What counts as a catastrophic injury under Colorado law?

Colorado law does not set a single fixed definition, but the term is generally used for injuries that permanently change how you live: traumatic brain injuries, spinal cord injuries, severe burns, the loss of a limb, and other harm that requires ongoing medical care or support. What matters most for your claim is not the label, but the long-term impact of the injury on your health, your ability to work, and your daily life.

How long do I have to file a catastrophic injury claim in Colorado?

It depends on how the injury happened. If it arose from a car, truck, or motorcycle crash, you generally have three years from the date of the accident. For most other negligence-based injuries, such as a fall on unsafe property, the deadline is generally two years. If a government entity may be responsible, you generally must file written notice within 182 days, well before either deadline would otherwise run. Because the correct deadline depends on the facts of your case, it is worth confirming it early.

Is there a cap on what I can recover for a catastrophic injury?

Colorado does not cap economic damages, such as medical bills, future care, and lost income, which are often the largest part of a catastrophic injury claim. Non-economic damages, such as pain and suffering, are capped for most claims filed on or after January 1, 2025. Because economic damages are uncapped, thoroughly documenting the true, lifetime cost of the injury is one of the most important parts of the case.

Why do catastrophic injury claims usually need outside experts?

The cost of a serious injury rarely ends when treatment does. Ongoing care, home modifications, assistive equipment, and lost future earning capacity can extend for decades. Medical and vocational experts help translate a diagnosis into a realistic projection of what your care and lost income will actually cost over your lifetime, which is often the difference between a settlement that covers your future needs and one that falls short.

What if I was partially at fault for the accident that caused my injury?

You can still recover damages as long as you were less than 50 percent at fault, with your recovery reduced by your own percentage of fault. If you are found 50 percent or more at fault, you cannot recover from the other party. Given how much is often at stake in a catastrophic injury claim, how fault is investigated and argued matters a great deal.

What if my loved one can no longer make decisions for themselves?

Some catastrophic injuries affect a person's cognitive function or ability to communicate, which can require a family member to seek a legal guardianship or conservatorship before a claim can move forward on their behalf. This adds a layer most personal injury claims do not have, and it is worth raising early so the right legal steps happen in the right order.

How long do I have to file a truck accident lawsuit in Colorado?

Claims arising from the use or operation of a motor vehicle, including semi-truck and tractor-trailer crashes, generally must be filed within three years. If a government entity may share fault, written notice is required within 182 days, a far shorter window. The practical deadline is often sooner than the legal one, because critical carrier records can be destroyed on routine schedules within months of the crash.

Who do I sue after a semi-truck accident, the driver or the company?

Often both, and frequently others. The motor carrier is generally responsible for its driver's on-the-job negligence, and it can also be directly liable for its own failures in hiring, training, scheduling, or maintenance. Shippers, cargo loaders, maintenance contractors, and brokers can share responsibility depending on the facts. Identifying every liable party matters because it determines the insurance available to pay the claim.

Are truck drivers held to different standards than other drivers?

Yes. Commercial drivers must hold a CDL, follow federal hours-of-service limits, submit to drug and alcohol testing, and operate under a stricter impairment threshold of 0.04 percent blood alcohol, half the limit for other drivers. Their employers must inspect and maintain vehicles under federal rules. Violations of these standards are often central to proving a truck accident claim.

The trucking company's insurer already offered me a settlement. Should I take it?

Be cautious with any early offer. Quick settlements are typically made before the full extent of your injuries and future costs is known, and accepting one ends your claim permanently, even if your condition worsens. Before signing anything, it is worth having an attorney review the offer against the actual long-term cost of your injuries. Elkus & Sisson offers a free consultation for exactly that purpose.

What is my truck accident claim worth?

There is no fixed formula, but truck claims are often worth more than car crash claims for two reasons: the injuries tend to be more severe, and there is usually more insurance available because federal law requires carriers to hold higher coverage. Your claim generally reflects your economic losses, which Colorado does not cap, plus noneconomic losses like pain and suffering, which are capped for most injury claims filed on or after January 1, 2025. Shared fault reduces recovery, which is why the insurer's version of events should never go unchallenged. Documenting the full long-term cost is what protects the value of the claim.

What evidence should be preserved after an 18-wheeler crash?

The most important records belong to the carrier: electronic logging device data, engine control module data, driver qualification files, drug and alcohol test results, inspection and maintenance records, dispatch records, and any dashcam footage. On your side, keep photos from the scene, witness contact information, medical records, and all correspondence from insurers. A preservation letter from an attorney puts the carrier on legal notice not to destroy its records.

Truck Driver Fatigue Accident Lawyer in Colorado

A fatigued truck driver reacts slower, drifts out of lanes, and misses hazards a rested driver would catch. Unlike alcohol, there is no roadside breath test for exhaustion, which is exactly why fatigue crashes often get written off as ordinary driver error unless someone investigates the driver’s hours, logs, and the pressure they were under to keep driving.

