What Is an ELD? Meaning, How It Works and Who Needs One (2026)

ELD means Electronic Logging Device. In trucking, the term usually means the whole system: the device in the truck, the driver app on a phone or tablet, and the back-office portal.

• The device connects to the engine (diagnostic port) and records engine hours, miles, location and driving status.
• The driver app shows duty status: Off Duty, Sleeper Berth, Driving, On Duty.
• During a roadside inspection the driver shows or transfers the ELD logs to the officer.
• Fleet owners review logs, violations and IFTA miles in a web portal.

Under FMCSA rules, most drivers who must keep Records of Duty Status need an ELD. Separately, many brokers and load boards now ask for ELD tracking before they give a load, even for vans and small trucks that aren't legally required to have one.

• Drivers using the short-haul exemption (no log needed).
• Drivers who keep paper logs no more than 8 days in any 30-day period.
• Driveaway-towaway operations.
• Vehicles with engines older than model year 2000.
• Always confirm your situation on FMCSA's website.

Paper logs are filled in by hand and are easier to get wrong. ELD logs record driving automatically, which cuts form-and-manner violations and makes IFTA mileage simpler.
