Showing the 25 most recent of 45 total reported crashes.

These records report that a commercial vehicle registered to this carrier was involved in a crash meeting FMCSA's reporting threshold. The FMCSA Crash File does not assign fault and does not determine preventability: a crash caused entirely by another road user appears here on the same terms as one caused by this carrier's driver. See how FMCSA crash reporting works for what these records do and do not establish.
