It depends. How important is not going to jail? How important is it to minimize the impact of a DUI on your driving privileges?
There is an old saying in the legal community -- "He who represents himself has a fool for a client."
If you just want to give up and take whatever consequences a district attorney or judge is ready to hand out, by all means, represent yourself. Many defendants do this but they rarely take advantage of all of their rights and often make mistakes in the complicated field of Criminal Defense.
If you would rather take advantage of the rights that the United States Constitution and the laws of Colorado afford you, then you should hire an aggressive Criminal Defense and DUI attorney.
This field of law requires a great deal of specialized knowledge. There are very specific needles to find in a muddled haystack. You need a knowledgeable Colorado Criminal Defense and DUI attorney to sift through the materials obtained from the police and the district attorney and prepare the proper defense against the state.
