Safety trends & next-run projection
Where each BASIC sits today, how it ranks against peers, and where it’s heading at the next monthly SMS run.
FMCSA keeps the Crash Indicator percentile private, and its measure needs a power-unit history public data doesn’t expose — so it can’t be estimated yet. VioCodes now records power units monthly, so a calibrated Crash estimate should light up over time. These are the public crash facts (all state-reportable crashes count, regardless of fault).
“Projected” estimates the next monthly SMS run from inspections on record now. FMCSA marks the BASIC percentile itself “Not Public,” so the percentile shown is a VioCodes estimate of how the carrier ranks against its peers, presented as a likely range (shaded on the gauge) and calibrated against real carriers. Crash Indicator has no public estimate — FMCSA keeps its measures fully private. Estimates, not official FMCSA figures. Not affiliated with FMCSA.
Recommendations
What’s driving each score, what to do about it, and where it could go.
False log / RODS violations are the leading contributor to Hours-of-Service Compliance
High impactEstimated Hours-of-Service Compliance percentile of 98% is at/over the 65% intervention line. Carriers with a BASIC in alert are prioritized for enforcement (warning letters, audits) and inspected more often — which tends to generate still more violations.

- 395.22H1Driver failing to maintain ELD user's manual1× · 0%
- Audit ELD edits and duty-status annotations weekly; a false log is a high-severity, high-visibility violation
- Retrain on correct logging and never letting a load pressure a driver into a false entry
- Prioritize the out-of-service items — they carry the heaviest weight
Brakes violations are the leading contributor to Vehicle Maintenance
High impactEstimated Vehicle Maintenance percentile of 100% is at/over the 80% intervention line. Carriers with a BASIC in alert are prioritized for enforcement (warning letters, audits) and inspected more often — which tends to generate still more violations.

- Check brake adjustment and listen for air leaks every pre-trip; put brakes on the PM schedule
- Fix air-loss and warning-light faults before dispatch — don’t “drive it in”
- Prioritize the out-of-service items — they carry the heaviest weight
Vehicle and driver out-of-service rate exceeds the national average
High impactVehicle OOS rate is 43.5% vs the 22% national average. Driver OOS rate is 25.9% vs the 6.7% national average. Carriers above the national OOS average draw more enforcement attention (audits, roadside stops) and can see higher insurance premiums.
- Review recent inspections with out-of-service violations and fix the root causes with equipment and drivers
- Run a preventative-maintenance program; periodically inspect tires, brakes and lights
- Reinforce thorough pre-trip and post-trip inspections; retrain where needed
Phone / texting violations are the leading contributor to Unsafe Driving
Medium impactEstimated Unsafe Driving percentile of 61% is close to the 65% intervention line — worth getting ahead of before it crosses.
- 392.2-SLLCPState/Local Laws - Operate a CMV while using a cellular phone1× · 48%
- 392.2-SLLTCDState/Local Laws - Failed to obey a traffic control device - Permanent or Temporary - e.g., safety official, signal, sign, light, lane marking, other1× · 24%
- Hands-off-the-phone policy with real consequences; provide a mount and a do-not-disturb setup
A high share of violations are occurring in TX
Medium impact60 of 133 violations in the last 12 months (45%) came from inspections in TX. That can mean tougher enforcement there or simply more of your miles run through it — either way it's worth a look.
- Review the inspections from TX to spot recurring issues
- Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical
Drugs / alcohol violations are the leading contributor to Controlled Substances/Alcohol
Low impactEstimated Controlled Substances/Alcohol percentile of 31% is under the 80% line. In decent shape, but here's what's driving it.
- 392.15Driver Prohibited from Performing Safety Sensitive Functions per 382.501(a) in the Drug and Alcohol Clearinghouse1× · 100%
- Reinforce the testing program and zero-tolerance policy
- Prioritize the out-of-service items — they carry the heaviest weight

Connections
carrier graphThis carrier shares VINs or officers with 13 other carriers — review the connections below as part of your vetting.
Shared VINs come from FMCSA roadside-inspection records — a vehicle inspected under more than one carrier, often a fleet transfer or trailer interchange. Other links come from the FMCSA census. Shared identifiers are common and often legitimate — treat these as leads to investigate, not proof of wrongdoing.
