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
A high share of violations are occurring in Middlesex County, MA
Medium impact11 of 11 violations in the last 12 months (100%) came from inspections in Middlesex County, MA. 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 Middlesex County, MA to spot recurring issues
- Brief drivers running that lane; consider rerouting around the toughest enforcement corridors where practical
Unsafe Driving needs attention

live · FMCSA MCMISEvery inspection and crash on record — hover a point for the summary, click for full detail (codes, severity, CSA points).
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.
