ELD Compliance Requirements: Who Needs One, What It Must Do, and What Happens If You Don't Have One
Running without a required ELD is not a paperwork technicality. It's an out-of-service violation. Here's exactly who is required to have an ELD, who is exempt, and what happens when officers find violations.
The ELD Mandate: What the Law Requires
The Electronic Logging Device mandate is codified under 49 CFR Part 395 Subpart B. It requires most commercial motor vehicle drivers who are currently required to prepare Records of Duty Status (RODS) to use a registered ELD to track their hours of service.
A compliant ELD must be registered on FMCSA's list of registered devices. Verify any device at eld.fmcsa.dot.gov.
Who Is Required to Use an ELD
If you drive a commercial motor vehicle in interstate commerce and are required to prepare RODS under 49 CFR § 395.8, you are required to use an ELD — unless a specific exemption applies to you.
This covers most for-hire drivers operating CMVs over 10,001 lbs GVWR in interstate commerce.
ELD Exemptions: Who Doesn't Have to Use One
There are several legitimate exemptions. Know them. Officers know them too.
- Short-haul exemption (100 air-mile radius): Drivers who operate within 100 air miles of their work reporting location, return to that location within 12 consecutive hours, and do not drive beyond 11 hours are exempt (49 CFR § 395.1(e)(1)).
- Short-haul exemption (non-CDL, 150 air-mile radius): Drivers who don't need a CDL, operate within 150 air miles of their reporting location, and return within 14 consecutive hours (49 CFR § 395.1(e)(2)).
- Driveaway-towaway operations: If you are driving a vehicle that is itself the commodity being delivered.
- Vehicles manufactured before model year 2000: CMVs with engines manufactured before model year 2000. The engine year is what matters, not the vehicle registration year.
- Drivers using RODS for 8 days or fewer in a 30-day period.
| Exemption | Key Requirement | Paper Logs Still Required? |
|---|---|---|
| 100 air-mile short-haul | Within 100 miles, returns in 12 hrs | No |
| 150 air-mile (non-CDL) | Within 150 miles, returns in 14 hrs | No |
| Pre-2000 engine | Engine (not vehicle) manufactured before 2000 | Yes |
| Driveaway-towaway | Vehicle being driven is the commodity | Yes |
| ≤8 days RODS in 30 days | Infrequent RODS requirement | Yes (on those days) |
What a Compliant ELD Must Do
Not every device called an “ELD” is actually compliant. The device must be registered with FMCSA and meet the technical standards in 49 CFR Part 395 Subpart B:
- Automatically records driving time when the CMV is in motion at more than 5 mph
- Synchronizes with the vehicle's engine (ECM/ECU) for odometer, speed, and engine hours
- Displays and transfers data — officers at roadside must be able to view the log data on the device screen or via a printout; data must be transferable via Bluetooth, USB, or FMCSA web services
- Detects malfunction — the device must alert the driver and carrier when it malfunctions
- Records all required data fields including location, driver identification, vehicle identification, carrier information, and duty status changes
If your device doesn't interface with the vehicle's ECM — it's not a compliant ELD.
ELD Malfunction: What You Must Do
ELDs will malfunction. When they do, you are required to:
- Note the malfunction — annotate your records and attempt to correct the issue
- Notify your motor carrier within 24 hours of the malfunction
- Keep paper logs — maintain handwritten RODS for the duration of the malfunction, up to 8 days while awaiting repair or replacement
- Reconstruct any missing records from the malfunction period using paper logs
What Happens If You're Caught Without a Required ELD
Running without a required ELD — or with a non-registered device — is a violation under 49 CFR Part 395. Depending on the severity, this can result in:
- A driver out-of-service order
- Fines — ELD violations can result in civil penalties up to several thousand dollars per violation
- CSA BASIC points in the HOS Compliance category — see CSA Scores Explained
For the specific HOS violations that most often lead to out-of-service orders, see HOS violations that get truckers shut down.
Common ELD Compliance Mistakes
- Using an unregistered device. Verify your device at eld.fmcsa.dot.gov before every new device purchase.
- Not knowing how to display logs to an officer. Officers will ask you to show them your logs on the ELD. Practice this. Know the screen.
- Ignoring malfunction alerts. When the ELD flags a malfunction, you have 24 hours to notify your carrier and 8 days to get it fixed.
- Not carrying the user manual. Federal regulations require you to carry the ELD manufacturer's user guide in the cab.
- Assuming the short-haul exemption applies when it doesn't. If you drive 102 air miles from your home base, you don't qualify for the 100-mile exemption for that day.
Frequently Asked Questions
Can I use my phone as an ELD?
Some FMCSA-registered ELD solutions use a smartphone app combined with a Bluetooth adapter that interfaces with the vehicle's ECM. The app itself is not the ELD — the combination of app plus ECM-connected hardware is. Verify the specific solution is on FMCSA's registered ELD list.
Do local/city truck drivers need an ELD?
Drivers operating exclusively intrastate may be subject to state-level HOS rules rather than federal rules. Some states have adopted the federal ELD mandate for intrastate operations; others have not. Check your state's specific requirements.
How do I know if my ELD is currently registered?
Go to eld.fmcsa.dot.gov and search for your device by manufacturer name or device name. If your device isn't listed, it is not compliant.
What's the penalty for a first ELD violation?
Penalties depend on the specific violation and whether it's a first offense. Driver out-of-service and civil penalties are both possible. See DOT fines and penalties for current penalty ranges.
