ELD FAQs and Best Practices

What is an ELD?

An ELD (Electronic Logging Device) is a piece of technology that automatically records a driver’s driving time and provides more accurate hours-of-service records. It tracks when the engine is on, when the vehicle is moving and how many miles have been driven. An ELD automatically switches to driving mode if the vehicle is going at least 5 mph and includes diagnostic indicators about the vehicle and the ELD itself.

Carriers using paper logs or logging software had to install ELDs and train drivers and staff members how to use them by December 18, 2017. Carriers who used AOBRDs before December 2017 have until December 16, 2019 to install ELDs.

Do I need some sort of expensive, specialized device to stay compliant?

As a matter of fact, you don’t. Compliant ELD systems can run on smartphones or tablets as long as the device is mounted, and the driver can easily see it.

Make sure the ELD you’re considering is on the FMCSA’s list of registered ELDs. To comply with the rule, the ELD must:

  • Have separate accounts for drivers and administrative ELD users.
  • Have “integral synchronization” with the engine control module that automatically records data like engine power status and vehicle motion status.
  • Automatically record all driving time, and record the date, time, location, engine hours, vehicle miles, and driver identification.
  • Record location data:
    • In 60-minute intervals when the vehicle is moving.
    • When the driver turns the vehicle on or off.
    • Whenever duty status changes.
    • During personal use or yard moves.
  • Record location within a one-mile radius when on-duty and driving.
  • Reduce location accuracy to a 10-mile radius when the vehicle is being used for personal conveyance to help protect driver privacy.
  • Synchronize ELD time with UTC (coordinated universal time).
  • Save data for the current 24-hour period and the last seven consecutive days.
  • Prevent anyone from altering or erasing the original ELD logs.
  • Require drivers to review unidentified driver records – and either accept the time assignment or say the records aren’t theirs.
  • Allow a driver to obtain a copy of their ELD records on demand – either by printing it out or electronically transferring it.
  • Support one of two options for electronic data transfer:
    • Telematic type: using wireless web services or email
    • Local transfer type: using USB2.0 or Bluetooth
  • Display all the standardized data required by the rule, easily shared with safety officials on demand using either a screen display or a printout that includes:
    • A daily header.
    • A graph grid showing any driving duty status changes.
      • A printed graph grid must be at least 6 inches by 1.5 inches.
    • Detailed daily log data.
  • Require driver certification and annotations (written explanations) for any edits made to ELD records by the driver or the carrier. A driver must approve any edits made to the records.
  • Require drivers to certify their records at the end of every 24-hour period.
  • Include a user’s manual, instructions on how to handle malfunctions and keep records, as well as how to transfer ELD HOS records to safety officials. All these documents must be provided by the ELD provider.
  • Have a volume control or mute option for all the audio features.

ELDs aren’t required to track a driver’s performance, and don’t have to track things like how fast they’re going or how hard they’re breaking. However, ELDs can be a part of a larger fleet management system that does track those sorts of things.

What documents do I need in my vehicle to stay compliant?

As of December 18, 2017, any driver using an ELD must have an ELD information packet onboard that has:

  • A user’s manual outlining how to use the ELD.
  • An instruction sheet describing the ELD’s data transfer programs and step-by-step instructions outlining how to send records to safety officials.
  • An instruction sheet that explains how to report ELD malfunctions and properly keep alternative records until the problem is fixed.
  • Enough blank driver’s RODS graph grids to record duty status and other relevant information for at least 8 days.

We provide all of this on a simple cab card.


What types of supporting documents can be submitted to the FMCSA?

There are five types of supporting documents the FMCSA will accept:

  1. Documents showing where each trip starts and ends. Use things like schedules, bills of lading or itineraries.
  2. Dispatch or trip records.
  3. Expense receipts. Meals, lodging and fuel receipts count. Anything paid for when a driver is on-duty and not driving.
  4. Communication records from a fleet management system.
  5. Records showing the driver has been paid. Submit documents like payroll records or settlement sheets.

And each supporting document must have the:

  • Driver’s name (or a carrier-assigned identification number) on the document or on another document that lets the carrier link the first document to the driver. The vehicle unit number can also be used if that number can be linked to the driver.
  • Date.
  • Location (including the name of the nearest city, town, or village).
  • Time.

How long do carriers need to retain ELD documents?

Carriers are required to keep the ELD records and a back-up copy of it on a separate device for 6 months. FTS will store these documents as long as a customer is with us, unless the customer requests a purge.

