Truck Accident Claims in Colorado

Key Takeaways

• A truck accident claim is a personal injury claim, but it runs on a different set of rules than a car crash claim because federal trucking regulations create duties that ordinary drivers do not have.
• More than one party is usually responsible. The driver, the motor carrier, a maintenance contractor, a cargo loader, or a parts manufacturer can each carry a share of the fault.
• Federal law requires most interstate carriers hauling general freight to carry at least $750,000 in liability coverage, roughly seven times the amount many Colorado drivers carry on a personal auto policy.
• Critical evidence in truck cases has a short shelf life. Driver logs, dispatch records, and engine data can be gone within months of the crash.
• If a government-owned truck, bus, or plow caused the injury, the deadline to give written notice is 182 days, far shorter than the three-year deadline that applies to most Colorado crash claims.

What makes a truck accident claim different from a car accident claim?

A truck accident claim differs from a car accident claim in three ways: the size of the injuries, the number of parties who can be held responsible, and the body of federal safety regulation that applies to the vehicle. Everything else about the claim, including the requirement to prove negligence, works the same way it does in any Colorado personal injury case.

The physics explain the first difference. A fully loaded tractor-trailer can weigh up to 80,000 pounds. A midsize sedan weighs roughly 3,300 pounds. When those two vehicles meet, the injuries on the passenger vehicle side tend to be catastrophic rather than moderate: traumatic brain injury, spinal cord damage, multiple fractures, or death. That severity is why truck cases so often become wrongful death claims or lifetime care claims rather than ordinary soft tissue claims.

The second difference is the defendant list. In a two-car collision, the at-fault driver is usually the only person who owes you anything. In a commercial crash, the driver may be an employee, an owner-operator under lease, or a contractor working through a broker. Each arrangement changes who is liable in a truck accident besides the driver.

The third difference is regulation. Commercial drivers and the companies that employ them operate under the Federal Motor Carrier Safety Regulations. Those rules govern how long a driver may work, how a vehicle must be inspected, how cargo must be secured, and what records the company must keep. A violation of one of those rules is powerful evidence of negligence in a personal injury case, because the rule itself establishes the standard of care.

What counts as a commercial motor vehicle?

Federal crash reporting generally treats a large truck as any truck with a gross vehicle weight rating over 10,000 pounds, which sweeps in far more vehicles than most people expect. That category is not limited to semis pulling 53-foot trailers.

• Tractor-trailers and semis
• Box trucks and straight trucks
• Dump trucks, concrete mixers, and construction haulers
• Tanker trucks carrying fuel or hazardous materials
• Delivery vans operating for freight and parcel companies
• Buses, including transit, charter, and school buses
• Municipal vehicles such as snowplows, street sweepers, and refuse trucks

The classification matters because it determines which regulations apply, how much insurance the vehicle must carry, and in some cases which court hears the case. It is worth identifying correctly at the start of a claim rather than after a settlement demand has already gone out.

What federal rules apply to truck drivers and carriers?

The rules that matter most in personal injury cases are hours of service, vehicle inspection and maintenance, driver qualification, cargo securement, and drug and alcohol testing. The Federal Motor Carrier Safety Administration publishes all of them, and the hours of service rules sit in 49 CFR Part 395.

Hours of service limits are the ones that come up most often. A property-carrying driver may drive up to 11 hours after 10 consecutive hours off duty, must finish all driving within a 14-hour on-duty window, must take a 30-minute break after 8 cumulative hours of driving, and is capped at 60 or 70 hours over a 7 or 8 day period. When a driver blows through those limits to make a delivery window, fatigue becomes a foreseeable result rather than an accident. That is the theory behind most truck driver fatigue and hours of service violations claims.

Proving a violation is a records problem, not an argument problem. Most commercial trucks now log duty status through an electronic logging device, and the engine control module records speed, braking, and throttle input in the seconds before impact. Understanding what truck black box and ELD data shows after a crash often decides whether a case settles or goes to trial.

Why does evidence disappear faster in truck crash cases?

Evidence disappears faster in truck cases because federal record retention periods are short and the vehicle itself is a business asset the carrier wants back in service. Driver logs, dispatch records, and inspection reports all have retention windows measured in months. Once the window closes, the carrier can destroy the records legally.

