What Is a High Blood Alcohol Content (BAC) for a DUI?

You are here: DUI > High BAC

Did you know that 32 people in the United States are killed every day in crashes involving an alcohol-impaired driver?

This is equivalent to one death every 45 minutes on average.

Think about that for a minute.

Driving under the influence (DUI) is a serious offense that can lead to severe consequences. In order to combat this, states like Nevada implemented laws and other measures to reduce DUI-related accidents.

A key factor in determining whether an individual has committed DUI is their blood alcohol content (BAC). This article will discuss what a high BAC level is and its legal implications, as well as provide information on different levels for various groups, such as minors and commercial drivers.

Definition of Blood Alcohol Content (BAC)

Blood Alcohol Content (BAC) is defined as the amount of alcohol in a person’s blood expressed as a percentage. It is expressed as a percentage and measured in grams of ethyl alcohol per 100 milliliters of blood. For example, if your BAC is 0.04%, that means you have 0.04g/100mL of ethanol-based alcohol present in your bloodstream.

From an enforcement standpoint, BAC is typically measured using specialized equipment like a breathalyzer, or sometimes in other ways such as blood draws.

Why Understanding BAC Is Important

From a legal perspective, BAC levels are used to determine whether a person is under the influence. While it’s good to know the limit, it’s better if you know the reason behind it.

Simply put—the higher the BAC, the more alcohol is present in a person’s blood and the greater their impairment. The general rule of thumb is that your body can generally metabolize one standard drink per hour; however, this can vary greatly depending on various individual factors.

If you ingest more alcohol than your body can process, the excess will be stored in your blood and tissues until it is metabolized by the liver.

That’s why alcohol affects people differently. It’s the reason why your friend seems to stumble and fall after drinking two bottles of beer, while you can stay on your feet after finishing the same amount.

Examples to Illustrate How BAC Is Calculated

As mentioned above, alcohol affects everybody differently. However, there are general guidelines to help determine BAC levels for various groups.

The “one standard drink” mentioned above is defined as containing about 14 grams of pure alcohol. This is found in:

• 12 fl oz of beer (about 5 percent alcohol by volume)
• 5 fl oz of wine (about 12 percent alcohol by volume)
• 1.5 fl oz of distilled spirits/liquor (about 40 percent alcohol by volume)

A Sunday afternoon BBQ party where you consume 5 cans of beer in 2 hours can easily put you over the legal limit. A large glass of wine can hold 8-10 ounces (or 2 servings); a Solo cup holds 15-16 ounces (3 servings).

If you don’t regulate or keep count of your drinks (or count them incorrectly), you can easily put yourself over the legal limit.

Legal BAC Limits In Nevada

Nevada’s legal BAC limit for most motorists is 0.08%.

This means that if a law enforcement officer detects a person with a BAC of 0.08% or higher, they are considered to be legally intoxicated. And if found operating a motor vehicle, they can be charged with DUI.

In addition to this, Nevada has stricter limits for certain groups.

For example, drivers under the age of 21 have a 0.02% BAC limit and commercial drivers have a 0.04% limit.

Different BAC limits exist for different groups due to safety considerations. For example, minors have a lower legal BAC level than adults because their bodies are less capable of breaking down alcohol.

Commercial drivers also have a lower legal BAC limit since they operate heavier and more dangerous vehicles that require more skill and alertness when driving.

Blood Alcohol Concentration Levels and General Effects on Individuals

According to the Cleveland Clinic, the following are the approximate blood alcohol concentration levels and their effects on individuals:

• 0.02-0.03 – A slight intensification in mood but few obvious effects
• 0.05-0.06 – Exaggeration of emotions and behaviors, feelings of warmth and euphoria, impaired judgment, a decrease in reaction and fine-motor control
• 0.07-0.09 – Physical imbalance, noticeable speech impairment, impaired motor coordination, impaired hearing and vision, increased confidence, feelings of depression or euphoria
• 0.11-0.12 – Greater difficulties with coordination and balance, impairment of judgment and mental faculties
• 0.14-0.15 – Significant impairment of physical and mental control, complete lack of motor skills, slurred speech, blurry vision
• 0.20 – Complete loss of motor control, mental confusion, inability to walk or stand
• 0.30 – Severe intoxication, possible loss of consciousness

As you can see, even at lower BAC levels and still considered legal, motor skills (which is where driving comes in) can become significantly impaired.

This is why it’s important to understand your own individual limits, and that you should always drink responsibly. Police officers are trained to notice symptoms of alcohol-impaired driving. A vehicle constantly weaving in and out of lanes at 11 PM at night gives the officer probable cause to pull you over and administer a BAC test.
