Morning after drink-drive calculator

Use the calculator below, courtesy of the Morning After drink-drive campaign, to find out roughly how long it can take to sober up from different amounts of alcohol.

Please note, this calculator is not intended to help you work out how much you can drink on a night out before driving home. If you are drinking even one alcoholic drink, you should leave the car at home and make alternative arrangements.

To download the calculator as an app, visit the Google Play Store or the App Store.
