Colorado Car Accident Laws: Fault, Insurance, and Your Claim

Colorado is an at-fault (tort) state that follows modified comparative negligence with a 50% bar, meaning the at-fault driver's liability insurer pays for your injuries and property damage, and you can recover as long as you are less than 50% at fault, though your award is reduced by your percentage of fault.

Is Colorado a no-fault or at-fault state?

Colorado is an at-fault (tort) state. When you are injured in a car accident, you pursue compensation through the at-fault driver's liability insurance, not through your own personal injury protection policy. Colorado was once a no-fault state under the Colorado Auto Accident Reparations Act, but the General Assembly repealed that law effective July 1, 2003, and returned the state to a pure fault-based system. Mandatory liability insurance is now governed by C.R.S. Title 10, Article 4, Part 6.

Because Colorado imposes no no-fault threshold, there is no verbal or monetary bar you must clear before you can sue for non-economic damages like pain and suffering. Any injured party may bring a third-party liability claim against the at-fault driver for all damages (economic and non-economic alike) from the moment of the crash. Personal injury protection (PIP) is not required in Colorado. Medical Payments (Med-Pay) coverage works differently from PIP: under C.R.S. § 10-4-635(1)(a), an auto liability policy cannot be delivered or issued in Colorado unless it provides $5,000 in medical payments benefits, and C.R.S. § 10-4-635(1)(b) allows a policy without that coverage only if the named insured rejects it in writing. Med-Pay is therefore an opt-out default rather than an optional add-on, and if the insurer cannot prove you rejected it, C.R.S. § 10-4-635(1)(c) presumes your policy includes $5,000 of Med-Pay.

How fault is shared: Colorado's negligence rule

Colorado follows modified comparative negligence with a 50% bar, codified at C.R.S. § 13-21-111. Under this rule, a court assigns each party a percentage of fault for the accident. If your share of fault is 49% or less, you can recover damages from the other party, but your award is reduced by your own percentage. If you are found 50% or more at fault, however, you are completely barred from recovery.

This rule has real consequences for multi-car crashes and cases where both drivers share blame. For example, if a jury awards $100,000 but finds you 30% at fault, you receive $70,000. If the jury finds you 50% at fault, you recover nothing. Insurance adjusters routinely use comparative-fault arguments to reduce or eliminate offers, so understanding your actual percentage of responsibility matters before you accept any settlement. The 50% bar (as opposed to the 51% bar used in some other states) makes Colorado's standard slightly less forgiving for plaintiffs.

Minimum car insurance in Colorado

Colorado law requires all drivers to carry minimum liability coverage of 25/50/15 under C.R.S. § 10-4-620. That means at least $25,000 for bodily injury or death to any one person, $50,000 for bodily injury or death to all persons in any one accident, and $15,000 for property damage in any one accident. This framework sits within the Motor Vehicle Financial Responsibility law at C.R.S. Title 10, Article 4, Part 6, and Title 42, Article 7.

Uninsured and underinsured motorist (UM/UIM) coverage is not mandatory, but under C.R.S. § 10-4-609(1)(a)(I) insurers must automatically include it in the bodily-injury limits set by C.R.S. § 42-7-103(2), which are $25,000 per person and $50,000 per accident. The coverage stays on your policy unless you reject it in writing. Higher UM/UIM is a separate step: C.R.S. § 10-4-609(2) requires the insurer to offer you the right to obtain UM/UIM in an amount equal to your own bodily-injury liability limits, but that higher coverage applies only if you actually select it. The Colorado Division of Insurance (DORA) confirms that most policies carry UM/UIM unless the policyholder actively waives it. Given Colorado's large share of uninsured and underinsured drivers on its roads, keeping UM/UIM in place is a practical safeguard. Med-Pay provides first-party coverage for medical expenses regardless of fault, and under C.R.S. § 10-4-635 your policy carries $5,000 of it unless you rejected it in writing.

How long you have to file: the statute of limitations

Colorado gives car-accident victims three years to file a personal-injury or property-damage lawsuit arising from a motor-vehicle collision. This comes from C.R.S. § 13-80-101(1)(n), which expressly places all tort actions for bodily injury or property damage arising out of the use or operation of a motor vehicle in the three-year limitations category. This is notably longer than Colorado's general two-year personal-injury statute of limitations at C.R.S. § 13-80-102(1)(a), which expressly excludes motor-vehicle torts.

The clock starts running when you know, or reasonably should know, both the injury and its cause under the discovery rule at C.R.S. § 13-80-108. Waiting too long is fatal to your case: even one day past the deadline gives the defendant grounds to dismiss your lawsuit entirely. If your accident involved a government vehicle or a government employee driving on duty, shorter notice-of-claim deadlines under the Colorado Governmental Immunity Act may apply, so consult an attorney promptly in those situations. For a broader look at Colorado's civil filing deadlines, see the Colorado statute of limitations page.

