About When Can I Drive?
When Can I Drive? is a free BAC (blood alcohol concentration) calculator and drink tracker. Record your drinks to explore how your estimated alcohol level may rise and fall over time.
Choose a country or region and see its drink-driving limit alongside an estimated alcohol timeline. Explore absorption, elimination and estimated times when the calculated level may fall below the selected limit.
FEATURES
• Visual BAC timeline and estimated rise and decline
• Country and regional driving-limit reference line
• Red, amber and green estimated risk zones
• Log beer, wine, spirits and cocktails; save favourites
• Optional personal profile and detailed alcohol estimates
• Dark mode; Android phones and tablets
Includes limit references for the UK (including Scotland), Europe/EEA, Switzerland, Norway, Canada, New Zealand, South Africa, Japan and Hong Kong.
FREE TO USE
No subscription or hidden fees. Small adverts help support development.
IMPORTANT SAFETY NOTICE
All results are estimates and vary between individuals. This app cannot determine whether you are legally or medically fit to drive. An estimate below a legal limit is not proof that driving is safe. If you have consumed alcohol, the safest option is not to drive.
