Colorado law considers the age of majority to be 18-years-old in many cases, including for many criminal charges. At 18, a young person who is charged with a crime in Colorado may have to deal with the general courts, instead of with the juvenile courts that specialize in working with younger individuals.
At 18, a young person is no longer considered a “juvenile” for situations like fighting or other assaults, reckless driving, and many other acts. A young person can also be tried in criminal courts for offenses related to drinking, since the drinking age in Colorado – just like in every other U.S. state – is 21-years-old, not 18. These include both minor in possession of alcohol matters and driving under the influence of alcohol (DUI).
