Alcohol and driving

It is safest to avoid drinking alcohol if you need to drive or operate heavy machinery.
If you do drink, the following is a general guide for staying under 0.05 BAC (Blood Alcohol Concentration): Men – no more than two standard drinks in the first hour. After that, one standard drink per hour for a maximum of three hours. Women – no more than one standard drink in the first hour. After that, one standard drink per hour for a maximum of three hours.These are guidelines only. The rate of alcohol absorption in the body varies depending on several factors including body size, gender, body fat and amount of food in the stomach. If in doubt, don't drink if you are going to drive or operate heavy machinery.
Learner and probationary drivers, and drivers of trucks, buses, trams and trains must maintain a zero blood alcohol limit.
Remember that alcohol takes time to leave the body. You may still have alcohol in your body several hours or even the day after drinking
