Is there a statute of Limitations?

The "statute of limitations" is the time the prosecutor has to file charges - so it sounds like charges were filed, you plead guilty to something and didn't do everything you were supposed to. So it is not a 'statute of limitations' problem. There are two issues in Colorado - one whether there is a warrant outstanding for your arrest for not complying with the sentence (it may have been removed due to age of the case) and (2) if Colorado has put a 'hold' on your drivers license for failing to fully resolve the DUI case.  If Colorado has put a hold on your license, the only way to have it released, so you could get a valid license in another state, would be to check with the Colorado DMV and see what they need you to do in order to release the hold. It could invovle just paying money, or it could require that you prove completion of an alcohol program, maybe have an Interlock device for two years, etc. You can contact Colorado DMV or check your CO DMV driving record online if you like, or hire a lawyer to do that and advise you of what you need to do. I'd be happy to help if you like.
