How Long Do I Have to File a Personal Injury Claim in Colorado?

After an injury, deadlines are probably the last thing on your mind. You are dealing with treatment, missed work, and an insurance adjuster who keeps calling. But Colorado law puts a hard limit on how long you have to file a personal injury claim, and once that window closes, your right to compensation closes with it.

The deadline is not the same for every case. Getting it wrong is one of the few mistakes in an injury case that cannot be fixed later.

What Is the Statute of Limitations for a Personal Injury Claim in Colorado?

Colorado sets two main deadlines for injury cases:

• Two years for most personal injury claims, under C.R.S. § 13-80-102
• Three years for claims arising out of the use or operation of a motor vehicle, under C.R.S. § 13-80-101(1)(n)

The two-year rule is the default. It covers negligence claims broadly, including slip and fall cases, premises liability, dog bites, and most other injuries that do not involve a vehicle.

The three-year rule is the exception that swallows a large share of injury cases, because so many serious injuries happen in traffic.

Why Do Car Accident Claims Get Three Years Instead of Two?

The two-year statute contains a carve-out. It applies to tort actions generally, except any tort action arising out of the use or operation of a motor vehicle, which is routed to the three-year statute instead.

Colorado courts have read that language broadly. In Gonzales v. City & County of Denver, the court applied the three-year deadline to an injury arising out of the plaintiff’s own operation of a motorcycle, declining to limit the rule to injuries caused by the other driver’s use of a vehicle.

Practical takeaway: if a vehicle was involved in how you got hurt, the longer deadline may apply. That includes drivers, passengers, motorcyclists, bicyclists, and pedestrians. It is still a question worth confirming rather than assuming.

What Are the Deadlines for Other Types of Injury Claims?

Several categories follow their own rules:

• Motor vehicle accidents: 3 years from the crash
• General negligence, premises liability, slip and fall, dog bites: 2 years
• Wrongful death: generally 2 years from the date of death, not the date of the injury
• Medical malpractice: 2 years, with a separate three-year outer limit
• Product liability: 2 years

Some claims carry shorter deadlines than the two-year default, so no one should assume two years is a safe floor.

The medical malpractice rule deserves a note. Beyond the two-year limit, Colorado applies a statute of repose that generally bars a claim three years after the malpractice occurred, even if you had not discovered the injury yet. There are exceptions, including a special rule for children injured before age six.

What If Your Claim Is Against a City, County, or the State?

This is where good claims die. If a public entity or public employee caused your injury, a much shorter clock applies before you ever get to the lawsuit deadline.

Under the Colorado Governmental Immunity Act, you must file a written notice of claim within 182 days of discovering your injury. The Colorado State Office of Risk Management confirms that requirement, set out in C.R.S. § 24-10-109.

A few things to know:

• Miss the 182-day notice and your claim can be barred entirely, no matter how strong it is
• The notice has to contain specific information and go to the correct entity
• After filing notice, you generally cannot sue until the entity denies the claim or 90 days pass, whichever comes first

This affects more cases than people expect: a crash with a government vehicle, a fall caused by a dangerous condition in a public building, an injury on a poorly maintained public road, or an incident at a public hospital. If a government body might be involved, the clock is measured in months, not years.

When Does the Clock Actually Start Running?

For most injury claims, the deadline runs from the date you were hurt. Wrongful death typically runs from the date of death.

Colorado also recognizes a discovery rule for situations where the injury or its cause was not obvious right away. In those cases, the clock can start when you knew, or reasonably should have known, about both the injury and its cause. That matters for harms that surface slowly, such as a delayed diagnosis or an injury that seemed minor at first.

The discovery rule is helpful, but it is not a reason to wait. Courts look at when you reasonably should have known, not simply when you chose to act.

Does the Deadline Change If the Injured Person Is a Minor?

Yes. When the injured person is a child, Colorado tolls the limitations period, meaning the clock generally pauses until they turn 18. A young person can retain the right to bring a claim into adulthood.

Two cautions. Claims against public entities still involve notice requirements that should be handled promptly, and waiting years to build a case means evidence and witnesses may be long gone. Tolling protects the legal right, not the quality of the proof.

What Happens If You Miss the Filing Deadline?

The claim is barred. A court will dismiss it, and the value of the case effectively drops to zero regardless of how badly you were hurt or how clearly the other side was at fault.

Insurers know these dates as well as any lawyer does. A claim that has been slow-walked toward the deadline gives an adjuster very little reason to negotiate seriously. Filing before the deadline preserves both your legal rights and your leverage.

Why Waiting Hurts Your Claim Long Before the Deadline

Even with two or three years available, delay quietly weakens a case:

• Surveillance video is overwritten, often within weeks
• Vehicles get repaired or scrapped before anyone inspects them
• Witnesses move and memories fade
• Gaps in treatment give insurers room to argue you were not really hurt
• Scene conditions change, so the hazard that caused the fall is gone

Most of the evidence that decides a case is gathered early, which is why the practical deadline is usually much sooner than the legal one.
