Is this carrier bookable?
Nothing here says automatic no, but there is enough to check before you tender a load.
Six things go into this read of Windmill Septic 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.

Fleet profile
Owner-operator / very small (under 10 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 Windmill Septic 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.

What does "Not Rated" mean?
"Not Rated" means FMCSA has not conducted a formal compliance review for this carrier. It does not indicate a safety problem on its own. The vast majority of registered carriers operate without a formal rating because compliance reviews are typically only triggered by elevated risk indicators, complaints, or scheduled audits. Use BASIC scores, inspection history, and crash records to evaluate unrated carriers.
How often is FMCSA data updated?
FMCSA refreshes carrier census data daily. Inspection and crash records are typically published within 30 days of the underlying event. Safety ratings and BASIC scores update on FMCSA's monthly cycle. The "last checked" timestamp at the bottom of this page shows when the most recent FMCSA poll happened.
Should I monitor Windmill Septic LLC for changes?
If you tender loads to Windmill Septic LLC regularly, monitoring is worth considering. Operating authority can lapse, insurance can drop, and safety ratings can change between bookings. Email alerts surface those changes the moment FMCSA publishes them, so you find out before your next load instead of after a problem on the road.
