Sharing ELDs: Can Two Drivers Use the Same Device? Best Practices and Guidelines

Key Takeaways:

• Two team drivers can use the same ELD in a commercial motor vehicle when the device supports co-driver operation.
• Each driver must use a separate driver account with unique credentials. Drivers must never share one login.
• Before the vehicle moves, the team must confirm which logged-in driver is the active driver so automatic driving time is assigned correctly.
• Co-drivers cannot switch driving roles on the ELD while the vehicle is moving, although a non-driving co-driver may update their own record if the device permits it.
• If driving time is assigned to the wrong team driver, the record may be reassigned under the team-driver correction process, with both co-drivers confirming the change.

Can two drivers use the same ELD? Yes. A team can share the physical ELD installed in or connected to the same commercial motor vehicle. What they cannot share is a driver account.

Each driver needs an individual account, unique login credentials, and a separate record of duty status. The ELD must identify the active driver, retain each co-driver’s records, and display the data required for both logged-in drivers. A careful handoff before the vehicle moves keeps automatic driving time attached to the person actually behind the wheel.

This guide explains how ELD sharing works for team drivers, which steps belong in a driver changeover, how to correct misassigned driving time, and what fleets should look for in a team-driving ELD.

Can Two Drivers Legally Share One ELD?

Yes. FMCSA’s technical guidance specifically addresses team drivers using the same ELD. The agency states that an ELD used by team drivers must display the data for both co-drivers who are logged into the system. The physical device is shared, but each driver remains responsible for an individual electronic record.

FMCSA’s Using ELDs guidance says a driver must have one driver account with a carrier, with a unique identification number and password. The carrier creates and manages those accounts. A shared username or password defeats the ELD’s ability to identify who was driving and should not be used.

Shared element	Allowed?	Requirement
Physical ELD in the vehicle	Yes	The device must support team-driver or co-driver operation.
Driver account or credentials	No	Each driver uses a unique account and password.
Vehicle and trip	Yes	Each driver’s duty status and driving events remain in that driver’s record.
Hours-of-service availability	No	Each driver must independently comply with the applicable HOS limits.

How Team-Driver ELD Accounts Work

Team-driving interfaces vary, but the regulatory responsibilities are consistent. Both drivers log in with their own credentials. The ELD identifies one person as the active driver and the other as a co-driver. When the vehicle moves, automatically recorded driving time is associated with the active driver.

Before a changeover, the vehicle should be safely stopped. The outgoing driver records the appropriate duty status for what they will actually do, such as sleeper berth, off duty, or on-duty not driving. The incoming driver becomes the active driver and confirms the correct status before moving the vehicle. Follow the device manufacturer’s instructions because button names and switching steps differ among registered ELDs.

Being the co-driver does not automatically mean a particular duty status. A co-driver might be in the sleeper berth, off duty, or on duty depending on the facts. Each driver must select and certify a status that accurately describes their own activity.

Active Driver and Co-Driver

The active-driver designation controls which account receives automatically recorded driving time. The co-driver designation connects the other team member to the trip and supports the team-driver correction process when an event is assigned incorrectly.

FMCSA explains that a logged-in co-driver who is not operating the vehicle may make entries in their own record while the vehicle is moving. The drivers cannot switch driving roles on the ELD while the vehicle is in motion. The actual handoff should occur only after the vehicle is stopped.

A Safe ELD Handoff Checklist for Team Drivers

1. Stop the vehicle safely. Do not try to switch the active driver while the vehicle is moving.
2. Review both names on the ELD. Confirm that both drivers are logged in under their own accounts and identified as co-drivers.
3. Update the outgoing driver’s status. Select the status that matches what the outgoing driver will actually do.
4. Switch the active driver. Use the ELD’s documented team-driver procedure and verify the incoming driver’s name is shown as active.
5. Check available hours. The incoming driver reviews their own clocks and current-day record before driving.
6. Move only after confirmation. Automatic driving time should begin on the incoming driver’s account.
7. Review the handoff later. Both drivers check for unidentified or misassigned events before certifying their daily records.

A clean handoff is an identity and recordkeeping check, not a transfer of one driver’s log to another. The ELD continues to maintain separate records for each account.

What Happens When No Driver Is Logged In?

If the commercial motor vehicle moves without an authenticated driver, the ELD records the movement under an unidentified-driver profile. FMCSA instructs drivers to review unassigned driving time after logging in. A driver should accept an event that belongs to them or add an annotation explaining why an event is not theirs, using the device’s review process.

