CIS subtotal normalizes 3 publicly-available FMCSA components (Safety Rating + Inspection Pass Rate + OOS Rate) to a 0-100 surface. CSA SMS BASIC percentiles are not published in FMCSA's public Socrata datasets and the SMS portal at ai.fmcsa.dot.gov is not crawlable at scale, so we surface a transparent "Not measured" rather than fabricate a score component. Carriers with a Compliance Review on record may have published BASIC data on the SAFER snapshot for that DOT.
SUKUP MANUFACTURING COMPANY is a mid-size fleet operating out of SHEFFIELD, Iowa with USDOT number 1829. The company operates 68 power units and holds a current FMCSA safety rating of Conditional. Based on our analysis of federal safety data, SUKUP MANUFACTURING COMPANY has a FileFlo Carrier Intelligence Score (CIS) of 58/100, classified as Elevated Risk.
SUKUP MANUFACTURING COMPANY has undergone 37 recorded DOT inspections. The vehicle out-of-service rate is 10.8%, which is below the national average of 20.72%, suggesting solid vehicle maintenance practices.
The public FMCSA record for SUKUP MANUFACTURING COMPANY carries 24 recorded violations, and the most recent inspection on file is dated 20260812. Across 37 recorded inspections, the record carries 0 driver out-of-service violations and 5 vehicle out-of-service violations.
A recorded violation is what an inspector wrote down at the roadside. It is not a penalty, and it is not an amount owed: FMCSA assesses civil penalties only after a compliance review classifies specific cited violations. The step that changes this record is the document behind each line, so the next move is to see which records an investigator would ask for and which of them exist today.
A CIS score of 58 places SUKUP MANUFACTURING COMPANY in the Elevated Risk category. Carriers at this level are more likely to be selected for compliance reviews and roadside inspections. Immediate attention to driver qualification files, hours-of-service records, and vehicle maintenance logs is recommended.
Motor carriers operating in Iowa must comply with both federal FMCSA regulations and state-specific transportation requirements. The SHEFFIELD, IA corridor is monitored by FMCSA field offices and state highway patrol units conducting roadside inspections. Carriers based in SHEFFIELD should ensure driver qualification files, vehicle inspection reports, and hours-of-service records are current and audit-ready at all times.
SUKUP MANUFACTURING COMPANY falls under the Midwestern Service Center for FMCSA field-office oversight (region code 07). Service-center territory drives which FMCSA Investigator team would conduct a new-entrant audit or compliance review if one is triggered for this carrier.
FileFlo helps Iowa trucking companies automate compliance document tracking across 600+ document types, including CDL medical cards, annual vehicle inspections, drug & alcohol testing records, and driver training certifications.
SUKUP MANUFACTURING COMPANY is classified by FMCSA as an interstate carrier.
The carrier is classified as Private Property, meaning it transports its own goods incidental to its primary business, exempt from MC-number authority but still subject to safety regulations under 49 CFR Part 390.
Business organization type: Corporation.
SUKUP MANUFACTURING COMPANY is not flagged in FMCSA Census as a hazmat carrier (HM indicator: N), so the carrier is not subject to the additional 49 CFR Subchapter C hazmat regulations.
Operational range per MCS-150 filing: interstate beyond 100 miles (long-haul, 48 drivers). The 100-mile boundary matters because drivers operating within a 100-air-mile radius qualify for the short-haul exception under 49 CFR 395.1(e)(1), which removes the requirement to maintain RODS for the day.
Self-reported MCS-150 annual mileage: 1,371,854 miles. MCS-150 mileage feeds the FMCSA SafeStat exposure denominator: drastically understated mileage can artificially inflate CSA BASIC percentile scores by reducing the per-mile exposure baseline. Updates are required every 24 months under 49 CFR 390.19.
Owned equipment per the FMCSA Census filing: 47 straight trucks, 20 tractors, 93 trailers. Owned-vs-leased equipment matters for compliance documentation, owned trailers require the carrier to retain annual inspection certificates under 49 CFR 396.17, while leased trailers shift that documentation responsibility to the lease agreement.
The carrier reports 28 CDL-holding drivers on file. Each CDL driver must have a current Driver Qualification File (DQF) maintained per 49 CFR 391.51, including a Medical Examiner's Certificate, an annual MVR review, and a record of road-test results.
Primary cargo type per MCS-150: Fabricated Products. Cargo type drives which BASIC categories the carrier is monitored under (Hazmat Compliance applies only to HM-flagged carriers; Cargo-Related Crash applies broadly).
The FMCSA Motor Carrier Management Information System (MCMIS) crash dataset records 20 crash events involving SUKUP MANUFACTURING COMPANY in the available reporting window. Of these, 0 involved a fatality, 7 involved a reported injury, and 20 resulted in a tow-away. 20 events meet the federal-recordable threshold under 49 CFR 390.5 (fatality, injury treated away from the scene, OR tow-away of any vehicle).
Federal-recordable crashes feed the Crash Indicator BASIC in CSA: carriers above the intervention threshold are 7-10x more likely to be selected for a compliance review than peer carriers below the threshold. Insurance carriers also pull federal-recordable crash counts during quoting; a single recordable crash in a 24-month look-back can drive a 10-20% premium increase for owner-operators and small fleets.
Most recent recorded event: I-74, Empire Twp, IL on 20250916.
Inspections cluster geographically across Iowa (16), South Dakota (4), Indiana (4). The concentration in Iowa is consistent with the carrier's primary lanes and tends to correlate with which state DOT inspector teams SUKUP MANUFACTURING COMPANY's drivers encounter most often at roadside checkpoints.
Across the 37 recorded inspections, SUKUP MANUFACTURING COMPANY's 10.8% vehicle out-of-service rate sits slightly below the FMCSA 2024 national average of 20.72%. The 0.0% driver out-of-service rate sits materially below the 2024 national average of 5.51%. Vehicle OOS-rate variance is the strongest predictor of Vehicle Maintenance BASIC scores in CSA; driver OOS-rate variance is the strongest predictor of Hours-of-Service Compliance + Driver Fitness BASIC scores.
FMCSA's intervention thresholds (the percentile bands that trigger investigator outreach) are roughly 65th percentile for non-passenger non-hazmat carriers (75th for hazmat, 70th for passenger) on each BASIC. Carriers that consistently sit above the national average across multiple BASICs accumulate intervention risk faster than carriers with mixed performance. A single high BASIC alone rarely triggers enforcement; sustained over-threshold performance does.
