ELD Compliance: The Complete Guide

What the ELD mandate is

The Electronic Logging Device rule — 49 CFR §395.20 through §395.38 — was finalized in December 2015 and fully enforced beginning December 16, 2019. It requires most commercial motor vehicle (CMV) drivers subject to the Hours of Service regulations to use an FMCSA-registered ELD to record their Records of Duty Status (RODS). Paper logs and grandfathered Automatic On-Board Recording Devices (AOBRDs) were phased out.

The goal of the rule is straightforward: automate RODS data capture, reduce falsified logs, and make HOS enforcement auditable. Roadside inspections can now pull HOS data directly from the device using the FMCSA eRODS data-transfer standard — via USB, Bluetooth, email, or web service.

Who is required to use an ELD

The mandate applies to drivers of commercial motor vehicles operated in interstate commerce who are required to keep RODS under §395.8. In practice, that means:

• Trucks with a gross vehicle weight (GVW) or GVWR of 10,001 lbs or more
• Vehicles designed to transport 16 or more passengers (including driver), or 9 or more passengers for compensation
• Any vehicle transporting hazardous materials in quantities requiring placards

Intrastate-only operators may also be subject to state-level ELD requirements that mirror the federal rule — check with your state DOT if your operations don't cross state lines.

The Hours of Service limits you’re recording

ELDs exist to enforce the HOS rules. For property-carrying CMV drivers under §395.3:

• 11-hour driving limit — may drive up to 11 hours after 10 consecutive hours off duty
• 14-hour on-duty window — driving must end no later than 14 hours after coming on duty
• 30-minute break — required after 8 cumulative hours of driving (interruption can be off-duty or sleeper berth)
• 60/70-hour weekly limit — 60 hours in 7 consecutive days (carriers not operating 7 days/week) or 70 hours in 8 consecutive days; may restart with 34 consecutive hours off duty
• Sleeper berth provision — driver may split the 10-hour off-duty period into one period of at least 7 consecutive hours in the sleeper berth and another of at least 2 hours (off-duty or sleeper), neither counting against the 14-hour window

Passenger-carrying drivers under §395.5 follow similar but distinct limits: 10-hour driving / 15-hour on-duty window / 8 consecutive hours off duty required between shifts.

The four ELD exemptions most fleets miss

The rule carves out four exemption categories. If you qualify, you don’t need an ELD (but you still need to track HOS through an alternate method):

1. Pre-2000 engine model year — drivers operating vehicles manufactured before model year 2000 are exempt because the engine ECM cannot reliably interface with an ELD. Vehicle age, not body age, matters; a 1999 truck re-engined with a 2001 powerplant is no longer exempt.
2. Driveaway-towaway operations — when the vehicle being driven is the commodity being delivered (e.g., delivering new trucks to dealerships), ELD requirements are waived. Trailer-mounted vehicles qualify as towaway; unladen tractors moving under their own power count as driveaway.
3. Short-haul (§395.1(e)) — drivers operating within a 150-air-mile radius of their work reporting location who return to that location each day and are released from duty within 14 hours. Property-carrying drivers can use this exemption 8 days within any 30-day rolling period; if they exceed that, ELD compliance is required.
4. Limited RODS requirement — drivers who aren’t required to maintain RODS more than 8 days in any 30-day period. Typically applies to regional short-haul drivers who rarely exceed the short-haul exemption window.

Registered vs. unregistered devices — why it matters

FMCSA maintains a registered-device list at fmcsa.dot.gov/registered-eld-list. Only devices on this list are compliant. Devices can be — and have been — de-registered when FMCSA audits reveal they fail to meet the technical specification. In 2024, FMCSA removed roughly 500 previously-listed devices from the registry over a single six-month window. If your ELD vendor is removed, your fleet is instantly out of compliance and needs to transition within 60 days.

Before committing to a multi-year ELD contract, verify the device is currently registered and check the vendor’s history. Vendors who have had multiple devices de-registered have a higher compliance risk than vendors with a clean track record.

How Dockex fits the ELD stack

Dockex does not sell an ELD. We read HOS data from your existing ELD via the manufacturer’s API — Samsara or Motive — and live GPS from Geotab. More providers are added as customers request them. That read-only integration means:

• Your drivers keep the ELD app they’re trained on
• Your ELD contract stays where it is — no cancellation fees
• HOS violations are surfaced in Dockex alongside DQ files, IFTA mileage, and maintenance
• When you file IFTA, Dockex can pull jurisdictional mileage from the same ELD feed — no CSV upload step

The result is that you get DOT compliance + filing + HOS monitoring in one dashboard without replacing your logging hardware.
