DOT DOT Electronic Logging Device (ELD) Requirements 4 — Questions and Answers
Question 1: Under the ELD rule, what is the maximum number of minutes an ELD can be in 'unassigned driving time' before a carrier must investigate?
- 30 minutes
- 60 minutes
- No specific time limit — unassigned time must be reviewed at each upload cycle (Correct answer)
- 24 hours
Correct answer: No specific time limit — unassigned time must be reviewed at each upload cycle
There is no specific minute threshold; carriers must review and assign unassigned driving time during the regular data transfer cycle.
Question 2: A driver's ELD malfunctions. Which document must the driver keep on hand to reconstruct their hours of service?
- A blank logbook provided by the carrier
- Paper logs (RODS) for the current 24-hour period plus the previous 7 consecutive days (Correct answer)
- Only today's paper log
- A printed ELD data summary for the current trip
Correct answer: Paper logs (RODS) for the current 24-hour period plus the previous 7 consecutive days
When an ELD malfunctions, drivers must keep paper logs for the current day plus the previous 7 days until the device is repaired or replaced.
Question 3: Which of the following ELD output formats is NOT required to be supported for roadside inspection data transfer?
- Telematics web service transfer
- Local Bluetooth transfer
- Email attachment transfer (Correct answer)
- USB 2.0 transfer
Correct answer: Email attachment transfer
The ELD rule requires local (Bluetooth and USB 2.0) and telematics (web service and email to FMCSA) transfer methods, but email attachment is not a standalone required method.
Question 4: An inspector notices a driver's ELD display shows 'ELD Malfunction' with indicator code 'P'. What does code 'P' signify?
- Power compliance malfunction
- Positioning compliance malfunction (Correct answer)
- Printing malfunction
- Protocol sync error
Correct answer: Positioning compliance malfunction
Malfunction code 'P' indicates a positioning compliance malfunction, meaning the ELD cannot accurately determine the vehicle's location.
Question 5: For a commercial motor vehicle operating under the short-haul exemption (100 air-mile radius), when does the ELD requirement NOT apply?
- When the driver returns to the home terminal within 12 hours and does not use the sleeper berth (Correct answer)
- Whenever the driver stays within the state
- When the carrier has fewer than 10 trucks
- When the trip is under 50 miles
Correct answer: When the driver returns to the home terminal within 12 hours and does not use the sleeper berth
Drivers qualify for the short-haul ELD exemption if they return to the home terminal within 12 consecutive hours and do not use a sleeper berth.
Question 6: Which personnel are permitted to edit a driver's ELD records according to FMCSA regulations?
- Only the carrier's safety department
- The driver and authorized carrier personnel, but the original data must be retained (Correct answer)
- The ELD provider's technical support staff
- Only an FMCSA-certified inspector
Correct answer: The driver and authorized carrier personnel, but the original data must be retained
Both the driver and authorized carrier personnel may edit ELD records, but the original unedited record must always be preserved.
Question 7: During a Level 3 inspection focusing on ELD compliance, an inspector finds the ELD is certified but the driver cannot demonstrate how to display records on screen. What is the appropriate enforcement action?
- Immediately place the vehicle out of service
- Issue a driver violation for failing to provide records in an inspectable format (Correct answer)
- Issue a citation for the carrier only, not the driver
- No action — the carrier is responsible for training
Correct answer: Issue a driver violation for failing to provide records in an inspectable format
Drivers are required to be able to display their ELD records; failure to do so is a driver-level violation for not providing records in the required format.
