An ELD takes engine power status, motion, miles and engine hours straight from the truck, and that record is the driver’s log. Any driver in interstate commerce who has to keep a record of duty status has to use one. The people who don’t: short-haul drivers who stay within 150 air miles and get back within 14 hours, drivers who need a log on 8 or fewer days in any 30, driveaway-towaway drivers, and trucks or engines built before model year 2000. FMCSA doesn’t endorse any device; providers self-certify, and when a device fails the specs FMCSA revokes it and gives carriers 60 days to swap it out. Underwriters ask about your ELD because the hours-of-service record it produces is the cleanest evidence of how your drivers actually run.
What an ELD is and who has to use one
An ELD connects to the truck’s engine control module and automatically captures engine power status, vehicle motion, miles driven and engine hours. The driver still selects off duty, sleeper berth and on-duty not driving (§395.24(b)); driving time is set by the device whenever the vehicle is in motion (Appendix A, 4.4.1.1). Under 49 CFR 395.8(a)(1), a motor carrier has had to install an ELD and require its drivers to use it since December 18, 2017, for every driver who must keep a record of duty status, and §390.3 applies it to interstate commerce.
The device has to be on FMCSA’s registered list (§395.22(a)), and that is the carrier’s job, not the driver’s.
Who doesn’t need one
- Short-haul drivers. Under §395.1(e)(1), a driver who stays within a 150 air-mile radius of the normal work reporting location, returns there and is released within 14 consecutive hours, and gets 10 consecutive hours off between shifts keeps no record of duty status, so no ELD. The carrier keeps time records instead (report time, hours on duty, release time and, for first-time or intermittent drivers, the preceding 7 days’ total) for 6 months.
- 8 days in any 30. A driver who needs a log on no more than 8 days in any 30 may keep it on paper (§395.8(a)(1)(ii)(A)).
- Driveaway-towaway. When the vehicle being driven is itself the shipment, or the vehicle transported is a motor home or RV trailer.
- Pre-2000 trucks. A vehicle manufactured before model year 2000 by the VIN on its registration. FMCSA’s FAQ extends this to pre-2000 engines in glider kits or engine swaps; the driver needn’t carry proof, but the carrier keeps the engine-change paperwork.
Exempt doesn’t mean unregulated: the short-haul driver still works inside the 14-hour and 10-hour-off limits.
The hours it is tracking
The ELD exists to enforce 49 CFR 395.3, the driving limits for property-carrying drivers:
- 10 hours off before driving.
- 14-hour window. No driving after 14 consecutive hours from coming on duty.
- 11 hours driving inside that window.
- 30-minute break. No driving once 8 cumulative hours of driving have passed without a consecutive 30-minute interruption in driving status; thirty straight minutes in any non-driving status counts.
- 60 hours in 7 days or 70 in 8, depending on whether the carrier runs every day, with a reset after 34 or more consecutive hours off.
An ELD isn’t required to flag violations, but every duty-status change is recorded with date, time, vehicle miles and engine hours (Appendix A, 4.5.1.1), so a stretched 14-hour window sits in the data for whoever pulls it.
The registered list and revoked devices
FMCSA doesn’t endorse any ELD. Providers self-certify that a device meets Appendix A to Subpart B of Part 395 and register it; the list page says as much.
FMCSA’s three most recent batches pulled 12 devices on May 20, 2026, 10 on July 9 and 5 on August 6, the last five for failing the Appendix A minimums. When I pulled the revoked list in early October 2026 it ran to 387 entries, 102 dated 2026: 56 FMCSA revocations and 46 the providers withdrew themselves.
The August notice spells out the drill: stop using the device, go to paper logs or logging software, and replace it from the registered list within 60 days. After the deadline (October 6, 2026 for that batch) a driver still on it is cited under §395.8(a)(1) for no record of duty status and placed out of service under the CVSA criteria. Check your device against the list at every renewal.
What inspectors ask for
Under §395.24(d), a driver must produce and transfer the ELD records when an authorized safety official asks. The official picks from the methods the device certifies (Appendix A, 4.9.1): web services or email for telematics devices, USB 2.0 or Bluetooth for local ones. If the transfer fails, the backup is a screen or printout readable without getting into the cab. The file covers the current 24-hour period and the previous 7 consecutive days.
§395.22(h) lists what has to be in the truck: the user’s manual, an instruction sheet for the data transfer, an instruction sheet for malfunctions, and blank log grids for at least 8 days.
If the device malfunctions, the driver gives the carrier written notice within 24 hours, reconstructs the current day and previous 7 days on paper, and stays on paper until it is fixed; the carrier has 8 days to correct it. A driver who should have an ELD and doesn’t is placed out of service for 10 hours (8 for a passenger carrier).
Why I ask about your ELD
Underwriters ask for a plain reason. FMCSA’s Safety Measurement System sorts roadside inspection results into seven categories, the BASICs; one is Hours-of-Service Compliance, violations of the record-of-duty-status rules as they bear on hours limits and driver fatigue. Its own examples: a property-carrying driver driving more than 11 hours, logs not kept for 6 months. Since the FAST Act a property carrier’s SMS results are not on public display; the carrier logs in to see them, which is why an underwriter asks you for them.
Expect to be asked which ELD you run and whether it is on the registered list, how many drivers use the short-haul exception and how you document their time, and whether anyone has had a log-related out-of-service order. Clean answers make an account easy to place. What a trucking policy is built to do, what the new entrant safety audit covers, and keep the registered-list check on your compliance calendar.
Common questions
Does a short-haul driver need an ELD?
No, as long as the driver stays within a 150 air-mile radius, returns to the work reporting location and is released within 14 consecutive hours, and gets 10 consecutive hours off between shifts. The carrier keeps time records in place of logs and holds them for six months.
My truck is a 2003 glider with a 1998 engine. Do I need an ELD?
FMCSA’s FAQ says a pre-2000 engine is accepted even when the VIN shows a later model year. The driver doesn’t have to carry proof, but the carrier has to keep the engine-change records at its principal place of business.
What happens if FMCSA revokes my ELD?
Stop using it, go to paper logs or logging software, and replace it with a device from the registered list within 60 days of the notice. After the deadline, a driver still using it is cited for no record of duty status and placed out of service.
What does an inspector ask for at roadside?
A transfer of your records by web services, email, USB or Bluetooth, and if that fails, the display or a printout. Keep the user’s manual, the two instruction sheets and at least 8 days of blank logs in the cab.
What do underwriters ask about ELDs?
Which device you use and whether it is on FMCSA’s registered list, which drivers run under the short-haul exception, and whether you have had log-related violations or out-of-service orders. Hours-of-Service Compliance is one of the seven BASICs in FMCSA’s Safety Measurement System, and a property carrier’s results are not on public display, so the underwriter has to ask you.
