ELD Compliance: The Rules, the Exemptions, and the Headaches

The ELD mandate has been in full effect since December 2019, and at this point, there's no excuse for not being compliant. But "having an ELD plugged in" and "being ELD compliant" are two very different things. Let's talk about what actually matters.

Who Must Use an ELD?

Any driver required to keep RODS under Part 395 must use an ELD. That covers most CMV drivers in interstate commerce.

Exemptions exist for:

• Short-haul drivers within 150 air-miles who return to their work reporting location daily
• Drivers of vehicles manufactured before 2000 (no engine ECM (Engine Control Module — the truck's onboard computer that provides data to the ELD) to connect to)
• Drivers operating under the timecard exception (non-CDL, short-haul)
• Agricultural driveaway-towaway operations during specific periods

Choosing an ELD

Your ELD must be on FMCSA's registered devices list. Being on the list does NOT mean FMCSA certified or tested the device — it just means the manufacturer self-certified compliance. Important distinction.

Look for:

• Reliable Bluetooth or hardwired connection to the engine ECM
• Ability to transfer data via web service and email (required for roadside inspections)
• Driver-friendly interface — if your drivers can't use it, they won't use it correctly
• Good customer support — when the ELD glitches at 2 AM in Montana, you need someone to call

Common Compliance Issues

Unidentified Driving Events

When the truck moves but no driver is logged in, it creates an unidentified driving event. A few of these is normal (mechanics moving trucks in the yard). A lot of them is a red flag that suggests drivers are disconnecting from the ELD. Carriers must review and assign unidentified driving events regularly — ideally within 24 hours.

ELD Malfunctions

If an ELD malfunctions, the driver must note it on the RODS, reconstruct the current day's logs on paper, and continue using paper logs until the ELD is repaired. The carrier has 8 days to fix or replace the ELD. After 8 days, an extension requires FMCSA approval in writing.

Data Transfer Failures

During a roadside inspection, officers request ELD data. If the web transfer and email both fail, the officer may direct the driver to produce a printout or display the data on screen. Failure to produce any data = treated as no RODS = out of service.

Training Your Drivers

Don't just hand a driver an ELD and say "figure it out." Train them on:

• How to log in and change duty status correctly
• How to annotate and edit logs (within allowable HOS (Hours of Service — the federal rules limiting how long a driver can be on duty and behind the wheel) rules)
• How to handle malfunction situations
• How to transfer data to an inspector
• What not to do (disconnecting, driving in yard-move mode on public roads)
