54/100 Elevated Risk
| Category | Score | Max |
|---|---|---|
| Safety Rating | 22 | 30 |
| Inspection Pass Rate | 10 | 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.
ROCKLYNN CONSTRUCTION LLC: CLIFTON HTS, Pennsylvania Trucking Company
ROCKLYNN CONSTRUCTION LLC is a small fleet operating out of CLIFTON HTS, Pennsylvania with USDOT number 3639752. The company operates 12 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, ROCKLYNN CONSTRUCTION LLC has a FileFlo Carrier Intelligence Score (CIS) of 54/100, classified as Elevated Risk.
FMCSA Safety Record & Inspection History
ROCKLYNN CONSTRUCTION LLC has undergone 10 recorded DOT inspections. The vehicle out-of-service rate is 40.0%, 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 20%, 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 ROCKLYNN CONSTRUCTION LLC carries 60 recorded violations, and the most recent inspection on file is dated 20261007. Across 10 recorded inspections, the record carries 3 driver out-of-service violations and 12 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 54/100 Carrier Intelligence Score Means
A CIS score of 54 places ROCKLYNN CONSTRUCTION LLC in the Elevated Risk category. Carriers at this level are more likely to be selected for compliance reviews and roadside inspections. Immediate attention to driver qualification files, hours-of-service records, and vehicle maintenance logs is recommended.
Pennsylvania Trucking Compliance: CLIFTON HTS Area Carriers
Motor carriers operating in Pennsylvania must comply with both federal FMCSA regulations and state-specific transportation requirements. The CLIFTON HTS, PA corridor is monitored by FMCSA field offices and state highway patrol units conducting roadside inspections. Carriers based in CLIFTON HTS should ensure driver qualification files, vehicle inspection reports, and hours-of-service records are current and audit-ready at all times.
FileFlo helps Pennsylvania 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
ROCKLYNN CONSTRUCTION LLC 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.
ROCKLYNN CONSTRUCTION LLC 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, 12 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: 140,000 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, 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 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 1 crash event involving ROCKLYNN CONSTRUCTION LLC in the available reporting window. Of these, 0 involved a fatality, 0 involved a reported injury, and 1 resulted in a tow-away. 1 event meets 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: ROUTE 2010 E, ALDAN BOROUGH, PA on 20260125.
How ROCKLYNN CONSTRUCTION LLC Compares to the National Average
Across the 10 recorded inspections, ROCKLYNN CONSTRUCTION LLC's 40.0% vehicle out-of-service rate sits substantially above the FMCSA 2024 national average of 20.72%. The 20.0% 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.
