Refusing a Breath or Blood Test in Victoria: How It Affects Your Relicensing

Saying no to police when they ask for a breath test alcohol reading doesn't make the problem go away. In fact, it usually makes things worse. In Victoria, refusing a breath test is treated as seriously as the worst drink-driving offences, and it pushes you straight into the toughest relicensing pathway available. If you're trying to work out what happens next, here's what the law says and what it means for getting back behind the wheel.

Quick Answer

• Refusing a breath test alcohol screening is a criminal offence in its own right under the Road Safety Act 1986 (Vic), separate from drink-driving itself.

• A first offence carries a mandatory minimum two-year licence disqualification, regardless of whether you'd actually been drinking.

• You'll be required to complete an Intensive Drink and Drug Driver Program before you can apply to get your licence back.

• Relicensing also means installing an alcohol interlock, usually for a minimum of six months, plus a zero-BAC condition for years afterwards.

• A second or subsequent refusal extends the mandatory disqualification to 4 years and may include imprisonment.

  
  

Is It an Offence to Refuse a Breath Test in Victoria?

Yes. Under section 49 of the Road Safety Act 1986 (Vic), refusing to undergo a preliminary breath test when a police officer lawfully requires it is a standalone offence, separate from any drink-driving charge. The same applies to refusing the follow-up evidentiary test at a police station or "booze bus," as well as to refusing a blood sample when it is properly requested.

Police don't need to prove you were over the limit to convict you; they only need to show the request was lawful and that you didn't comply.

That's an important distinction for anyone wondering whether silence, hesitation, or simply not blowing properly counts. It usually does. Courts have found that going through the motions without properly complying (stopping early, not blowing hard enough, or walking off before testing is finished) can still amount to refusal.

Can You Refuse a Breath Test for Any Reason?

There's no general right to decline. The only real exceptions concern timing and process. Police generally can't require a test more than 3 hours after you were driving, and the request itself has to be made properly under the Act. 

Outside those narrow circumstances, refusing a breath test alcohol request because you're worried about the result, or because you've had legal advice elsewhere telling you it's a clever move, tends to attract harsher consequences than simply blowing over the limit would have.

What Happens After Refusing a Breath Test: Penalties and Relicensing

The fines for refusal aren't enormous on paper; usually up to 12 penalty units for a first offence. What changes everything is the licence consequence. Under section 50 of the Road Safety Act 1986 (Vic), the court must cancel your licence and disqualify you for a set minimum period when you're found guilty of a refusal offence, and that minimum doesn't shrink just because no alcohol reading was ever recorded.

For a second or later offence, the maximum fine jumps sharply and imprisonment becomes a real possibility.

Refusal cases are routed differently for behaviour change programs. Where a standard first-time drink-driving offence might only require the regular drink driver program, refusing a breath test or alcohol test places you in the same category as repeat offenders and high-range readings, meaning you'll need to complete the longer, more involved BCP program before VicRoads or the Department of Transport and Planning will consider relicensing you.

Getting Your Licence Back After Refusing a Breath or Blood Test

Once your disqualification period ends, relicensing isn't automatic. You'll need to complete the Intensive Drink and Drug Driver Program, have an alcohol interlock installed once you're approved to drive again, and in some cases, provide further reporting to the court (such as a licence eligibility order).

The interlock itself usually stays in place for a minimum of six months, and depending on when your offence happened, you may also need to maintain a zero blood alcohol concentration for three years after the interlock is removed. If a genuine medical condition means an interlock isn't workable for you, an alcohol interlock exemption application is worth discussing with a specialist provider, though it requires a formal alcohol assessment and isn't granted lightly.

The Right Support To Get You Back On The Road

None of this is meant to add to what's already a stressful situation. The relicensing process after a refusal charge has many moving parts, and getting any one wrong can add months to it.
