Trucking companies in Denver: local haulers, movers and the mountain rules every carrier must know

This report is for shippers and builders looking for a Denver carrier, drivers comparing employers, and B2B sellers whose customers are trucking companies: winter equipment and tire suppliers, repair shops, insurers and software vendors.

Denver trucking in Census data

County Business Patterns 2023 covers NAICS 484 (Truck Transportation) in the Denver-Aurora-Centennial, CO Metro Area (CBSA 19740).

A local market

Pay per employee is our calculation. In most of the markets we cover, long-distance truckload is the biggest group; in Denver local general freight edges it out. Movers are a real industry here, with 133 establishments and 2,156 employees, more employees than local general freight's 1,905. Less-than-truckload terminals hold a quarter of the jobs and pay the most, about $71,900.

The Census Bureau doesn't publish the two largest size classes here. Subtracting the published classes from the total leaves 27 establishments with 100 or more employees, two of them with 500 or more. In broader bands: 1,044 have 1 to 19 employees and 98 have 20 to 99.

Adams County and the rest

Adams County, home to Commerce City and Brighton, has 36% of the establishments and 63% of the jobs, at almost 19 employees per site. Arapahoe County is mostly small operators, about 5 employees per site. The Census Bureau published Jefferson and Park counties' employee totals but flagged them as high-noise (the noise added for confidentiality moved them by 5% or more), so we leave them out.

These figures count establishments with paid employees. Owner-operators without staff, construction companies' own dump trucks and other private fleets aren't included, and a carrier's yards count one by one.

What the register shows

FMCSA's Company Census File, updated 29 October 2026, lists 11,210 active for-hire carriers with at least one truck in the metro's ten counties, 8,180 of them intrastate. Only 4,481 updated their self-reported MCS-150 filing in the past two years, and 8 more large fleets reported fewer drivers than a tenth of their power units, so we left them out. Of the 4,481, 2,027 (45%) are intrastate only, 2,728 (61%) run one power unit and 599 (13%) list household goods, against 32% and 9.4% of current for-hire registrations nationally. Cargo types are self-reported by carriers, and FMCSA's open-data file doesn't always match a carrier's own SAFER record, so treat the household goods share as indicative.

We left out a waste hauler, a county government and a brewer's distribution fleet, all registered for hire. No Denver-based for-hire carrier reports more than 600 power units and no SEC-listed trucking company is headquartered in the metro, so most of the big fleets you'll see on Denver roads are based elsewhere.

The mountain rules

The Colorado Department of Transportation says its Traction Law is in effect on I-70 between Dotsero and Morrison from September 1 to May 31. Under the Chain Law, the last step before CDOT closes a highway in a severe storm, every vehicle must have chains or an approved alternative traction device. CDOT lists fines of $100 plus a $33 surcharge for not complying, and $500 plus a $157 surcharge if non-compliance leads to a lane closure, and it notes separate rules for commercial vehicles. A carrier running west of Denver in winter needs chains on the truck and drivers who can fit them.

Traffic is the other constraint. The American Transportation Research Institute's 2026 bottleneck ranking includes four Denver locations:

All four sit on the north side of the metro, between downtown and Adams County.

Checking a Denver carrier

1. Search the USDOT number in FMCSA's SAFER Company Snapshot and note whether it's registered for interstate or intrastate work.
2. If the load crosses state lines, check authority and insurance in Licensing and Insurance.
3. For mountain lanes in winter, ask how the carrier handles traction and chain law days and how it reschedules when I-70 closes.
4. For a household move, confirm the mover lists household goods on its FMCSA filing and get a written estimate.
5. Ask for a certificate of insurance and references from shippers on the same lanes.

Selling to Denver trucking companies

The calendar is the trigger: traction law season starts on September 1, so winter equipment and driver training sell in late summer. For your opening message, see how to write a cold email.

Illustrative example. The supplier and its numbers are invented; the counts are FMCSA register data and CDOT dates.

Front Range Chain Supply (frontrangechain.example) sells chains and alternative traction devices and runs a one-hour chain-up class at the carrier's yard. Its list is the metro's 559 current interstate for-hire carriers with 3 to 50 power units, the fleets most likely to run I-70 west and least likely to have a winter program. With one contact each (owner or safety lead) and a 6% reply rate, that's 34 conversations; if one in three books a class in August, 11 fleets, most of which order a full set of chains afterward. Bebop can pull those carriers from a plain-language description and research each one.

Subject: Chain law season for [company]'s drivers

Hi [first name],

[Company] runs [number] trucks out of [city] and is registered for interstate work, so I'd guess some of your loads go west on I-70.

Colorado's traction law season starts September 1. We fit each truck with chains or an approved traction device and spend an hour with your drivers on fitting them in the cold.

Would a class at your yard in [month] be useful?

[Your name]