What a Colorado car accident claim is worth

The value of a Colorado car accident claim depends on your actual economic losses plus non-economic damages, offset by your share of comparative fault. Economic damages include medical bills (past and future), lost wages, loss of future earning capacity, and property damage. Non-economic damages cover pain and suffering, emotional distress, loss of enjoyment of life, and inconvenience.

Colorado caps non-economic damages under C.R.S. § 13-21-102.5(3)(a)(II) at exactly $1,500,000 for any claim for relief that accrues on or after January 1, 2025, and for civil actions filed during calendar year 2025. That figure does not move until the first inflation adjustment on January 1, 2028 under C.R.S. § 13-21-102.5(3)(c)(I)(B). Claims that accrued earlier fall under the far lower limit in subsection (3)(a)(I), and wrongful-death and medical-malpractice claims are governed by their own separate caps. Economic damages have no statutory cap. In practice, the at-fault driver's minimum 25/50/15 policy often determines how much money is actually available after a serious crash. If the at-fault driver is underinsured, your own UM/UIM coverage fills the gap up to your policy limits. Colorado's 50% comparative-fault bar means any contributory negligence on your part directly reduces your net recovery.

What to do after a car accident in Colorado

The steps you take immediately after a collision can protect both your health and your legal rights. First, move to safety if possible and call 911. Colorado law requires you to report accidents resulting in injury, death, or significant property damage to law enforcement. While waiting for police, check on all parties and do not admit fault or apologize, since any statements can be used against you later.

Document the scene thoroughly. Take photos of vehicle positions, damage, skid marks, traffic controls, and any visible injuries. Collect names, contact information, insurance details, and driver's license numbers from all drivers involved, along with contact information from witnesses. If officers respond, get the report number. Seek medical attention as soon as possible, even if you feel fine initially, because symptoms of whiplash, concussion, or soft-tissue injuries often appear hours or days later. Gaps in medical care give insurers grounds to argue your injuries were not serious or were caused by something else. Before you give a recorded statement to the at-fault driver's insurer or accept any settlement offer, speak with a licensed Colorado personal-injury attorney. Initial consultations are typically free, and accepting an early offer may permanently release all future claims.

This article is general legal information, not legal advice. Car accident law varies by state and changes, and settlement values depend on the specific facts. For advice about a specific crash, consult a licensed attorney in Colorado.

Frequently Asked Questions

Is Colorado a no-fault state?

No. Colorado repealed its no-fault Auto Accident Reparations Act effective July 1, 2003. Colorado is now a tort (at-fault) state, meaning you recover from the at-fault driver's liability insurer, not through your own PIP policy. There is no serious-injury threshold you must cross to sue for pain and suffering.

Is Colorado an at-fault state for car accidents?

Yes. Colorado has been a pure at-fault (tort) state since July 1, 2003. The injured driver pursues a third-party liability claim against the driver who caused the accident. The at-fault driver's insurance company is responsible for paying bodily-injury and property-damage claims up to its policy limits.

What is the statute of limitations for a car accident in Colorado?

Three years from the date of the accident (or from when you knew or should have known of the injury) under C.R.S. § 13-80-101(1)(n). This is longer than Colorado's general two-year personal-injury deadline, which expressly excludes motor-vehicle torts. Missing the deadline bars your lawsuit entirely.

Can I still recover if I was partly at fault in Colorado?

Yes, as long as you are less than 50% at fault. Colorado follows modified comparative negligence with a 50% bar under C.R.S. § 13-21-111. Your damages are reduced proportionally by your percentage of fault. If you are found exactly 50% at fault, you recover nothing.

What are the minimum insurance requirements in Colorado?

Colorado requires minimum liability coverage of 25/50/15: $25,000 per person for bodily injury, $50,000 per accident for bodily injury, and $15,000 for property damage (C.R.S. § 10-4-620). UM/UIM coverage is automatically included at the $25,000 per person and $50,000 per accident statutory minimum limits unless you reject it in writing under C.R.S. § 10-4-609(1)(a)(I). UM/UIM matching your own higher liability limits is something the insurer must offer under C.R.S. § 10-4-609(2), but you must affirmatively purchase it.

How much is my Colorado car accident claim worth?

It depends on your economic losses (medical bills, lost wages, property damage) and non-economic losses (pain and suffering, emotional distress), reduced by your share of comparative fault. Colorado caps non-economic damages at $1,500,000 for any claim for relief accruing on or after January 1, 2025 under C.R.S. § 13-21-102.5(3)(a)(II), a figure that does not adjust for inflation until January 1, 2028. Economic damages are uncapped. Use the Colorado car accident settlement calculator for an estimate.

Is PIP required in Colorado?

No. Colorado eliminated mandatory personal injury protection (PIP) when it repealed its no-fault act in 2003. Medical Payments (Med-Pay) coverage is a different matter: C.R.S. § 10-4-635 bars an insurer from issuing a Colorado auto liability policy without $5,000 in Med-Pay benefits unless the named insured rejects that coverage in writing, so most policies carry it by default. PIP itself is not required.
