After a couple of drinks at a party or out with friends, many people find themselves in moderate or semi-high BAC ranges of 0.04%–0.10%. Too high for driving, for example, is a number regulated by your state. This is 0.08% in all U.S. states except for Utah, where it’s 0.05%. But that doesn’t mean it’s safe to drive if you’re below those numbers. When it comes to driving, most U.S. states place the legal limit at 0.08% BAC (0.08 g of alcohol per deciliter of blood), but alcohol doesn’t wait for 0.08% before it affects your functioning.

It may also apply to commercial drivers such as bus and truck drivers. You can be charged with a drunk driving offense even if your BAC is not above the legal limit. However, it’s harder for a prosecutor to prove their case if your BAC was not tested or if you were below the allowable amount. It is also important to understand that tests — particularly breath tests — are unreliable and susceptible to attack by an attorney who is knowledgeable in the science of blood-alcohol analysis.
Blood alcohol level charts can help you understand the effects of drinking based on your weight and sex. The charts can also help you plan ahead if alcohol is on the menu. An experienced drunk driving defense lawyer can help you to understand your options for fighting DUI charges — even if your blood alcohol level was high. You should contact an attorney as soon as possible for help defending yourself against serious accusations. Although these percentages might seem small, tiny variations in your BAC can greatly affect your body’s systems, cognition, and how drunk you feel — whether that’s tipsy or blackout drunk.
Blood Alcohol Content Chart: Blood Alcohol Levels Explained
At moderate-to-high BAC levels, it’s also common to experience exaggerated emotions like excitement, sadness, happiness, or even rage. For most people, consuming 2 to 3 drinks in 1 hour can impair you past the legal limit for driving. However, it’s important to note that any alcohol in your system will impair your cognitive and physical functions. The following charts show how your blood alcohol levels change as you consume alcohol.
But alcohol may affect your functioning before you reach this limit. If you are above the legal limit, though, the prosecutor does not need to show any additional evidence of impairment besides showing what your BAC level was. The term “per se” means ‘the thing speaks for itself.” In a DUI per se offense, your BAC speaks for itself and is sufficient to show you were too drunk to be behind the wheel. If you drink heavily or have been worrying about your BAC often, it might be a sign that you’re struggling with alcohol abuse or dependence. While you might feel like it’s under control — or that you can manage it on your own — know that you don’t have to do it alone. BAC can range anywhere from 0.01% (slightly “feeling it”) to 0.30%+, which is dangerously high.
Does Tolerance Affect BAC?
If your BAC is above this level, you are presumed intoxicated in every state. Ria Health offers several FDA-approved medications for alcohol use disorder. When combined with counseling, this approach is proven highly effective. Quitting alcohol completely can be a challenge, but there are more ways to do it than ever before.

A Blood Alcohol Levels Conversion Chart is used to estimate a person’s blood alcohol concentration (BAC) based on the number of standard drinks they have consumed. Knowing how to accurately test your BAC can help you abide by laws and stay safe, and it’s especially important if you plan on driving when the alcohol wears off. However, calculating exactly how drunk you are can be challenging, even if you’re counting your drinks or using tools like blood alcohol content charts. When it comes to alcohol and safety, blood alcohol content (BAC) is an important metric that helps determine a person’s level of impairment.
BAC Limits Across the United States
Blood alcohol content (BAC) is a number that reflects the alcohol concentration in a person’s body, calculated by the amount of alcohol (in grams) per 100 mL of blood. As an example, a BAC test showing 0.06 would mean that 0.06% of your blood’s volume is alcohol. The results of the breathalyzer, blood or urine test will largely determine the charges brought and the possible sentences.

However, since your estimation may not be exact, it’s best to err on the side of caution and avoid drinking and driving at all. But what exactly is BAC, and what do different BAC levels feel like? Below, find a simple blood alcohol content chart, symptoms of each blood alcohol level, and how to accurately test your BAC. When you consume alcohol, your blood alcohol content level (BAC) rises.
- But alcohol may affect your functioning before you reach this limit.
- When you drive in any U.S. state, implied consent laws require you to submit to a BAC test if there is probable cause you are impaired.
- Vomiting is likely and the chance of asphyxiation on your own vomit is greatly increased.
- This “zero tolerance” level sets the legal limit much lower for specific people.
- (If you are a man, you will have difficulty achieving or maintaining an erection.) You will have trouble walking or standing and are at a greater risk of hurting yourself physically.
The BAC is measuring the amount of alcohol within a 30- to 70-minute period. When you drive in any U.S. state, implied consent laws require you to submit to a BAC test if there is probable cause you are impaired. For a more specific BAC estimate, you can use a BAC calculator that factors in your weight, sex, the number of standard-sized drinks you’ve had, and the time that’s passed since your last drink. Because most people won’t have easy access to tools like these, a general rule of thumb is to not drive if you feel buzzed or tipsy. It can also be helpful to remember that, on average, your body can process one drink per hour, but this can vary based on other factors that affect your alcohol metabolism. Safety is the number one priority when it comes to drinking alcohol, and driving is just one well-known area of risk.
The blood alcohol level chart below shows what the BAC limit is in every state — including the legal limit for DUI per se offenses as well as the zero tolerance limit. When you think of BAC, breathalyzers, drunk driving, or legal trouble might be the first things that come to mind. However, it can also be used in other situations where safety or health are important. For instance, employers might test for BAC in certain workplace settings, and nurses or doctors will check BAC when treating a person for alcohol poisoning.
What would your BAC be after 3 drinks?
Also, individual tolerance should not be overlooked; although not an issue with the “per se” offense, tolerance is very relevant to the DUI offense. Your BAC level measures the amount of alcohol in your blood, therefore traveling through your body to every organ, including your brain. In its simplest form, calculating a person’s BAC level is based on how much alcohol went into what kind of body over a period of how much time. Ultimately, consuming alcohol can pose a risk to your health and the health of others. Planning ahead for designated drivers, keeping track of your alcohol intake, and finding ways to drink less can all help make your nights out safer.
Many factors impact your blood alcohol level including your gender and your body weight. The chart below shows your likely BAC based on the number of drinks you consumed. Blood Alcohol Content (BAC) charts are used to estimate the level of alcohol in a person’s bloodstream based on factors such as weight, gender, and the number of alcoholic drinks consumed. These charts help determine a person’s level of intoxication and potential impairment.
Under implied consent laws, if you are arrested, police can mandate you have your blood alcohol content tested. Refusal to do so can result in penalties including fines, fees, and the administrative suspension of your license. The refusal to submit to testing can also be used against you in your drunk driving case. A blood alcohol level chart can help you to understand the legal limit and determine if you are likely to exceed it and thus risk blood alcohol level chart and guide being charged with DUI. The truth is that tolerance does not affect BAC, but instead makes your body and mind more resistant to the effects of alcohol, even at high BAC levels.
You may begin feeling tired because the depressant qualities of alcohol begin to take effect. (If you are a man, you will have difficulty achieving or maintaining an erection.)
