Is this carrier bookable?

Review First

Nothing here says automatic no, but there is enough to check before you tender a load.

Six things go into this read of Kolb Grading LLC's record: operating authority, out-of-service status, insurance filings, safety rating, BASIC percentile scores, and MCS-150 freshness. Every one of them comes straight from the public FMCSA record. None of them tell you how the carrier handles damage claims or hits delivery windows, so always pull a fresh insurance certificate from the carrier and confirm rates and contact details on a current rate confirmation before you tender.

BASIC safety scores

FMCSA grades every carrier across seven safety categories called BASICs (Behavior Analysis and Safety Improvement Categories). Each score is a percentile from 0 to 100, calculated from the carrier's roadside inspections, crash reports, and investigation results over a rolling 24-month window. Higher scores mean more recorded violations relative to similar carriers. Scores at or above 75 can flag a carrier for FMCSA intervention and are worth a closer look before tendering. Scores below 65 sit within normal range.

Fleet profile

Small fleet (10–99 units)

Raw fleet counts only tell you so much about a carrier. A 100-truck fleet with 300 drivers is almost certainly running team or multi-shift over-the-road operations. A 100-truck fleet with 90 drivers is more likely owner-operators, regional, or local work. The ratios below are calculated from FMCSA fleet, mileage, and inspection data and show you how Kolb Grading LLC actually runs day to day. That helps you judge whether their capacity, utilization, and safety performance match the kind of load you're looking to tender.

Drivers per Power Unit

1.00

Roughly one driver per truck. Typical for regional or local fleets.

Miles per Power Unit

11,449 mi

Lower utilization often seen with local, dedicated, or specialty operations (2024 data).

Inspections per Power Unit

0.3

Lower inspection activity, sometimes seen with local or low-mileage operations.

Crashes per 1,000 Units

478.3

Significantly above industry average (3.2 per 1,000 units).
