Is this carrier bookable?
Nothing here stands out as an immediate reason not to use this carrier.
Six things go into this read of Polzer Bros Inc'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
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 Polzer Bros Inc 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
0.44
Lower than one driver per truck suggests owner-operators or part-time drivers.
Miles per Power Unit
3,333 mi
Lower utilization often seen with local, dedicated, or specialty operations (2025 data).
Inspections per Power Unit
0.3
Lower inspection activity, sometimes seen with local or low-mileage operations.
Crashes per 1,000 Units
0.0
Below industry average (3.2 per 1,000 units).

Insurance history
Every insurance filing FMCSA has on record for Polzer Bros Inc, up to the 25 most recent including cancelled policies. Each row shows the form type, the insurance company, when the policy went into effect, and when (or if) it was cancelled. Common things brokers look for: a recent cancellation with no replacement on file (the carrier may not have valid coverage right now), repeated short-lived policies with different insurers (instability), and the actual coverage amount versus the freight value.

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.
Is zero crashes always a good sign?
Generally yes, but context matters. A carrier with zero recorded crashes and very few inspections may simply have limited road exposure. Look at Polzer Bros Inc's inspection volume and fleet size alongside the crash count to judge whether the safety record reflects a strong operation or just low activity.
How large is Polzer Bros Inc's fleet?
Polzer Bros Inc operates 9 power units (trucks and tractors) and reports 4 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 Polzer Bros Inc located?
Polzer Bros Inc is headquartered in Durand, Wisconsin at W6829 US Hwy 10. 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 Polzer Bros Inc 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 Polzer Bros Inc for changes?
If you tender loads to Polzer Bros Inc 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.

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.
