ELD Mandate
The ELD Mandate is the FMCSA rule requiring most interstate truck and bus drivers who must keep records of duty status to record their hours of service with a registered electronic logging device.
What it requires
Published December 16, 2015 under a MAP-21 directive, the rule required ELDs from December 18, 2017, with older automatic onboard recording devices allowed until December 16, 2019. It covers drivers who must keep logs more than 8 days in any 30-day period, with exceptions for short-haul drivers, driveaway operations and engines older than model year 2000. Devices must appear on FMCSA's registry, and a revoked device counts as no ELD. A rule effective July 22, 2026 dropped the in-cab user manual requirement.
Why it matters
The ELD Mandate made hours-of-service limits enforceable to the minute, which tightened truck capacity and raised the cost of waiting at warehouses. Drivers cannot absorb long dock delays, so detention at a fulfillment center directly cuts the miles they can drive. For example, if a driver waits three hours to unload at a 3PL dock, those hours count against the 14-hour duty window and may force a rest break before the next load, so the carrier bills detention or declines future loads. Efficient appointment scheduling and dock management are now part of carrier relations.
