An electronic logging device (ELD) connects to a truck’s engine and records driving time automatically. Most drivers who must keep hours-of-service logs have to use one, and it must appear on FMCSA’s registered ELD list.
Our ELD services pair the Simplex ELD app and web portal with bilingual training and 24/7 support, so your team can keep the records the rule requires.
If your drivers must keep records of duty status, your trucks need ELDs. The rule has applied since December 18, 2017: a motor carrier operating commercial motor vehicles must install ELDs and require its drivers to use them (49 CFR 395.8).
Under federal rules, a commercial motor vehicle in interstate commerce is one that has a weight rating or weight of 10,001 pounds or more, is designed or used to carry more than 8 passengers (including the driver) for pay or more than 15 without pay, or hauls hazardous materials in placarded amounts (49 CFR 390.5T). Paper logs are still allowed for drivers who:
A truck from model year 2000 or newer still needs an ELD even if its engine has no electronic control module; it must use a device that can capture the required data another way. Our ELD compliance guide covers the in-cab packet, malfunctions, and backups.
An ELD records who drove, when, where, and for how long. It is synchronized with the engine, captures power status, motion, miles, and engine hours, and switches the driver to driving status automatically once the truck moves, unless the driver has already selected personal use or yard moves (Appendix A to Subpart B of Part 395).
Yes, within limits. Drivers can edit, add missing information, and annotate records, and every change needs an annotation. A carrier can propose edits, but the driver must accept or reject them (49 CFR 395.30). What no one can do is shorten driving time the ELD recorded automatically, except to fix a team-driver mix-up or to assign unidentified driving to the right driver.
| Limit | Rule |
|---|---|
| Driving | 11 hours, after 10 consecutive hours off duty |
| Duty window | No driving after the 14th hour since coming on duty |
| Break | A 30-minute break from driving after 8 hours of driving time |
| Weekly | No driving after 60 on-duty hours in 7 days, or 70 in 8 days; 34 hours off duty restarts the count |
Start with FMCSA’s list: carriers may use only an ELD that appears on its registered list (49 CFR 395.22). Providers self-certify their devices, and FMCSA states that it does not endorse any ELD. Then check these points before you buy:
An honest caveat: the registered list tells you a provider certified its device as compliant. It does not tell you how well the device will work in your trucks, so test the roadside transfer with your drivers before you roll it out.
Simplex ELD comes in two plans, ELD Lite and ELD Premium, each with a mobile app for Android and iOS and a web management portal. As of October 5, 2026, FMCSA’s registered list shows our app as “SimpleX ELD 2 Go” (ELD identifier CAUS02).
See the full plan comparison on our Simplex ELD page. Current customers sign in through the Simplex ELD Portal on our client portals page. If the portal’s mileage reports feed your fuel tax return, our IFTA permits team can help with the quarterly filing.
An ELD records the hours, but the carrier still owns the review. You must make sure unidentified driving is reviewed and either annotated or assigned to the right driver (49 CFR 395.32). You must also keep supporting documents, such as bills of lading, dispatch records, expense receipts, and payroll records, that verify each driver’s on-duty time (49 CFR 395.11).
Those records are what an auditor or investigator asks for. Our compliance programs include HOS management, and our DOT safety compliance team covers ELD and hours of service with your other FMCSA obligations. ¿Prefiere español? Lea nuestra página de ELD y horas de servicio.

An electronic logging device that connects to the truck’s engine and automatically records driving time, location, miles, and engine hours, so drivers can keep their hours-of-service records electronically. It replaced paper logs for most drivers on December 18, 2017.
Yes. As of October 5, 2026, FMCSA’s registered list shows our app as “SimpleX ELD 2 Go,” ELD identifier CAUS02. FMCSA does not approve or endorse any ELD; providers self-certify their devices and FMCSA publishes the list.
Use the Simplex ELD Portal link on our client portals page. Drivers use the mobile app on their Android or iOS device.
Call the number at the top of this page or use the form below and select ELD. Both Simplex ELD plans include 24/7 support.
At a roadside inspection, the driver is cited and placed out of service for 10 hours (8 hours for a passenger carrier). The driver may then finish the trip on paper logs, but a driver dispatched again without a compliant ELD faces the same out-of-service procedure.