The tractor and trailer create a second problem. A repaired or resold truck cannot be inspected for brake condition, tire wear, or lighting failure. Neither can the cargo be weighed or re-examined once it has been offloaded. This is why preserving evidence after a Colorado truck crash is one of the first things a lawyer does, usually through a written demand sent to the carrier and its insurer within days.

The same urgency applies on the injured person’s side of the case. Photographs of the scene, the vehicles, and visible injuries are worth more than a written description months later. Our guide on what photos to take after a crash covers the specific shots that hold up in a claim, and the process for getting a copy of a Denver police accident report is worth starting early.

How much insurance does a commercial truck carry?

Federal minimums are set by 49 CFR 387.9, and they are substantially higher than personal auto minimums.

Type of carriage	Federal minimum liability
For-hire interstate carrier, nonhazardous property, 10,001 lbs GVWR or more	$750,000
Oil and certain hazardous materials in bulk	$1,000,000
Hazardous substances in cargo tanks and certain explosives	$5,000,000

The $750,000 figure was set by the Motor Carrier Act of 1980 and has not been increased since. That single fact drives a great deal of litigation behavior, because serious injury claims routinely exceed the primary policy and reach into excess layers. Understanding why truck insurance is different from car insurance explains why carriers assign a defense team to a crash scene within hours while a personal auto insurer may take weeks to assign an adjuster.

The presence of a large policy does not mean the insurer intends to pay it. Commercial insurers evaluate the same variables discussed in how insurance adjusters decide what your claim is worth, and they add one more: whether the firm representing the injured person is prepared to try the case.

What makes Colorado truck crashes different?

Colorado adds a geographic variable that most states do not have. Interstate 70 is the only east-west interstate in the state, and it climbs through sustained grades, the Eisenhower Tunnel, and weather that changes within a single hour. According to the Colorado Department of Transportation, commercial vehicles make up roughly 10 percent of traffic on I-70.

Two Colorado-specific risks show up repeatedly in commercial crash cases:

Descending grades and brake failure. CDOT’s Truck Safety Campaign fact sheet reports that Colorado has five runaway truck ramps on the I-70 Mountain Corridor, and that the Lower Straight Creek ramp on westbound I-70 near Mile Point 212 is the most heavily used runaway truck ramp in the United States. CDOT also notes that runaway ramp use peaks in summer rather than winter, which points toward brake condition and driver technique rather than snow. That distinction matters enormously in a brake failure and runaway truck ramp crash claim, because it moves the analysis from unavoidable weather toward maintenance and training.

Traction and chain requirements. Colorado’s Must Carry Chain Law covers more than 1,400 centerline miles of highway and 130 designated chain stations, 22 of which sit on the I-70 corridor. CDOT reported more than 1,300 Must Carry citations during the 2024-2025 chain season. A carrier that sends a truck into the corridor without required equipment has made a decision, and Colorado chain law violations and truck crash liability examines how that decision is used in a personal injury case.

Colorado State Patrol has also found that 65 percent of drivers who used an I-70 truck ramp had five years or less of driving experience, which raises questions about carrier hiring, route assignment, and training. Our overview of truck crashes on the I-70 Mountain Corridor goes through those theories in detail. For passenger vehicle drivers sharing the corridor, our winter driving safety tips cover the defensive habits that matter most.

What if a government vehicle caused the crash?

A crash caused by a government-owned vehicle is still a personal injury claim, but it runs under the Colorado Governmental Immunity Act, and the deadlines and damage limits are different in ways that can end a valid case before it begins.

Under C.R.S. 24-10-109, an injured person must file written notice of the claim with the correct public entity within 182 days of discovering the injury. Missing that deadline or sending notice to the wrong entity bars the claim entirely, regardless of how strong the underlying facts are.

Recovery is also capped. The Colorado Secretary of State certifies the current limits, and for claims accruing on or after January 1, 2026 and before January 1, 2030, the certified limitation on judgments is $505,000 for injury to one person in a single occurrence and $1,421,000 where two or more people are injured, with no individual recovering more than $505,000.

These rules reach snowplows, city refuse trucks, CDOT maintenance vehicles, school buses, and public transit. If you were injured by a government vehicle in Colorado, the notice clock is the first thing to address. Transit cases have their own procedural quirks, covered in our guide to RTD bus and public transit accident claims in Denver.

