You’ve only had a couple of drinks and you feel fine. You’re thinking of heading home — maybe after giving it another 30 minutes and a glass of water. It’s a familiar story, and one that many Aussies tell themselves after a night out.
But here's the thing: "feeling fine" doesn’t mean you're under the limit. And guessing your blood alcohol concentration (BAC) — even when you’re trying to be responsible — can lead to costly, dangerous mistakes.
The problem with guessing
Alcohol affects everyone differently. Age, weight, metabolism, what you’ve eaten, how fast you drank — they all play a role in how your body processes alcohol. That’s why relying on time or how “okay” you feel isn’t reliable.
We break this down further in our blog on the factors that affect your BAC, including body type, gender, and hydration levels.
Even with a rough idea of how many drinks it takes to reach 0.05%, your BAC might still be higher than expected. You can learn more in our guide on how many standard drinks bring you to .05.
In fact, research has shown that people consistently underestimate their BAC.
And when the legal limit in Australia is just 0.05%, getting it wrong can mean:
- Losing your licence
- Paying thousands in fines
- Endangering lives — yours, your passengers’, and others on the road

Real solution: Certainty you can count on
Instead of guessing, the safest and most reliable way to know your BAC is by using a personal breathalyser — and that’s exactly where Andatech comes in.
A personal breathalyser offers peace of mind, safety, and control over your decision-making. This ensures that you’re not relying on luck or assumptions. You’re getting clear, actionable information that helps you make the right call.
How breathalysers help you stay safe
Rather than waiting and hoping, breathalysers allow you to:
- Check your BAC before getting behind the wheel
- Make smarter choices about driving or waiting longer
- Avoid second-guessing the next day (or worse, explaining it in court)
- Educate others — including your kids, mates, or family members — on how alcohol affects them
Still unsure how long it takes for your BAC to return to zero? We cover that in detail in our blog: How long does it take for your BAC to reach 0.00%?
This isn’t about being paranoid. It’s about taking responsibility in a simple, affordable way.

Take the guesswork out of safe driving
No one ever plans to drink and drive. But it’s often those quiet, “I’m probably fine” moments that lead to split-second decisions with lifelong consequences.
If you drive after drinking — even socially — a personal breathalyser is one of the smartest tools you can have. It's not about being paranoid. It's about being prepared.
