Hours of service (HOS) & ELDs
Hours-of-service rules are the federal fatigue limits for commercial drivers. The core property-carrier limits: up to 11 hours of driving after 10 consecutive hours off duty, all driving inside a 14-hour on-duty window, a 30-minute break after 8 cumulative hours of driving, and no driving after 60 hours on duty in 7 days or 70 in 8. Since the electronic logging device (ELD) mandate took full effect, most drivers' hours are recorded by the ELD rather than a paper logbook.
Where HOS shows up in the public record
Individual driver logs are not public. What is public is the violation trail: hours-of-service findings from roadside inspections, which feed the Hours-of-Service Compliance BASIC. A carrier whose drivers keep getting written up for HOS violations is showing a pattern no insurance certificate reveals.
How fleetfax reads it
fleetfax rolls up each carrier's HOS-category violations from the inspection record and benchmarks them against carriers with a similar amount of inspection activity, labeled as fleetfax peer estimates (official FMCSA percentiles are not public).
fleetfax reads public FMCSA data and is not affiliated with FMCSA or the U.S. Department of Transportation. This page explains terminology; it is not legal advice.
