Blood Alcohol Content: What The Results Will Mean To You, Your Future and The Court

Do you know what the term Blood Alcohol Content (BAC) means? It’s the referred to the alcohol amount that a person has in their bloodstream. BAC is used to state how much alcohol is in the blood to volume of blood that’s in the body. People who have been pulled over for suspected DUI or who have been in an accident quickly become familiar with the term.

Now, cops can measure a person’s intoxication level using a breathalyzer during the traffic stop. If the test reveals a 0.08 percent result, the person is thought of as legally drunk and charged with a DUI.

Why A Breathalyzer Result Can Be Considered Inaccurate

Keep in mind that a breathalyzer result can yield inaccurate results because of the following:

- Vomited recently
- Sores in mouth
- Injuries in mouth
- Taking certain kinds of medication
- Dental caps
- Bridgework

If you have any of these conditions, it’s important to let the officer know before the test is given to you.

Alcohol and You

Each person is affected differently by alcohol based on several factors including age, ethnicity and sex. Each one will affect how rapidly you begin to show intoxication signs. Even if a person is not legally drunk (0.08 percent), alcohol will affect coordination, judgment, decrease depth perception and affect the peripheral vision. Every one of these conditions will affect your driving abilities. The BAC is a valid way to find out how a person will act when they consume alcohol.

It’s true that certain people have built up a tolerance to alcohol to a certain point. That means they may not be as impaired as someone who has never drank alcohol before. However, the BAC is still used as a guideline to determine if someone is drunk or not.

Body weight also plays a role to the number of drinks it’ll take to make the BAC rise to an illegal level. A small person generally just needs two drinks to make that BAC rise and consider them legally drunk. Any driver under 21 years of age can be held to strict standards. They could lose their driving privileges for a time if they have a BAC level of 0.01 percent to 0.05 percent. There are many states that have no tolerance for people who drink before the age of 21.

A BAC will be determined by both a urine and blood test. Like the breathalyzer test, there can be some minor variations in the results. This variation can be used by an attorney for a DUI defense. Sometimes challenging the tests can result in the case being dismissed or a sentence reduction but most courts find the results valid. Of course, to keep your BAC from being elevated is to limit how much alcohol you drink.

Should You Use Home Model Breathalyzers

Home model breathalyzers have been created to help persons determine if they are able to drive safely after they have been drinking for a time. However, these things can result in false readings. Home model breathalyzers should never be relied upon to determine if you can drive or not, as they will not hold up in court for a DUI defense. Only medical personnel who administer a blood and/or urine test can give accurate BAC readings. The best things you can do is not drink and drive, don’t drive after you’ve been drinking or have someone sober take you home.
