In brief
In NSW, drink driving is prosecuted as a prescribed concentration of alcohol (PCA) offence. There are three main ranges: low range (0.05–0.079 BAC), mid range (0.08–0.149), and high range (0.15 and above). Penalties include fines, licence disqualification, and imprisonment. A specialist drink driving lawyer can advise on penalty minimisation, Section 10 dismissals, hardship submissions, and the interlock program.
What most people call “drink driving” or “DUI” is prosecuted in NSW as a prescribed concentration of alcohol (PCA) offence. The specific reading on your breath or blood test determines the charge, the minimum penalty, and the options available to you in court. Getting advice from a drink driving lawyer before your court date (not after) is the single most important step you can take.
This guide explains how NSW’s PCA offence framework works, what the courts can impose, and what a specialist lawyer can do to protect your licence, your record, and your livelihood.
What PCA means in NSW law
PCA stands for prescribed concentration of alcohol. It refers to the concentration of alcohol in a person’s blood, breath, or urine, compared to the limits set by law. When people talk about a “blood alcohol reading” or “BAC,” they are generally referring to the same measurement.
Under the Road Transport Act 2013 (NSW), it is an offence to drive a motor vehicle with a PCA at or above the relevant limit for your licence category. The three limits that apply to most drivers are low range, mid range, and high range. There are also special and novice ranges that apply to learners, provisional drivers, and certain professional or restricted-licence holders, for whom a zero limit applies.
Low range PCA: 0.05 to 0.079
A low range reading is the most common PCA charge. For a first offence, the maximum penalty is a fine of $2,200 and an automatic licence disqualification of 6 months. The minimum disqualification period is 3 months.
For a second or subsequent PCA offence within 5 years, the maximum fine increases to $3,300 and the minimum disqualification rises to 6 months, with a maximum of 12 months.
Low range is the category where a Section 10 dismissal or a conditional release order without conviction is most available, though neither is guaranteed. A magistrate considering a Section 10 will weigh your driving history, the circumstances of the offence, and the character evidence you put before the court. A borderline low range reading, a clean record, and strong character references can make a real difference.
The key word is presentation. The same facts presented poorly produce a worse outcome than the same facts presented with care and relevant legal submissions.
Mid range PCA: 0.08 to 0.149
A mid range reading is treated considerably more seriously. For a first offence, the maximum penalty is a fine of $2,200, up to 9 months imprisonment, and a licence disqualification of between 6 months and 12 months. Courts can also impose an interlock condition (see below).
A second or subsequent mid range offence within 5 years carries a maximum fine of $3,300, up to 12 months imprisonment, and a disqualification of between 12 months and 3 years.
At mid range, a conviction is more likely than at low range, but not inevitable. The disqualification period sits on a spectrum between the statutory minimum and maximum, and how your matter is presented to the magistrate (through submissions, supporting documents, and character evidence) directly affects where on that spectrum your penalty falls.
High range PCA: 0.15 and above
A high range reading is the most serious PCA offence. For a first offence, the maximum penalty is a fine of $3,300, up to 18 months imprisonment, and a disqualification of between 12 months and 3 years. The court must impose an interlock condition unless there are exceptional circumstances.
A second or subsequent high range offence within 5 years carries a maximum fine of $5,500, up to 2 years imprisonment, and a disqualification of between 2 years and 5 years.
High range matters are heard in the Local Court but treated with real seriousness. A reading significantly above 0.15, or the presence of aggravating factors (a collision, children in the vehicle, a record of prior traffic offending) increases the risk of a custodial penalty. Early, skilled legal representation is not optional at this level.
Novice and special range PCA: zero tolerance
For learner, P1, and P2 licence holders, and for certain professional drivers and those on restricted licences, any detectable alcohol is an offence (novice or special range). These ranges apply a zero-tolerance standard: any reading above 0.000 constitutes an offence.
The penalties are lower than the three main PCA ranges, but the consequences for a young driver (particularly the impact on a provisional licence) can still be significant.
Immediate suspension at the roadside
For mid and high range PCA readings, NSW Police have the power to suspend your licence immediately at the roadside. This is an administrative action, separate from any court process, that takes effect the moment it is imposed.
You cannot drive at all from the point of immediate suspension, not to your destination, not home, and not to your next court date. Driving during a suspension period is a separate offence carrying significant penalties.
For low range readings, immediate suspension is not automatic, but police retain a discretionary power to suspend your licence where they consider it necessary for road safety.
The interlock program
For mid and high range offenders, and for repeat PCA offenders, the court must generally impose an alcohol interlock condition as part of the disqualification. An interlock is a device fitted to a vehicle that requires the driver to provide a clean breath sample before the engine will start.
The interlock period begins after the disqualification period ends and continues for a specified term. During this period, you can only drive a vehicle fitted with an approved interlock. Failing to participate in the interlock program, or tampering with the device, is a further offence.
In some circumstances, the court can exempt a person from the interlock requirement. Whether an exemption is available depends on the specific facts and the representations made to the court.
What happens in court
Most drink driving matters are dealt with in the Local Court. You will receive a court attendance notice specifying the court location and date. The matter is heard before a magistrate; there is no jury.
If you intend to plead guilty, it is still worth getting legal advice before your court date. The way a guilty plea is presented (the supporting character references, the submissions on your personal circumstances, the hardship arguments) can significantly affect:
- Whether you receive the minimum or maximum disqualification period
- Whether a work-related vehicle exemption or hardship argument is accepted
- Whether a Section 10 dismissal or conditional release order without conviction is available
- Whether an interlock condition is imposed
If you intend to contest the charge, the process is more involved. Technical defences exist in some cases, challenges to the testing equipment, procedural irregularities in how the breath test was administered, or questions about whether the “two-hour rule” was properly applied. These are fact-specific and require careful assessment.
The South Coast context: hardship and limited transport
The far south coast of NSW has limited public transport. Losing your licence for 6 to 12 months is not an inconvenience for most people in Nowra, Batemans Bay, Narooma, Merimbula, Eden, or Bega; it means losing employment.
Courts in NSW Local Courts are aware of regional hardship, and submissions based on the absence of public transport alternatives and the employment consequences of a lengthy disqualification can carry real weight. These submissions need to be made properly, with supporting evidence, to be effective.
If your licence is your livelihood (whether you drive to work, for work, or rely on a vehicle to reach any employment at all), this needs to be part of your case.
Drink driving charges in Canberra (ACT)
NSW and ACT drink driving law differ. In the ACT, drink driving is prosecuted under the Road Transport (Alcohol and Drugs) Act 1977 (ACT). The general PCA framework is similar, but the specific offence categories, penalties, and procedures differ from NSW.

What a drink driving lawyer can do
A specialist drink driving lawyer reviews the facts of your matter, advises on the realistic range of outcomes, and puts the best possible case before the magistrate. Specifically:
- Pre-court advice: understanding your charge, your options, and what supporting material will help
- Breath test challenges: assessing whether any procedural or technical defences apply
- Plea preparation: character references, employer letters, transport hardship evidence
- Sentencing submissions: targeting the minimum disqualification period and addressing interlock
- Section 10 applications: presenting the case for a dismissal or non-conviction order where appropriate
- Hardship submissions: regional transport context and employment impact
A drink driving charge handled by a specialist consistently produces better outcomes than the same charge handled by someone who does not appear in traffic courts regularly.
