NSW drink-driving information
Drink-driving defence: at a glance
What can “drink-driving defence” mean?
“Drink-driving defence” is a broad description, not a single legal argument or automatic result. In NSW, a review generally begins by identifying the precise allegation and the law applying to it. The matter may involve a prescribed concentration of alcohol (PCA), an allegation of driving under the influence, a refusal or sample issue, or a later licence suspension or disqualification consequence. These are different issues and should not be treated as interchangeable.
The current Road Transport Act 2013 (NSW) is the principal statutory starting point for NSW road-transport offences. The legislation and related penalty information should be checked again before publication or reliance because provisions, commencement dates and consequences can change.
At a general level, a defence review may consider whether the prosecution can prove every required element of the charged offence. It may also examine the wording of the charge, the circumstances and timing of testing, statutory preconditions, identity and driving evidence, admissibility, disclosure and the reliability and consistency of the prosecution material. The existence of a possible checkpoint does not establish that it applies, that evidence is inadmissible, or that a charge will be dismissed.
Common NSW drink-driving allegations
NSW Government material describes PCA categories at a high level as low range, with a BAC of 0.05–0.079; mid range, above 0.08 and below 0.15; and high range, above 0.15. Separate novice and special categories may also apply. The precise category depends on the charge and the applicable law at the relevant time. Current thresholds and consequences should be confirmed against the NSW Government drink-driving penalties information.
Other allegations can include driving under the influence, where impairment is alleged, or failing or refusing to provide a required breath, saliva, blood or urine sample. NSW Government information states that a person asked by police to provide a relevant sample is obliged to provide it and that refusal can itself be charged. That general proposition does not determine whether a particular request, procedure or charge was lawful.
Consequences can include immediate licence action, a court-imposed fine, disqualification, imprisonment exposure for some categories, or alcohol-interlock consequences. The applicable consequence depends on the charge, relevant prior convictions and how the matter is dealt with. No category, penalty or interlock outcome should be assumed without checking current sources.
What happens after a drink-driving charge?
The broad Local Court pathway commonly moves from a charge or notice to a first court date or mention. The person may enter a guilty plea or indicate a not-guilty plea. The Local Court of NSW explains that a guilty plea proceeds to sentencing, while a not-guilty plea leads into a defended hearing process. Available online services, filing requirements and listing information should be checked against current registry instructions.
For a guilty plea, the court may receive an explanation and sentencing material, but an explanation does not guarantee a reduced penalty or any particular result. For a defended hearing, the prosecution case and defence case are dealt with through the applicable hearing process. Whether a matter can properly be defended depends on the charge, evidence, admissibility questions and applicable law; it is not established merely because a person feels sober, has a low personal estimate, has no history, or believes a testing issue may exist.
Neutral preparation checklist
General preparation can help organise information for discussion with a qualified lawyer. It is not a substitute for advice about an individual matter and does not identify what position should be taken.
- Record the court name, court date, courtroom or listing details, and any deadline appearing on the notice or registry material.
- Keep the charge, court attendance notice, police facts, notices and any bail or licence documents together.
- Identify the exact charge wording, alleged date and time, location, vehicle and driving allegation.
- Gather available testing material, including roadside-testing information, evidentiary breath-analysis documents, sample details, certificates and relevant police records.
- Note the sequence of events and times as shown in the documents. Do not assume that a timing issue, including a commonly discussed two-hour issue, automatically invalidates a result.
- Prepare an accurate driving and licence history and identify relevant prior convictions without assuming that being a first offender determines the outcome.
- For sentencing preparation, collect material that may be relevant to the court’s assessment, while recognising that the court decides what weight to give it.
Current-law and evidence cautions
Alcohol readings, sample procedures and court consequences are evidence-and-law questions. Drink counting, feeling under the limit, an absence of bad driving, a medical explanation, alcohol consumed after driving, a low reading or a first offence is not, by itself, a universal defence or entitlement to dismissal. Any such issue requires the relevant evidence and legal analysis.
Historical Judicial Commission publications may help explain earlier sentencing research, but they are not current statistics, current penalty guidance or an outcome prediction. For example, Number 27 is dated March 2003 and must be treated as historical material only. Current law, current government information and current court directions should take priority.
Frequently asked questions
What is a PCA offence in NSW?
A PCA offence alleges that a prescribed concentration of alcohol was present in a driver’s breath or blood. The applicable category and law depend on the charge and relevant circumstances.

The matter may come before the Local Court for a guilty plea and sentencing or proceed through a defended hearing after a not-guilty plea.
Can a drink-driving matter be defended in the Local Court?
