DOT DOT Electronic Logging Device (ELD) Requirements 5 — Questions and Answers
Question 1: A driver uses an ELD and also a paper logbook on the same day 'just to be safe.' What violation does this create?
- No violation — redundant records are encouraged for accuracy
- Failure to use an ELD as the sole method of record-keeping (Correct answer)
- An automatic falsification-of-records violation
- A vehicle out-of-service condition
Correct answer: Failure to use an ELD as the sole method of record-keeping
Once subject to the ELD mandate, drivers must use the ELD as their sole RODS method; maintaining simultaneous paper logs is prohibited.
Question 2: What is the minimum number of hours that must elapse, after the ELD mandate became fully effective, before a registered ELD can be de-listed from the FMCSA registry without a phase-out period?
- There is no minimum — FMCSA can de-list an ELD immediately for non-compliance (Correct answer)
- 90 days with carrier notification
- 6 months with an automatic grandfather clause
- 1 year grace period is mandatory
Correct answer: There is no minimum — FMCSA can de-list an ELD immediately for non-compliance
FMCSA may immediately de-list a non-compliant ELD from the registry; there is no mandatory grace period once non-compliance is identified.
Question 3: During a roadside inspection, which statement about an ELD's engine synchronization requirement is correct?
- The ELD must synchronize with the engine ECM to record engine power-on, motion status, miles, and engine hours (Correct answer)
- Synchronization with the ECM is optional if GPS tracking is active
- Only miles driven need to come from the ECM; the rest can be estimated
- ECM synchronization is required only for vehicles manufactured after 2020
Correct answer: The ELD must synchronize with the engine ECM to record engine power-on, motion status, miles, and engine hours
ELDs must interface with the vehicle's engine ECM to automatically record engine power status, vehicle motion, miles driven, and engine hours.
Question 4: A carrier instructs drivers to set duty status to 'On-Duty Not Driving' during fuel stops longer than 15 minutes. An inspector finds evidence that drivers are routinely recording fuel stops as 'Off-Duty.' What is the primary compliance issue?
- Incorrect duty status entry leading to potential falsification of records (Correct answer)
- Using the wrong ELD mode for non-driving activity
- Failing to annotate the ELD with a location update
- No issue — fuel stops under 30 minutes are automatically Off-Duty
Correct answer: Incorrect duty status entry leading to potential falsification of records
Fuel stops where the driver is working or waiting under carrier control are On-Duty time; recording them as Off-Duty constitutes a falsification violation.
Question 5: An ELD provider claims its device is compliant because it passed a third-party audit. What does the FMCSA ELD rule actually require for certification?
- FMCSA direct certification approval for each device
- Self-certification by the ELD provider with registration in the FMCSA ELD registry (Correct answer)
- Certification by one of three FMCSA-approved testing labs
- Annual re-certification by a DOT-licensed inspector
Correct answer: Self-certification by the ELD provider with registration in the FMCSA ELD registry
The ELD rule uses a self-certification model: providers test their own devices, certify compliance, and register the device on the FMCSA ELD registry.
Question 6: Under what condition may a driver annotate an ELD entry without the carrier's co-signature?
- Never — all annotations require carrier confirmation
- At any time — drivers may annotate their own records and the annotation stands unless the carrier edits it (Correct answer)
- Only during a roadside inspection at an inspector's request
- Only to correct a location entry, not a duty status entry
Correct answer: At any time — drivers may annotate their own records and the annotation stands unless the carrier edits it
Drivers may add annotations to their own ELD records at any time; carrier counter-signature is not required for driver-initiated annotations.
Question 7: What is the maximum allowable time gap between an ELD's automatic location recording during on-duty driving?
- Every 5 minutes (Correct answer)
- Every 60 minutes
- Every 30 minutes
- Every 15 minutes
Correct answer: Every 5 minutes
ELDs must automatically record the vehicle's location at least every 60 minutes during on-duty driving, but the position accuracy must be within 1 mile — some interpret the sampling as every 5 minutes for accuracy; the rule requires recording at each change-of-duty-status and at least every 60 minutes.
