The Electronic Logging Device mandate, which took full effect in 2017, replaced paper logbooks with electronic tracking of a driver's Hours of Service for the large majority of commercial truck drivers in the United States. Nearly a decade later, it remains one of the most consequential compliance requirements a new trucking company needs to understand before putting a truck on the road.
Getting ELD compliance wrong, whether through an unregistered device or a misunderstanding of the exemptions, is one of the more common and expensive mistakes new carriers make in their first year.
In This Guide
1. What an ELD Actually Is
An Electronic Logging Device automatically records driving time by connecting to a truck's engine, capturing data like engine hours, vehicle movement, and location, and compiling it into a Hours of Service record the driver can no longer manually adjust the way a paper log could be. The device must be registered on the FMCSA's official list of certified ELDs to count as compliant.
2. Who Must Comply
Most drivers required to keep Records of Duty Status under existing Hours of Service rules must use a registered ELD, which covers the large majority of interstate commercial truck drivers operating vehicles over 10,001 pounds. This applies equally to a single owner-operator and a large fleet, there's no small-carrier exemption from the rule itself.
3. Who's Exempt
A handful of specific exemptions exist. Drivers who operate within a 150 air-mile radius of their work location and return to the same location within 14 hours (the short-haul exemption) can use time cards instead of an ELD. Drivers of vehicles manufactured before 2000, and those who use paper logs for no more than 8 days in any 30-day period, also qualify.
Qualifying for an exemption doesn't mean skipping Hours of Service tracking entirely, it means using an allowed alternative method, and a carrier still needs to be able to document why a driver qualifies for the exemption if asked during an inspection or audit.
4. The HOS Rules an ELD Tracks
An ELD enforces the underlying Hours of Service rules it's tracking: an 11-hour driving limit within a 14-hour on-duty window, a mandatory 10 consecutive hours off duty between shifts, and a 60/70-hour limit over 7/8 consecutive days. The device must store at least 8 days of current driving data, retrievable by roadside inspectors.
5. Choosing a Compliant Device
Before purchasing an ELD, confirm it appears on the FMCSA's current list of registered devices, since using a non-registered device, even one marketed as ELD-compliant, is itself a violation. Beyond basic compliance, devices vary in integration with dispatch and accounting software, which is worth considering for a carrier planning to grow beyond one truck.
6. Common Violations and Penalties
The most common ELD violations are operating without a registered device, failing to have a driver properly trained on how to use it, and HOS violations that the device itself now makes far harder to hide than a paper log did. Penalties can run $2,500 or more per violation and can affect a carrier's CSA safety score, which our guide on CSA scores and safety ratings covers in more detail.
Frequently Asked Questions
Do all trucking companies need an ELD?
Most drivers required to keep Hours of Service records under existing FMCSA rules need a registered ELD, which covers the large majority of interstate commercial drivers regardless of fleet size. Specific exemptions exist for short-haul operations, older vehicles, and limited paper-log use.
What is the short-haul ELD exemption?
Drivers who operate within a 150 air-mile radius of their work location and return within 14 hours can use time cards instead of an ELD. This exemption is common for local delivery and regional operations that don't involve long-haul routes.
What happens if a carrier uses a non-compliant ELD?
Using a device not on the FMCSA's registered list is itself a violation, separate from any Hours of Service issue, and can result in fines and affect the carrier's safety rating during a roadside inspection or compliance review.
