Working out how many drinks you can have before hitting the road is not as straightforward as it might seem. Several factors, including your body weight, gender, metabolism and the type of drinks you consume, all play a role in your blood alcohol concentration (BAC). To navigate these complexities and ensure you’re driving safely and legally, it’s important to understand both the concept of a “standard drink” and its implications.
What is a standard drink?
You may have heard the old rule that you can have two standard drinks in the first hour and one every hour thereafter, and this will keep you under the legal limit. Unfortunately, this common “rule of thumb” is dangerously oversimplified and misleading. The actual alcohol content in drinks varies widely, making it risky to rely solely on this method.
In Australia, a standard drink contains 10 grams of alcohol. Yet, many alcoholic drinks contain more than one standard drink per serving. The number of standard drinks depends on the type of alcohol and its volume. Here’s a quick rundown of common drinks and their standard drink content:

Determining how many standard drinks you can have before driving involves understanding your body’s response to alcohol and staying within the legal BAC limits. Even if you feel fine, you might still be over the limit, and the consequences of drink driving are severe. Always plan, drink responsibly and make sure you have a safe way to get home.
Overall, due to the number of factors that can influence a BAC, the safest option is to not drive after you’ve been drinking.
