Why UM/UIM Matters in Colorado
Colorado requires auto carriers to offer uninsured/underinsured motorist coverage. You may accept limits up to your bodily-injury liability limits or reject in writing. The statute also makes clear that UM/UIM is in addition to liability coverage and that the amount available may not be reduced by setoffs from other coverage (e.g., MedPay, health insurance). You have to reject UM/UIM in writing, so if your insruance company failed to have you sign a rejection form, you may have UM/UIM that you didn;t know you had.
In plain English: UM/UIM is designed to fill the gap when the at-fault driver can’t fully compensate you.
UM vs. UIM: How the Coverage Actually Pays
Uninsured Motorist (UM) applies when the at-fault driver has no insurance or can’t be found.
Underinsured Motorist (UIM) applies when the at-fault driver’s insurance limits are too low for your losses.
- What gets paid: Colorado’s UM/UIM law says this coverage pays the difference between your proven damages and what the at-fault driver’s policy pays, up to your UM/UIM policy limit—without reducing your benefits by other available coverages
- Common UIM scenario: The at-fault carrier “tenders” its policy limit (for example, $25,000). If your total damages are higher, a UIM claim seeks the shortfall (subject to your UIM limit). UIM is added on top of the at fault carrier’s coverage. As an example if your injuries are $100,000 and the at fault party only has $25,000 of coverage, your UMI will pay the additional $75,000.
Quick tip: Bring your full auto policy declarations to the consult so we can evaluate your UM/UIM limits and any notice/consent-to-settle requirements in your contract.
Hit-and-Run & “Phantom Vehicle” Scenarios
If the at-fault driver can’t be located for service despite reasonable efforts, Colorado law allows a court to deem that driver “uninsured” for purposes of triggering UM benefits—subject to several conditions and proof requirements (e.g., police report that doesn’t identify an insurer). That means UM coverage may still apply even when the other driver disappears
Practical takeaway: Report hit-and-run crashes promptly, gather witness and camera information, and preserve every scrap of evidence (see checklist below).
UM/UIM even covers you if you are walking or on a bike.
UM/UIM covers you if you are injured by a vehicle. I know you weren’t in your car, but UM/UIM is so powerful that it will cover you if you are walking, on a bike, riding a skateboard…. the key is if a car injures you.
Evidence that Moves UM/UIM Claims
Insurance companies pay attention to proof. The more organized your file, the more leverage you have.
- Medical proof: ER/urgent-care records, imaging, treatment notes, prognosis, and future-care opinions.
- Work & income: pay stubs, W-2s/1099s, employer letter, or vocational analyses for lost earning capacity.
- Crash documentation: police report number, photos/video, vehicle damage patterns, scene diagram, 911/CAD logs, and any surveillance or dashcam footage.
- Daily impact: pain journal, out-of-pocket expenses, mileage to appointments.
Colorado Deadlines
Most motor-vehicle injury claims in Colorado carry a three-year statute of limitations from the date the claim accrues. Other personal-injury claims are often two years, but the motor-vehicle category is generally three. Policy-level notice and consent deadlines can be much shorter, so early action is critical.
Act now: If you’re approaching any anniversary of the crash—or you’ve received forms from your insurer about UM/UIM—call 303-762-9500 so we can protect your claim and timeline.
Our Process
- Coverage map: We identify every insurance source—at-fault BI, your UM/UIM, any MedPay—and confirm policy conditions.
- Proof & valuation: We build a damages package (medical, wage, future care, pain/suffering) that reflects real-world impact.
- Negotiation: We press the at-fault carrier to tender limits where appropriate—then pursue UIM to cover the shortfall.
- Arbitration/litigation if needed: If your own insurer disputes value, we’re prepared to arbitrate or sue under the contract.
Results matter: In one recent auto case, our client recovered $100,000 from the at-fault driver and an additional $300,000 through UM/UIM coverage.
What to Do Right Now
- Get medical care and follow doctor recommendations. Gaps in treatment hurt claims.
- Notify your insurer that you were hit by an uninsured/underinsured driver (or a hit-and-run). Do not give recorded statements to the other driver’s carrier.
- Save evidence: Photos, receipts, damaged items, and all communications.
- Bring your policy documents (declarations and any endorsements) to your consult.

FAQs: Colorado UM/UIM
Do I have a case if the other driver fled?
Possibly. If the driver can’t be located for service after reasonable efforts—and other statutory conditions are met—a court may deem them uninsured for UM purposes. Evidence and prompt reporting are key.
Does UM/UIM get reduced by my MedPay or health insurance?
Colorado’s statute says UM/UIM “shall not be reduced by a setoff from any other coverage,” including legal liability insurance, MedPay, health insurance, or other UM/UIM.
How long do I have to bring a UM/UIM claim?
Motor-vehicle bodily-injury claims generally have a three-year limitations period, but policy notice/consent requirements can be much shorter—speak with counsel right away.
What’s the difference between UM and UIM again?
UM applies when the at-fault driver has no insurance or can’t be found; UIM applies when their limits are too low to cover your losses. Colorado law treats UIM as paying the difference between your damages and the at-fault policy payment, up to your limit.
Does rideshare (Uber/Lyft) change anything?
Yes—Colorado requires certain UM/UIM protections during a prearranged ride and bars TNCs from rejecting this coverage for those periods. If your crash involved a rideshare, ask us about the layered coverage.
