Additional Information about DUI penalties
The precise level of alcohol in your blood matters. Colorado DUI law and Colorado Motor vehicle law provide different penalties for different blood alcohol levels. There are important “cutoff limits” at the BAC levels of .05, .08, .17, and .20.
Even if it is your first DUI arrest, a blood alcohol content (BAC) of .08 or above triggers a Colorado DMV requirement that you install Interlock on your car for a period of 9 months.
If you are under the age of 21 and you are convicted of either DUI or DWAI you lose your driver’s license for a one year period. You also face additional penalties greater than an over-21 whose circumstances are otherwise identical.
If you are arrested and facing charges for a drinking and driving offense and you have a prior conviction for either a DUI or DWAI, no matter how old, you are facing mandatory jail time.
If you are a CU Student, the University will initiate campus disciplinary proceedings against you, even if your DUI did not happen on campus. CU has a “three strikes” policy for students with alcohol offenses. If you have had alcohol-related tickets in the past, you face more serious University penalties.
If you are not a United States citizen, a conviction for any DUI-related offense can have serious immigration consequences.
