Semi-auto gun ban nixed

Colorado law (2-4-401(6)) defines a minor as a person who has not attained the age of 21, except as otherwise provided in the express language of another statute. The age of majority is the age when young people are considered adults for most matters. Colorado, as many other states, has determined the age of majority to be 18 years of age or older. Individuals are treated as adults at the age of 18, with some exceptions, such as drinking alcoholic beverages (12-47-901), renting cars, and purchasing a hotel room. When an individual reaches the age of majority his or her parents are no longer liable for their child's actions. Some acts young people who have reached the age of majority may be involved in are:

entering into any legal binding contract (13-22-101(a))
managing estate (13-22-101(b))
to sue or be sued to the full extent (13-22-101(c))
making decisions regarding his or her own body (13-22-101(d))
voting in elections (Const. US., amendment XXVI)
arbitrating a claim (13-22-202)
consenting to medical treatment (13-22-102)
joining the military without guardian permission

Even though the age of majority allows young people greater rights, many young people at age 18 still live at home and are thus subject to parents rules while at home.
