Firstly, everyone is different, but as a guide: Men—No more than 2 standard drinks in the first hour and 1 standard drink each hour after that. Women—No more than 1 standard drink each hour. A standard drink is any drink containing 10 grams of alcohol.
For this reason, there is no prescribed 'wait time' between drinking and driving that guarantees a safe BAC level. Small amounts of alcohol leave the body in urine, breath, and sweat. A healthy liver will break down less than one standard drink per hour, but if your liver is damaged, this can take longer.
Advice to motorists: As a general guide, to stay below the open licence limit of 0.05% BAC: Males can have a maximum of two standard drinks in the first hour, and one standard drink each hour after that; Females can have a maximum of one standard drink in the first hour, and one standard drink each hour after that.
allow at least one hour for your body to process each standard drink. So, for example, if you've had five full strength pots of beers or four glasses of wine, you'd need to wait at least six hours before thinking about getting behind the wheel.
The liver is the main body organ that removes alcohol from your bloodstream. Alcohol is processed at a fixed rate. It generally takes about one hour to break down the alcohol content of one standard drink.
The general rule of thumb is that 2 standard drinks in the first hour will raise your BAC to 0.05%, and 1 standard per hour thereafter will maintain that level. To do a quick calculation of whether you are over 0.05% BAC, simply take the number of hours since your first drink and add 1 to it.

A BAC of 0.02 can be reached after the consumption of only one standard drink (a middy of beer, a nip of spirits or a small glass of wine). Drivers subject to a 0.02 limit should not drink any alcohol before driving.
Laws that apply anywhere in Australia
Drink driving – you're breaking the law if you drive and your blood alcohol concentration equal to or more than 0.05. If you're on a learners or provisional licence, your BAC must be zero.
A general rule of thumb is not to drive if you feel even the slightest effects of drinking. If you must take a drink or two, remember that our bodies metabolize one drink per hour. You might feel like you're good to go if you wait a few hours after drinking, especially if you dilute the alcohol by drinking water.
Generally, a breathalyzer test can test positive for alcohol for up to 12 hours after consuming one alcoholic drink. The average urine test can also detect alcohol 12-48 hours later. If your BAC is 0.08, it will take approximately 5 hours to metabolize the alcohol completely before you can become “sober” again.
Alcohol detection tests can measure alcohol in the blood for up to 6 hours, on the breath for 12 to 24 hours, urine for 12 to 24 hours (72 or more hours with more advanced detection methods), saliva for 12 to 24 hours, and hair for up to 90 days. The half-life of alcohol is between 4-5 hours.
In general, you shouldn't drink alcohol every single day. However, according to the alcohol consumption guidelines, it's safe for women to drink one glass of wine per day and safe for men to drink two glasses of wine per day. One glass is considered to be 5oz at 12% ABV.
What most people do not realize is that alcohol can remain on your breath for up to 12 to 24 hours after your last alcoholic drink. Therefore, you could easily “fail” a breathalyzer test the morning after consuming alcohol.
According to the Mayo Clinic, for instance, having one or two drinks a day has been shown to lower the risk of diabetes and improve cognitive functioning. Previous studies have also concluded that drinking up to two glasses of red wine a day can help antioxidant levels and protect heart health.
CASUAL BOTTLE OF RED/WHITE WINE:
Drinking a casual bottle of red or white wine will have you off the road for 8 hours after your final glass (15 hours for two bottles and 38 hours for 3 bottle).
Our handy standard drinks guide can help: Spirits 40% alcohol, 30ml nip. Wine 13% alcohol, 100ml average serving. Sparkling wine 13% alcohol, 100ml.
It's safe to stick to a standard of no more than three glasses of wine per day, but limiting alcohol consumption may also promote more healthy living habits.
Technically there is no federal limit on how much alcohol can be brought in for personal use, but US Customs and Border Protection (CBP) will likely flag you if you're carrying more than a case (e.g. 12 bottles of wine) in your luggage.
Levels can range from 0% (no alcohol) to over 0.4% (a potentially fatal level).
A cold shower, fresh air, exercise, or black coffee will not help sober a person up. Time is the only thing that will remove alcohol from the system (about an hour per standard drink).
For example, if the BAC is 0.05%, that means the person has 50 milligrams of alcohol in 100 millitres of blood. How much and how fast a person drinks, their body weight and type, and how much food they have eaten affects BAC.
No matter how many drinks it takes to reach 0.05 BAC, people at this level are too impaired to drive safely. The public supports levels below 0.08 BAC.
Eating and drinking
Eating before, during, and after drinking can help slow the absorption of alcohol into the bloodstream. Drinking plenty of water can also assist with dehydration and flushing toxins from the body.
