Colorado DUI Laws
Your first (and hopefully last) DUI offense in Colorado can cost upwards of $10,000 in fines, court costs, legal fees, probation supervision fees, ignition interlock device (IID) rental, and other fees. But other potential costs of a DUI -- such as life-altering injuries or death -- are not so easy to quantify. While it's quite common to have a couple of drinks before getting behind the wheel, all it takes is one drink too many to get arrested, or worse. Getting yourself up to speed on the DUI laws enforced by Colorado not only will help you avoid committing the offense, but also can help you plan your next steps if you are arrested.

Ignition Interlock Devices (IID) and Restricted Licenses in Colorado
If you have been convicted of a DUI or have refused to submit to a BAC test after being stopped for suspicion of impaired driving, you may be required to have an IID installed on your vehicle. IID's require the driver to submit a breath sample, which the device then analyzes for traces of alcohol, before the engine will be allowed to start. In some instances, you may be eligible for financial aid to help pay for IID rental.