Drivers have to submit RODS (records of duty status) and all their supporting documents to the carrier no later than 13 days after receiving them.

Which supporting documents do carriers need to keep?

The carrier must keep the first and last documents for the day along with six others. If a driver submits fewer than eight documents, the carrier is required to keep all of them.

If a driver has less than 8 documents that include all four of the necessary elements (name, date, location, and time), a document that has all the elements except “time” can be considered a supporting document.

Drivers using paper RODS (records of duty status) must keep toll receipts too, however they don’t count toward the eight-document cap. A reminder too that paper documents don’t need to be stored if they’ve been scanned and are available digitally.

Supporting documents can’t be limited to documents collected at the beginning and end of the workday. It’s an important part of enforcing the 60/70-hour rule. Supporting documents verify the proper duty statuses and help officials assess compliance.

How can you transfer data electronically using your ELD?

Drivers should also be prepared to show safety officials the ELD's display or logs printed directly from the ELD.

Our ELD solutions utilize the telematic type, allowing drivers to easily transfer their logs to safety officials via web services and email. And managers are able to send logs to the FMCSA by using the ELD Dashboard in IntelliHub®.

Are there certain supporting documents you can provide electronically?

Electronic mobile communications – which are any type of communication that was sent through a fleet management system - and payroll records can be sent in electronically.

While these aren’t something drivers generally have on them, dispatchers or managers can include them as part of a larger record. Anything on an electronic mobile communication record is counted as one supporting document per business day.

What should I do if drivers use multiple, incompatible ELDs to record their RODS?

Carriers and drivers are responsible for making sure that all RODS information can be reviewed by roadside safety officials. If the driver can’t share the data from one system to another, they will have to either print it out or manually enter it into the main ELD system.

When will an ELD automatically start to record a driving status?

ELDs automatically switch to driving mode once the vehicle is going at least 5 mph. The vehicle will register as stopped once the speed stays at zero mph for three seconds.

If the truck hasn’t been moving for five consecutive minutes when the driving duty status is on, the ELD prompts the driver to confirm driving status or enter the right one. If the driver doesn’t respond within a minute, the ELD switches duty status to on-duty not driving.

It’s important for drivers to log out of the ELD at the end of the day. If a driver forgets to do so and he moves his vehicle, the ELD will automatically log the vehicle's movement as on duty and driving, messing up his time cards.

Who must have an ELD account?

Drivers and owner-operators are required to have an account with their own identification number and password.

Carriers and owner-operators must have their own username and password for administrative duties, like setting up user accounts and managing driver logs.

Drivers should always make sure to log onto the ELD before the vehicle starts moving. If they don’t, the ELD will:

  • Automatically record any driving time and data under an unidentified driver profile.
  • Remind the driver to stop the vehicle and log into the ELD with an audible alert and pop-up on the screen.
  • Not allow the driver to do anything else on the device until they login.

Drivers should also review any unassigned driving time when logging in, and add their time to their own records, or add a note explaining that the unassigned hours aren’t theirs.

Who can make edits to ELD records?

Both drivers and carriers can edit an ELD record, but the drivers are the ones who have final say in approving changes. And some things are not editable by anyone, like shortening the duration of an auto driving status.

You can correct mistakes or add information, but if you edit a record, you must include a note explaining the reason for the edit. When a log is edited, the ELD stores the original log along with a record of who makes any corrections or edits and a timestamp of when those edits are made.

Who is exempt from the ELD rule?

Drivers who use the short-haul exceptions can keep using timecards, and aren’t required to keep RODS or use ELDs.

Some drivers aren’t required to use ELDs but must still use an Automatic On-Board Recording Device (AOBRD) or electronic logging software. They are:

  • Drivers who use no more than 8 days of paper RODS every 30 days.
  • Drivers using vehicles made before the year 2000.
  • Drivers who conduct drive-away-tow-away operations, where the vehicle being driven is the commodity, or a motor home or recreational trailer with at least one set of wheels on the road.

Everyone who is required to keep logs must be compliant by December 16, 2019.

You can install an ELD in any CMV, even if it's not required for that vehicle or your operation. If you do install one, it can be configured to show inspectors the ELD exception right on the device. You can also make a note on the logs that says you're exempt.

Carriers can also install ELDs in vehicles made before 2000, but the ELD must comply with the ELD rule’s technical specifications.

What type of agricultural exemptions are there?

