What happens when you get a DUI for the first time in Colorado? 

If your blood alcohol content (BAC) is .08% or higher, you will be charged with a DUI. You can be charged with a DUI in Colorado if you were driving under the influence of alcohol, drugs, or a combination of both. The penalties for a DUI Colorado first offense are similar to a first-time marijuana DUI in Colorado, which are both classified as misdemeanors. 

If you’re facing a first-time DUI conviction, you’re facing potential fees, jail time, reputational consequences, and losing your license.  

You must file for a DMV hearing within seven days of your DUI charge to save your driver’s license. Otherwise, the Colorado DMV will suspend your license automatically. The right DUI attorney or DWAI lawyer will help you file for that hearing on time and defend you against the potential license suspension. 

What is the penalty for a DUI in Colorado? 

The penalties for a DUI are based on how high the driver’s blood alcohol content (BAC) was at the time they were pulled over and if the driver has any prior DUI convictions –– whether in or outside of the state of Colorado. 

If this is your first DUI Colorado first offense, your penalties will include:

Jail*5 days jail1 year jail
Community Service48 hours96 hours
Probation0 years2 years

*With a first-time offense, jail time is often waived as part of a suspended sentence. However, you will face a mandatory minimum jail sentence of at least ten days if you were charged with DUI and the result of a breath test or blood test shows that you had a blood alcohol content (BAC) of 0.20 or greater.

In addition to the penalties above, your driver’s license will be revoked for up to nine months. You may also be required to take a minimum 12-hour alcohol education course.

How to get your license reinstated

If you are eligible to have your license reinstated early, you must complete a one-month suspension with an Ignition Interlock Device (IID) installed in every vehicle you own for four months. After the four months, your driving privileges will be completely restored if you meet the following requirements:

  • You drive with an IID installed in your vehicle
  • Your alcohol level was below 0.15% 
  • Your BAC level was never at 0.25% or above

If you think that any of these penalties seem “not too bad,” think again. Even a DUI Colorado first offense puts your driving privileges and reputation at risk. If convicted, these consequences won’t simply go away, and the punishments only get worse. If you are charged with a 2nd DUI in Colorado, or worse, a Felony DUI in Colorado, the penalties will be MUCH harsher. That’s why it’s important to hire an expert DUI attorney like Mark Thiessen to help you fight against a first offense charge and avoid these penalties.
