Electronic Logging Device
What is electronic logging device? An electronic logging device (ELD) is a hardware-software combo that automatically records driver hours of service and engine activity, mandated by FMCSA since 2017.
Full definition
The ELD mandate took effect in December 2017 and is now the operational baseline of US trucking. The device must be FMCSA-registered, connected to the engine ECM, and capture driving time, on-duty time, and location every 60 minutes while driving.
ELDs feed roadside inspections, IFTA mileage reports, and CSA scoring. Tampering or driver-coercion violations are major FMCSA infractions that affect carrier ratings and insurance pricing.
ELDs cost roughly $200-$500 per truck plus monthly service ($20-$50/month). Many fuel cards and factoring providers bundle preferred-pricing ELD relationships for cash flow customers.
