dangerous driving occasioning grievous bodily harm?

The offence sits in section 52A(3) of the Crimes Act 1900 (NSW). A person is guilty if the vehicle they were driving is involved in an impact occasioning grievous bodily harm to another person, and at the time of the impact the driver was driving in one of three ways set out below. It is the serious-injury counterpart of dangerous driving occasioning death, which sits in section 52A(1).

This is a serious indictable offence. It is dealt with in the District Court after a committal in the Local Court. A conviction means a criminal record, a period of licence disqualification, and a real risk of a term of imprisonment. It is not a traffic infringement, and it is not an offence that can be dealt with by a fine alone in the ordinary case.

What does the prosecution have to prove?

The Crown must prove three things beyond reasonable doubt. First, that the accused was driving a vehicle. Second, that the vehicle was involved in an impact occasioning grievous bodily harm to another person. Third, that at the time of the impact the accused was driving in one of these ways: under the influence of intoxicating liquor or of a drug; or at a speed dangerous to another person or persons; or in a manner dangerous to another person or persons.

The words "involved in an impact" do a lot of work. The Crown does not have to prove that the accused caused the impact in the ordinary sense, and the test for dangerous speed or dangerous manner is objective. The question is whether the speed or manner of driving was dangerous to the public, judged against the standard of a reasonable driver, not whether this driver was careless or meant any harm. A driver can be guilty without intending to hurt anyone and without being reckless.

What counts as grievous bodily harm?

Grievous bodily harm means really serious harm. Section 4 of the Crimes Act says it includes any permanent or serious disfiguring of the person, the destruction of a foetus other than in a medical procedure, and any grievous bodily disease. Broken bones, internal injuries, brain injury and lasting disfigurement are the kinds of injury that meet the test. The same standard applies in the assault offences of reckless grievous bodily harm and grievous bodily harm with intent.

Where the injuries are real but fall short of grievous bodily harm, section 52A does not apply. The matter may then proceed as negligent driving, which has its own tiers for death, for grievous bodily harm, and for lesser injury. The level of injury can decide which charge a driver faces, so the medical evidence matters from the start.

What makes the offence aggravated?

Section 52A(4) creates an aggravated form of the offence. The circumstances of aggravation are set out in section 52A(7). The offence is aggravated if, at the time, the driver had a prescribed concentration of alcohol of 0.15 or more present in their blood or breath; or was driving more than 45 km/h over the speed limit; or was driving to escape pursuit by police; or was very substantially impaired by alcohol, a drug, or a combination of the two.

Any one of those is enough. The presence of a single circumstance of aggravation lifts the maximum penalty and changes the way the offence is viewed on sentence. High-range alcohol readings and excessive speed are the two that come up most often, and they frequently appear together with the evidence from a breath or blood analysis.

What is the maximum penalty?

For dangerous driving occasioning grievous bodily harm under section 52A(3), the maximum is 7 years imprisonment. For the aggravated offence under section 52A(4), the maximum is 11 years. The death offences carry higher maximums again: 10 years under section 52A(1), and 14 years for the aggravated offence under section 52A(2).

These are maximum penalties, set for the worst category of case. The sentence in any given matter depends on the objective seriousness of the driving and on the offender's circumstances. A conviction also carries a period of licence disqualification, which sits on top of any sentence of imprisonment.

Will a court send you to gaol?

For an offence of this seriousness, a full-time custodial sentence is the usual result. The Court of Criminal Appeal has issued a guideline judgment for section 52A offences, which the sentencing court works through alongside the general law of sentencing. The guideline was most recently restated in Cripps v R [2026] NSWCCA 144, a five-judge decision that revoked the earlier guideline in R v Whyte and stated the guideline afresh.

The thrust of the guideline is that a sentence other than full-time imprisonment is reserved for exceptional cases. The objective seriousness of the driving is central. A court will look at the degree of speed, the degree of intoxication, the length and nature of the dangerous driving, the number of people put at risk, and whether the driving was a momentary lapse or a sustained course of conduct. The offender's good character, a plea of guilty, remorse, and prospects of rehabilitation all count, but they are weighed against a starting point that assumes custody. The same guideline governs the death offences.

Dangerous driving or negligent driving: what is the difference?

