PIERSOL CONSTRUCTION INC: AIRWAY HEIGHTS, Washington Trucking Company
PIERSOL CONSTRUCTION INC is a mid-size fleet operating out of AIRWAY HEIGHTS, Washington with USDOT number 542952. The company operates 22 power units and has no published FMCSA safety rating (most active carriers are unrated unless they have undergone a compliance review). Based on our analysis of federal safety data, PIERSOL CONSTRUCTION INC has a FileFlo Carrier Intelligence Score (CIS) of 63/100, classified as Moderate Risk.
FMCSA Safety Record & Inspection History
PIERSOL CONSTRUCTION INC has undergone 3 recorded DOT inspections. The vehicle out-of-service rate is 33.3%, which is above the national average of 20.72%. This elevated rate indicates potential maintenance or pre-trip inspection deficiencies that could lead to roadside violations.
Recorded Violations and Out-of-Service Status
The public FMCSA record for PIERSOL CONSTRUCTION INC carries 5 recorded violations, and the most recent inspection on file is dated May 11, 2026. Across 3 recorded inspections, the record carries 0 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 63/100 Carrier Intelligence Score Means
The Carrier Intelligence Score is FileFlo's own summary of three public FMCSA components for PIERSOL CONSTRUCTION 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. 63 out of 100 falls in FileFlo's Moderate Risk band.
Washington Trucking Compliance: AIRWAY HEIGHTS Area Carriers
PIERSOL CONSTRUCTION INC falls under the Western Service Center for FMCSA field-office oversight (region code 10). 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
PIERSOL CONSTRUCTION INC 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.
PIERSOL CONSTRUCTION INC is flagged in FMCSA Census as a hazardous materials carrier (HM indicator: Y). Hazmat carriers are subject to additional regulations under 49 CFR Subchapter C, including HM-126 reporting, HM-232 security planning, and the Hazmat Cargo Tank Annual Inspection requirement (49 CFR 180.407). Hazmat violations carry their own, higher penalty schedule, separate from the general FMCSA schedule.
Operational range per MCS-150 filing: interstate within 100 miles (short-haul, 13 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: 210,000 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: 12 straight trucks, 9 tractors, 13 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 12 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.
FMCSA Crash History
The FMCSA Motor Carrier Management Information System (MCMIS) crash dataset records 7 crash events involving PIERSOL CONSTRUCTION INC in the available reporting window. Of these, 0 involved a fatality, 0 involved a reported injury, and 7 resulted in a tow-away. 7 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: I-90*272.10, SPOKANE, WA on December 9, 2024.
How PIERSOL CONSTRUCTION INC Compares to the National Average
Across the 3 recorded inspections, PIERSOL CONSTRUCTION INC's 33.3% vehicle out-of-service rate sits substantially above 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%.
