If you are required to keep a Record of Duty Status (RODS), you are generally required to use an ELD.

An electronic logging device (ELD) connects to a truck’s engine and records driving time, engine hours, vehicle movement, and location. It replaces paper logbooks with a digital record that can be reviewed during inspections. These devices must meet federal technical standards and be registered for use.

Who has to use an ELD?

Most drivers operating commercial motor vehicles in interstate commerce are required to use an ELD.

This typically includes drivers who:

• Operate vehicles over 10,001 pounds
• Cross state lines or haul freight that is part of interstate commerce
• Are required to maintain Hours of Service logs

This applies to most long-haul drivers and many regional drivers.

Who is exempt from ELD rules?

Some drivers are not required to use an ELD even if they operate a commercial vehicle.

Common exemptions include:

• Drivers who use paper logs no more than 8 days within any 30 days
• Short-haul drivers operating within a 150 air-mile radius who return to the same reporting location within 14 hours
• Driveaway-towaway operations where the vehicle being driven is the load
• Vehicles with engines manufactured before model year 2000

Even with an exemption, drivers may still need to follow Hours of Service limits.

What is the short-haul exemption?

The short-haul exemption allows certain drivers to avoid keeping a full Record of Duty Status.

To qualify, you must:

• Stay within a 150 air-mile radius of your reporting location
• Return to that location at the end of your shift
• Complete your workday within 14 hours

If you go beyond these limits, you must begin recording logs and may be required to use an ELD.

What do ELDs actually track?

ELDs automatically record key data tied to vehicle operation.

They record:

• Driving time when the vehicle is moving
• Engine hours
• Miles driven
• Vehicle location at duty status changes
• Vehicle location at engine power-up and shutdown
• Vehicle location at 60-minute intervals while driving
• Duty status selections made by the driver

Drivers are responsible for selecting the correct duty status, including on-duty, off-duty, and sleeper berth.

How do ELD rules affect your driving hours?

ELDs do not change Hours of Service limits, but they make those limits strictly enforceable.

The main HOS rules include:

• Up to 11 hours of driving after 10 consecutive hours off duty
• A 14-hour on-duty window
• A 30-minute break after 8 hours of driving
• A 60 or 70-hour limit over 7 or 8 days

Because ELDs track driving automatically, once you reach your limit, you must stop driving.

What are personal conveyance and yard move?

ELDs include special driving categories that must be used correctly.

Personal conveyance is off-duty driving for personal use only. It cannot be used to move a load forward or extend available driving time.

Yard move is on-duty, not-driving time used when moving a vehicle within a yard, terminal, or private property.

Misusing either status can lead to violations even if the total hours appear compliant.

Can logs be edited in an ELD?

Yes, but edits are controlled.

Drivers can edit their own logs to correct mistakes. Carriers can suggest edits, but drivers must review and accept or reject those changes. All edits remain in the record, and the original log is not deleted.

What happens if your ELD malfunctions?

If your ELD stops working, you can switch to paper logs temporarily, but you must follow specific steps.

You must:

• Inform your carrier within 24 hours
• Reconstruct your logs for the current day and the previous 7 days
• Continue recording your hours manually
• Ensure the ELD is repaired or replaced within 8 days

Failing to follow these steps can result in violations.

What are supporting documents?

Supporting documents are records used to verify your log entries.

These include:

• Fuel receipts
• Bills of lading
• Dispatch records
• Toll receipts

Carriers must keep these records, and they may be used during audits or inspections to confirm that your logs match your actual activity.

What happens during a roadside inspection?

During an inspection, an officer may request your logs.

You must be able to:

• Display your logs on the ELD screen
• Transfer logs electronically through email or web service

If you have supporting documents with you, an officer may also request to review them. Your logs must be current and accurate at the time of inspection.

Where drivers get in trouble with ELDs

Most violations come from small mistakes rather than big misunderstandings.

Common issues include:

• Forgetting to change duty status at the right time
• Misusing personal conveyance to extend driving time
• Running too close to the 14-hour limit without planning ahead
• Not keeping logs current throughout the day

ELDs leave very little room for error. Once your time is gone, you cannot adjust it later, so planning matters.

What are the penalties for ELD violations?

Violations can lead to fines, out-of-service orders, and safety score impacts.

Common violations include:

• Not using an ELD when required
• Falsifying logs or making improper edits
• Missing or incomplete records
• Driving beyond allowed Hours of Service limits

Repeated violations can affect both the driver and the carrier.

Frequently asked questions

What is an ELD?
An ELD is a device connected to a truck’s engine that automatically records driving time and replaces paper logbooks.

Do all drivers need an ELD?
No, but most drivers who must keep Hours of Service logs are required to use one unless they qualify for an exemption.

Can you still use paper logs?
Yes, but only under limited exemptions or during a temporary ELD malfunction.

What is the short-haul exemption?
It allows drivers to operate within a 150-mile radius and complete their shift within 14 hours without keeping a full log.

What happens if your ELD stops working?
You must switch to paper logs, reconstruct recent logs, and have the device repaired within 8 days.

ELD rules are meant to make Hours of Service tracking consistent and enforceable. Once you understand what the device records, how exemptions work, and where mistakes usually happen, it becomes easier to stay compliant and avoid violations.

On April 2, the agency confirmed that the HERO ELD, identified under model number HRS with ELD identifier HRS205, has been placed on the revoked list. This means the device no longer meets federal standards required for compliance.

According to the agency, the device was removed due to a “failure to meet the minimum requirements” outlined in Title 49 CFR Appendix A to Subpart B of Part 395. These regulations define the technical and functional standards all electronic logging devices must follow. Officials did not provide additional details about the specific deficiency that led to the removal.

Carriers currently using the HERO ELD have a limited window to make changes. FMCSA is allowing up to 60 days to transition to a compliant device. During that time, operators must ensure they remain in compliance with hours of service rules.

Drivers and fleets using the affected unit are expected to take immediate steps. This includes stopping use of the revoked device and switching to paper logs or approved logging software to record hours of service. A replacement ELD must be installed before June 2 using a device that appears on the FMCSA’s registered list.

The issue also brings renewed attention to how ELDs enter the market. When the mandate first took effect, manufacturers were allowed to self-certify their devices rather than going through a formal approval process. That approach made it easier for new technology to roll out quickly, but it also raised concerns about quality and compliance.

Recent comments from FMCSA leadership suggest those concerns are now being addressed more aggressively. Speaking at the Mid America Trucking Show in Louisville, Kentucky, FMCSA Administrator Derek Barrs said roughly 430 ELD companies attempted to self-certify within the past six months. The agency is now taking steps to ensure those devices are properly vetted.

Barrs has also pointed to broader issues tied to self-certification across multiple areas of the industry, including entry-level driver training programs and medical examiners.

“The issue is that it opens the door up for a lack of oversight, which opens the door for potential fraud occurring,” Barrs said. “People are not following the rules because no one is watching. I use the no one’s minding the story type of analogy. If nobody’s watching, then I’m going to find a way to skirt the system, which then compromises safety.”

With another device now removed from the approved list, the message is clear that compliance standards are being enforced more closely. Fleets relying on electronic logging devices should verify that their equipment meets current requirements to avoid disruptions and stay aligned with federal regulations.
