Federally reportable crashes: a fatality, an injury taken from the scene, or a tow-away. Not all crashes are the carrier’s fault.

Roadside inspections by state and federal officers. More inspections means the figures rest on more evidence.
How this page adds context to the federal record
- Percentile scales compare this carrier against fleets of similar size. The official lookup shows raw counts with no comparison.
- The activity chart rebuilds 24 months of month-by-month inspection and out-of-service history, which the official lookup reports only as a running total.
- The state list shows where its trucks were actually stopped, so you can tell whether a carrier runs anywhere near you — the official lookup does not break activity down by state.
Inspection activity, last 24 months
- Inspections with no out-of-service order
- Inspections with an out-of-service order
The share of inspections producing an out-of-service order held steady at 4.9% over the most recent 12 months, from 4.0% in the 12 months before that.
Fleet size unchanged across snapshots from 2026-08-12 to 2026-08-22 — 1,049 power units. A fleet-size chart appears here once it moves.
Where its trucks were inspected
States where this carrier’s trucks were stopped for inspection over the last 24 months — a rough guide to where it runs, and a way to see whether it operates near you. Inspection counts also reflect how heavily each state enforces, so a high count is not by itself evidence of more miles driven there.
Shading is relative to this carrier’s own busiest state, not to other carriers.

Figures labelled as computed on this page are calculated by CarrierRanked from public FMCSA inspection, violation and crash records. They are not FMCSA Safety Measurement System percentiles, not CSA scores, and not a federal safety rating under 49 U.S.C. § 31144. CarrierRanked is not affiliated with, endorsed by, or sponsored by FMCSA or the U.S. Department of Transportation.
Readers should not draw conclusions about a carrier’s overall safety condition simply based on the data displayed here. Unless a motor carrier has received an UNSATISFACTORY safety rating under 49 C.F.R. Part 385, or has otherwise been ordered to discontinue operations by FMCSA, it is authorized to operate on the nation’s roadways.
