Getting a driver’s licence is one of the biggest milestones in a young person’s life. But for parents, it often comes with a whole new set of worries.
Whether it's parties, peer pressure, or inexperience, the risks are real — especially when alcohol is involved. That’s why one small device could play a huge role in shaping safe, lifelong habits: a personal breathalyser.
The harsh reality: Teen drivers and alcohol
In Australia, drivers on L or P plates are subject to a zero blood alcohol concentration (BAC) limit. That means no tolerance for alcohol — even a small amount could result in a fine, licence suspension, or worse.

And yet, some teens may still take chances or rely on guesswork. They might feel fine or think “just one drink” is okay — but without testing, there’s no way to know for sure. That uncertainty can be incredibly dangerous.
Many don’t realise how little it takes to be over the limit. Our guide on how many standard drinks will get you to 0.05 breaks down the numbers — and they’re lower than you’d think. Plus, factors like body type, gender, sleep, and food intake all play a role, as outlined in our blog on the factors that affect BAC.

Why guessing your BAC is a dangerous mistake
Young drivers often underestimate how much alcohol can affect them — both physically and legally. And while they might feel in control, the law doesn't work off feelings.
Without a breathalyser, they’re left guessing — and guessing is risky. A poor decision behind the wheel can lead to serious consequences not just for them, but for others too.

How a personal breathalyser builds better habits
Giving your teen a personal breathalyser is more than just about checking their BAC — it’s about giving them the tools to make smart, confident decisions.
It encourages accountability, gives them control over their actions, and fosters responsibility. Instead of relying on you to make the call, they learn how to make it themselves — safely.
Andatech’s AlcoSense personal breathalysers are compact, certified to Australian Standards, and designed for everyday use. Whether kept in a glove box, pocket, or bag, they make testing quick, easy, and stigma-free.
