Can you refuse a breath test in NSW? Many drivers ask this question after being stopped by police. Some believe refusing a breath test will prevent police from proving they were over the legal alcohol limit. However, refusing to comply with police requirements can itself result in serious criminal offences and significant penalties.

If you have been charged with refusing a breath test, understanding your legal obligations and obtaining legal advice early is important before attending court.

An experienced Drink Driving Lawyer Sydney can explain your legal options and represent you throughout your matter.

What Is the Difference Between a Breath Test and a Breath Analysis?

A roadside breath test is the preliminary test conducted by police to determine whether alcohol may be present.

If the roadside test indicates alcohol, or police otherwise require it, you may be taken for a formal breath analysis using an approved instrument.

Failing or refusing either procedure may result in criminal charges depending on the circumstances.

Is It an Offence to Refuse a Breath Test?

Yes.

Under the Road Transport Act 2013 (NSW), motorists are generally required to comply with lawful directions from police to undergo breath testing and, where required, breath analysis.

Refusing without a lawful excuse may constitute a criminal offence carrying significant penalties.

Whether an offence has been committed depends on the particular facts of the case.

What Happens If I Refuse?

If police allege you refused to provide a breath sample, you will generally receive a Court Attendance Notice requiring you to appear before the Local Court.

Depending on the circumstances, police may also suspend your driver’s licence immediately.

What Penalties Can Apply?

The penalties available depend on:

  • the particular offence alleged;

  • whether it is a first or subsequent offence;

  • the applicable legislation;

  • the circumstances of the case.

Depending on the matter, the court may impose:

  • a fine;

  • licence disqualification;

  • participation in the Alcohol Interlock Program where applicable;

  • a community-based sentence;

  • imprisonment in more serious cases.

Will I Lose My Licence?

Many people charged with refusing a breath test are concerned about whether they can continue driving.

Licence consequences depend on the offence and the orders ultimately made by the court.

Can I Defend the Charge?

Every case depends on its own facts.

Whether a defence is available depends on matters such as:

  • whether police acted lawfully;

  • whether the statutory procedures were followed;

  • whether there was a lawful excuse for non-compliance;

  • the evidence relied upon by the prosecution.

Legal advice should be obtained before deciding how to proceed.

Should I Plead Guilty?

Whether you should plead guilty depends on the circumstances of your case and the available evidence.

Before entering any plea, it is important to obtain legal advice and understand the prosecution case.

Will I Receive a Criminal Record?

Whether a conviction is recorded depends on the offence, the applicable legislation and the sentence imposed by the court.
