You’re out with your friends for dinner. A bottle of wine is ordered and shared among everyone.
You refill your glass, thinking that you'll still be okay to drive.
The bad news is that you won’t.
Believe it or not, just 75ml of wine constitutes a unit of alcohol – and according Arrive Alive, you should drink no more than one unit of alcohol every hour if you’re driving.
Or better still – don’t drink and drive at all.
