The ELD Mandate: Who Must Run One

8 min

49 CFR §395.8(a)(1)

A carrier operating commercial motor vehicles had to install an ELD and require its drivers to use it no later than 2017-12-18. Four narrow situations still allow a driver to keep the record manually instead — and only those four.

Who the rule reaches

The ELD requirement rides on the record-of-duty-status requirement. If a driver must keep a record of duty status, the record must come from an ELD unless one of the four exceptions applies. Drivers who qualify for the short-haul exception never have to keep a record of duty status in the first place, so the question of an ELD does not arise for them at all — which is why so many local operations run without one perfectly legally.

The exemption belongs to the day, not to the driver. A short-haul driver who goes beyond the radius or the time limit owes a record of duty status for that day, and the 8-day rule below is what decides whether it may be on paper.

The four exceptions

ExceptionTestCatch
Occasional loggingA record of duty status on no more than 8 days in any 30Counted on a rolling window, not per month
Driveaway-towawayThe vehicle being driven is the shipmentDoes not cover a tractor pulling a loaded trailer
Motor home / RV transportThe vehicle transported is a motor home or RV trailerNarrower than the driveaway exception above
Pre-2000 engineModel year before 2000 as shown in the VIN on the registrationThe VIN governs, not a glider kit's engine

The occasional-logging exception is the one small carriers actually use. It is also the one most often lost: a driver who logs on nine days inside a rolling 30 owes an ELD from that ninth day, and the paper logs behind them do not become illegal but the tenth day's does.

At roadside

An officer may ask for the record in one of two ways: a telematics transfer (web services or email) or a local transfer (USB or Bluetooth). A compliant device supports one method from each pair. If neither works, the driver must be able to show the display or a printout — which is why the mandate also requires the device's user manual, an instruction sheet for the transfer, an instruction sheet for malfunctions, and at least eight blank paper log sheets to be carried in the cab.

Those four items are a documents check, not a technology check, and they are among the most common ELD violations written at roadside. They cost nothing to fix and are worth checking before every trip that leaves the state.

A malfunctioning ELD does not end the day. The driver reconstructs the current day and the past 7 on paper, notifies the carrier in writing within 24 hours, and the carrier has 8 days to repair or replace the device.

Choosing a device

Self-certification is the trap. FMCSA does not approve ELDs; vendors certify their own and are listed on the agency's register until they are removed. Devices have been removed, and a carrier running a revoked device has a fixed window to replace it. Check the register before you buy and again at renewal — the check takes a minute and the alternative is re-fitting a fleet.

Feature comparison for the devices owner-operators actually buy is on the ELD comparison. What the device records still has to obey the 11/14/70 limits — no device makes an hour legal that was not.
