Drinking and driving is a dangerous and illegal combination that can have severe consequences for yourself and others on the road. These consequences may include heavy fines, a loss of license, and in the worst-case scenario, severe injury or death. To stay safe on the road, it’s important to know when you’re too drunk to drive. So, what BAC level is considered drunk? Let’s take a look at the surprising truth!
What is BAC?
BAC stands for “blood alcohol concentration,” which is the amount of alcohol present in a person’s bloodstream. This measurement is typically expressed as a percentage. For example, a BAC of 0.10% means that there is one part alcohol for every 1,000 parts blood in the person’s body.
How is BAC measured?
BAC can be measured through a variety of methods, including breathalyzers and blood tests. Breathalyzers are the most common method used by law enforcement to determine if someone is driving under the influence (DUI). Blood tests are typically more accurate, but they are not as convenient as breathalyzers.
What factors affect BAC?
Several factors can affect a person’s BAC, including:
- Body weight: Heavier people can generally consume more alcohol before reaching a high BAC level compared to lighter people.
- Gender: Women typically have a higher BAC level than men after consuming the same amount of alcohol.
- Food intake: Eating food before drinking can slow down alcohol absorption into the bloodstream.
- Alcohol tolerance: People who consume alcohol regularly may develop a higher tolerance, and it may take more alcohol to reach the same BAC level.
- Type of alcohol: Different types of alcohol can have different effects on BAC levels.
What BAC Level is Considered Drunk?
According to the National Highway Traffic Safety Administration (NHTSA), a BAC level of 0.08% or higher is considered legally drunk for drivers in the United States. However, this does not mean that a BAC level below 0.08% is safe for driving. In fact, even a small amount of alcohol can impair a person’s ability to drive safely.
What are the Effects of Various BAC Levels?
As BAC levels rise, the effects of alcohol become more apparent. Here’s a breakdown of the effects of various BAC levels:
| BAC Level | Effects |
|---|---|
| 0.02-0.03% | Slight euphoria and loss of inhibitions. |
| 0.04-0.06% | Feeling of warmth and relaxation, impaired judgment and reasoning, decreased coordination and concentration. |
| 0.07-0.09% | Impaired reaction time and reduced coordination, difficulty steering, difficulty tracking moving objects, and reduced ability to sense danger. |
| 0.10-0.12% | Significant impairment in coordination, reaction time, and judgment, reduced ability to control the vehicle, and difficulty maintaining lane position. |
| 0.15-0.19% | Poor balance, disorientation, distorted vision and hearing, impaired speech and hearing, and difficulty standing or walking. |
| 0.20-0.25% | Severe motor impairment, loss of consciousness, and vomiting. |
| 0.30-0.39% | Severe respiratory depression, increased risk of choking on vomit, and decreased heart rate. |
| Above 0.40% | Possible death from alcohol poisoning. |
How Long does Alcohol Stay in Your System?
It’s important to note that alcohol can stay in your system for several hours after your last drink. The amount of time alcohol stays in your system depends on a variety of factors, including:
- The amount of alcohol consumed
- The person’s BAC level
- The person’s weight and body fat percentage
- The type of alcohol consumed
- The person’s metabolic rate
On average, it takes about two hours for a single drink to be metabolized and eliminated from the body. However, this can vary depending on the factors listed above.
