Car Accident Laws in Colorado: Fault, Insurance & Deadlines

Colorado is an at-fault (tort) state, not a no-fault state. The driver who caused the crash — through their liability insurance — is responsible for the other person's injuries and damage; there is no mandatory personal injury protection (PIP) coverage to fall back on first. If you're hurt, you generally have three years from the date of the crash to file a personal injury lawsuit (C.R.S. § 13-80-101(1)(n)) — longer than the two-year window many people assume applies, but still a hard deadline. If a government vehicle or employee was involved, that window shrinks dramatically to 182 days to send written notice. Confirm every deadline and dollar figure below against current Colorado law before you rely on it — insurance minimums and damage caps are adjusted periodically.

1. Colorado's Fault System: At-Fault, Not No-Fault

Colorado experimented with a no-fault insurance system for years, but the state legislature repealed it effective July 1, 2003. Since then, Colorado has run on a traditional tort-based, at-fault system. In practice that means:

• The at-fault driver's liability insurance pays for the other driver's medical bills, lost wages, and property damage — not your own insurer, unless you're the one who caused the crash.
• You are legally allowed to file a claim directly against the at-fault driver's insurance company, negotiate a settlement, or file a lawsuit if a fair settlement isn't offered.
• There is no state-mandated personal injury protection (PIP) coverage that automatically pays your medical bills regardless of fault, the way there is in true no-fault states.

This matters for how you approach a claim: in Colorado, establishing who caused the crash is central to who pays, which is why the shared-fault rule discussed below (section 4) can directly reduce — or eliminate — what you recover.

2. Minimum Auto Insurance Required in Colorado

Under Colorado's financial responsibility law, drivers must carry at least the following liability limits, commonly written as 25/50/15:

• $25,000 bodily injury liability per person
• $50,000 bodily injury liability per accident (total, if more than one person is hurt)
• $15,000 property damage liability per accident

A few important gaps to understand:

• PIP / medical payments coverage is not required. Because Colorado repealed its no-fault system in 2003, there is no statewide mandate that drivers carry personal injury protection. Optional medical payments ("MedPay") coverage is sold by many insurers, but you have to add it yourself — confirm current availability and terms with your carrier or the Colorado Division of Insurance.
• Uninsured/underinsured motorist (UM/UIM) coverage must be offered — but can be declined. By law, insurers must offer you UM/UIM coverage equal to your bodily-injury liability limits before issuing or renewing your policy. You can reject that coverage, but only in writing. If you don't actively reject it, it's part of your policy — and it matters, since a meaningful share of Colorado drivers carry only the state minimum or no insurance at all.

These minimums and offer requirements can change. Verify current figures with the Colorado Division of Insurance (Department of Regulatory Agencies) before assuming they still apply.

3. Statute of Limitations: Your Deadline to Sue

For crashes in Colorado, the deadlines are shorter and less forgiving than many people expect:

• Personal injury (bodily injury) claims: three years from the date of the crash, under C.R.S. § 13-80-101(1)(n), which specifically covers tort actions arising from the operation of a motor vehicle. This is longer than Colorado's general two-year personal injury statute (C.R.S. § 13-80-102) because the legislature carved out a special three-year window for motor vehicle accidents.
• Property damage claims: also generally three years from the date of the crash under the same motor-vehicle-specific statute.
• Wrongful death claims: generally two years from the date of death under C.R.S. § 13-80-102, with a longer window available in certain cases involving vehicular homicide where the at-fault driver fled the scene. Confirm the applicable period for your situation.
• Minors: the clock is generally paused (tolled) until the injured minor turns 18, after which the standard filing period begins to run.

Missing your deadline typically means losing the right to sue entirely, regardless of how clear fault is or how serious your injuries are. Because exceptions and discovery-rule nuances exist, don't count backward from memory — confirm your specific deadline with the Colorado courts or an attorney well before it approaches.

