3.1 Colorado Auto Insurance Requirements

Key Takeaways

  • Colorado mandates minimum auto liability limits of 25/50/15: $25,000 per person and $50,000 per accident bodily injury, plus $15,000 property damage
  • Colorado is a tort (at-fault) state using modified comparative negligence under C.R.S. 13-21-111 with a 50% bar
  • Insurers must OFFER uninsured/underinsured motorist (UM/UIM) coverage; the insured may reject it only in writing
  • Colorado abolished mandatory no-fault PIP in 2003; medical payments (MedPay) is the optional first-party medical coverage today
  • Driving uninsured is a class 1 misdemeanor traffic offense with fines, points, and possible license suspension; SR-22 may be required after

Mandatory Liability Coverage (25/50/15)

Under the Colorado Motor Vehicle Financial Responsibility Act, every owner of a registered motor vehicle must carry a complying liability policy. The statutory minimum bodily injury (BI) and property damage (PD) limits, unchanged for 2026, are 25/50/15.

CoverageStatutory MinimumWhat it pays
BI per person$25,000Injury to one other person
BI per accident$50,000Total injury to all others in one crash
Property damage$15,000Damage to others' property/vehicles

Exam trap: The split limit applies per accident. If two claimants are each injured $30,000, a 25/50 policy pays at most $25,000 to each (subject to the $50,000 cap), leaving the insured personally exposed for the rest.

Proof of Financial Responsibility

Drivers must show proof at registration and upon a law-enforcement request. Acceptable proof includes a paper card or electronic proof displayed on a phone — Colorado statute expressly authorizes electronic verification. After certain offenses (uninsured driving, DUI, at-fault crashes without insurance), the driver must file an SR-22, a certificate filed by the insurer confirming continuous coverage, typically for three years.

Colorado's At-Fault / Tort System

Colorado is a tort (at-fault) state: the negligent driver (through their liability insurer) pays the injured party. Fault is allocated under C.R.S. 13-21-111, modified comparative negligence with a 50% bar.

  • A claimant 0%–49% at fault recovers, but the award is reduced by their own fault percentage.
  • A claimant 50% or more at fault recovers nothing.
Your fault %Recovery on $100,000 of damages
0%$100,000 (full)
25%$75,000
49%$51,000
50%$0 — barred
70%$0 — barred

Worked example: A jury finds damages of $80,000 and assigns the claimant 40% fault. Recovery = $80,000 x (1 − 0.40) = $48,000. If fault were 50%, recovery would be $0. Contrast this with a pure comparative state, where a 90%-at-fault plaintiff still recovers 10%.

Because Colorado is a tort state, the injured party's own collision coverage is not the primary source of recovery; the at-fault driver's liability policy is. This is why adequate liability limits — and UM/UIM to backstop the other driver's inadequate limits — matter so much when advising Colorado clients. Producers should routinely recommend limits well above the 25/50/15 floor, because medical inflation makes $25,000 per person inadequate for a serious injury, exposing the insured's personal assets above the policy limit.

First-Party Coverages: PIP History and MedPay

Colorado operated a no-fault PIP system until July 1, 2003, when the legislature let the no-fault act expire and returned to a tort system. PIP is no longer mandatory and is rarely sold today. The exam may test the historical fact and the current replacement: Medical Payments (MedPay) coverage.

FeatureMedPay
Mandatory?No — optional first-party coverage
Fault required?No — pays regardless of fault
PaysReasonable medical/funeral costs for insured and passengers
Wage loss?No (unlike old PIP)
Typical limits$5,000 increments commonly offered

Agents should explain MedPay coordinates with health insurance and fills gaps for deductibles and passengers who lack their own coverage.

Uninsured / Underinsured Motorist (UM/UIM)

Colorado insurers must offer UM/UIM in an amount equal to the policy's BI liability limits. The insured may reject or reduce it only by a signed written rejection; without one, UM/UIM defaults to the BI limit.

ElementRule
Must offer?Yes, equal to BI limits
Reject/reduce?Only in writing, signed
UMPays when the at-fault driver has no insurance (or hit-and-run)
UIMPays when the at-fault driver's limits are insufficient
UIM offsetColorado uses excess (add-on) UIM — UIM stacks on top of the tortfeasor's limits rather than being offset

Colorado's excess-UIM rule (often called the Jordan result) means a claimant can collect the at-fault driver's full limit and then their own UIM up to its limit, instead of subtracting one from the other.

Penalties for Driving Uninsured

Driving without the required coverage is a class 1 misdemeanor traffic offense: a minimum $500 fine for a first offense (with higher minimums and possible jail on repeats), four license points, and license suspension until proof of insurance and reinstatement are filed. These create real client risk an agent should stress when a buyer considers going bare.

Optional Physical-Damage and Add-On Coverages

Beyond the mandated liability and offered UM/UIM, Colorado drivers commonly buy several optional coverages a producer must be able to explain:

CoverageWhat it doesFault relevant?
CollisionRepairs the insured's own vehicle after a crashNo
Comprehensive (OTC)Pays for theft, hail, fire, animal strikes, glassNo
Rental reimbursementDaily rental cost while the car is repairedNo
Towing/roadsideTow and labor chargesNo
Loan/lease gapDifference between the loan balance and ACV after a total lossNo

Colorado is hail-prone, so comprehensive is heavily marketed; many carriers offer separate or reduced glass deductibles because windshield damage is so common on Front Range highways. A lender that finances or leases the vehicle will require collision and comprehensive as a condition of the loan, even though the state does not.
