What the Law Actually Says About Drink Driving in NSW
The Road Transport Act 2013 sets out distinct drink driving offences. Understanding which category applies to you is vital, as the difference between low-range and high-range PCA (Prescribed Concentration of Alcohol) changes everything from fines to potential imprisonment.

Automatic Licence Disqualification
Licence disqualification is automatic under NSW law. A first mid-range offence carries a minimum 6-month disqualification, while high-range offences require at least 9 months off the road. For most mid and high-range matters, the Alcohol Interlock Program is mandatory.

What Penalties Apply to Your Drink Driving Charge?
Beyond the initial fine—which can reach $3,300 for a first mid-range offence—a conviction carries ongoing costs. These include increased insurance premiums and employment barriers in the transport sector. Under Section 110 of the Act, prison terms of up to 18 months may apply for high-range offences.
The Interlock Device Requirement
The interlock device costs between $2,200 and $2,500 annually through providers like Guardian Interlock Systems or Draeger Australia. Exemptions are rarely granted and must be argued during sentencing based on severe financial hardship or medical necessity.
How to Challenge the Evidence Against You
The prosecution’s case rests on the reliability of the breath or blood test. Police must follow strict protocols, including the two-hour rule. If a breath test was conducted more than two hours after you stopped driving, the evidence may be inadmissible under Section 138 of the Evidence Act 1995.
Mitigating Your Penalty
Completing a Traffic Offenders Program before your court date demonstrates genuine insight and commitment to change. Character references and a well-drafted apology letter are also essential components of a sentencing mitigation strategy.