4. Shared Fault: Colorado's Modified Comparative Negligence Rule

Colorado uses modified comparative negligence with a 50% bar, codified at C.R.S. § 13-21-111:

• If you are found less than 50% at fault (0–49%), you can still recover damages — but your award is reduced by your percentage of fault. For example, if you're 20% at fault and your damages total $100,000, you'd recover $80,000.
• If you are found 50% or more at fault, Colorado law bars you from recovering anything.

This is often called the "50% bar rule," and it's a meaningful distinction from states that cut off recovery at 51% or that allow recovery even if you're mostly at fault (pure comparative negligence). In Colorado, the fault-percentage finding — often disputed by insurers — can be the difference between a full recovery and nothing.

5. Crash Reporting: When You Must Notify Police or Authorities

Under C.R.S. § 42-4-1606, a driver involved in a crash must give immediate notice to the nearest local police agency or the Colorado State Patrol when the crash involves any of the following:

• Injury to any person
• Death of any person
• Property damage (the reporting officer isn't required to complete a full investigation or written report if damage is reasonably estimated at $1,000 or less and no one is hurt — unless a driver requests a report or can't show proof of insurance)

Failing to report a reportable crash can lead to misdemeanor charges. If you're unsure whether your crash crosses the reporting threshold, err on the side of notifying law enforcement at the scene, and confirm any additional reporting steps with the Colorado State Patrol or your local police department.

6. Damage Caps and Claims Against a Government Vehicle

Two limits are easy to miss and can significantly affect a claim:

• Noneconomic damage caps. Colorado caps "noneconomic" damages (pain and suffering, and similar losses, as distinct from medical bills and lost wages) in most personal injury cases under C.R.S. § 13-21-102.5. The cap amount is periodically adjusted and has different figures for standard injury cases versus medical malpractice cases, so don't rely on any single number without checking the current, inflation-adjusted figure. Economic damages — your actual medical bills, lost wages, and property loss — are not subject to this cap.
• Claims against a government vehicle or employee. If you were hit by a city, county, state, school district, or other public entity's vehicle, the Colorado Governmental Immunity Act (CGIA) applies instead of the standard timeline. You must send a written notice of claim within 182 days of discovering your injury (C.R.S. § 24-10-109) — far shorter than the three-year deadline for a private at-fault driver. Courts treat this deadline strictly, and missing it can bar your claim entirely even if you later file within the normal three-year window. If any government vehicle, employee, or agency was involved — a police cruiser, snowplow, transit bus, or municipal truck — treat 182 days as your real deadline and act immediately.

What to Do After a Crash in Colorado

1. Check for injuries and call 911 if anyone is hurt, or if the crash may exceed the $1,000 damage/no-report threshold — get police to the scene when in doubt.
2. Move to safety if the vehicles are drivable and it's safe to do so, but don't leave the scene before fulfilling your legal duty to report and exchange information.
3. Exchange information with the other driver(s): name, contact information, insurance company and policy number, license plate, and driver's license number.
4. Document the scene with photos of vehicle damage, license plates, road conditions, traffic signals or signs, and any visible injuries.
5. Get the police report number or badge information if an officer responds, and request a copy of the report afterward through the Colorado DMV or the responding agency.
6. Seek medical care promptly, even if you feel fine — some injuries surface hours or days later, and prompt documentation supports any future claim.
7. Notify your own insurer of the crash, even though you'll likely be filing against the at-fault driver's policy — most policies require prompt notice regardless of fault.
8. Identify if a government vehicle was involved. If so, note that you may have only 182 days to send formal written notice under the Colorado Governmental Immunity Act — don't wait.
9. Keep records of medical bills, missed work, repair estimates, and correspondence with insurers as your claim develops.
10. Confirm your deadlines — the three-year injury/property-damage window, the 182-day government-claim window if it applies, or any shorter window an insurance policy itself may impose for notice — before they pass.