The two offences sit at different levels. Dangerous driving under section 52A requires driving that is objectively dangerous, or driving under the influence, and it is a serious indictable offence with the maximums set out above. Negligent driving occasioning grievous bodily harm under section 117 of the Road Transport Act 2013 (NSW) has a lower threshold, being a departure from the standard of care of a reasonable driver. It is dealt with summarily in the Local Court. The maximum is 9 months imprisonment or 20 penalty units for a first offence, and 12 months or 30 penalty units for a second or later offence.

The gap between the two is wide, and the line between them is often where a serious driving matter is won or lost. The Crown sometimes lays both, in the alternative. Where the evidence of dangerous driving is thin, a negotiated plea to negligent driving can move the matter from the District Court to the Local Court and change the sentencing range entirely.

What are the defences?

Section 52A(8) sets out a statutory defence. It is a defence if the accused proves that the grievous bodily harm was not in any way attributable to the fact that the accused was under the influence, or to the speed at which the vehicle was driven, or to the manner in which it was driven, as the case may be. The onus is on the accused, on the balance of probabilities. That is a reverse onus, and it is one reason the expert and medical evidence on causation has to be examined closely.

Beyond the statutory defence, a charge may be contested on identity, on whether the speed or manner of driving met the objective standard of dangerousness, and on whether the injuries amount to grievous bodily harm. There is also the question of whether the driving was voluntary. A driver who loses control through a sudden medical event may be able to raise automatism, the issue examined by the Court of Criminal Appeal in El Seidi v R [2026] NSWCCA 143. Each of these turns on the detail of the brief.

What we do for clients charged with a serious driving offence.

The work starts with the brief. We read the police facts against the physical evidence, the collision reconstruction, any certificate of analysis for alcohol or drugs, and the medical reports that establish the level of injury. We test whether the driving met the objective standard, whether the injuries reach grievous bodily harm, and whether the section 52A(8) defence is open on causation. Where the case for dangerous driving is weak, we look to negotiate the charge down to negligent driving.

Where a plea is the right course, the preparation for sentence is detailed. The guideline judgment assumes full-time custody, so the subjective case has to be built carefully, with the right evidence of remorse, rehabilitation and the circumstances of the offence, and with any appeal point preserved. A driver who has also left the scene faces separate charges for failing to stop and assist, and those are dealt with together.

Frequently asked.

What is the maximum penalty for dangerous driving occasioning grievous bodily harm in NSW?

The maximum under section 52A(3) of the Crimes Act 1900 (NSW) is 7 years imprisonment. For the aggravated offence under section 52A(4) the maximum is 11 years. These are maximum penalties reserved for the worst cases; the actual sentence depends on the facts and the offender.

What counts as grievous bodily harm?

Grievous bodily harm means really serious harm. Section 4 of the Crimes Act 1900 (NSW) includes any permanent or serious disfiguring, the destruction of a foetus, and any grievous bodily disease. Where the injuries fall short of grievous bodily harm, section 52A does not apply and the matter may proceed as negligent driving instead.

What makes dangerous driving occasioning grievous bodily harm aggravated?

Under section 52A(7) the offence is aggravated if, at the time, the driver had a prescribed concentration of alcohol of 0.15 or more, was more than 45 km/h over the speed limit, was driving to escape police pursuit, or was very substantially impaired by alcohol or a drug. Any one of those lifts the maximum from 7 years to 11 years.

What is the difference between dangerous driving and negligent driving occasioning grievous bodily harm?

Dangerous driving under section 52A requires driving that is objectively dangerous, or driving under the influence, and is a serious indictable offence dealt with in the District Court.

Is there a defence to a section 52A charge?

Section 52A(8) provides a defence if the accused proves that the grievous bodily harm was not in any way attributable to the intoxication, the dangerous speed, or the dangerous manner of driving. The accused carries that onus on the balance of probabilities. A charge may also be contested on identity, on whether the driving was dangerous, or on whether the driving was voluntary.

Will you go to jail for dangerous driving occasioning grievous bodily harm?

A full-time custodial sentence is the usual result. The NSW Court of Criminal Appeal has issued a guideline judgment for these offences, most recently restated in Cripps v R [2026] NSWCCA 144. A sentence other than full-time custody is reserved for exceptional cases.
