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.
Driver out-of-service rate exceeds the national average
High impactDriver OOS rate is 12.5% 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
False log / RODS violations are the leading contributor to Hours-of-Service Compliance
Medium impactEstimated Hours-of-Service Compliance percentile of 59% is close to the 65% intervention line — worth getting ahead of before it crosses.

- 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
Drugs / alcohol violations are the leading contributor to Controlled Substances/Alcohol
Low impactEstimated Controlled Substances/Alcohol percentile of 19% is under the 80% line. In decent shape, but here's what's driving it.

90-day safety improvement plan
What this carrier has struggled with most in the last 90 days — where to focus now.
- 395.8F1-HOSMHOS (Manner) - Driver's record of duty status not current to the time shown for last change of duty status. Date and Time:
- Log in and annotate the ELD correctly every day; fix edits promptly
- Plan trips around available hours — never falsify a log
- 392.2-SLLS2State/Local Laws - Speeding 6-10 miles per hour over the speed limit
- Coach speed and following distance — Unsafe Driving points are weighted heavily
- Hands off the phone; always belt up
- 391.41APCMedical (Certificate) - Operating a property-carrying vehicle without a valid medical certificate in possession or on file with the state drivers licensing agency
- Track CDL, medical card, and endorsement expirations ahead of time
- Keep the DQ file complete and the medical card on the driver

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.
