Drink driving the morning after

Are you breaking the law by driving the morning after?

Did you know?
  Alcohol causes more road crashes than any other single factor in Australia.

1 in 4 
fatal car crashes involve drivers or riders who are above the legal BAC limit of 0.05. In some states of Australia, these account for 1 in 3 fatal crashes.
Your BAC continues to rise up to
3 hours 
after you stop drinking.
If you go out drinking and have a big night out, you may still be over the limit the next day.

Beware the morning after

There are many drivers who think they are obeying the law by not driving home drunk, but are in fact breaking it by getting into their cars the morning after a night of drinking.

On average, the liver breaks down a little less than
1 standard drink per hour.
Alcohol-related crashes are
10x more likely
to happen between
6 to 8am and 2 to 6pm 
on weekends.
Even a small amount of alcohol can affect your ability to drive safely.


It takes longer than most people think for alcohol to pass through the body.

Chances are that if you were drinking until after midnight, alcohol may well still be in your system until mid afternoon the following day, or even later.

Sleeping, coffee, cold showers, and vomiting will not reduce your BAC level. If someone has been drinking the night before, the only cure is time.

Don't risk losing your licence, a heavy fine and endangering yourself and others!


Don't try to estimate your BAC. Measure it.

Personal Breathalyzers

For yourself, friends and family


Workplace Breathalyzers

For alcohol testing in the workplace


Wallmounted Breathalyzers

For work or construction sites, bars, and licensed venues


Ignition Interlock Device

For drivers and fleets




Having a breathalyzer is ever so crucial as drink driving remains one of the biggest killers on Australian roads. In Victoria, around a quarter of drivers killed in road accidents had a BAC of .05 or more.

Testing your BAC before driving can not only save your life and that of others, but also save yourself from heavy penalties. In the interest of road safety, each state has set up penalties for those caught driving under the influence.

Losing your license means that in addition to being unable to drive anywhere, you may be stuck paying a loan for a car you can't use. With most licenses having a 12 point allowance, being caught for even a single drink driving offence is something best avoided.

Additionally, courts now have a higher tendency to order repeat offenders to install alcohol interlock devices in their cars, which can be not only embarrassing but also very expensive with installation, monthly maintenance costs, calibration costs, and more.

Less expensive than a drink driving conviction or an alcohol interlock in your car - an AlcoSense personal breathalyzer. By monitoring your own BAC with a breathalyzer, you can always know with certainty when it is safe for you to start driving again, especially the morning after when you may feel sober but still have alcohol in your system. Get one from AlcoSense for yourself, your mates, or employees to prevent drink driving.
