The Legal Limit
- DUI
- In Colorado you are considered "under the influence" with a blood or breath alcohol content of .08 or greater.
- You can still be charged with DUI even if your test result comes back below .08.
- You can and will be charged with a DUI if you refuse to submit to a chemical test while showing signs or indicia of impairment or being under the influence
- DWAI
- Colorado is a no tolerance state. You may also be arrested and charged for DWAI if you have a blood or breath alcohol content between .05 and .079
- You can still be charged with DWAI even if your test result comes back below .05.
- DUID
- There is no per se limit for DUID. The state must prove that you operated a motor vehicle while under the influence or impaired to the slightest degree.
- You can and will be charged with a DUID if you refuse to submit to a chemical test while showing signs or indicia of impairment or being under the influence of drugs.
The Legal Limit for Minors
- UDD
- It is illegal for any person under the age of twenty-one to operate a motor vehicle with a blood or breath content of .02% or greater. A BAC between .02% and .05% will result in the person being charged with UDD (underage drinking and driving).
- Minors will be prosecuted the same as adults for BACs above .05%.
** Blood alcohol level is expressed in grams of alcohol per 100 milliliters of blood or grams of alcohol per 210 liters of breath.
