ELD

Definition

ELD - Electronic Logging Device - is the in-cab device that automatically records driver hours-of-service data under 49 CFR Part 395 subpart B. Required for most interstate CDL drivers since December 2017. The ELD must be on the FMCSA Registered ELD list, must integrate with the engine control module, and must produce a standard data file output that roadside inspectors can transfer for review. Short-haul exemptions exist for drivers operating within 150 air-miles and returning to the work-reporting location each day. Pre-2000 model-year vehicles may use paper logs. ELD violations are common at roadside inspections and feed the HOS BASIC.
