Inspection & crash map
live · FMCSA MCMISEvery inspection and crash on record — hover a point for the summary, click for full detail (codes, severity, CSA points).
CSA points = violation severity weight × FMCSA time weight (3× in the last 6 months, 2× at 6–12, 1× at 12–24). Points are spread within each state — FMCSA records the inspection state, not an exact location. Source: FMCSA MCMIS.

Connections
carrier graphThis carrier shares officers with 35 other carriers — review the connections below as part of your vetting.
Shared VINs come from FMCSA roadside-inspection records — a vehicle inspected under more than one carrier, often a fleet transfer or trailer interchange. Other links come from the FMCSA census. Shared identifiers are common and often legitimate — treat these as leads to investigate, not proof of wrongdoing.
