What is the Offence of Refusing a Breath or Drug Test?

In Victoria, refusing to undergo a breath test, saliva test, or blood test when lawfully requested by police is a serious offence under the Road Safety Act 1986 (Vic). The law imposes strict penalties for refusal, often harsher than those for drink or drug driving itself.

Police have the power to conduct roadside tests for:

• Alcohol (breath test or blood test)
• Drugs (saliva, blood, or impairment test)

Refusal to comply can result in an automatic licence disqualification and substantial fines.

What the Prosecution Must Prove

To secure a conviction for refusing a breath or drug test, the Prosecution must establish:

1. You were driving or in control of a motor vehicle — This includes being in the driver’s seat with the keys in the ignition.
2. Police lawfully requested a test — The request must have been made in accordance with the law (e.g., within three hours of driving).
3. You refused to comply — This includes outright refusal or failing to provide a sufficient sample without a valid reason.

• Licence Disqualification — Mandatory for all offences.
