ELD & hours-of-service
6 hours-of-service / ELD violations on record · most recent Mar 26, 2026. FMCSA does not publish the ELD device brand; these are the carrier's logging-compliance signals.
Trending worse — 100% of ELD violations are in the last 24 months. Falsified-log violations are a serious integrity flag.
