Commercial truck insurance in Colorado: what the state adds
Colorado doesn't publish one number for truck insurance. Your minimum depends on what you haul and for whom, and some of the choices that shape your policy are made on Colorado forms that many owners sign without a second look.

Colorado truck insurance in numbers
Commercial truck insurance in Colorado starts at $750,000 in liability for for-hire general freight, whether the load crosses state lines or stays in Colorado, and more for hazmat. Colorado-only carriers also need $10,000 in cargo coverage per truck, and Colorado policies carry UM/UIM and medical payments coverage unless you reject them in writing.
Most questions about Colorado truck insurance start with the federal number. That's the right place to start, but Colorado adds rules of its own: a cargo minimum for in-state loads, coverage choices you make in writing, a lease law aimed at owner-operators, and, since 2025, much higher damage caps in injury lawsuits.
I spent more than six years in risk management before I founded Simplex, and I've led it for more than 25 years since. This guide covers what Colorado adds to the federal rules, and why the state's lawsuit rules make the minimum a starting point rather than a target.

Key takeaways
Colorado applies the federal minimums at home
Colorado State Patrol rules apply the federal insurance rules to Colorado-only carriers, so a for-hire truck hauling general freight needs $750,000 whether or not it leaves the state.
In-state loads need cargo coverage
Colorado-only carriers must carry at least $10,000 in cargo coverage per truck, or the load's value if that's less, unless the shipper agrees in writing to a lower amount.
Two coverages take a signature to drop
Your insurer must offer UM/UIM up to your liability limit and include $5,000 in medical payments coverage. Each stays on the policy unless the named insured rejects it in writing.
Leased owner-operators need accident coverage
Leases under Colorado's owner-operator statute must provide workers' comp or an occupational accident policy, with at least a $1.5 million aggregate limit for commercial vehicle operators.
The lawsuit ceiling went up
Since January 1, 2025, Colorado caps noneconomic damages at $1.5 million in injury cases and $2.125 million in wrongful death cases, both above a $750,000 policy.

