Drink driving FAQs

Important information-only notice

This page is general information only, not legal advice, and is not a substitute for advice about a particular charge, notice, test result or court date. A testing issue, prescription use, delay, low reading, lack of impairment, medical cannabis, need for a licence or procedural complaint does not automatically defeat a charge or guarantee a particular outcome. Current legislation, notices, penalty tables, eligibility rules and court directions should be checked before action is taken.

Common NSW drink-driving categories

NSW recognises several alcohol-related driving categories, including novice or special-range offences and low-, mid- and high-range prescribed concentration of alcohol (PCA) offences. The relevant category depends on the allegation and applicable law. A BAC range or label should not be treated as a conclusion about a person’s charge without checking the charge wording and current legislation.

Published consequences can include fines, licence suspension or disqualification, alcohol-interlock requirements and, for some offences, imprisonment exposure. The applicable consequence can depend on the offence category, relevant prior convictions and how the matter is dealt with. Amounts, periods and interlock rules can change, so use the current NSW drink-driving penalties information together with the legislation.

Drug presence, impairment and combined allegations

A drug-presence allegation and driving under the influence are different legal issues. NSW law prohibits driving with specified illicit drugs present in oral fluid, blood or urine, while a separate influence offence concerns driving while affected by alcohol or a drug. Presence alone should not be described as proof of impairment.

Transport for NSW describes mobile drug testing as oral-fluid screening for four commonly tested illicit drugs: cannabis or active THC, MDMA, cocaine and methamphetamine. A positive roadside screen is followed by further testing, and a charge arises after laboratory confirmation of presence. A positive roadside result may also lead to a current 24-hour driving prohibition, subject to official operational guidance. See NSW drug-driving penalties, drug driving and medical cannabis and combined drink-and-drug driving.

Testing, samples and immediate suspension

Police may require a driver to provide requested saliva, blood or urine samples under the applicable law. Refusal can itself be charged and has separate consequences. A roadside screen, laboratory result or testing complaint is not by itself a universal defence. The charge, statutory elements, police powers, timing, sample handling, laboratory confirmation and admissible evidence may all be relevant issues to investigate.

Police can immediately suspend a licence for specified alcohol- or drug-driving allegations, and the Road Transport Act provides a Local Court appeal pathway. Lodging an appeal does not itself stay the suspension, and the applicable requirements must be checked against current legislation and court information. For related process information, see licence suspension appeals, licence disqualification and the alcohol interlock program.

Notices, court attendance and pleas

Some matters begin with a penalty notice; others proceed by a Court Attendance Notice. A Court Attendance Notice states the alleged offence, the court and when and where to attend. Many road-transport proceedings are dealt with summarily in the Local Court, subject to the legislation. Court staff can provide procedural information, but not legal advice.

A guilty plea generally proceeds to sentencing: the prosecutor presents the facts and relevant record, the person may provide information for sentencing, and the judicial officer decides the penalty. A not-guilty plea leads to a defended-hearing process, which is usually listed for another date. Neither a plea, explanation nor preparation material guarantees a particular sentence or result. See guilty plea and court preparation and the NSW Local Court process.

Neutral preparation checklist

• Record the exact wording of the charge, notice or Court Attendance Notice, including the listed court and date.
• Keep official documents about any roadside test, sample request, laboratory result, suspension or prohibition.
• Organise relevant licence and driving-history material, while checking what the current law treats as a prior offence.
• Note questions about timing, testing sequence, sample handling, statutory powers and disclosure for qualified advice.
• If attending for sentence, assemble relevant personal and practical material without assuming it will produce a particular penalty.
