What Colorado's Minimum Auto Insurance Covers (and What It Doesn't)

Colorado's minimum auto insurance is a legal starting point, not a complete list of the coverage a household might need. Understanding who each coverage pays, which losses it excludes and how its limits work makes comparing policies easier. Start with the required liability limits, then review your own vehicle, medical expenses and exposure to drivers who carry too little insurance.

The legal minimum: 25/50/15

Colorado law requires liability coverage of at least 25/50/15. The Colorado Division of Insurance (DOI) states the same limits. The numbers refer to separate payment limits, not three amounts you can freely combine.

The bodily injury limit for all people does not remove the separate limit for any one person. Property damage has its own limit. Knowing that distinction helps when you compare a quote with higher limits or read the declarations page of your current policy.

What liability pays for

Liability coverage pays others when you are at fault: their covered injuries and their damaged property. That can include another person's vehicle or other property involved in the accident. As DOI explains, liability does not pay to fix your own car or treat your own injuries. Those needs call for a separate coverage discussion, even if your liability policy meets the law.

What the minimum leaves out

Your own car: Collision covers crash damage subject to policy terms. Comprehensive, sometimes called “other than collision,” addresses losses such as theft, fire, vandalism and hail. Neither is required by Colorado law, although a lender or lease may require both, according to DOI. Review each vehicle on the policy rather than assuming every car has the same protection.

C.R.S. 10-4-621 requires insurers to offer collision coverage with $100 and $250 deductibles. An offer does not mean collision is automatically part of a liability-only policy. Ask what you have selected, what the deductible is and whether that selection meets your financing agreement.Actual rates vary by driver, home and policy.

Costs above your limits: If damages exceed the available limits, you could be personally responsible for the rest. For example, if covered property damage exceeds the $15,000 minimum limit, the amount above that limit may remain your responsibility. Actual liability and payment depend on the circumstances and policy terms.Actual rates vary by driver, home and policy.

Uninsured and underinsured motorist (UM/UIM) coverage

UM/UIM is optional, but DOI says it is included unless you reject it in writing. It pays your bodily injury damages when a not-at-fault accident involves an uninsured, hit-and-run or underinsured driver, subject to the policy. This is different from liability coverage, which addresses damage you cause to others.

For context, an estimated 19.7% of Colorado motorists were uninsured in 2023, ninth highest among states, according to the Insurance Research Council figures reported by the Insurance Information Institute and its state table archive. DOI cites an estimated 15–20%. These are estimates, not a prediction about a particular driver or trip.

We strongly recommend keeping UM/UIM and discussing an appropriate limit with your agent. Ask how it applies to household members and passengers rather than assuming it mirrors every other coverage. DOI also describes optional uninsured motorist property damage for people without collision. That is a separate question from bodily injury UM/UIM; ask about eligibility and terms before relying on it to repair your car.

Medical payments (MedPay)

Colorado includes $5,000 in MedPay unless you reject it in writing or in the same way you applied. It pays reasonable medical expenses for you and your passengers regardless of fault, and it pays before health insurance. It does not replace health insurance or turn liability coverage into coverage for your own injuries.Actual rates vary by driver, home and policy.

When reviewing MedPay, ask who is covered, how bills are submitted and how the coverage coordinates with your health plan. Keep a copy of any rejection and check that the declarations page reflects what you intended to purchase. If your household or health coverage changes, revisit that choice with your agent.

Choosing limits above the minimum

Cassondra recommends liability limits of at least 100/300/100 for most drivers. The increase from minimum limits is often just $10 to $20 a month. Actual rates vary by driver, vehicle and policy. Ask for a comparison using the same vehicles, drivers and other coverages so you can see what changes.Actual rates vary by driver, home and policy.

Discuss the assets and income you want to protect, household drivers, the vehicle's value and loan, and any umbrella eligibility requirements. Higher limits are not a promise that every possible loss will be paid. The useful question is which combination of limits, deductibles and coverages fits your circumstances and budget.

What affects your premium

A lower quote may reflect less coverage rather than a better price for the same protection. Compare liability limits, UM/UIM, MedPay, collision and comprehensive line by line. Then compare deductibles and confirm every household driver and vehicle is listed correctly. If you are considering a change, ask the agent to explain both what you gain and what you give up before deciding.

DOI identifies several rating factors. A useful quote review checks these details for accuracy instead of comparing the final price alone:

• Your address, vehicles and household drivers.
• How vehicles are used and their annual mileage.
• Your credit-based insurance score.
• Violations and at-fault accidents.
• General rate increases, which can affect renewal even when your personal circumstances have not changed.

Driving in Arvada and the west metro

I-70, US-6 and Wadsworth commuting, mountain weekends and hail all give west-metro households reasons to review more than liability minimums. Start with our auto insurance overview, talk with our Arvada agency, or see how we serve Wheat Ridge drivers. Our Colorado hail guide explains why comprehensive matters for storm damage. Bring your declarations page to a review so the conversation starts with what you actually have.
