Carrier Intelligence Score

58/100 Elevated Risk

Category	Score	Max
Safety Rating	30	30
Inspection Pass Rate	5	20
Out-of-Service Rate (vs FMCSA national avg)	3	15
CSA BASIC percentiles	Not measured	n/a

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.

FMCSA Safety Record & Inspection History

SIERRA TAHOE READY MIX INC has undergone 4 recorded DOT inspections. The vehicle out-of-service rate is 75.0%, 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 25%, above the national average of 5.51%. Common causes include hours-of-service violations, expired medical certificates, and CDL issues.

Recorded Violations and Out-of-Service Status

The public FMCSA record for SIERRA TAHOE READY MIX INC carries 9 recorded violations, and the most recent inspection on file is dated August 19, 2026. Across 4 recorded inspections, the record carries 1 driver out-of-service violation and 7 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.

What a 58/100 Carrier Intelligence Score Means

The Carrier Intelligence Score is FileFlo's own summary of three public FMCSA components for SIERRA TAHOE READY MIX 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. 58 out of 100 falls in FileFlo's Elevated Risk band.

California Trucking Compliance: SOUTH LAKE TAHOE Area Carriers

Motor carriers operating in California must comply with both federal FMCSA regulations and state-specific transportation requirements. The SOUTH LAKE TAHOE, CA corridor is monitored by FMCSA field offices and state highway patrol units conducting roadside inspections. Carriers based in SOUTH LAKE TAHOE should ensure driver qualification files, vehicle inspection reports, and hours-of-service records are current and audit-ready at all times.

SIERRA TAHOE READY MIX 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.

Authority Type, Hazmat Status, and Operating Profile

SIERRA TAHOE READY MIX INC is classified by FMCSA as an interstate carrier.

The carrier holds an Private Property;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.

SIERRA TAHOE READY MIX 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 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: 219,755 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: 9 straight trucks, 3 tractors, 6 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 13 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 3 crash events involving SIERRA TAHOE READY MIX INC in the available reporting window. Of these, 0 involved a fatality, 2 involved a reported injury, and 3 resulted in a tow-away. 3 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: US50 / TAMARACK, ZEPHYR COVE, NV on October 27, 2025.

How SIERRA TAHOE READY MIX INC Compares to the National Average

Across the 4 recorded inspections, SIERRA TAHOE READY MIX INC's 75.0% vehicle out-of-service rate sits substantially above the FMCSA 2024 national average of 20.72%. The 25.0% 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.
