Methodology
Each point is the percentage of that month's roadside inspections conducted at Level 1 — a full vehicle and driver inspection — as opposed to the lighter Level 2 (walk-around) and Level 3 (driver-only) inspections. Inspections with no recorded level are excluded from the denominator. Source: FMCSA roadside inspection records from data.transportation.gov, refreshed daily.