Congress added agricultural exemptions to the ELD rule that include:

  • Covered farm vehicles that weigh 26,000 lbs or less.
  • Covered farm vehicles weighing 26,001  lbs or more if the vehicle is operated in the state it’s registered in, or across state lines within a 150 air-mile radius of the farm or ranch.
  • Drivers who transport agricultural commodities within a 150 air-mile radius of the farm or ranch. More info here.

Drivers going over state lines who have livestock or commercial bees onboard are exempt from the HOS 30-minute break requirement.

There are also certain times when drivers who aren’t currently transporting goods can log their drive time as personal conveyance, preventing that time from counting against their daily or weekly limits. For more details on the personal conveyance exemption, check out the FMCSA’s proposed guidelines.

What if a driver operates outside the air-mile radius and doesn’t qualify for a limited ELD exemption?

If a driver goes outside the farm’s designated air-mile radius and doesn’t qualify for the limited ELD exemption, there’s two ways to record their HOS on an ELD:

Option 1:

A driver can operate within the 150-air mile radius without logging into the ELD, and then login once they reach the radius limit. The drive time that takes place within the radius will be labeled as unidentified driving time on the ELD.

The driver rejects the unidentified driving time, and the carrier submits a note on the log explaining that the driving time is covered under an agriculture HOS exemption.

Option 2:

The driver can log on as soon as they’re on duty, and just identify the time they drove within the 150-air mile radius with an annotation on the ELD, stating that the vehicle was operating under an agriculture HOS exemption.

When a driver is required to use an ELD, the safety official will transfer and review the ELD data.

What is a “grandfathered” automatic onboard recording device (AOBRD)?


A “grandfathered” AOBRD is a device that carriers installed and used before the ELD rule compliance date in December 2017. As long as the device meets the requirements of 49 CFR 395.15, carriers can use their grandfathered AOBRDs until December 16, 2019. After that, everyone must use ELDs.

If your fleet has grandfathered AOBRDs, the FMCSA announced in March 2018 that they will allow you to continue installing AOBRDs into vehicles that are added to your fleet. This means you can now avoid having a mixed fleet of ELDs and AOBRDs. Just keep in mind that the newly installed hardware must be ELD-capable and you will need to upgrade all AOBRDs to ELDs by December 2019, regardless of when the AOBRDs were installed.

When do carriers and drivers using AOBRDs have to switch over to ELDs by?

Drivers who are not exempt from the ELD rule will need to be using an ELD by December 16, 2019. The ELDs must be installed before the deadline, and all of the appropriate staff must know how to use them by then. Drivers and carriers will also need to know how to display and transfer data to safety officials by the deadline.

Do drivers operating in Canada or Mexico need to use an ELD while driving through the U.S.?

Yes. Drivers from Canada or Mexico driving through the U.S. must use an ELD or grandfathered AOBRD.

Drivers from Canada and Mexico qualify for the same ELD exemptions as U.S. drivers. A driver is also exempt from the ELD rule if the U.S. destination is within a 100 air-mile radius of the driver’s normal reporting location in Mexico or Canada and the driver gets out of work after 12 hours.

How does the ELD rule affect personal conveyance?

The rules about personal conveyance haven’t changed, but the miles are now recorded.

If vehicles are allowed to be used for personal reasons, it’s up to the carrier to make sure drivers are trained and clearly understand the personal conveyance policy.

Before the driver hits the road for personal reasons, they must select the personal conveyance status in their ELD to track the miles.

When driving under personal conveyance, the ELD’s position reporting accuracy drops from a 1-mile radius to a 10-mile radius to ensure the privacy of the driver's exact location.

Does the ELD rule apply to rentals?

If you’re required to have an ELD, it doesn’t matter which vehicle you’re driving, according to Joe DeLorenzo, head of enforcement and compliance at FMCSA.

If you use a rented vehicle with an ELD system, make sure you have the current day and previous 7 days of logs on-hand for inspections. You can show the safety officer your phone or tablet if that's what you usually use for logging hours, or you can print out the records beforehand.

Keep in mind that under the ELD rule, drivers are required to keep an ELD manual and data transfer instruction sheet on-hand. So make sure you have the proper documentation in the rental.

There is a limited exemption for carriers that use a rented CMV for eight days or less. In this scenario, you aren’t required to use an ELD, regardless of what the vehicle is being used for. Check out the Federal Register for more details about this exemption.

What do I need to do with unassigned driver logs?

Drivers should review any unassigned driving time when they log into their ELDs. They’ll have to indicate whether the unassigned records belong to them or not.

Carriers should also review unassigned driving time and assign it to the right driver, or explain why the time isn’t assigned. Our ELD Dashboard makes this process simpler by suggesting drivers that might be responsible for unassigned logs.

