Living in Colorado is a great privilege and comes with an endless supply
of things to do outdoors, four beautiful seasons and adventures for everyone.
However, along with the altitude comes the risk for dehydration and faster
intoxication. For locals as well as newcomers, keeping in mind your personal
consumption limit and situation is important to avoiding health issues
and legal trouble. Understanding state driving laws and how to assess
your level of intoxication is worthwhile to stay safe. To this end, a
BAC calculator can come in handy.
Keep in mind, a BAC calculator is simply a point of reference to give you
a general idea of your blood alcohol content level. It is not a replacement
for a breathalyzer or blood test, and we recommend not drinking and driving at all.
Many individual factors also play into your BAC level, so there is no one-size-fits-all
standard for determining how many drinks will bring a person past their
limit. Such factors include:
- How much you’ve eaten recently
- How hydrated you are/recent fluid intake
- Kidney function
- Drinking habits/tolerance level
- Amount of time between drinks
That said, a BAC calculator can be beneficial for your personal reference and use.
How BAC Calculators Work
To determine your overall tolerance level and total consumed alcohol, most
online BAC calculators will ask you to input your gender, the number of
drinks you’ve consumed (usually broken down by fluid oz. of beer,
wine and shots of hard liquor), the number of hours over which you consumed
them, your weight, the percent alcohol in the drinks, and perhaps your
The calculator will then apply a formula to determine your BAC level measured
by a percentage in deciliters of blood. Results will show your estimated
BAC percentage and sometimes even the amount of time in which you will
be back to sober and can legally drive (if past the legal limit).
To learn more about computing BAC estimates, take a look at the
U.S. Department of Transportation.
Colorado DUI and DWAI BAC Limits
Remember, everyone’s drinking limit is different and so are the individual
state laws for BAC driving limits. In Colorado, state intoxication limits
for driving are:
DWAI (Driving While Ability Impaired): 0.5% - 0.8%
DUI (Driving Under the Influence): 0.8% +
