Blood alcohol content (BAC), also called blood alcohol concentration, is a measurement of the percentage of alcohol in a person’s bloodstream. The higher a person’s BAC is, the more intoxicated and impaired he or she is. It is illegal to drive while impaired by alcohol or another substance. If you’re pulled over with a BAC of 0.08% or higher, then you will face DUI charges, and you’ll need to hire a criminal defense attorney in Denver, CO. It’s also possible to be charged with aggravated DUI. This charge applies if you have a BAC of 0.17% or higher. As your criminal defense attorney can advise you, a conviction of aggravated DUI will result in enhanced legal penalties.
Colorado’s DUI laws cover special circumstances. It’s a zero-tolerance state, which means that drivers under the legal drinking age can be charged for having a BAC as low as 0.02%. Another exception to the standard BAC limit applies to commercial drivers. If you hold a CDL and a police officer determines that your BAC is 0.04% or higher, you can be charged with an “excess BAC DUI.”
