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 Calmat Co'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 Calmat Co 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
11,993 mi
Lower utilization often seen with local, dedicated, or specialty operations (2024 data).
Inspections per Power Unit
0.6
Lower inspection activity, sometimes seen with local or low-mileage operations.
Crashes per 1,000 Units
134.8
Significantly above industry average (3.2 per 1,000 units).

What is a normal OOS rate?
The national average vehicle out-of-service rate is approximately 21%. The driver OOS average is closer to 5.5%. Rates well above these benchmarks may indicate recurring compliance issues. Lower rates suggest stronger maintenance and driver-qualification programs.
How many crashes has Calmat Co been involved in?
FMCSA records 12 reported crashes for Calmat Co over a rolling 24-month window, including 0 fatal, 8 injury, and 12 tow-away crashes. Crash counts include both preventable and non-preventable events. Always evaluate raw counts against fleet size and miles driven.
How large is Calmat Co's fleet?
Calmat Co operates 89 power units (trucks and tractors) and reports 89 drivers on their FMCSA MCS-150 form. Fleet figures are self-reported and updated biennially, so the live operational fleet may differ slightly.
Where is Calmat Co located?
Calmat Co is headquartered in Irwindale, California at 16013 E Foothill Blvd. They operate in interstate commerce across state lines.
What does a satisfactory safety rating mean?
A Satisfactory rating is the highest rating issued by FMCSA following a compliance review. It means Calmat Co demonstrated adequate safety management controls during the review. Only about 1-2% of all registered carriers hold a formal safety rating, since FMCSA only rates carriers that go through a compliance review.
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 Calmat Co for changes?
If you tender loads to Calmat Co 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.
Where does this data come from?
All data on this page is sourced from the Federal Motor Carrier Safety Administration (FMCSA) via the DOT Open Data Portal. It includes the Company Census File, roadside inspection records, crash reports, and SMS/BASIC safety scores. Data is self-reported by carriers and updated regularly by FMCSA. For the authoritative single-source-of-truth record, cross-reference with FMCSA SAFER.
