Colorado Truck Accident Lawyer Guide: Laws, Deadlines and Rights

Colorado's mountain highways turn a truck crash into a different kind of risk. Steep grades, winter storms, chain requirements and long descents make Interstate 70 the state's most dangerous corridor for commercial vehicle crashes, according to the Colorado State Patrol. This guide explains the laws that matter most after a truck crash in Colorado, including the recent increase in damage caps, the evidence to protect and how to choose a Colorado truck accident lawyer. We do not recommend or rank any individual firm.

Colorado truck accident laws at a glance

• Filing deadline: three years for injury or property damage arising from the use of a motor vehicle under C.R.S. § 13-80-101(1)(n). The general injury deadline is two years, but motor vehicle crashes are treated separately. Wrongful death deadlines depend on the facts, so confirm yours with an attorney.
• Fault rule: modified comparative fault under C.R.S. § 13-21-111. You are barred if you are 50% or more at fault.
• Liability among defendants: pro rata (several) liability under C.R.S. § 13-21-111.5. Each defendant pays its share, and a defendant can name a "nonparty at fault" to reduce its own share.
• Non-economic damages cap: $1.5 million for claims that accrued on or after January 1, 2025, adjusted for inflation starting in 2028. Crashes before 2025 fall under the earlier, lower caps.
• Wrongful death cap: $2.125 million for non-economic damages, with no cap if the death resulted from a felonious killing as defined by statute.
• Economic damages: medical bills and lost income are not subject to the non-economic cap.
• Insurance system: at-fault. Minimum liability limits for ordinary vehicles are $25,000 per person, $50,000 per accident and $15,000 for property damage. Insurers must include medical payments coverage unless you reject it.

Colorado's new damage caps

House Bill 24-1472 raised Colorado's long-standing caps on non-economic damages, such as pain and suffering, loss of enjoyment of life and emotional distress. Under C.R.S. § 13-21-102.5, the cap for most injury claims that accrued on or after January 1, 2025 is $1.5 million, and the wrongful death cap is $2.125 million under C.R.S. § 13-21-203. These figures will be adjusted for inflation beginning in 2028. The date of the crash controls, so a 2024 crash is governed by the previous, lower cap. Economic damages, such as medical expenses and lost earnings, are not subject to the cap.

The 50% bar: why fault arguments are so important

If a jury finds you 49% responsible, you can still recover 51% of your damages. At 50%, you recover nothing. The Colorado State Patrol has reported that commercial drivers were at fault in about 60% of non-fatal commercial vehicle crashes, while other drivers were at fault in about two-thirds of fatal ones, which shows how often fault is contested. Insurers know where the line is and look for arguments about speed, lane changes, braking or blind spots. Photos, video, witness statements and the truck's electronic data matter.

Truck crashes in Colorado: what the data shows

The Colorado Department of Transportation reported 684 traffic deaths statewide in 2024, a 5% decrease from 2023. The Colorado State Patrol recorded 1,270 crashes involving commercial vehicles between January and June 2024 and 1,188 in the same period of 2025, and reported 52 fatal crashes involving a commercial vehicle in 2023. I-70 has the largest number of these crashes, with the mountain corridor the main focus, especially around Floyd Hill, the Eisenhower-Johnson Tunnel grade, Vail Pass and Glenwood Canyon. The Patrol's Motor Carrier unit conducts around 40,000 commercial inspections a year.

Nationally, NHTSA counted 5,340 deaths in large-truck crashes in 2024, and about 70% of those killed were in other vehicles.

Mountain driving rules that can affect fault

• Chain law. Commercial vehicles over 16,001 pounds must carry chains on designated mountain routes, and must use them when required during winter conditions. A driver who ignores it can be negligent.
• Runaway truck ramps and brake checks. Brake failures and overheated brakes on long descents are common causes of severe crashes.
• Speed for conditions. A truck must drive at a speed safe for ice, snow, curves and traffic, even when under the posted limit.
• Hours of service. Fatigue on long mountain runs is a recurring issue. Federal hours-of-service rules limit driving time.

Who may be responsible for a Colorado truck crash

• The truck driver, for speeding, distraction, fatigue, improper lane use or driving too fast for conditions.
• The motor carrier, for negligent hiring, training, dispatch pressure or poor maintenance, including brakes and tires.
• A cargo loader or shipper, if freight was overloaded or unsecured.
• A repair shop or parts maker, if equipment failed.
• A public entity, in some cases involving road design or maintenance, subject to the 182-day notice rule and statutory damage limits.

Insurance in a Colorado truck crash

Colorado's minimum limits for ordinary vehicles are far below the cost of a serious truck injury. Under federal rules, interstate carriers hauling general freight must carry at least $750,000 in liability coverage, with higher minimums for some hazardous cargo. Many carriers carry more. Your own uninsured and underinsured motorist coverage and medical payments coverage may also apply.

Evidence that matters in a Colorado truck case

• The crash report from the investigating agency, often the Colorado State Patrol, a county sheriff or city police
• Photos and video of the scene, the truck, its markings, the USDOT number, road surface and weather
• Whether the truck had required chains or traction equipment
• Driver logs and electronic logging data. Carriers generally keep logs for only six months.
• Dash camera footage, engine data and maintenance records
• Medical records and bills from the first day

You can look up the carrier's inspection and crash history in the FMCSA SAFER system. Ask a lawyer about sending a written preservation request to the carrier quickly.

What compensation may include

• Medical expenses, past and future
• Lost income and reduced earning capacity
• Pain and suffering and loss of enjoyment of life, subject to the cap
• Property damage
• In a fatal crash, funeral costs and wrongful death damages for eligible family members
• In some cases, exemplary (punitive) damages, which are limited by statute

No one can promise a result. The outcome depends on your injuries, the evidence, the insurance available and your share of fault.

Steps to take after a truck crash in Colorado

1. Call 911 and get medical care, even if you feel fine.
2. Photograph the scene, the truck and its USDOT number, and note the weather and road conditions.
3. Do not say you were at fault, and do not guess about speed or distance. Under the 50% bar, every word can be used.
4. Make sure a police report is filed and get the report number.
5. If a public entity may be involved, speak with a lawyer immediately because of the 182-day notice.
6. Do not give a recorded statement to the trucking company's insurer without advice.

Choosing a Colorado truck accident lawyer

Confirm the lawyer is licensed in Colorado through the Colorado Supreme Court's attorney registration, ask about commercial trucking experience and mountain-corridor cases, and get the fee agreement in writing. Many injury lawyers work on contingency, so there is no fee unless you recover, but percentages and case costs vary. Read our guide on attorney fees and see our other state guides.
