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.
SANDRA LUZ SALAZAR ESTRADA is a small carrier operating out of NOGALES, SO with USDOT number 2403664. The company operates 3 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, SANDRA LUZ SALAZAR ESTRADA has a FileFlo Carrier Intelligence Score (CIS) of 69/100, classified as Moderate Risk. This score reflects limited public data — a full roadside-inspection history was not available at page generation, so the inspection and out-of-service components use conservative neutral values.
Limited inspection data is currently available for SANDRA LUZ SALAZAR ESTRADA. Carriers with fewer recorded inspections may face increased scrutiny during roadside encounters, as FMCSA inspectors may flag them for more thorough reviews.
A CIS score of 69 places SANDRA LUZ SALAZAR ESTRADA in the Moderate Risk category. While not in immediate danger of targeted enforcement, there are areas for improvement. Common issues at this level include inconsistent driver qualification file maintenance, lapsed vehicle inspection schedules, or minor CSA BASIC score creep.
Motor carriers operating in SO must comply with both federal FMCSA regulations and state-specific transportation requirements. The NOGALES, SO corridor is monitored by FMCSA field offices and state highway patrol units conducting roadside inspections. Carriers based in NOGALES should ensure driver qualification files, vehicle inspection reports, and hours-of-service records are current and audit-ready at all times.
FileFlo helps SO 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.
SANDRA LUZ SALAZAR ESTRADA 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.
SANDRA LUZ SALAZAR ESTRADA 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 within 100 miles (short-haul, 3 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: 8,950 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: 2 tractors. 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 3 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.
SANDRA LUZ SALAZAR ESTRADA operates as a micro-fleet (1-5 power units) — roughly 90% of registered interstate carriers fall in this band, per the most recent FMCSA Pocket Guide carrier-population distribution. Fleet-size band drives which compliance burdens are most material: micro-fleet operators most often cite driver qualification file maintenance and ELD compliance as their top time burdens; mid-size fleets shift toward maintenance-record retention and DOT audit preparation; large fleets focus on third-party drug-test program administration and corporate-level CSA percentile management.
This profile shows no recorded DOT inspections in the available reporting window. The 2024 FMCSA inspection-rate baseline runs ~3 inspections per power-unit per year for interstate carriers; carriers with materially lower rates either operate primarily within a 150-air-mile radius (lower exposure to roadside inspections) OR are recently registered and have not yet been encountered by an inspection team. SANDRA LUZ SALAZAR ESTRADA's 3-power-unit fleet would, at the national rate, see ~9 inspections per year.
