SafeNY Underinsured Flag (statistical signal)

Insurance posture flagged below statistical reference range.

Policy limit on file: $1M. This carrier's filed BIPD coverage is below the statistical reference range for its domicile state-tier. The flag is a categorical statistical signal derived from SNRS factor decomposition (see /methodology#snrs); it is not a verdict prediction or a recovery recommendation.

Night-driving crash pattern

The SafeNY Night-Driving Pattern: of 16 documented crashes in the past 5 years, 10 occurred in dark conditions (no street lighting, partial lighting, or unknown roadway lighting). That's 62.5% of this carrier's crashes vs the FMCSA dataset baseline of 25.7%.

62.5% dark-condition share vs 25.7% national baseline. Statistically significant elevation (p<0.001). Pattern consistent with night-shift operations or potential Hours-of-Service scheduling concerns (49 CFR § 395).

Statistically elevated dark-condition crash concentration

Method: One-sample binomial test against 25.7% baseline (FMCSA SMS Crash File 2026-04 Snapshot, n≈259k national records). p < 0.001. Dark-condition driving is regulated under 49 CFR § 392.14 (hazardous conditions); federal Hours-of-Service rules at 49 CFR § 395 limit consecutive driving hours and overlap with night-driving fatigue management.

Risk decomposition

Five-factor breakdown of the SafeNY SNRS for this carrier, used to explain the composite score.

Driven primarily by negligence (driver behavior — HOS + Unsafe Driving + Controlled Substances) at 5.1/10, below the mid- cohort median of 4.5.

Method: how this carrier's SafeNY SNRS was computed(expand for carrier-specific walkthrough)

The five factors below come from Baltimore Tank Lines LLC's actual FMCSA records. Each factor is a 0–10 score; the composition produces a 0–10 SNRS smoothed against the prior month's value (α = 0.40). The Bayesian step below leaves exposure_M-PUD symbolic; the closed-form denominator and a worked example are on /methodology#shrinkage.

Step 1 — Bayesian-shrunk crash rate

This carrier has 16 documented crashes in the past 5 years (0 fatal). The cohort prior (mean fatal rate for similar-sized fleets) is 0.304 events per million power-unit-days; after Bayesian shrinkage with prior strength w₀ = 10, this carrier's adjusted rate is 0.298.

r^shrunk  =  10⋅0.304  +  1610  +  exposureM-PUD  =  0.298\hat{r}_{\text{shrunk}} \;=\; \frac{10 \cdot 0.304 \;+\; 16}{10 \;+\; \text{exposure}_{\text{M-PUD}}} \;=\; 0.298

Step 2 — Five-factor SNRSraw composition (B-method)

SNRSraw  =  0.60⋅max⁡(C,N,M)  +  0.30⋅median⁡(C,N,M,D)  +  0.10⋅SSNRS_{raw} \;=\; 0.60 \cdot \max(C, N, M) \;+\; 0.30 \cdot \operatorname{median}(C, N, M, D) \;+\; 0.10 \cdot S
  =  0.60⋅max⁡(5.0,5.1,2.4)  +  0.30⋅median⁡(5.0,5.1,2.4,1.9)  +  0.10⋅0.6  =  4.3\quad\;=\; 0.60 \cdot \max(5.0, 5.1, 2.4) \;+\; 0.30 \cdot \operatorname{median}(5.0, 5.1, 2.4, 1.9) \;+\; 0.10 \cdot 0.6 \;=\; 4.3

C Crash 5.0 · N Negligence 5.1 · M Mechanical 2.4 · D Driver 1.9 · S Stability 0.6

Step 3 — EMA smoothing against last month's value

SNRS  =  α⋅SNRSraw  +  (1−α)⋅SNRSprev,α=0.40SNRS \;=\; \alpha \cdot SNRS_{raw} \;+\; (1-\alpha) \cdot SNRS_{\text{prev}}, \quad \alpha = 0.40

For Baltimore Tank Lines LLC: SNRSraw = 4.3 → smoothed SNRS = 4.3. (Prior month's smoothed value is the EMA weight; the first month of data uses raw without smoothing.)
