ELD Stands for Electronic Logging Device
ELD stands for Electronic Logging Device. It's a piece of hardware that connects to your truck's engine control module (ECM) and automatically records your driving time, engine hours, vehicle movement, and miles driven. The data it captures is what federal regulators use to verify Hours of Service (HOS) compliance.
Before ELDs, drivers kept paper logbooks. The ELD mandate, enforced by the Federal Motor Carrier Safety Administration (FMCSA), phased out paper logs for most commercial motor vehicle drivers. If you're running regulated loads, your ELD is a compliance requirement, not optional equipment.
For a broader look at how compliance tools like ELDs fit into your overall operation, see our guide at HaulerPro Carrier Guides.
What Does an ELD Actually Do?
An ELD records:
- Driving time against your HOS limits (11-hour driving limit, 14-hour on-duty window, 70-hour/8-day rule, etc.)
- Engine hours and vehicle motion so the log can't be fudged manually
- Location data at key events, including when duty status changes
- Driver identity so each log is tied to a specific operator
During a roadside inspection or audit, an officer can request your ELD records. The device displays your logs and, in many cases, can transmit them electronically. Missing or falsified records are a serious violation that can put your operating authority at risk. Auditors commonly review ELD data going back several months, so consistent, accurate records matter throughout the year, not just during inspection season.
Who Is Required to Have One?
The FMCSA ELD mandate applies broadly to commercial motor vehicle drivers who are required to prepare HOS records of duty status. That covers most interstate CDL operations. There are some exemptions, including:
- Drivers operating under the short-haul exemption (operating within a 150 air-mile radius and meeting other criteria)
- Drivers of vehicles manufactured before model year 2000
- Drivers using the timecard exception (non-CDL short-haul)
- Certain agricultural operations, drive-away/tow-away operations, and other limited exemptions
Exemptions are specific and have conditions attached. Verify your status directly with FMCSA rather than assuming an exemption applies. Regulations change, and enforcement interpretations can shift.
Does HaulerPro Replace an ELD?
No. HaulerPro is a transportation management system (TMS), not an ELD. The two tools do different jobs.
Your ELD handles HOS compliance and regulatory logging. HaulerPro handles everything around the load: dispatch, documents, driver management, invoicing, IFTA mileage, and expenses. Drivers update load status manually from the HaulerPro driver app, which gives dispatch full visibility on every load without requiring GPS hardware.
HaulerPro does not currently integrate with ELD hardware or pull HOS data from your device. If you're comparing TMS options that do offer ELD integration, that's a real feature difference to weigh. What HaulerPro gives you is a clean, fast system built around how independent carriers actually run their business, without the complexity and pricing that comes with tools designed for much larger fleets.
How ELDs and a TMS Work Together in Practice
Think of it this way: your ELD keeps you legal on the road. Your TMS keeps your business running off the road.
A driver finishes a load, taps a status update in HaulerPro, and the dispatcher sees it immediately. The rate confirmation was already scanned and attached to the load record. The invoice goes out with the POD auto-attached. IFTA mileage for the run is captured automatically from the dispatched route across the 48 contiguous states. Meanwhile, the ELD has been quietly logging the hours behind all of that.
Neither tool replaces the other. Carriers who are serious about running a clean, profitable operation typically use both.
Choosing an ELD
FMCSA maintains a registry of self-certified ELD devices at fmcsa.dot.gov. The list is public. Common providers include Motive (formerly KeepTruckin), Samsara, and many others. Pricing, hardware requirements, and subscription terms vary. Verify any device is on the FMCSA registered list before purchasing, because not all devices marketed as ELD-compliant have been properly registered.
Look for:
- Registration on the FMCSA ELD list
- Simple roadside display and transfer options
- Reliable driver app
- Support you can actually reach when something breaks at 2 a.m.
