Alcohol Interlocks

In October 2014 Victoria introduced new alcohol interlock laws.This means anyone whose licence is cancelled for drink-driving (or riding) will have an alcohol interlock fitted into any vehicle they drive (home car, work car, motorbike) once they get their licence back. And the minimum time the interlock will be in place, is six months.

Alcohol interlocks stop vehicles from being started if the driver(or rider) has been drinking. The aim of this technology is to help people separate drinking from driving and are mandatory for all drink-drivers whose licences are cancelled .

Alcohol interlocks are capable of taking photographs - this will helps identify the person who has provided the breath sample each time there is an attempt to start the vehicle. Random tests while driving are also required.

Why Alcohol Interlocks?

Alcohol interlocks are proven to reduce repeat drink driving by up to 64 per cent while they are fitted.

The Victorian Alcohol Interlock Program has already prevented people affected by alcohol from driving their vehicles more than 250,000 times.

Technological advances mean that in the long-term, alcohol interlocks are likely to be a standard feature of all new vehicles in Australia. However, in the mean time, Victoria is leading the way in taking action to reduce the damage caused by drink-driving offenders.

For more information on alcohol interlocks go to the VicRoads website.

Drink driving
Drink-drivers are responsible for 25 to 30 per cent of deaths and 11 per cent of serious injuries on our roads, while repeat drink-drivers make up 20 percent of all drink-drivers detected. Thirty per cent of drink-drivers involved in fatal crashes are repeat offenders.

Only a little bit over you bloody idiot

In 1989 the TAC became involved in mass media road safety advertising launching a series of television commercials showing the tragic results of drink driving. This is when that well known tagline - drink drive, bloody idiot – was born.

From the beginning, enforcement has been a key part of the deterring drink driving. The TAC has funded the purchase of booze buses for Victoria Police random breath tests, breath testers and other equipment to detect offenders.

A major aim of the TAC's drink driving advertising has been to emphasise the reality of  being caught if you are over the limit and the severe penalties that follow.

More recently many people have ignored the dangers of mixing alcohol and driving and have continued to drive with lower, but still illegal, BAC. The excuse used is that driving "only a little bit over .05" is OK. This ignores the fact the risk of a crash is increased as drink drivers are more likely to speed, less likely to wear a seatbelt and less likely to take steps to prevent fatigue.

To combat this,  the TAC introduced the Only a little bit over? campaign in December 2003. Here the key message is - if you drink and drive over the BAC limit, you are breaking the law and endangering the lives of innocent passengers and other road users.

In 1989, the year that the TAC commenced its campaigns, 114 drivers and riders died in road crashes with an illegal blood alcohol concentration. This figure had dropped to 42 in 2009.


Drink driving is one of the biggest killers on Victoria's roads. Almost a quarter of all fatal crashes in Victoria involve a driver or rider with an illegal Blood Alcohol Concentration (BAC).

As drink driving has become more and more socially unacceptable, the TAC's drink drive campaigns are often aimed at low level drink drivers - those who think it is ok to be "just a little bit over" or at the legal limit.

Here are some common questions about drink driving limits.

What is BAC?

Blood Alcohol Concentration (BAC) is a measurement of the amount of alcohol in the body. BAC is measured in grams of alcohol per 100 millilitres of blood. The legal blood alcohol concentration (BAC) limit is 0.05. This means that a driver's body must contain less than 50 milligrams of alcohol per 100 millilitres of blood. A driver's BAC is measured by a simple breath test procedure. Most people find it difficult to gauge their own blood alcohol level as there are so many factors that you need to consider.

These include:

  • the amount of alcohol consumed
  • the period of time over which alcohol is consumed
  • your body mass
  • whether or not you have eaten
  • your fitness levels and
  • the health of your liver.

Because everyone is different, some people need to drink less than the standard hourly recommendations to maintain a BAC level below the legal limit.

How does alcohol affect driving performance?

Driving is a complex task requiring decision making and total concentration. Alcohol affects a driver's ability to be totally in control of his or her actions.

BAC levels and their affects:

  • 0.02 to 0.05 BAC - the ability to see or locate moving lights correctly is diminished, as is the ability to judge distances. The tendency to take risks is increased, and the ability to respond to several stimuli is decreased.
  • 0.05 to 0.08 BAC - the ability to judge distances is reduced, sensitivity to red lights is impaired, reactions are slower and concentration span shorter. At 0.08 BAC drivers are five times more likely to have an accident than before they started drinking.
  • 0.08 to 0.12 BAC - euphoria sets in, overestimation of one's abilities leads to reckless driving, peripheral vision is impaired (resulting in accidents due to hitting vehicles in passing) and perception of obstacles is impaired. Drivers are up to 10 times more likely to have an accident.

What is the current law relating to drink driving?

There are heavy penalties if caught driving under the influence of alcohol or drugs, or a combination of both, or refusing to be tested.