Elkus & Sisson, P.C. represents people injured by drowsy and overworked truck drivers across Colorado. We investigate driver logs, ELD data, and carrier scheduling practices to determine whether fatigue played a role in your crash, as Colorado truck accident attorneys.

Why Truck Driver Fatigue Is So Dangerous

A large truck takes longer to stop and offers a driver less margin for a delayed reaction than a passenger car does. Fatigue slows reaction time, narrows attention, and in severe cases can produce brief involuntary lapses in awareness known as microsleep, all while the driver is operating a vehicle that FMCSA describes as often 20 to 30 times heavier than a passenger vehicle, with a fully loaded tractor-trailer weighing up to 80,000 pounds^[6].

Common Signs of a Fatigued Driver

Investigators look for a combination of signs, since no single one is conclusive on its own:

Drifting between lanes or onto the shoulder without an apparent cause
A delayed or missing braking response before impact
A crash occurring in the early morning or late night hours
The driver admitting to feeling tired or falling asleep
Witness accounts describing erratic or inattentive driving before the crash

Hours-of-Service Rules and Driver Logs

Federal rules under 49 C.F.R. § 395.3^[1] limit how long a driver may drive and remain on duty, helping reduce fatigue-related safety risks. A driver’s hours-of-service record and ELD data can show whether they were operating near or beyond those limits, or had a pattern of short or interrupted rest, in the period leading up to the crash. Our hours-of-service violations page covers these federal limits and how violations are investigated in more detail.

Carrier Pressure and Scheduling

Fatigue is not always just a personal choice. Tight delivery windows, dispatch pressure, and detention time—the often uncompensated time a driver spends waiting to load or unload—can all push a driver toward the road when they should be resting. A 2018 U.S. DOT Office of Inspector General analysis^[3] found that, while noting significant limitations in available industrywide detention data, a 15-minute increase in average dwell time at a facility was associated with a 6.2 percent increase in expected average crash rate, consistent with the idea that lost time creates pressure to make it up on the road.

When a carrier’s own scheduling, dispatch practices, or pay structure created that pressure, the carrier’s conduct becomes part of the investigation, not just the driver’s.

Investigating a Fatigue-Related Truck Crash

Building a fatigue case usually means gathering the driver’s hours-of-service records and ELD data, dispatch and detention records, the police report, and any available black box or engine data, then looking at how they fit together. Our evidence after a truck accident page covers how this evidence is preserved and obtained in more detail.

A documented pattern consistent with fatigue can support a negligence claim against the driver and, where the carrier’s own practices contributed, against the carrier as well, under Colorado’s comparative negligence law, C.R.S. § 13-21-111^[4]. Colorado generally gives you three years from the date of the crash to file a claim, C.R.S. § 13-80-101(1)(n)^[5], the same deadline that applies to other truck accident claims.

Frequently Asked Questions

What are common signs a truck driver was fatigued at the time of a crash?

No single sign proves fatigue on its own, but a pattern of them can be telling: drifting out of a lane without an obvious cause, a delayed or absent braking response, a crash in the early morning or late night hours when the body’s circadian rhythm favors sleep, a driver who admits feeling tired or falling asleep, or a driver who appears disoriented at the scene. Investigating these signs alongside the driver’s logs and ELD data is what turns a suspicion into supportable evidence.

How is hours-of-service data used to prove driver fatigue?

A driver’s hours-of-service record shows how much they had driven, how long they had been on duty, and when they last had a qualifying break before the crash. A driver operating beyond federal limits, or whose records show a pattern of short or irregular rest, may present indicators worth investigating for fatigue. HOS records do not by themselves prove the driver’s level of fatigue at the time of the crash. Our hours-of-service violations page covers how these records are obtained and what they can show in more detail.

Can I hold the trucking company responsible for a fatigued driver, not just the driver?

Often, yes. If a carrier’s scheduling practices, dispatch pressure, or tolerance of hours-of-service violations contributed to the driver being on the road while fatigued, that can support a claim against the carrier directly, separate from the driver’s own negligence. Patterns across multiple trips or drivers are usually more persuasive than a single incident.

What is detention time and how does it relate to driver fatigue?

Detention time is the time a driver spends waiting to load or unload at a shipper or receiver, often uncompensated or under-compensated. Extended detention can pressure a driver to make up lost time by driving longer or skipping rest, particularly under pay structures based on mileage rather than hours. Federal researchers have examined detention time specifically because of its connection to fatigue-related safety risk.

How quickly does evidence of driver fatigue need to be preserved?

It depends on the type of evidence. Driver logs and their supporting documents are federally required to be kept for at least six months, but the truck’s engine or black box data has no equivalent federal retention requirement and may be overwritten, altered, or lost through continued use of the vehicle. Physical evidence at the scene can also degrade or change over time, which is why early investigation matters.

Talk to a Colorado Truck Accident Attorney About Driver Fatigue

Some electronic vehicle data and physical evidence may be overwritten, altered, repaired, or lost through continued use of the truck or changes at the crash scene, and federal HOS rules do not provide those records the same six-month retention requirement that applies to driver duty-status records, 49 C.F.R. § 395.8(k)^[2].
