The four supported BASICs require readable snapshot data and a computed measure to list violations or open a report. Estimated positions also require sufficient carrier data and passed publication checks; calibration failure can withhold a position or retain a dated previous estimate. Controlled Substances/Alcohol is subject to these checks too. Missing carrier data, no relevant inspections, no applicable violations and an unavailable calculation are different states. An unavailable result is not a zero or a claim that there are no violations. HM Compliance and Crash Indicator have no report calculation in this product.

Unsafe Driving’s SMS denominator is average power units × utilization factor, which depends on vehicle miles traveled (VMT) and carrier segment (Equation 3–1). Our product lacks the historical power-unit inputs needed to reconstruct and validate that full calculation. It calculates numerator points internally only; Unsafe Driving records, measure and estimated position are not offered in this lookup.

Severity weight is an input. Weighted numerator contribution accounts for time weighting and the inspection cap. The marginal change in a named BASIC measure also depends on its denominator. An estimated percentile compares carriers within a safety event group and must be read with its range. Do not add points across BASICs. SMS calculations are separate from an official safety rating. This is our estimate from public FMCSA data, not an official FMCSA percentile.
