After drinking alcohol<\/span>, your blood alcohol concentration<\/span> (BAC<\/span>) rises. Your alcohol <\/span>metabolism<\/span> rate<\/span> determines how long it will take for you to become sober and legal to drive again. The police can measure your BAC<\/span> levels<\/span> to decide whether to charge you with a DUI<\/span>.<\/p>\n\n <\/div>\n\n\n\n

Have you ever wondered why some people seem to \u201cget drunk” faster than others? Or how some people \u201chold their liquor” better? The answer lies in understanding what it means to metabolize alcohol.<\/p>\n

This can be confusing, especially if you’re facing a\u00a0driving under the influence<\/a> (DUI) charge or trying to avoid one. Even a single drink can impair your driving ability. Learn how to stay safe.<\/p>\n

Below, you can learn about the concept of alcohol metabolism rates, blood alcohol levels, and how they relate to DUI charges. But every DUI case is different. Get advice from a local DUI defense attorney<\/a> if you were arrested and charged with drunk driving.<\/p>\n

Driving Under the Influence<\/h2>\n

Driving under the influence of alcohol or drugs is a significant problem in the United States. As such, state laws generally treat drunk driving as a criminal offense.<\/p>\n

Drunk driving is a serious crime with severe consequences. You face driver’s license suspension, hefty fines, and probation, even if no injuries occur. You will likely have to perform community service and undergo substance abuse education and treatment. Your auto insurance costs will spike.<\/p>\n

Many states will require you to install an\u00a0ignition interlock device<\/a>\u00a0in your vehicle. This device uses a breath test to ensure you cannot start your car if you have any alcohol in your system.<\/p>\n

Legal Limit for DUI<\/h3>\n

The \u201clegal limit<\/span>\u201d refers to the amount of alcohol metabolites<\/a> <\/span>in a person\u2019s blood. This is your blood alcohol content or blood alcohol concentration<\/a>\u00a0(BAC).<\/p>\n

Chemical tests measure your BAC, either by a blood test, a urine test, or a breath test. Officers may have you perform\u00a0field sobriety tests<\/a>\u00a0as well. Law enforcement conducts these tests at the time of your arrest or within two hours.<\/p>\n

In the U.S., the BAC limit is 0.08% in all states except Utah. Utah is the only state that has adopted a 0.05% per se<\/a> limit for blood alcohol concentration. You are per se under the influence of alcohol if your BAC is at your state’s legal limit or greater. Per se intoxication means the prosecution doesn’t need to provide additional evidence of your impairment.<\/p>\n

In many states, you can get arrested on a drunk driving charge even if your BAC is below the legal limit when you appear intoxicated. Of course, this doesn’t refer to being under the influence of\u00a0illegal or prescription drugs<\/a>.<\/p>\n

If you are under the legal drinking age, you face arrest if a police officer finds any amount of alcohol in your system. These \u201czero tolerance” laws<\/a> are present in all 50 states.<\/p>\n

How Many Drinks Until I Reach the Legal Limit?<\/h2>\n

There isn’t a magic number, unfortunately. When you consume an alcoholic beverage on an empty stomach, 20% to 30% of the alcohol gets absorbed into your blood through the walls of your stomach relatively quickly. It does not have to undergo digestion, like food, to enter your bloodstream. The remaining alcohol moves to your small intestine, where it is further absorbed. If you have food in your stomach, this will slow the alcohol absorption rate.<\/p>\n

Alcohol affects your central nervous system. Even one drink can affect your coordination, slowing your response time and movements. You can feel drowsy and have trouble making decisions. All these factors make it dangerous to operate a motor vehicle.<\/p>\n

How Long Does Being Drunk Last?<\/h2>\n

Alcohol metabolizes<\/span> or burns off at about\u00a0one average drink per hour<\/a>. This rate is pretty standard regardless of your weight. So the more you drink, the longer you\u2019ll need to wait. You\u2019ll be unable to drive for as long as it takes for your BAC<\/span> levels<\/span> to drop below the legal limit<\/span> again.<\/p>\n

Does the Alcohol <\/span>Metabolism<\/span> Rate<\/span> Differ?<\/h2>\n

In general, people\u2019s bodies don\u2019t process alcohol at significantly different rates. While certain medical conditions can make it harder to process alcohol, other factors like body weight<\/span> and gender don\u2019t speed it up.<\/p>\n

What differs is how a person\u2019s <\/span>BAC<\/span> rises<\/span> while drinking. A smaller woman will typically have her BAC<\/span> increase more quickly and with less alcohol than a larger man. For a man, it may take five or more drinks in an hour to reach a BAC<\/span> of 0.08%, whereas it may only take two or three drinks for a woman.<\/p>\n

While you can control the amount of alcohol<\/span> you consume, you cannot control how fast it passes out of your system. No amount of coffee, food, or water will \u201csober you up\u201d quickly.<\/p>\n

Factors That Affect Alcohol Absorption<\/h2>\n

Most experts agree on several factors that affect a person’s absorption rate. Here are some factors to consider:<\/p>\n
