The Legal Framework for Drink Driving in NSW
Drink driving offences in NSW are governed by the Road Transport Act 2013, which sets out the prescribed concentration of alcohol (PCA) limits for different driver categories. The Act prohibits driving or attempting to drive a vehicle with a BAC above the legal limit, with offences categorised by BAC ranges: low-range (0.05-0.079), mid-range (0.08-0.149), and high-range (0.15 or above). For some drivers, any detectable alcohol (above 0.00) is illegal.
The legal BAC limits are enforced through random breath tests (RBTs) conducted by NSW Police, using breathalysers to measure alcohol levels. If a roadside test is positive, a more accurate analysis is conducted at a police station. Drug-related driving offences are also covered under the same Act, but this guide focuses on alcohol.
As of August 20, 2025, the BAC limits remain unchanged from previous years, but enforcement has intensified with increased RBTs and harsher penalties for repeat offenders. The laws apply to all vehicles, including cars, motorcycles, and heavy vehicles, with stricter rules for certain categories to ensure road safety.
Why BAC Limits Differ by Category
BAC limits vary to account for experience and responsibility:
- Full Licence Holders: Allowed a small amount of alcohol, recognising moderate consumption for experienced drivers.
- Learner and Provisional Drivers: Zero tolerance to build safe habits during learning phases.
- Special Categories: Zero tolerance for professional drivers due to their responsibility for passengers or heavy loads.
Understanding these limits is essential to avoid charges and maintain road safety.
BAC Limit for Full Licence Holders
For drivers with a full unrestricted licence in NSW, the legal BAC limit is under 0.05. This means you can have a small amount of alcohol in your system, but exceeding 0.05 is illegal. The limit is measured in grams of alcohol per 100 millilitres of blood.
Key Rules for Full Licence Holders
- Low-Range PCA (0.05-0.079): Considered minor but still punishable.
- Mid-Range PCA (0.08-0.149): Indicates moderate impairment.
- High-Range PCA (0.15 or above): Severe intoxication, leading to harsher penalties.
Full licence holders must exercise caution, as even one or two standard drinks can push you over the limit depending on factors like body weight, gender, and food intake. The NSW government recommends using ride-sharing services or public transport after drinking.
Penalties for Full Licence Holders:
- Low-Range:
- Fine: Up to $2,200.
- Disqualification: Automatic 6 months (minimum 3 months).
- Imprisonment: Not typically, but possible for repeat offenders.
- Mid-Range:
- Fine: Up to $3,300.
- Disqualification: Automatic 12 months (minimum 6 months).
- Imprisonment: Up to 9 months (first offence).
- High-Range:
- Fine: Up to $3,300.
- Disqualification: Automatic 3 years (minimum 12 months).
- Imprisonment: Up to 18 months (first offence).
- Mandatory Interlock: Required for high-range offences, costing $2,200–$2,500 annually.
These penalties emphasise the need for a Sydney traffic lawyer to challenge charges or secure reduced outcomes.
BAC Limit for Provisional Drivers
Provisional licence holders (P1 and P2) in NSW must maintain a zero BAC limit (0.00). This strict rule applies for the first three years of driving after obtaining a learner licence, promoting safe habits during the learning phase.
Key Rules for Provisional Drivers
- P1 (Red Plates): First year after learner licence; zero alcohol tolerance.
- P2 (Green Plates): Second and third years; zero tolerance continues.
- Any detectable alcohol (above 0.00) results in a novice-range PCA charge.
Provisional drivers are often young and inexperienced, so the zero limit reduces accident risks.
Penalties for Provisional Drivers:
- Novice-Range PCA (0.00-0.019):
- Fine: Up to $2,200.
- Disqualification: Automatic 3 months (minimum 3 months).
- Imprisonment: Not typically.
- Low-Range (0.05-0.079): Treated as low-range with harsher disqualification for novices.
- Repeat offences escalate penalties, with possible licence cancellation.
A Sydney criminal defence lawyer can help provisional drivers avoid convictions through defences or non-conviction outcomes like section 10 dismissals.
BAC Limit for Learner Drivers
Learner drivers in NSW must adhere to a zero BAC limit (0.00), similar to provisional drivers. This rule applies from the moment you obtain a learner licence until passing the driving test for a provisional licence. Learners must display L-plates and be supervised by a fully licensed driver.
Key Rules for Learner Drivers
- Zero tolerance for alcohol to ensure focus and safety during training.
- Any BAC above 0.00 results in a novice-range PCA charge.
Penalties for Learner Drivers:
- Novice-Range PCA:
- Fine: Up to $2,200.
- Disqualification: Automatic 3 months (minimum 3 months).
- Learner Period Extension: May delay progressing to provisional licence.
- Repeat offences can lead to licence cancellation and re-testing.
Learners are particularly vulnerable to charges during social events, making legal advice from a Sydney traffic lawyer essential to challenge tests or secure leniency.
BAC Limit for Special Categories (Bus/Truck Drivers)
Special category drivers, including those operating heavy vehicles, buses, taxis, or rideshare services, must maintain a zero BAC limit (0.00 or under 0.02 for some). This stricter rule reflects their responsibility for passengers and road safety.
Key Rules for Special Categories
- Heavy Vehicle Drivers: Trucks over 4.5 tonnes GVM must be under 0.00 BAC (section 110, Road Transport Act 2013).
- Bus and Coach Drivers: Zero tolerance to protect passengers.
- Taxi/Rideshare Drivers: Under 0.00 BAC to ensure safe public transport.
- Dangerous Goods Vehicles: Drivers transporting hazardous materials must be under 0.00.
Penalties for Special Categories:
- Special-Range PCA (0.00-0.019):
- Fine: Up to $2,200.
- Disqualification: Automatic 3 months (minimum 3 months).
- Imprisonment: Not typically, but possible for repeat offenders.
- Low-Range (0.05-0.079): Treated as low-range with harsher consequences for professionals.
- Repeat offences can lead to licence revocation and professional bans.
For commercial drivers, a conviction can end careers, making a Sydney criminal lawyer vital to challenge charges or secure non-conviction outcomes.
How Drink Driving Is Detected and Tested in NSW
Drink driving is detected through random breath tests (RBTs) conducted by NSW Police. If positive, a more accurate breath analysis or blood test follows at a police station. Tests must be conducted within 2 hours of driving (section 14, Road Transport Act 2013). Police can also test for drugs if impairment is suspected.
Defences to Drink Driving Charges
If applicable to the case, Common defences include:
- Unlawful Testing: Police lacked grounds for the test (section 36, LEPRA).
- Testing Errors: Breathalyser malfunction or improper calibration.
- Medical Conditions: Conditions like diabetes causing false positives.
- Necessity: Driving to avoid immediate harm (e.g., medical emergency).
- Mental Health Diversion: Under section 14, Mental Health and Cognitive Impairment Forensic Provisions Act 2020, for mental health-related cases.
A Sydney traffic lawyer can challenge evidence or raise defences to secure dismissals or reduced penalties.
