Lesson 3.1 — ELD Display on Demand

Why this matters

An inspector at the roadside asks one question: "show me your logs." You have about two minutes to display the screen or transfer the file. If you can't — citation under 49 CFR 395.24(d). This is one of the most common HOS-related citations at CMV roadside inspections.

This is the most-cited HOS violation in your operation. It is also the easiest to prevent. The fix is knowing where two buttons are in your ELD app — "Roadside Inspection" or "DOT" — and pressing them before the officer reaches the window.

49 CFR 395.24(d) — Driver use of ELD.

"On request by an authorized safety official, a driver must produce and transfer from an ELD the driver's hours-of-service records in accordance with the instruction sheet provided by the motor carrier."

Two ways to produce the data:

• Display — show the ELD screen so the officer can see the graph and log details. The display must be viewable from outside the cab (you may need to untether and hand it out the window).
• Transfer — send the eRODS file electronically. Two transfer types: telematics (web service or email — automatically routed to FMCSA's eRODS server) or local (USB or Bluetooth to the officer's device).

The officer chooses which method. Most will request a transfer first; if that fails, they'll ask to see the display as a backup.

1 The graph

A 24-hour grid showing your duty-status changes — Off Duty, Sleeper Berth, Driving, On Duty Not Driving. Plotted across the day. This is the visual the officer scans first.

2 Log details

The list view — each duty-status change with timestamp, location, odometer, and event origin (driver-entered vs auto-recorded). Required for the current 24-hour period AND the previous 7 consecutive days.

3 Header info

Your name, driver's license number, the carrier's USDOT number, the power unit number, today's date, the time zone, and the ELD provider name. The ELD shows this automatically; you don't enter it for inspection.

4 Unidentified driving records

If the truck moved while no driver was logged in, those minutes show up under "unidentified driver" and you can see them — and so can the inspector. If there are unidentified records in the last 8 days, the officer expects an explanation (typically: another driver moved the truck and forgot to log in).

This is what happens at the window. Most ELD apps have a "DOT Inspection" or "Roadside Inspection" button on the main screen. The flow looks like:

1. Officer asks for your log.
2. You tap DOT Inspection in the app.
3. The app asks: display or transfer?
4. Transfer: the officer gives you a routing code. You type it into the comment field. You confirm. The file uploads to FMCSA's eRODS server. The officer's tablet pulls it from there.
5. Display: you hand the unmounted ELD (or the screen) to the officer, or hold it at the window where they can read it.

If the transfer fails (no signal, server down), switch to display. The officer will document the device as potentially non-compliant, but you will not be cited for 395.24(d) as long as you produced the data.

49 CFR 395.34 — ELD malfunction protocol. If the ELD will not work, the driver must:

1. Note the malfunction and notify the carrier within 24 hours in writing.
2. Reconstruct the current 24-hour period and the previous 7 days on a paper log (graph-grid).
3. Continue with paper logs until the ELD is fixed.

The carrier has 8 days to repair, replace, or service the ELD. Past 8 days, the carrier must request an extension from the FMCSA Division Administrator.

You must keep blank paper log sheets in the cab for at least 8 days' worth (395.22(4)). If an inspector asks and you have no paper logs and no working ELD — separate citation.

1. Practice the transfer once a week. Open the app, find "DOT Inspection," tap through to the screen where you would enter a routing code. Cancel before submitting. You want the muscle memory.
2. Know where the display lives. Some apps put the graph view two menus deep. Find it now, not at the window.
3. Carry paper log blanks. 8 days' worth. $3 at a truck stop. If the ELD dies, you have a backup that satisfies 395.22(4).
4. If the transfer fails — switch to display immediately. Don't argue with the officer about why the upload isn't working. Show the screen.
5. Save the malfunction notice. If the ELD genuinely malfunctioned, text or email the carrier the same day. Time-stamped. That's your defense for the paper-log days.

• ○ A printed copy only
• ✓ Either a display of the ELD screen OR an electronic transfer of the eRODS file
• ○ Paper logs from the last 30 days
• ○ A photo of your driver's license

• ○ Current 24-hour period only
• ✓ Current 24-hour period plus the previous 7 consecutive days
• ○ Current 24-hour period plus the previous 30 days
• ○ The entire current month

• ○ Tell the officer to come back later
• ○ Refuse the inspection since the transfer cannot complete
• ✓ Switch to display — show the ELD screen as the backup
• ○ Reset the ELD and start over

• ○ Stop driving immediately until the ELD is repaired
• ✓ Notify the carrier within 24 hours in writing AND reconstruct the current 24-hour period and previous 7 days on paper logs
• ○ Continue driving and report the malfunction at end of week
• ○ Use a backup ELD provided by the customer

• ○ At least 1 day
• ○ At least 3 days
• ✓ At least 8 days
• ○ At least 30 days

Why: 8 days of blank graph-grid sheets — enough to cover the current day plus the previous 7 if you need to reconstruct after a malfunction. They cost roughly \$3 at any truck stop and avoid a separate 395.22(4) citation.
