Electronic Logging Devices (ELDs) have been mandatory for most commercial motor vehicle drivers since 2019, but compliance remains one of the most common sources of violations at roadside inspections. In 2026, the FMCSA has introduced updated certification requirements and expanded the list of approved devices, making it more important than ever to understand the rules.
An ELD automatically records a driver's driving time, linking directly to the engine to capture data about whether the vehicle is moving. It replaces paper logbooks for most drivers who are required to keep records of duty status (RODS). The device must meet strict technical specifications and be registered with the FMCSA.
Not every driver needs an ELD. Exemptions include drivers operating under short-haul exceptions, drivers of vehicles manufactured before model year 2000, and drivers who operate within 100 air miles of their home terminal and return each day. If you qualify for an exemption, document it clearly — inspectors will ask.
Common ELD violations include failing to transfer records to an inspector during a roadside check, incorrect login procedures, and improper use of the personal conveyance or yard move annotations. Each of these carries point values under the CSA system. Understanding how to properly annotate logs and transfer data is non-negotiable.
Carriers should ensure all drivers receive annual ELD training that covers not just how to use the device, but how to handle malfunctions. FMCSA regulations require drivers to revert to paper logs for up to 8 days if their ELD malfunctions, and they must carry blank paper log forms in the cab at all times.
