A drunk driving arrest in Colorado comes with numerous consequences. There's the possibility for jail time and also a fine. The state will likely suspend your driver's license.

Many people accused of drunk driving will eventually need to install an ignition interlock device (IID) in their vehicles to be able to drive legally. There are two different situations in which a driver arrested for drunk driving might have to install an IID in their vehicle under Colorado law.

After the state suspends your license

Losing your driving privileges can impose a significant hardship not only for you but also for your family. Drivers who have served at least part of their license suspension can apply for a restricted license.

You have to install an IID in any vehicle that you will drive during the remainder of the suspension period. How long you have to maintain the IID in your vehicle will depend on the number of previous offenses on your record or any aggravating factors present with this offense.

After refusing a chemical breath test during a traffic stop

A police officer can't physically force you to perform a breath test during a traffic stop. Still, the state can penalize you for refusing a test requested when an officer has probable cause to suspect chemical impairment.

If you refused to perform a chemical breath test, the police officer could arrest you for that refusal. Having a restricted license for two years is one of the possible penalties. Understanding when the state may mandate an IID in your vehicle can help you better respond to pending drunk driving charges and decide whether an IID is right for your needs.
