While an expired registration/plate may be a somewhat minor offense which you could fix by renewing your registration (and paying any fines due) driving without insurance and with a suspended driver's license are both serious offenses and will come with harsh penalties in Colorado.
It is against the law in Colorado to drive your vehicle without insurance. If you are caught driving without insurance there are severe penalties. It is a class 1 misdemeanor traffic offense
A first offense for driving without insurance comes with a $500 minimum fine, license suspension until you can show proof to the Division of Motor Vehicles that you are insured and 4 points being placed onto your CO motor vehicle record (MVR). A second is a minimum $1000 fine and a license suspension of 4 months. A third violation comes with penalties which can include a minimum fine of $1000, community service, and an 8 month license suspension (per Colorado Statute 42-4-1409 and 1410).

A suspended license is discussed under Colorado Statute 42-2-127.7 which gives the state the authority to suspend a driver's license of an uninsured motorist.
CO Statute 42-2-138 is titled driving under restraint and penalty. Paragraph 1 subsection (a) notes that any person who drives a motor vehicle or off-highway vehicle upon any highway of this state with knowledge that the person's license or privilege to drive, either as a resident or a nonresident, is under restraint for any reason other than conviction of DUI, DUI per se, DWAI, habitual user, or UDD is guilty of a misdemeanor and, upon conviction thereof, shall be punished by imprisonment in the county jail for not less than five days nor more than six months, and, in the discretion of the court, a fine of not less than fifty dollars nor more than five hundred dollars may be imposed.
