Driving Under Restraint, 42-2-138: if you drive without a suspended driver's license in Colorado you can face the charge of driving under restraint. For a non-alcohol revocation this is usually handled as a fine though jail could be involved. For those revoked due a violation of Express Consent through DMV (either a refusal or having over an .08 BAC), a conviction for DUI or other similar offense the penalty for "DUR-Alc" could be a mandatory minimum 30 days in jail. It is therefore important to know the status of your driver's license. You can check the status of your Colorado Driver's License at https://mydmv.colorado.gov/_/#2
