BAC & Impairment—How Much Can You Drink?
Speak with a Birmingham DUI Lawyer
Typically, if a police officer pulls someone over for suspected drunk driving,
the officer will determine that the driver is too intoxicated to drive
by measuring their blood-alcohol percentage. The current legal limit is.
08% for drivers over 21 years old, which means that any person found with
a percentage above this is lawfully determined to be drunk, and thus too
impaired to drive.
Law enforcement uses the BAC percentage scale as a standardized way to
identify drunk drivers. One of the ways to defend a DUI charge is by challenging
your BAC results. Tidwell Law Group, LLC can help you do that.

Alcohol's Effects & BAC
Alcohol does impede many of the body's functions. As the levels of
alcohol rise in the system, it begins affecting many cognitive and motor
functions, such as coordination and the ability to process information.
At the same time, every person's body processes alcohol at different
rates, depending on their weight, age, and gender. Other factors can include
how much alcohol was consumed, if any medications or additional substances
were taken, and the rate that the alcohol was being consumed.
Other factors that can affect your BAC include:
- How much the person has had to eat or drink
- How strong the alcohol was
- Any medications or additional substances that were taken
- The rate that the person was consuming the alcohol
- How much alcohol a person has consumed
When a police officer pulls over a driver, he or she might be asked to
submit to a chemical test to measure their BAC. There are two ways to
do this. One is the breath test, which measures the amount of alcohol
on the breath. This does not mean that this is equal to the amount of
alcohol in your blood; it is merely an estimate.
Blood tests, while not as speedy as breath tests, can be more accurate
in their measurements; however, the amount of time between the stop and
the time that you actually take the blood test can actually throw off
the measurement. Both methods present room for error, which can be used
as an advantage for our Birmingham DUI attorneys to form in your case.