What commercial truck insurance does Colorado require?
Auto liability, at a level set by what you haul and for whom. For-hire general freight needs $750,000 whether it crosses state lines or not, because Colorado State Patrol rules apply the federal insurance rules in 49 CFR Part 387 to Colorado-only carriers too.
| Operation | Who sets the rule | Minimum liability |
|---|---|---|
| Interstate for-hire general freight, 10,001 pounds or more | FMCSA, under 49 CFR 387.9 | $750,000 |
| Colorado-only for-hire general freight | Colorado State Patrol, adopting 49 CFR 387 | $750,000, plus $10,000 cargo per truck |
| Hazmat, interstate or Colorado-only | FMCSA and Colorado State Patrol | $1 million or $5 million, by material |
| Private fleet hauling its own nonhazardous goods | Colorado auto insurance law | $25,000/$50,000/$15,000 basic minimum |
| Towing and household goods moving | Colorado Public Utilities Commission permit | Set by PUC rules; your insurer files it |
The state rules reach Colorado-only trucks that meet Colorado's commercial vehicle definition: a rating of 16,001 pounds or more, or apportioned plates. The $25,000/$50,000/$15,000 limit in C.R.S. 10-4-620 is the basic floor for any vehicle, not a trucking number.
Tow companies and household goods movers answer to the Colorado Public Utilities Commission, which permits them and sets their insurance minimums. For interstate authority, your insurer files proof with FMCSA within 20 days of your application's publication in the FMCSA Register; our guide to insurance for a new trucking company walks through that first filing.
Do Colorado-only loads need cargo insurance?
Yes, a minimum. Colorado-only carriers must carry at least $10,000 in cargo coverage for loss or damage to the property on any one truck, or enough to cover the load's value if that's less, unless the shipper agrees in a written contract to a lower amount.
That's a Colorado rule. Federal rules require cargo coverage only of household goods movers, so on interstate general freight the cargo limit is a contract term set by the broker or shipper.
Treat $10,000 as a legal floor, not a target: a single load of machinery or refrigerated food can be worth many times that, and the contract you sign sets its own number. Read our guide to what motor truck cargo insurance covers and excludes before you match a limit to a contract, because commodity exclusions matter as much as the limit.
Which Colorado coverages must you accept or reject in writing?
Two: uninsured/underinsured motorist coverage and medical payments coverage. Colorado law puts both on a policy issued in the state unless the named insured rejects them in writing, and the choice you make carries forward to renewals.
Uninsured and underinsured motorist
Before a policy is issued or renewed, your insurer must offer UM coverage up to your bodily injury liability limit, under C.R.S. 10-4-609. It includes underinsured drivers, and it pays on top of the at-fault driver's own liability coverage, up to your UM limit.
It protects the people insured under your policy, such as your driver, when the other vehicle carries too little insurance. Once you've chosen limits or declined, the insurer doesn't have to offer it again at renewal, though you can ask in writing for more.
Medical payments
C.R.S. 10-4-635 builds $5,000 in medical payments coverage into Colorado auto policies. It comes off only if the named insured rejects it in writing or in the same medium the application was taken, and if the insurer can't prove the rejection, the policy is presumed to include it.
Neither decision should happen by default in a renewal packet. Ask your agent which forms you signed on your commercial auto liability policy and what limits they set.
How does Colorado workers' comp apply to truck drivers?
If you have employees, you need it. Colorado requires workers' comp of nearly every employer, treats workers as employees unless proven otherwise, and says plainly that paying someone on a 1099 doesn't make them a contractor.
- Running uninsured: fines of up to $500 for each day without coverage, and the business can be shut down.
- An injury while uninsured: you pay the claim yourself, plus a penalty of 25% of the injured worker's benefits.
- Owners: corporate officers and LLC members who own at least 10% of the company can reject coverage for themselves on the state's form.
Leased owner-operators
Colorado has its own statute for leases between carriers and owner-operators, C.R.S. 40-11.5-102. A lease under it must provide workers' comp or an occupational accident policy with similar coverage, and must say whether the carrier or the owner-operator pays for it.
For commercial vehicle operators, a qualifying occupational accident policy needs an aggregate limit of at least $1.5 million for medical, disability, death and dismemberment, and survivor benefits. An operator who elects it falls outside the employee definition, must notify the state's Division of Workers' Compensation, and must show proof on request.
Occupational accident insurance is not health insurance; our guide to health insurance for owner-operators explains where each one fits.
Why is the minimum only a floor in Colorado?
Because Colorado raised what a jury can award. A judgment above your liability limit is your company's to pay, and House Bill 24-1472 lifted the state's damage caps for claims that arise on or after January 1, 2025.
- Injury cases: the cap on noneconomic damages, such as pain and suffering, is $1.5 million.
- Wrongful death: noneconomic damages are capped at $2.125 million.
- Inflation: both caps adjust every two years, starting January 1, 2028.
These caps limit noneconomic damages only. Medical bills, lost earnings, and property damage are outside them, so a $750,000 policy can sit well below what a serious injury claim seeks.
Claims also take time to arrive. Colorado gives injured people three years to sue over a motor vehicle crash under C.R.S. 13-80-101, so keep the driver file, inspection records, and logs tied to any crash at least that long.
Mountain corridors add their own exposure: long grades, winter chain stops, and traffic that can't get around a stopped truck. Our guide to mountain driving for truckers covers Colorado's chain law.
How much is commercial truck insurance in Colorado?
There is no posted rate. Each insurer prices your operation: radius and lanes, commodities, the trucks and their values, each driver's record and experience, your loss history, your safety record, the limits you choose, and your deductibles.
Lanes matter in Colorado. A Denver or Colorado Springs metro route, an I-70 mountain run, and an eastern plains route carry different exposures, so describe the lanes you actually run instead of a radius alone.
Choose the limit before you shop the price. Start with the minimum for your operation, read each broker, shipper, and lease agreement for its own limits, then weigh Colorado's higher damage caps. Our guide to what commercial truck insurance costs breaks down the pricing factors.
When you compare quotes, compare the same limits, deductibles, exclusions, and UM and medical payments choices. A cheaper policy with a gap isn't cheaper on the day you need it.