Keep in mind, carriers are required to hold onto unidentified driving records for at least six months if no drivers accept them. 

Can co-drivers make entries when the vehicle is moving?

Yes, co-drivers can make entries and edits to their own records when they aren’t driving, even if the vehicle is moving. However, co-drivers can’t switch driving roles on the ELD while the vehicle is in motion.

What do I need to do during an inspection?

One of the biggest differences with the ELD rule is the ability for carriers and drivers to transfer data to safety officials. FMCSA officials say it makes the process faster and more accurate than inspectors deciphering handwritten logbooks.

During an inspection, drivers must provide:

  • Their hours-of-service for the last 7 or 8 days.
  • Supporting documents they have on hand.
  • Access to the unidentified driver profile using either the ELD display or a printout.

What happens if my ELD isn’t compliant?

If the FMCSA decides that the ELD in your vehicle isn’t compliant, you will have 8 days to replace it. That also goes for ELDs that may otherwise be compliant but need to be repaired, replaced or serviced.

If the non-compliance turns out to be a widespread issue in your fleet, the FMCSA will work with you to establish a reasonable timeframe to replace all of your non-compliant devices.

If this recently happened to you, get in touch with us right away and we’ll help get you back up and running with compliant ELDs as quickly as possible.

Can I contest an ELD violation?

Yes, you can contest ELD violations through DataQs.

With DataQs, you can request a review of Federal and State data issued by the FMCSA that you think may be incomplete or incorrect. The system automatically forwards your Request for Data Review (RDR) to the right FMCSA officer to look over, giving you the chance to protect your SMS score.

What type of behavior would qualify as HOS harassment?

The FMCSA says a driver can consider a carrier’s behavior “harassment” if a carrier knows, or should have known, its actions would force a driver to violate HOS rules. Carriers are prohibited from requiring drivers to drive when their ability to safely do so is impaired by things like fatigue or illness.

The ELD rule has provisions that prevent carriers from using the ELDs to harass drivers. ELDs are designed to only allow limited edits to the logs by both the driver and the carrier. And when changes are made to a log, the original, unedited log is always retained so the documents can be compared.

Drivers can file a written complaint with the FMCSA if they feel they are being harassed.

How do I file a harassment complaint?

If a carrier knows, or should have known, that its actions would force a driver to violate HOS rules, the FMCSA considers it harassment.

Drivers can file a harassment complaint by contacting the National Consumer Complaint Database or the FMCSA Division Administrator in that state they're employed in.

Information that must be submitted in writing includes:

  • The driver’s name, address, and telephone number.
  • The name and address of the motor carrier the driver feels is harassing them.
  • The facts that prove the harassment allegations, including;
    • How the ELD factored into the harassment.
    • The date when the incident happened.
    • How the carrier’s actions violated either 49 CFR 392.3 or 49 CFR 395.
  • The driver’s signature.

Drivers have 90 days to file a complaint after the event takes place.

Drivers, please remember that you are protected under FMCSA’s coercion rule and the Department of Labor’s whistleblower law, which prohibits carriers from retaliating against you for filing a complaint.

About the MAP-21 Law and ELD Rule

The ELD rule is part of phase two of the MAP-21 law. President Obama signed the Moving Ahead for Progress in the 21st Century Act (P.L. 112-141) into law on July 6, 2012 to provide more than $105 billion in funds to surface transportation programs.

The law created a streamlined program to reduce crashes, injuries and fatalities involving large trucks and buses by:

  • Raising the standards to get into the industry and operate in the United States.
  • Making sure companies and drivers meet the new standards by holding them accountable.
  • Forbidding high-risk drivers, vehicles and carriers from getting back on the road.

These measures built on previous highway, transit, bike and pedestrian policies enacted in 1991 by the Senior Bush administration.

The ELD rule is designed to make sure truckers comply with a federal hours-of-service rule that limits a driver’s workday. Drivers are not allowed to drive more than 11 hours a day within a 14-hour workday, and then must be off-duty for 10 hours.

The ELD rule:

  • Establishes standardized technical specifications to make sure ELDs are compliant.
  • Creates standard data displays and data transfer processes for easy sharing.
  • Helps prevent data from being tampered with and forbids harassing drivers.

The rule applies to carriers and drivers who must keep records of duty service (RODS). While there are some exemptions on who currently needs to use the ELDs, all drivers and carriers required to keep RODS must use a registered ELD by December 16, 2019.