How does fault get divided in a Colorado truck accident case?

Colorado uses modified comparative negligence, which means an injured person can recover damages as long as they are less than 50 percent at fault, with the award reduced by their own percentage of fault. Insurance defense teams in truck cases invest heavily in shifting a percentage of blame onto the passenger vehicle driver, because every point moved is money saved.

Common defense arguments include following too closely, sitting in a blind spot, merging late, or braking suddenly. Each of those can be tested against physical evidence, and engine data frequently contradicts the driver’s account. Our explanation of Colorado’s modified comparative negligence rule walks through how the percentages actually change a settlement figure.

How long do you have to file a truck accident claim in Colorado?

Most Colorado personal injury claims arising from a motor vehicle crash carry a three-year deadline under C.R.S. 13-80-101(1)(n), which applies to tort actions for bodily injury or property damage arising out of the use or operation of a motor vehicle.

Three exceptions matter in commercial cases:

• Claims against public entities require written notice within 182 days, well before the three-year filing deadline.
• Wrongful death claims follow their own limitation period, which is shorter than three years.
• Product liability theories against a component manufacturer, such as a defective products claim over a failed brake assembly or tire, are governed by a different statute.

The filing deadline is the outer boundary, not a target. Because the evidence problems described above start immediately, waiting until year two costs cases that would have been provable in month two. Our article on how long a personal injury case takes in Colorado sets realistic expectations for the timeline once a claim is underway.

What should you do after a truck crash in Colorado?

The immediate steps mirror any serious crash, with a few additions specific to commercial vehicles.

1. Get medical care, even if symptoms seem mild. Delayed treatment is the single most common argument insurers use to discount an injury claim.
2. Call law enforcement and make sure a report is generated.
3. Photograph the truck’s USDOT number, motor carrier name, trailer markings, and license plates on both the tractor and trailer.
4. Note whether the truck was carrying a placard indicating hazardous material.
5. Do not give a recorded statement to the carrier’s insurer before speaking with a lawyer.
6. Contact a lawyer quickly so an evidence preservation demand goes out before records age off.

Our Colorado crash checklist covers the general sequence in more detail. If the truck fled the scene or turned out to be uninsured, an uninsured motorist claim may be the path to recovery.

Why does trial readiness matter in a truck case?

Trial readiness matters more in commercial cases than in almost any other kind of personal injury claim because the defense is institutional. A motor carrier and its insurer handle these cases repeatedly, track outcomes, and price settlements according to what the opposing firm is likely to do.

Chalat Hatten & Banker has tried catastrophic injury and product cases to verdict, including a product liability judgment against Ford Motor Company and a recovery for a family struck head-on by a truck. The reason that record matters to a client is covered in our piece on why insurance companies track which law firms actually go to trial.

Frequently Asked Questions

Is a truck accident claim the same as a personal injury claim?

Yes. A truck accident claim is a personal injury claim. It simply involves an additional layer of federal regulation, more potential defendants, and larger insurance policies than a claim arising from a collision between two passenger vehicles.

Can I sue the trucking company and not just the driver?

Often, yes. A motor carrier can be responsible for the conduct of a driver acting within the scope of employment, and can also be independently negligent in hiring, training, supervision, maintenance, or scheduling.

How much is a truck accident case worth in Colorado?

No lawyer can responsibly quote a figure without reviewing the facts. Value depends on the severity and permanence of the injury, medical expenses, lost earning capacity, the available insurance, and the percentage of fault assigned to each party under Colorado’s comparative negligence rule.

What if the truck was owned by a city or the state?

The Colorado Governmental Immunity Act applies. Written notice must reach the correct public entity within 182 days of discovering the injury, and recovery is capped at the amount certified by the Secretary of State for the year the claim accrued.

Do I need a lawyer for a truck accident claim?

Commercial carriers typically deploy investigators and defense counsel to a serious crash scene within hours. An injured person acting alone is unlikely to secure engine data, driver logs, or maintenance records before those materials become unavailable.

How long do I have to file?

Generally three years for a motor vehicle personal injury claim under C.R.S. 13-80-101(1)(n). Claims against public entities, wrongful death claims, and product liability claims follow different deadlines.
