Mornings after
Your liver processes alcohol slowly (0.015% BAC/hr), sleep & coffee won't speed it up. Morning-after BAC can still exceed 0.00%. Always test before driving!

Myth vs Fact
What most P-platers get wrong about drink driving
-
A mate says A coffee or a cold shower sobers you up faster.
The reality Nothing speeds up how your body processes alcohol. Only time does — roughly 0.015% BAC per hour. -
A mate says If you feel fine, you're fine to drive.
The reality Impairment starts well before you feel it. A P-plater over 0.00% is over the limit, however sober they feel.
-
A mate says Sleeping it off will bring you back to zero by morning.
The reality A big night can easily leave you over 0.00% at breakfast. Test before you drive — not before you sleep.

What P-platers say about checking before they drive
Very happy with the productI purchased for my 18 year old daughter Service was great from Andatech and had my order delivered to me within 24 hours.
Easy To UseHad our Breathalyser for a couple of months now. Small, lightweight & easy to use. 3 decimal places is great for our kids on P Plates. What we love is that they didn't know if they had alcohol in their system or not, just guessed, and we had to pressure them not to drive. Now they just pick it up, use it and move forward with whatever the reading is. Peace of mind for us too, knowing they are right to drive. Highly recommend - Thank you
Review for AlcoSense VerityThe andatech pocket or purse sized breathalyser gives me and my three daughters a better understanding of our personal alcohol consumption and our blood alcohol level. We all feel empowered to be safe before driving and can share our knowledge with friends if required given the disposable mouthpieces.
