Rules and Regulations

Virtually all state government agencies issue rules and regulations of some kind. Most rules and regulations exist at the direction of the state legislature in order to regulate certain business and personal activities. Rules and regulations exist because it’s easier to update them, eliminate them, or alter them administratively than it is to pass new legislation each year as conditions change.

The process of reviewing and changing rules and regulations is a public one. The rules and regulations issued by the Colorado Department of Public Safety are shown here so that you may know about the process and can comment on how they could affect you or your business. Your comments will be taken into consideration during the rulemaking process, and you are always welcome to attend any meetings associated with the rulemaking process.  If you have questions concerning CDPS rules, please cont(act CDPS Rules Administrator, Bobbie Mooney at
