What are the rules for driving with a blood alcohol of 0.05 in Australia?

Blood Alcohol Limits for Driving in Australia

In Australia, the legal blood alcohol limit (BAC) for driving depends on your licence type:

• Standard licence holders: Maximum 0.05% BAC
• Learner and provisional licence holders: Zero tolerance – 0.00% BAC
• Heavy vehicle and bus drivers: 0.02% BAC

What Happens if You Drive at 0.05?

If you have a standard licence and your BAC is exactly at or below 0.05%, you are legally allowed to drive. However, if you exceed 0.05%, you commit an offence.

Penalties for Exceeding 0.05

Penalties vary by state but typically include:

• Fines (often $500–$3,000+)
• Licence suspension (3–12 months for first offence)
• Criminal record
• Mandatory alcohol education programs
• Higher penalties for repeat offences or significantly higher BAC levels

Important Safety Note

Even at 0.05%, your driving ability is affected. Reaction time, concentration, and judgment are impaired. Many safety experts recommend zero alcohol when driving.

Testing

Police can conduct random breath tests (RBTs) on any driver. Refusing a test is also an offence.
