Calculating BAC

Blood Alcohol Concentration (BAC) measures the amount of alcohol present in your bloodstream. It’s critical to understand your BAC in various situations, whether you’re considering driving after having a drink or have been charged with Driving Under the Influence (DUI). For DUI cases, law enforcement officers may conduct field sobriety tests. These tests typically include standing on one leg, walking heel-to-toe in a straight line, or tracking a light with your eyes. Failing these tests could lead an officer to suspect alcohol or drug use, prompting further testing, such as breath tests or chemical analysis of blood or urine.

What Is Blood Alcohol Concentration?

When you consume alcohol, it enters your bloodstream, raising your BAC level. Most states, including Pennsylvania, set the legal BAC limit for adults at 0.08%. Surpassing this legal limit can result in DUI charges. A BAC of 0.08% represents 0.08 grams of alcohol per 100 milliliters of blood.

For individuals under the legal drinking age, Pennsylvania enforces a zero-tolerance policy. This means that a BAC as low as 0.02% or higher is sufficient for an automatic DUI charge.

What Factors Affect BAC?

Several factors play a role in influencing your BAC. Understanding these can help you better gauge how alcohol affects you:

• Gender: Women typically have a higher BAC compared to men who drink the same quantity. This is often due to differences in body composition and size.
• Body Fat: Individuals with a higher body fat percentage tend to have a higher BAC. This is because fat tissue does not absorb alcohol as effectively as other body tissues do.
• Empty Stomach: Drinking on an empty stomach can lead to a quicker rise in BAC levels. However, eating before drinking helps slow alcohol absorption, resulting in a lower BAC.
• Body Size: Smaller or lighter individuals usually experience a higher BAC compared to larger individuals drinking the same amount of alcohol. This is due to alcohol having less volume to disperse through smaller bodies.

If you’re facing any questions or issues regarding these factors and how they relate to traffic violations, a Somerset criminal lawyer can provide expert advice tailored to your unique situation.

Determining BAC

To effectively calculate your BAC, you’ll need details about what you consumed, how much, and over what duration. Here are some general guidelines on what constitutes one standard drink:

• 5 ounces of wine (alcohol content 15–20%)
• 12 ounces of beer (alcohol content 4–4.5%)
• 1.5 ounces of liquor (alcohol content 30–50%)

For reference, a Long Island Iced Tea, which combines multiple liquors, has an approximate alcohol content of 22%.

To estimate BAC, tools such as Widmark’s Formula are often used. This formula factors in the number of drinks consumed, your weight, the alcohol content of the beverages, and how long you were drinking. The formula is as follows:

BAC = (ounces of alcohol consumed * 5.14 / weight in pounds * gender constant) – 0.015 * hours since drinking began

The gender constant is 0.66 for women and 0.73 for men.

Example:

If a 150-pound woman drinks two 12-ounce beers in two hours:

% BAC = (1.20 x 5.14 / 150 x 0.66) – 0.015 x 2

% BAC = (6.168 / 99) – 0.03

% BAC = 0.062 – 0.03

Final % BAC = 0.032, which is under the legal limit of 0.08%.

Knowing your BAC is a valuable tool, especially when facing legal implications. Should your BAC exceed the lawful limits, consult a Somerset DUI attorney for guidance and representation.

What To Do When Your BAC Is Too High

First and foremost, comply with any request for a breath or blood test. Refusing to take the test typically results in an automatic license suspension and may lead to additional charges.