Carriers should review unidentified-driving reports and propose assignment to the appropriate driver when supported by the facts. Those records should not be deleted merely to clean up a dashboard. The unidentified-driver profile is part of the ELD’s audit trail.

How to Correct Driving Time Assigned to the Wrong Co-Driver

Automatically recorded driving time generally cannot be changed to non-driving time. Team operations have a narrow correction process for events recorded under the wrong co-driver.

Under 49 CFR 395.30(c)(3), driving time may be reassigned between team drivers when there was a mistake and both drivers were indicated in one another’s records as co-drivers. FMCSA’s team-driver reassignment guidance states that each co-driver must confirm the change before it takes effect.

A practical correction workflow is:

1. Identify the exact driving segment and confirm who actually operated the vehicle.
2. Verify that the two drivers were shown as co-drivers for the relevant period.
3. Use the ELD’s edit or reassignment function rather than creating a replacement event.
4. Add a concise, truthful annotation explaining the mistaken assignment.
5. Have both drivers review and confirm the proposed reassignment.
6. Recheck each driver’s remaining hours and certify the corrected daily record.

The correction retains the original event and edit history. It does not permit a fleet to erase driving time, convert actual driving to off duty, or assign time without the required driver confirmation.

Team Driving Does Not Combine HOS Clocks

Sharing an ELD or vehicle does not pool the drivers’ available hours. Each driver has an individual 11-hour driving limit, 14-hour driving window, break requirements, weekly limit, and restart calculation when those provisions apply. Review Geosavi’s Hours of Service guide for a broader explanation.

The same principle applies to sleeper-berth time. One driver may rest while the other drives, but each driver’s record must independently satisfy the applicable sleeper-berth requirements. The presence of a co-driver does not automatically make a rest period qualifying sleeper-berth or off-duty time.

Drivers should review their own records and certify them separately. A fleet manager can review records and propose corrections, but the driver remains responsible for confirming or rejecting changes and certifying the accuracy of their RODS.

Features to Check in an ELD for Team Driving

A compliant product must meet the federal technical specifications, but workflow quality still varies. Before assigning an ELD to a team, confirm that drivers and managers understand these functions:

• Simultaneous driver and co-driver login
• A clear active-driver indicator
• A stationary role-switch workflow
• Display of required data for both logged-in co-drivers
• Separate duty-status records and certification for each driver
• Review and assignment of unidentified-driving events
• Team-driver reassignment with confirmation by both drivers
• Roadside display and data-transfer functions
• Diagnostic and malfunction indicators

Carriers should verify that the exact model appears on FMCSA’s registered, self-certified ELD list. Registration does not replace training: drivers still need the user manual and hands-on practice with co-driver login, switching, edits, certification, and data transfer.

Common Shared-ELD Problems and Responses

Problem	Correct response
The incoming driver cannot log in	Do not use the other driver’s credentials. Stop and contact the carrier or ELD provider for account support.
The vehicle moved with no active driver	Review the unidentified-driving event and assign or annotate it according to the facts.
Driving time went to the wrong team member	Use the team-driver reassignment process; both co-drivers must confirm the change.
The drivers notice the wrong active name while moving	Do not interact with the ELD while driving. Stop safely, then use the documented correction workflow.
A co-driver’s rest status is wrong	Correct that driver’s own record with an accurate status and annotation; do not alter the active driver’s driving event.
The ELD will not display or transfer required records	Follow the device’s diagnostic or malfunction instructions and the carrier’s compliance procedure.

For a wider operational review, use Geosavi’s ELD compliance checklist. It helps carriers verify account setup, required documents, driver training, inspections, and record handling without relying on assumptions about a particular interface.

Best Practices for Carriers Managing Team Drivers

• Create one unique driver account per driver and prohibit credential sharing.
• Train teams on the exact active-driver and co-driver workflow for their ELD model.
• Require role changes to be completed while the vehicle is stopped.
• Review unidentified-driving and reassignment reports promptly.
• Teach drivers how proposed edits and confirmations appear in the system.
• Keep device instructions and required supporting materials available in the vehicle.
• Verify that each driver separately reviews and certifies their daily record.

The Bottom Line on Sharing ELDs

Two drivers can use the same ELD, but the device must preserve two distinct driver identities and records. Both drivers should log in with their own credentials, identify one another as co-drivers, and confirm the active driver before the vehicle moves. They should switch roles only while stopped and review unidentified or misassigned events before certification.

A strong team-driving process is simple enough to repeat at every handoff and precise enough to preserve the audit trail. Fleets comparing systems can review Geosavi’s guide to the best electronic logging devices for fleets or contact Geosavi for product support.
