ELD Malfunction: What to Do (FMCSA 8-Day Rule)

An ELD malfunction isn't an automatic violation — but ignoring the rules is. FMCSA §395.34 lays out exactly what to do, and you have 8 days to fix it.

What counts as a malfunction

A malfunction is anything that stops the ELD from accurately recording or transferring your hours of service — power issues, engine-sync loss, data-transfer failure, or missing data. A temporary "diagnostic event" isn't always a full malfunction, but treat persistent problems seriously.

The steps (FMCSA §395.34)

Note it. Write down the malfunction and the date you noticed it.
Notify your carrier within 24 hours in writing.
Switch to paper logs. Reconstruct your record of duty status for the current 24 hours and the past 7 days if they aren't already retrievable from the device, and keep logging on paper until the ELD is fixed.
Repair or replace within 8 days. The carrier must correct the malfunction within 8 days of discovery (or request an extension from the FMCSA Field Office).

How TruckSpot handles it

TruckSpot ELD flags malfunctions and diagnostic events on screen, keeps your last 7+ days retrievable, and includes a built-in paper-logs mode so you can stay compliant during the gap — then resume automatic logging once the device reconnects.

Frequently asked questions

Is an ELD malfunction a violation?

Not by itself. You're compliant as long as you follow §395.34 — notify your carrier, switch to paper logs, and repair within 8 days.

How long can I drive on paper logs?

Until the ELD is repaired, up to 8 days from discovery. Beyond that, the carrier must request an extension from the FMCSA.

What if my phone dies, not the ELD?

Keep a charger in the cab. If you genuinely can't access the app, fall back to paper logs and reconstruct the records once you're back online.
