America's Largest Trucking Companies, Ranked by Federal Crash Data

The raw totals largely track fleet size — the biggest fleets log the most miles, so they record the most crashes. That is expected, and it is why the per-1,000-trucks view exists alongside it.

The rate view shows a wide spread, from 29 to 182 recorded crashes per 1,000 power units. Several structural factors can contribute to differences like these. Owner-operator networks record fleet counts differently than company fleets. Less-than-truckload carriers make frequent short hauls with many stops; longhaul truckload fleets accumulate highway miles. Refrigerated and expedited freight runs on tighter schedules. Regional exposure, weather, and freight lanes all differ. The numbers are the numbers — the reasons behind them vary by carrier, and this page does not assign them.

Source. Every figure on this page comes from FMCSA records published through its SAFER system (safer.fmcsa.dot.gov), the federal government's public motor carrier database. Crash counts reflect the trailing 24-month window and carry FMCSA's data-as-of date of September 13, 2026. Figures were retrieved on September 15, 2026.

What counts as a crash. FMCSA records reportable crashes involving a carrier's vehicles in three categories: fatal, injury, and tow-away. These are counts of recorded events. FMCSA states that no determination of crash responsibility is implied — a recorded crash does not mean the truck or its driver was at fault.

One record per carrier. Figures are drawn from each carrier's primary USDOT registration — the active record carrying its principal fleet. Large carriers can hold multiple USDOT registrations across subsidiaries and affiliates; those additional records are not combined here. Fleet sizes (power units) are as reported to FMCSA on each carrier's most recent MCS-150 filing.

Which carriers appear. The list covers the largest and most widely recognized national motor carriers across the industry's major segments. It is not a ranking of every US fleet, and inclusion reflects prominence, not any judgment about any company.

Updates. FMCSA data changes continuously as its 24-month window rolls forward. This page is refreshed on an annual cycle; figures shown reflect the data-as-of date above.

Commercial trucks share every mile of Arizona's interstates with passenger vehicles, and crashes involving them tend to involve serious forces, federal regulations, and commercial insurance policies — which makes truck accident claims in Arizona different from ordinary car accidents from the first day. Evidence like driver logs, onboard data, and inspection records exists because of the same federal system that produced the numbers on this page, and it can matter in an injury claim. For plain-English definitions of the terms that come up along the way, our Arizona injury glossary explains them.
