Auto insurance in Colorado: what’s required, and what isn’t
Colorado requires 25/50/15 liability coverage, and quietly puts uninsured motorist coverage on your policy unless you have signed something declining it. The state verifies coverage continuously against a database rather than at renewal. What makes Colorado distinctive is less the requirement than the loss environment behind the price: this is a hail state with a fast-growing population and a low property damage floor, and all three show up on a quote.

|---|---|
| Bodily injury, per accident | $50,000 |
| Property damage, per accident | $15,000 |
Colorado also requires
- Uninsured/underinsured motorist — included unless you reject it in writing
- Colorado does not compel UM/UIM coverage, but it does something close: the coverage is included in your policy automatically and comes off only if you reject it in writing. If you have never signed a rejection, you almost certainly have it. Check before assuming you do not.
These are floors, not recommendations. Colorado sets the minimum a driver may legally carry. It does not assess whether that amount would cover a claim you caused. Anything above your limits is your personal exposure.
How Colorado enforces it
Colorado runs the Motorist Insurance Identification Database, which cross-references vehicle registrations against carrier policy data to identify uninsured vehicles without a traffic stop. Coverage is verified continuously rather than at renewal.
How rates are set in Colorado
Colorado is an at-fault state. It has not always been — Colorado operated a no-fault system until 2003 — but today the driver responsible for a crash is responsible for the resulting injury and property damage, and their liability limits cap what the insurer pays.
The Division of Insurance, part of the Department of Regulatory Agencies, reviews carrier rate filings. Colorado is a competitive-rating state: the regulator checks that rates are not excessive, inadequate or unfairly discriminatory, but does not set a single approved price. Carriers apply their own filed models to garaging ZIP, vehicle, record and credit-based insurance score.
Two coverages are optional in Colorado but function differently from ordinary optional extras. Uninsured/underinsured motorist is on by default and requires a written rejection to remove. Medical payments coverage must be offered to you, and also requires a written rejection — it pays your own medical costs after a crash regardless of who was at fault, which is the closest thing Colorado retains to its former no-fault structure.
Credit-based insurance scores in Colorado
Colorado permits credit-based insurance scores in rating. Colorado has seen fast population growth and correspondingly fast rate movement, and carriers have adjusted their models at different speeds — which widens the spread between quotes more than in a stable market.
What actually moves your premium here
Hail is the defining comprehensive risk
The Front Range sits in one of the most active hail corridors in North America, and Colorado regularly produces billion-dollar hail events. This lands almost entirely on comprehensive coverage, not liability. If you park outside along the I-25 corridor, comprehensive is doing real work and the deductible you choose on it matters more here than in most states.
The $15,000 property damage minimum is the weak point
Colorado sets property damage at $15,000 — well below its own bodily injury figures and below most neighbouring states. In a market where a large share of the vehicle fleet is late-model trucks and SUVs, $15,000 is exhausted easily in an ordinary at-fault collision, and the balance is personal exposure.
Mountain driving is a genuine rating input
Steep grade, winter conditions and wildlife collisions produce a claims pattern in mountain counties that differs from the Front Range. Carriers price it, and they price it inconsistently with each other, so this is one of the profiles where comparing widely pays off most.
Rate movement has been fast
Colorado has had one of the sharper multi-year run-ups in auto premium in the country, driven by growth, repair costs and catastrophe losses. In a market moving this quickly, a quote you accepted two years ago is a poor guide to what the same carrier would charge you now — in either direction.

Question 1 of 3
What’s your ZIP code?
Comparing carriers in Colorado
Price comprehensive deliberately rather than by default. In a hail state, the comprehensive deductible is one of the highest-leverage numbers on a Colorado policy, and carriers differ substantially in how they price the step between deductible tiers.
Check whether the quote you are looking at includes UM/UIM and medical payments, because a quote that has silently stripped both will look cheaper than a comparable one that has not. In Colorado this is a common source of apparent price differences that are not real.
One habit matters more than any single carrier choice: re-check every year or two, and again after anything that changes your risk profile — a move across town, a new vehicle, a driver added or removed, or a violation ageing off your record. Carriers re-weight their rating factors continuously, so the one that priced you best three years ago is often not the one that prices you best today.
If you need an SR-22 in Colorado
Colorado requires an SR-22 filing after certain suspensions, including driving without insurance and DUI-related convictions. Your insurer files it with the state and must notify the state if the policy lapses. Not every carrier writes SR-22 policies, so if you need one, filing capability is a screening question before price. Confirm the period that applies to your case with the Colorado Division of Motor Vehicles, as it runs from reinstatement rather than from the offence.
Colorado auto insurance FAQ
- What is the minimum car insurance required in Colorado?
- Liability coverage of at least $25,000 for bodily injury per person, $50,000 for bodily injury per accident, and $15,000 for property damage — written as 25/50/15.
- Is uninsured motorist coverage required in Colorado?
- Not strictly required, but it is included on your policy automatically and can only be removed if you reject it in writing. If you never signed a rejection, you most likely have it.
- Is Colorado a no-fault state?
- No, not any more. Colorado operated under a no-fault system until 2003 and is now an at-fault state. Medical payments coverage, which pays your own medical costs regardless of fault, is the closest remaining echo of the old system, and carriers must offer it to you.
- Why has my Colorado car insurance gone up so much?
- Colorado has had one of the sharper multi-year premium run-ups in the country. The main drivers are population growth along the Front Range, rising vehicle repair costs, and repeated severe hail events producing large comprehensive losses. Carriers have re-rated at different speeds, which is why shopping tends to produce a wider spread here than in a stable market.
- Does hail damage come out of my liability coverage?
- No. Hail is a comprehensive claim, not a liability claim. If you carry liability only, hail damage to your own vehicle is not covered at all — which is a meaningful gap on the Front Range.
