New South Wales police conduct millions of Mobile Drug Tests (MDT) every year. Unlike drink driving, where there is a legal limit (e.g., 0.05), drug driving laws in NSW operate on a strict "zero tolerance" policy. If any detectable amount of a prescribed illicit drug is found in your system, you can be charged.
A conviction can result in a criminal record and may affect employment, travel, professional licensing, visa applications and other aspects of your life. It also carries mandatory licence disqualification periods and heavy fines.
At NS Criminal Lawyers and Associates, our Sydney drug driving lawyers provide carefully prepared, strategic defence representation. We understand the technicalities of laboratory testing procedures and are dedicated to protecting your licence and your future.
Under the Road Transport Act 2013 (NSW), it is an offence to drive a vehicle with the presence of a prescribed illicit drug in your oral fluid, blood, or urine.
Crucial Point: A "presence" offence does NOT require the prosecution to prove that your driving was impaired. The mere detection of the drug by the laboratory is sufficient to establish the offence.
The standard roadside saliva test screens for four specific illicit substances:
It is important to distinguish a "presence" offence from a Driving Under the Influence (DUI) offence. DUI is a much more serious charge. To prove DUI, the prosecution must establish that you were under the influence of a drug to such an extent that you were incapable of having proper control of the vehicle. DUI carries significantly harsher penalties, including potential imprisonment and longer disqualification periods.
If you are convicted of driving with an illicit drug present in your system, the court must impose a period of licence disqualification.
| Offence | Max Fine | Auto Disqualification | Min Disqualification |
|---|---|---|---|
| First Offence | $2,200 | 6 months | 3 months |
| Second/Subsequent Offence | $3,300 | 12 months | 6 months |
A positive laboratory result is not the end of the road. We rigorously examine the police brief of evidence to identify viable legal defences:
If you plead guilty, our primary goal is often to secure a non-conviction outcome. Under Section 10 of the Crimes (Sentencing Procedure) Act, a Local Court Judge can find you guilty but dismiss the charge without recording a conviction or imposing a licence disqualification. Alternatively, they may impose a Conditional Release Order (CRO) without conviction.
Achieving this requires meticulous preparation. We will guide you in obtaining compelling character references, completing the Traffic Offender Intervention Program (TOIP), and presenting a strong subjective case to the Court.
