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.
ARIZONA PIPELINE COMPANY INC is a large fleet operating out of HESPERIA, California with USDOT number 349324. The company operates 449 power units and holds a current FMCSA safety rating of Satisfactory. Based on our analysis of federal safety data, ARIZONA PIPELINE COMPANY INC has a FileFlo Carrier Intelligence Score (CIS) of 39/100, classified as High Risk.
ARIZONA PIPELINE COMPANY INC has undergone 50 recorded DOT inspections. The vehicle out-of-service rate is 36.0%, 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. The driver out-of-service rate is 10%, above the national average of 5.51%. Common causes include hours-of-service violations, expired medical certificates, and CDL issues.
The public FMCSA record for ARIZONA PIPELINE COMPANY INC carries 84 recorded violations, and the most recent inspection on file is dated 20260912. Across 50 recorded inspections, the record carries 6 driver out-of-service violations and 26 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 39 places ARIZONA PIPELINE COMPANY INC in the High Risk category. This carrier faces significant compliance exposure and is at elevated risk for targeted FMCSA enforcement actions, including compliance reviews and potential out-of-service orders. Immediate corrective action is strongly recommended.
Motor carriers operating in California must comply with both federal FMCSA regulations and state-specific transportation requirements. The HESPERIA, CA corridor is monitored by FMCSA field offices and state highway patrol units conducting roadside inspections. Carriers based in HESPERIA should ensure driver qualification files, vehicle inspection reports, and hours-of-service records are current and audit-ready at all times.
ARIZONA PIPELINE COMPANY INC falls under the Western Service Center for FMCSA field-office oversight (region code 09). 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 California 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.
ARIZONA PIPELINE COMPANY 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.
ARIZONA PIPELINE COMPANY 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, 25 drivers); interstate within 100 miles (short-haul, 112 drivers); intrastate within 100 miles (628 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: 2,214,166 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: 439 straight trucks, 10 tractors, 495 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 230 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.
Intrastate driver count: 628. Intrastate drivers may be subject to state-specific CDL endorsement and hours-of-service variances depending on the state.
The FMCSA Motor Carrier Management Information System (MCMIS) crash dataset records 20 crash events involving ARIZONA PIPELINE COMPANY INC in the available reporting window. Of these, 1 involved a fatality, 3 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: mandan rd/30FT s kinai rd, APPLE VALLEY, CA on 20260805.
Inspections cluster geographically across California (42), Arizona (4), New Mexico (3). The concentration in California is consistent with the carrier's primary lanes and tends to correlate with which state DOT inspector teams ARIZONA PIPELINE COMPANY INC's drivers encounter most often at roadside checkpoints.
Across the 50 recorded inspections, ARIZONA PIPELINE COMPANY INC's 36.0% vehicle out-of-service rate sits substantially above the FMCSA 2024 national average of 20.72%. The 10.0% driver out-of-service rate sits substantially above 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.
