Blood Alcohol Content (BAC)
Calculate and Understand B.A.C. for Colorado DUI & DWAI related cases
When it comes to DUIs and DWAIs, your Blood Alcohol Content (BAC) level
is an important factor that comes into play. Understand what it is and
how to measure it to benefit your case in Colorado.
What Is BAC?
BAC is short for “blood alcohol content,” or “blood alcohol concentration.” It also refers to the amount of ethanol concentration in your
blood and is commonly known as your blood alcohol level.
Your blood alcohol content level measures (by a percentage in deciliters
of blood) how intoxicated you are and is used as a measure to define whether
or not you are legally under or over the limit for driving while under
the influence in your state.
Individual state laws for BAC driving limits vary, so be sure to check
your state’s driving laws to learn the legal limit applying to your
situation if you are not in Colorado.
How to Measure BAC – Blood Alcohol Content Calculators and Alcohol Charts
Two common ways to measure your blood alcohol content level is to use a
BAC calculator or alcohol chart. However, these methods can only be used
as mere points of reference for your level of intoxication. For a 100%
accurate assessment, a blood test or Breathalyzer is needed.
BAC calculators are simply a way to give you a general idea of your level
of intoxication, not a proven measure of your actual blood alcohol level,
and many other factors must be taken into consideration to assess the
amount of alcohol an individual can safely ingest.
The BAC calculator below provides a general estimate of what your blood
alcohol level will be after drinking a certain amount over a period of
time. However, we do not recommend drinking and driving under any circumstance
or while under any influence, and advise you to use a designated driver
