A Colorado car accident insurance claim is usually two or three claims running side by side: one against the driver who caused the crash, and one or more against your own policy. Knowing which is which explains most of what adjusters say to you.
This guide covers the at-fault system in general terms, the coverage layers that tend to matter after a Denver crash, and the habits that keep a claim clean. It is general information about how the system works, not advice about your policy. Policies differ, and the wording of yours controls.
How Colorado's At-Fault System Works
Colorado ended its no-fault auto insurance system on July 1, 2003. Since then, the basic rule is that the driver who caused a crash is responsible for the other people's losses, and that driver's liability insurance is what usually pays them. Every Colorado driver must carry liability coverage of at least $25,000 per person and $50,000 per accident for bodily injury, plus $15,000 for property damage (C.R.S. 10-4-620).
In practice, that creates two kinds of claims:
- Third-party claims. You claim against the at-fault driver's insurance. The adjuster represents their policyholder. They investigate fault, may assign you a share of it, and usually pay injury claims once, as a lump-sum settlement after treatment ends, in exchange for a release.
- First-party claims. You claim under your own policy: collision, Medical Payments, uninsured or underinsured motorist coverage. Your insurer owes you duties under the contract, and you owe it cooperation.
Fault is not all or nothing. Colorado lets an adjuster, and later a jury, split blame by percentage, and a large enough share on your side can wipe out an injury claim entirely. That rule gets its own page: Colorado comparative negligence explained.
The Coverage Layers That Usually Matter
| Coverage | Whose policy | What it generally does |
|---|---|---|
| Bodily injury liability | At-fault driver | Pays injured people for losses the policyholder caused, up to the policy limits. |
| Property damage liability | At-fault driver | Pays to repair or replace the other people's vehicles and property. |
| Medical Payments (MedPay) | Yours | Pays medical bills regardless of fault, up to a set amount. Insurers must offer at least $5,000 unless you decline in writing (C.R.S. 10-4-635). |
| Uninsured motorist (UM) | Yours | Steps in when the at-fault driver has no insurance or cannot be found, as in many hit-and-runs. |
| Underinsured motorist (UIM) | Yours | Helps when the at-fault driver's limits are too low for your losses. Must be offered; declining requires writing (C.R.S. 10-4-609). |
| Collision | Yours | Repairs your car regardless of fault, minus your deductible. Your insurer may later seek repayment from the at-fault driver's insurer. |
The one-page summary at the front of your policy lists each coverage and its limit. Many people discover MedPay or UIM coverage they did not know they had. If a coverage is missing, ask your agent whether you signed a written rejection.
Colorado's UM/UIM rules have changed over the years, including how underinsured coverage interacts with the at-fault driver's limits and what an insurer must tell you before you settle. Because those details matter and depend on dates and policy language, they are a good topic to raise with a licensed attorney. A summary is not enough.
Who Pays? A Scenario Explorer
Pick a situation to see which coverage layers usually come into play. This is a simplified illustration. Your policy wording, limits and the facts decide the real answer.
- BITheir bodily injury liabilityYour medical costs, lost wages and other injury losses, up to their limits.
- PDTheir property damage liabilityRepair or replacement of your car, rental and related costs.
- MPYour MedPayEarly medical bills, regardless of fault, up to your MedPay limit.
- UMYour uninsured motorist coverageInjury losses when there is no liability policy to claim against.
- UIMYour underinsured motorist coverageInjury losses beyond the at-fault driver's limits.
- COYour collision coverageYour car's repair, minus the deductible, without waiting on fault.
Working With Adjusters Without Hurting Your Claim
Adjusters handle many claims at once and are judged partly on how much they pay. That does not make them villains; it means their job and your interests are not the same. A few habits help:
- Keep it written. After any phone call, send a short email confirming what was said. Ask for important requests and offers in writing.
- Think before a recorded statement. You generally have no duty to give one to the other driver's insurer. If you choose to, keep answers short, factual and limited to what you know.
- Narrow the medical authorization. A blanket release can open years of unrelated records. You can ask for one limited to the crash-related care and a reasonable time period.
- Do not settle injury claims early. A settlement almost always comes with a release that ends the claim for good. Signing before you know the full extent of an injury is the classic regret.
- Track every number. Claim numbers, adjuster names, direct lines, dates. The file you keep becomes the timeline everyone else relies on.

Car Damage, Rentals and Total Losses
Property damage usually moves faster than injury claims. You can claim against the at-fault driver's property damage liability coverage, or use your own collision coverage and let your insurer pursue the other company. Using your own coverage is often quicker but costs your deductible up front, which your insurer may recover for you later.
If the car is declared a total loss, the insurer typically pays its actual cash value: what a similar car was worth just before the crash, not what you owe on the loan. Ask how the value was calculated and which comparable vehicles were used. If you believe the number is low, gather listings for similar cars in the Denver market and send them in writing. Claims for loss of use and reduced resale value after repairs exist in some situations; how they apply depends on the facts and the policy.
When a Claim Stalls or Gets Denied
Delays happen: the adjuster changes, records go missing, fault is disputed. A polite written follow-up with a specific request ("please confirm by Friday whether liability is accepted") often moves things. If it does not, there are other routes. The Colorado Division of Insurance takes consumer complaints. For first-party claims, Colorado law gives policyholders a remedy when their own insurer unreasonably delays or denies payment of covered benefits (C.R.S. 10-3-1115 and 10-3-1116). Whether that applies is a legal question for a licensed attorney.
Negotiating with an insurer does not pause the statute of limitations. A claim can be "still in discussion" on the day the deadline passes. Read the Colorado car accident statute of limitations guide and keep the date in view.
If a claim involves injuries, low limits, disputed fault or a denial, many people decide it is worth getting a lawyer's view. The guide to choosing a Denver car accident lawyer explains what to ask in a first meeting.
Questions About Colorado Car Insurance Claims
Do I have to give a recorded statement to the other driver's insurer?
In general, no. You have no contract with the other driver's insurance company. You can decline, offer to answer specific questions in writing, or speak with an attorney first. Your own policy is different: it usually requires you to cooperate with your own insurer.
What are Colorado's minimum car insurance limits?
Colorado requires liability coverage of at least $25,000 for bodily injury to one person, $50,000 for bodily injury per accident and $15,000 for property damage (C.R.S. 10-4-620). Many drivers carry more. Minimums can run out quickly when someone is seriously hurt.
What is underinsured motorist coverage in Colorado?
UIM coverage on your own policy can pay when the at-fault driver's liability limits are not enough to cover your losses. Under C.R.S. 10-4-609, insurers must offer it, and it can only be declined in writing. Check your declarations page to see what you have.
Can I file a complaint about an insurance company in Colorado?
Yes. The Colorado Division of Insurance, part of the Department of Regulatory Agencies, accepts consumer complaints about insurers. A complaint is not a substitute for legal action and does not stop any deadline from running.
