Inspections and crashes

Last 24 months · FMCSA Vehicle Inspection File and Crash File

No roadside inspections or reportable crashes are on file for this USDOT number in the last 24 months.

FMCSA safety rating: Satisfactory (rated December 17, 2008)

Inspection and crash counts come from FMCSA records and are shown as reported. They are not a safety rating. A crash record does not mean the carrier was at fault. FMCSA has not rated a carrier unless a safety rating is listed. For FMCSA’s own data and its explanation, see the FMCSA SAFER Company Snapshot.

Out-of-service rates are calculated by CheckTrucking from inspection records (driver: levels I, II, III, VI; vehicle: levels I, II, V, VI). They are not FMCSA scores.
