DUI vs. Drug Driving in NSW: Understanding the Key Differences

In New South Wales (NSW), impaired driving—whether due to alcohol or drugs—is a serious offence with severe penalties. These offences endanger road safety and carry legal consequences that can significantly impact a person’s life. While DUI (Driving Under the Influence) and drug driving are often grouped under impaired driving, they differ in testing procedures, legal definitions, and the penalties associated with them. This guide provides a comprehensive breakdown of these offences, their implications, and how legal representation can assist.

Defining DUI and Drug Driving in NSW

What is DUI (Driving Under the Influence)?

DUI refers to driving while impaired by alcohol or drugs, regardless of whether your Blood Alcohol Concentration (BAC) exceeds the legal limit. In NSW, the legal BAC limits are:

• 0.05 for full licence holders.
• 0.00 for learner and provisional licence holders.

Impairment can be determined through behaviour, physical symptoms, or other evidence, even if no alcohol or drugs are detected.

What is Drug Driving?

Drug driving, distinct from DUI, focuses on the presence of illicit drugs in the driver’s system. This offence does not require proof that the driver’s ability to operate a vehicle was impaired—merely testing positive for illegal substances like THC (Cannabis), MDMA, or cocaine is sufficient for charges.

Testing Procedures for DUI and Drug Driving

Alcohol Testing for DUI

1. Breath Tests: Conducted using Breathalysers to measure BAC.
   • Roadside tests are preliminary. If you fail, further analysis, such as blood tests, may follow.
2. Blood Alcohol Concentration (BAC): The measured BAC determines the severity of the offence (low, mid, or high-range).

Drug Testing for Drug Driving

1. Mobile Drug Testing (MDT): NSW police use saliva swabs to test for common illicit drugs.
   • Initial tests take 3–5 minutes.
   • Positive results lead to secondary testing and laboratory analysis.
2. Detection Window: Drugs may remain in your system for days or weeks, depending on various factors like metabolism and frequency of use.

Key Differences Between DUI and Drug Driving

Penalties for DUI and Drug Driving in NSW

DUI Penalties

Penalties for DUI vary based on the BAC level and prior offences:

• Mid-range (0.08–0.149): Larger fines, longer suspensions, interlock device requirements, and potential imprisonment.
• High-range (0.15+): Severe penalties, including longer jail terms and indefinite licence disqualification.

2. Prescription Medications: Some legal medications can impair driving. Check with your doctor.
3. Immediate Driving Ban: A positive roadside drug test results in a 24-hour driving ban, even before secondary test results.

5. Drug Detection Time: Even one-off drug use can result in a positive test days later, depending on the substance.

Legal Defences Against DUI and Drug Driving Charges

Common DUI Defences

1. Challenging Test Accuracy: Question the reliability of Breathalyser or blood tests.
2. Unlawful Stop: Argue that the police had no reasonable grounds for stopping you.

2. Stay Sober: Avoid driving entirely if there’s any doubt about your sobriety.
3. Understand Detection Windows: Be mindful of how long substances can remain in your system.
4. Use Designated Drivers: Rely on a sober friend to drive.
5. Stay Informed: Regularly review updates to NSW traffic laws.

Importance of Legal Representation

Facing DUI or drug driving charges can be overwhelming, but an experienced traffic lawyer can make a significant difference. They can:

• Evaluate the case details for possible defences.
• Negotiate with prosecutors to reduce charges.
• Represent you in court and strive for reduced penalties or dismissal of charges.

Recent Changes in NSW Traffic Laws

1. On-the-Spot Fines: Immediate penalties for low-range drink driving reduce court burdens.
