Colorado Revised Statutes Title 10. Insurance § 10-4-621. Required coverages are minimum

(1) Nothing in this part 6 shall be construed to prohibit the issuance of policies providing coverages more extensive than the minimum coverage required by section 10-4-620, nor to require the segregation of such minimum coverage from other coverages in the same policy. However, loss statistics as to bodily injury liability and property damage liability shall be kept separately for rating purposes, and such statistics shall be filed with the commissioner each year.

(2) On and after January 1, 2005, all insurers shall offer collision coverage for damage to insured motor vehicles subject to deductibles of one hundred dollars and two hundred fifty dollars. Insurers may offer such other reasonable deductibles as they deem appropriate. Collision coverage shall provide insurance without regard to fault against accidental property damage to the insured motor vehicle with another motor vehicle or motor vehicle caused by physical contact of the insured with another object or by upset of the insured motor vehicle, if the accident occurs within the United States or its territories or possessions.

(3) No insurer may surcharge, refuse to write, cancel, or nonrenew a complying policy of automobile insurance based solely on the method of compliance or level of coverage chosen, as long as the requirements are met under section 42-3-105(1)(d)(I) or (1)(f), C.R.S.
