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 77% is at/over the 60% 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.
- 395.8A1-HOSPHOS (Property) - Failing to have a record of duty status using the method prescribed7× · 43%
- 395.8E-HOSPDHOS (Property) - No driver may make a false report in connection with a duty status. Explain7× · 42%

- 395.24D-ELDPTHOS (ELD) - On request by an authorized safety official, a driver must produce and transfer from an ELD the driver's hours of service records in accordance with t1× · 4%
- 395.24C2III-ELDSDNHOS (ELD) - Driver failing to manually input or verify shipping document number.1× · 0%
- 395.22H1-ELDNUMHOS (ELD) - In-Vehicle Information - No user's manual for the driver describing how to operate the ELD. (May be electronic)1× · 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
Lighting / lamps violations are the leading contributor to Vehicle Maintenance
High impactEstimated Vehicle Maintenance percentile of 100% is at/over the 75% 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.

- Walk the lights every pre-trip and carry spare bulbs/fuses; clean lenses and check the trailer plug

Vehicle and driver out-of-service rate exceeds the national average
High impactVehicle OOS rate is 61.9% vs the 22% national average. Driver OOS rate is 13.2% 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
A high share of violations are occurring in MT
Medium impact63 of 159 violations in the last 12 months (40%) came from inspections in MT. 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 MT to spot recurring issues
- Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical
Speeding violations are the leading contributor to Unsafe Driving
Low impactEstimated Unsafe Driving percentile of 12% is under the 60% line. In decent shape, but here's what's driving it.
- 392.2-SLLS2State/Local Laws - Speeding 6-10 miles per hour over the speed limit2× · 60%
- 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× · 25%
- 392.2-SLLLRState/Local Laws - Lane restriction violation1× · 15%
- Coach the drivers with speeding violations directly — Unsafe Driving points are weighted heavily
- Set and enforce a governed road speed; review telematics/dashcam speed events weekly
Controlled Substances/Alcohol needs attention
Low impactEstimated Controlled Substances/Alcohol percentile of 0% is under the 75% line. In decent shape, but here's what's driving it.
- Review recent inspections with violations in this BASIC and take remedial action with drivers/equipment

CSA points = violation severity weight × FMCSA time weight (3× in the last 6 months, 2× at 6–12, 1× at 12–24). Points are spread within each state — FMCSA records the inspection state, not an exact location. Source: FMCSA MCMIS.

Connections
carrier graphThis carrier shares VINs, addresses, phone numbers or emails with 8 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.
