Safety record

A
Strong

Grade shown here is ProHRHQ analysis based on public FMCSA data. It is not an official FMCSA safety rating. The authoritative federal record is on FMCSA SAFER/SMS.

Current peer-cohort snapshot based on public FMCSA BASIC measures. Peer cohort: 320 motor carriers operating 63 power units.

No acute or critical violation flags in the current review window.

The key signal in this record is Vehicle Maintenance at 209.4% of peer cohort average — roughly double the norm and the dominant reason for the A grade. Main caution: vehicle maintenance is the weakest area of the record and warrants direct confirmation with the carrier.

BASIC Carrier (3yr, weighted) Cohort avg vs. cohort Acute
Unsafe Driving 29 28.05 103.4% No
Hours-of-Service 0 12.14 0.0% No
Driver Fitness 0 5.37 0.0% No
Controlled Substances/Alcohol 0 0.00 No
Vehicle Maintenance 177 84.52 209.4% No
Hazmat 0 2.25 0.0% n/a

Against similarly sized 63-power-unit peers, this carrier is below cohort average in Hours-of-Service and Driver Fitness, and above cohort average in Vehicle Maintenance.

ProHRHQ analysis · derived from federal cargo, route, and fleet fields

What this carrier likely fits

This is a waste hauler that runs local lanes, primarily intrastate, at a mid-sized fleet scale, with garbage, refuse, trash on the FMCSA cargo classification list. Trailer-heavy fleet composition (97 trailers against 63 tractors) is consistent with drop-and-hook or dedicated lane operation.

Drawn from FMCSA-reported cargo classifications, route profile, and fleet composition. Not a substitute for direct confirmation of equipment and lane capability with the carrier.
