Is Colorado a No-Fault State for Car Accidents?

Colorado is not a no-fault state for car accidents. It’s an at-fault (or “tort”) state, which means the driver who caused the crash is financially responsible for the other party’s injuries and damage, and that driver’s liability insurance is where your claim goes. Colorado used a no-fault system until July 1, 2003, when the legislature allowed those statutes to expire and shifted to the tort model most other states use.

What At-Fault Means for Your Claim

In an at-fault system, the person who caused the collision bears the financial responsibility for the harm it did. If another driver runs a red light and hits you, you file a claim with their liability insurer for your medical bills, lost wages, vehicle damage, and pain and suffering. If that claim doesn’t produce a fair result, you can sue the driver directly.

Under the old no-fault system, each driver’s own insurance paid for their own medical expenses regardless of who caused the wreck, and you had to meet a minimum injury threshold before you could sue the at-fault driver. That threshold is gone. Today, you can pursue the other driver from the start, no matter how severe or minor your injuries.

The practical consequence is that the other driver’s insurance adjuster, not yours, is the person you’ll be dealing with on the main claim. That adjuster works for the company that has to pay you, so expect them to investigate aggressively and look for reasons to pay less. They’ll rely on the police report, any traffic citations issued at the scene, witness statements, and photos or video of the damage and roadway.

How Your Own Fault Can Reduce or Erase Your Recovery

Colorado applies a modified comparative negligence rule under C.R.S. § 13-21-111. If you were partly to blame for the crash, your compensation is reduced by your percentage of fault. If your share hits 50% or more, you recover nothing at all.¹

The math is straightforward. If a jury finds your total damages at $100,000 and assigns you 20% of the fault, you take home $80,000. At 49% fault, you receive $51,000. At 50%, you get zero.¹

That cliff is why fault disputes get sharp. Anything the other side can point to, whether you were a few miles over the limit or glanced at your phone before impact, becomes a reason to push your percentage up. One point across the line and the entire claim collapses.

What the At-Fault Driver’s Insurance Owes You

Colorado law lets you recover both economic and non-economic damages from the at-fault driver.

Economic damages are the measurable losses:

Emergency care, hospital stays, surgery, rehabilitation, medications, and future medical treatment your injuries require.
Wages lost during recovery and reduced future earning capacity if your injuries limit the work you can do.
The cost to repair or replace your vehicle and any personal property damaged in the crash.
Out-of-pocket expenses like transportation to medical appointments and childcare during recovery.

Non-economic damages cover harm that doesn’t come with a receipt: physical pain and suffering, emotional distress, loss of enjoyment of life, and loss of consortium. These are real losses, but there’s no formula for them, which is where most of the back-and-forth with the insurer happens.

Colorado caps non-economic damages. For claims accruing on or after January 1, 2025, the cap is $1.5 million. That figure holds until January 1, 2028, when it begins adjusting every two years based on the Denver-area consumer price index.² The cap applies only to non-economic damages. Economic losses like medical bills and lost income are recoverable in full, subject only to any comparative negligence reduction.

Why Your Own Policy Still Matters

Even though Colorado is at-fault, two coverages on your own policy end up doing important work after a serious crash. Colorado requires insurers to offer both and treats a missing written rejection as acceptance.

Medical Payments Coverage

Insurers must offer at least $5,000 in Medical Payments (MedPay) coverage on every auto policy. MedPay covers medical expenses for you and your passengers regardless of who caused the accident. You can decline it, but only in writing. If the insurer can’t show you rejected it, the law presumes your policy includes the $5,000 automatically.³

MedPay matters most in the first weeks after a crash, when bills arrive long before the liability claim against the other driver resolves. It keeps your treatment moving while the insurance companies work out fault.

Uninsured and Underinsured Motorist Coverage

Insurers must also offer Uninsured/Underinsured Motorist (UM/UIM) coverage in an amount matching your liability limits. Same rule as MedPay: rejection has to be in writing, and otherwise it’s part of your policy.⁴

UM/UIM is what you fall back on when the at-fault driver has no insurance or carries too little to cover what they did. Colorado’s required minimum liability limits are only $25,000 per person and $50,000 per accident for bodily injury, plus $15,000 for property damage.⁵ A single ER visit with imaging can exceed $25,000, so running into an underinsured driver after a serious wreck isn’t a remote possibility. UM/UIM is the coverage that steps in when the at-fault driver can’t make you whole.

You Have Three Years to File Suit

If you need to go to court, Colorado gives you three years from the date of the crash to file a personal injury or property damage lawsuit arising from a motor vehicle accident. The deadline sits in C.R.S. § 13-80-101(1)(n), which carves motor vehicle cases out of the state’s shorter two-year tort limit.⁶

Three years sounds like plenty of time, and it goes faster than people expect while they’re focused on getting better. Miss it and the court will dismiss the case no matter how strong the evidence. Adjusters know the deadline too, so slow-walked negotiations that stretch past the three-year mark without a lawsuit on file effectively eliminate the insurer’s exposure. If settlement talks are dragging, filing suit before the clock runs out keeps your claim alive.
