ZST INC: KINZERS, Pennsylvania Trucking Company
ZST INC is a small fleet operating out of KINZERS, Pennsylvania with USDOT number 847252. The company operates 8 power units and holds a current FMCSA safety rating of Satisfactory. Based on our analysis of federal safety data, ZST INC has a FileFlo Carrier Intelligence Score (CIS) of 97/100, classified as Low Risk.
FMCSA Safety Record & Inspection History
ZST INC has undergone 24 recorded DOT inspections. The vehicle out-of-service rate is 4.2%, which is below the national average of 20.72%, suggesting solid vehicle maintenance practices. The driver out-of-service rate is 4.2%, within acceptable range compared to the 5.51% national average.
Recorded Violations and Out-of-Service Status
The public FMCSA record for ZST INC carries 31 recorded violations, and the most recent inspection on file is dated August 13, 2026. Across 24 recorded inspections, the record carries 2 driver out-of-service violations and 1 vehicle out-of-service violation.
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.
What a 97/100 Carrier Intelligence Score Means
The Carrier Intelligence Score is FileFlo's own summary of three public FMCSA components for ZST INC: the safety rating, the inspection pass rate and the out-of-service rate against the national average. It is not an FMCSA score, and FMCSA does not use it to choose carriers for an investigation. 97 out of 100 falls in FileFlo's Low Risk band.
Pennsylvania Trucking Compliance: KINZERS Area Carriers
ZST INC falls under the Eastern Service Center for FMCSA field-office oversight (region code 03). Service-center territory drives which FMCSA Investigator team would conduct a new-entrant audit or compliance review if one is triggered for this carrier.
Authority Type, Hazmat Status, and Operating Profile
ZST INC is classified by FMCSA as an interstate carrier.
The carrier holds an Authorized For Hire classification, meaning it transports cargo or passengers for compensation under FMCSA operating authority and is subject to MC-number requirements at 49 CFR Part 365.
Business organization type: Corporation.
ZST INC 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, 9 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: 568,833 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.
Fleet Composition and Driver Profile
Owned equipment per the FMCSA Census filing: 7 tractors, 10 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 9 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: Sheds Gazebos. Cargo type drives which BASIC categories the carrier is monitored under (Hazmat Compliance applies only to HM-flagged carriers; Cargo-Related Crash applies broadly).
FMCSA Crash History
The FMCSA Motor Carrier Management Information System (MCMIS) crash dataset records 13 crash events involving ZST INC in the available reporting window. Of these, 1 involved a fatality, 7 involved a reported injury, and 11 resulted in a tow-away. 13 events meet the federal-recordable threshold under 49 CFR 390.5 (fatality, injury treated away from the scene, OR tow-away of any vehicle).
Most recent recorded event: SR 2, JERUSALEM (TOWNSHIP OF), OH on January 12, 2026.
ZST INC's Inspection Fingerprint: Geographic Pattern and Trend
Inspections cluster geographically across Ohio (4), Indiana (3), Iowa (3). The concentration in Ohio is consistent with the carrier's primary lanes and tends to correlate with which state DOT inspector teams ZST INC's drivers encounter most often at roadside checkpoints.
How ZST INC Compares to the National Average
Across the 24 recorded inspections, ZST INC's 4.2% vehicle out-of-service rate sits well below the FMCSA 2024 national average of 20.72%. The 4.2% driver out-of-service rate sits slightly below the 2024 national average of 5.51%.
