Drink Driving Penalties in Victoria – Important Updates

Drink driving charges can be tricky to navigate, as there are various offences and penalties that fall under the umbrella of ‘drink driving’. Drink driving is a serious offence in Victoria and carries mandatory penalties. There are several different drink driving offences depending on your Blood Alcohol Concentration (BAC) reading and your licence type.[1]

Prescribed Concentration of Alcohol (PCA) Offence

This offence is where you drive with a Blood Alcohol Concentration (BAC) in excess of 0.05.[2] This blood alcohol level is measured through either a sample of exhaled air or a blood test.[3] Zero BAC applies to learner (‘L-Plate’) and provisional (‘P-Plate’) drivers, truck drivers, and those with a nil alcohol licence condition. The most common method of analysis is through a roadside ‘breath test’ to measure the level of alcohol in exhaled air. The Police must prove that you:

  • Operated a motor vehicle; and
  • Had an excess of the prescribed concentration of alcohol.

It is an offence to refuse to provide a sample breath test or refuse to stop at a testing station.[4]

Current Drink Driving Penalties

Currently, the penalties for driving in excess of the 0.05 blood alcohol limit vary, according to what level is recorded on the sample of breath or blood sampled and licence level. If alcohol is found in the system, you can have your licence cancelled, be disqualified from holding a licence for a period of time and be required to complete a behaviour change program before your licence is restored. Alcohol interlock devices are mandatory for all drink driving offenders.[5] The table below highlights the current minimum penalties imposed for drink driving offences.

Are There Any Defences?

There are some avenues to defend your alleged drive with a prescribed concentration of alcohol charge which relate to the accuracy of your BAC reading. Positive roadside BAC tests are always backed-up by a subsequent test at the Police Station. Challenging the accuracy of the BAC reading is possible if there are major discrepancies between the roadside test and that taken at the Police station or if there are grounds to question the calibration of the breath analysis device. However, these defences are technical and difficult to establish. If the test was taken more than 3 hours after you operated a vehicle, the test cannot be used as evidence that you were intoxicated at the time of operating a motor vehicle.

You may also have a defence of a reasonable mistake relating to the charge.

We strongly recommend contacting an experienced criminal lawyer as soon as possible if you have been charged with a drink driving offence.
