How to verify SOUTHERN WISCONSIN CONTRACTING LLC

  1. Verify USDOT and MC numbers match the carrier's documents. Compare the USDOT number and MC docket on this page to the numbers on the carrier's invoice, rate confirmation, or load-board listing. A mismatch between the carrier's claimed numbers and the registered legal name is the single most common red flag.
  2. Check active operating authority and insurance status. Confirm the Authority Records show at least one ACTIVE docket for the type of operation you're booking, and that the Active Insurance card lists a current BIPD/Primary policy. A revoked authority or uninsured carrier cannot legally operate.
  3. Review safety rating and SMS BASIC scores. Check the carrier's FMCSA safety rating (if any) and the SMS BASIC table. A high percentile in any BASIC category — especially Unsafe Driving, HOS, or Vehicle Maintenance — is worth investigating before tendering a load.
  4. Examine inspection and crash history. Open the Inspection History and Crash History subpages for the full record. Look for patterns: repeat OOS findings on the same unit, multiple crashes in a short window, or violations clustered in one BASIC category.
  5. Cross-reference real-time data with FMCSA SAFER. For the most current snapshot — within 24 hours of any insurer filing or authority change — click through to the FMCSA SAFER lookup. TruckCodex mirrors SAFER and L&I daily; SAFER itself reflects filings within 24 hours.

Frequently asked questions about SOUTHERN WISCONSIN CONTRACTING LLC

Is SOUTHERN WISCONSIN CONTRACTING LLC an active motor carrier?
Yes. SOUTHERN WISCONSIN CONTRACTING LLC is registered with the FMCSA under USDOT 1473930 and is currently shown as Active in the agency's Motor Carrier Management Information System (MCMIS). Active status means the carrier may legally operate, contingent on continuous insurance and authority filings.
What is SOUTHERN WISCONSIN CONTRACTING LLC's safety rating?
SOUTHERN WISCONSIN CONTRACTING LLC is unrated. FMCSA assigns formal safety ratings only after a compliance review, and the agency has not yet completed one for this carrier. Being unrated is not by itself a red flag — most active carriers in the database are unrated. Review the inspection and BASIC data below to assess on-road performance.
How many inspections has SOUTHERN WISCONSIN CONTRACTING LLC had?
18 roadside inspections are on file for SOUTHERN WISCONSIN CONTRACTING LLC in FMCSA's MCMIS database. Each inspection is summarized in the Inspection History section below — sortable by date, state, level, and out-of-service result. Newer inspections are pulled from the FMCSA SMS data feed daily.
What is SOUTHERN WISCONSIN CONTRACTING LLC's out-of-service rate?
SOUTHERN WISCONSIN CONTRACTING LLC has no out-of-service findings on its inspection record. Across 18 inspections, no driver or vehicle has been placed out of service — a clean record relative to the national averages of roughly 6.7% (driver) and 23.4% (vehicle).
Where is SOUTHERN WISCONSIN CONTRACTING LLC based?
SOUTHERN WISCONSIN CONTRACTING LLC reports its physical address to the FMCSA as 400 1ST AVE, MONROE, Wisconsin 53566. Carriers must file a Form MCS-150 every two years to keep their address current; an outdated address is a common compliance flag.
Does SOUTHERN WISCONSIN CONTRACTING LLC have valid operating authority?
Yes. SOUTHERN WISCONSIN CONTRACTING LLC holds 1 active FMCSA operating authority (MC701680). Each docket appears in the Authority Records section below with its full event history. Active authority means the carrier may legally operate as a for-hire carrier, contingent on current insurance and BOC-3 process-agent filings.
How many trucks and drivers does SOUTHERN WISCONSIN CONTRACTING LLC operate?
SOUTHERN WISCONSIN CONTRACTING LLC self-reports 12 power units and 8 drivers on its most recent FMCSA Form MCS-150 filing. Power-unit and driver counts come from the carrier directly and are required to be updated every two years; very large fluctuations between filings can indicate fleet changes worth investigating.
Has SOUTHERN WISCONSIN CONTRACTING LLC had any crashes?
2 FMCSA-reportable crashes are on file for SOUTHERN WISCONSIN CONTRACTING LLC in MCMIS. A reportable crash is one resulting in a fatality, an injury requiring transport for medical attention, or a vehicle disabled and towed from the scene. The full crash log is on the Crashes subpage with date, state, and outcome details.

About FMCSA carrier records

Every commercial motor carrier operating in the United States is required to register with the Federal Motor Carrier Safety Administration (FMCSA) and obtain a USDOT number. The USDOT number is a permanent, unique identifier — once assigned, it stays with the carrier for life and is never reissued to another company. Carriers must update their registration every two years on Form MCS-150 to keep their address, fleet size, and operating data current.

Carrier safety data lives in FMCSA's Motor Carrier Management Information System (MCMIS): roadside inspections, crashes, out-of-service findings, and the seven Behavior Analysis and Safety Improvement Categories (BASICs) that make up the SMS scoring methodology. For-hire carriers must also hold operating authority — an MC, FF, or MX docket number — which is separate from the USDOT number and requires continuous insurance and BOC-3 process-agent filings to remain active.

TruckCodex mirrors FMCSA's public SAFER and L&I systems on a daily refresh cycle. Every record on this page reflects what FMCSA has on file. We do not edit or modify carrier data — for real-time confirmation immediately before a transaction, click through to the FMCSA SAFER lookup linked in the related records section above. Safety ratings, when present, come from formal compliance reviews; most active carriers have not been reviewed and are correctly listed as unrated.
