Blood Alcohol Limit in Victoria
The blood alcohol limit (BAC) in Victoria determines the maximum amount of alcohol you can have in your system while legally driving.
For most fully licensed drivers, the legal limit is 0.05 grams of alcohol per 100 millilitres of blood (0.05%).
If you are caught driving with a BAC above the legal limit, you can be charged with a drink driving offence under the Road Safety Act 1986 (Vic).
Who Must Have a 0.00% BAC in Victoria?
Some drivers in Victoria must have a zero blood alcohol concentration (BAC) at all times. This includes:
- Learner and probationary (P plate) drivers
- Truck drivers operating vehicles over 4.5 tonnes GVM
- Bus, taxi, and commercial vehicle drivers
- Driving instructors and supervisors
- Drivers relicensed after a drink or drug driving offence
These zero-limit rules reflect the higher responsibility and safety risks associated with these categories.
How Is Your BAC Measured?
Police conduct random breath tests (RBTs) throughout Victoria. If a driver tests positive on a preliminary breath test, they are required to take a secondary breath test or blood test at a station or mobile unit.
BAC results are used as evidence in court proceedings for drink driving charges.
Refusing to take a breath or blood test is a serious offence that can lead to:
- Automatic licence cancellation
- Immediate suspension
- Heavier penalties than an over-limit reading
Penalties for Exceeding the BAC Limit
Drink driving penalties depend on your BAC level, licence type, and whether it’s a first or repeat offence.
Common penalties include:
- Licence suspension or disqualification
- Fines and potential imprisonment
- Mandatory alcohol interlock devices
- Court-imposed education or treatment programs
Repeat or high-range offenders often face longer bans and may be required to complete the VicRoads Behaviour Change Program before reapplying for their licence.

What Happens If You’re Caught Above the BAC Limit in Victoria?
If you’re caught driving above the legal blood alcohol concentration (BAC) limit in Victoria, penalties vary depending on your licence type and whether it’s your first or a repeat offence.
Learner & Probationary Drivers
If you record a BAC under 0.05, your licence will be cancelled for three months.
When relicensed, you’ll also be required to install an alcohol interlock device for at least six months, which prevents your vehicle from starting until you pass a breath test.
Fully Licensed Drivers
If you record a BAC between 0.05 and 0.07, you’ll receive a fine and 10 demerit points.
A reading of 0.07 or higher leads to licence cancellation and an interlock requirement for at least six months once you’re relicensed.
Repeat Offenders
Repeat drink driving offences result in licence cancellation and mandatory installation of an alcohol interlock. In more serious cases, courts may impose community-based orders or even imprisonment.
