Choosing the best ELD for trucks looks easy. Most ELD websites say the same thing: compliant, easy, cheap. Then you sign. Later you learn about the two-year contract, the $150 device you must send back, or the support line that closes at 5 p.m. And you need help at a weigh station at 11 p.m.
This guide shows how to choose the best ELD for trucks you run, one truck or a whole fleet, so you choose once and don’t worry about it later. If you are new to ELDs, start with our ELD for trucks page. It is the checklist we use ourselves: what to check, what to ask, and the real cost after two years.
The best ELD for trucks: the short version
- Check the FMCSA list yourself. The device must be on the registered list and not on the revoked list. How to check.
- Make sure it fits your truck. The cable has to match your diagnostic port: 9-pin, 6-pin, OBD-II, Volvo/Mack or RP1226. See which cable your truck needs.
- Add up two years, not one month. Device + monthly fee + activation + what it costs to leave.
- Read the contract before the features. Automatic renewal and fees to leave early cost more than any feature saves.
- Call support at night before you buy. Inspections don’t happen during office hours.
1. Check the FMCSA registered list, and the revoked list
FMCSA does not approve or certify ELDs, even though many websites say it does. Each provider tests its own device, says it meets the rules, and registers it with FMCSA. FMCSA keeps the list. It removes devices that do not meet the rules.
So “FMCSA approved” on a website does not prove anything. Check it yourself. It takes two minutes:
- Open the FMCSA registered ELD list.
- Search for the provider’s name or the device model.
- Match the exact model and software version to what the salesperson is offering you.
- Then open the revoked devices list and make sure it isn’t there.
Why the revoked list matters: when FMCSA revokes a device, every carrier using it gets up to 60 days to switch to a registered one. After that deadline, a driver still on the old device counts as having no ELD and can be put out of service. If you have a contract for that device, you may pay for two ELDs at the same time. Providers with a long, clean record on the list are the safer choice.
2. Make sure the device fits your truck
An ELD plugs into your truck’s diagnostic port, and the cable has to match that port. Look under the dash on the driver’s side, near the steering column. The shape of the port tells you what you need:
| Port | Usually found in | Cable you need |
|---|---|---|
| Round 9-pin | Most heavy trucks built in the last 20 years | 9-pin ELD cable |
| Round 6-pin | Older heavy trucks | 6-pin ELD cable |
| Flat 16-pin OBD-II | Pickups, box trucks, many medium-duty trucks | OBD-II ELD cable |
| 16-pin in a Volvo or Mack | Volvo and Mack trucks | Volvo/Mack 16-pin cable |
| RP1226 | 2025 and newer Volvo trucks | RP1226 cable |
Some providers include the cable. Others charge extra for it. If you have different trucks, ask if you can change the cable later without buying a new device. Not sure which port your truck has? A good provider asks for the year, make and model and tells you before you order. See which cable your truck needs.
3. Decide where the logs live: phone, tablet or a built-in screen
Most ELDs today work with your own phone or tablet. A small box goes in the port. It connects to an app on the phone or tablet by Bluetooth. This is the cheapest way, and it is legal. Keep in mind:
- While driving, a phone or tablet used as the ELD screen must be mounted in a fixed position, not loose on the seat (49 CFR 395.22(g)).
- A tablet is easier for an inspector to read. Its battery also lasts longer. Many owner-operators start with a phone and buy a cheap tablet later.
Some ELDs come with their own screen. They cost more, and you can only use that company’s hardware. This matters if you want to change providers later.
4. Add up the real cost over two years
The monthly price is only one part of the cost. What you really pay is:
device + cable + (monthly fee × months) + activation fee + what it costs to leave early
Here are three common types of pricing for one truck over 24 months. These are example numbers to show the math. They are not prices from a real provider:
| Setup | Device | Monthly | 24-month total | Watch out |
|---|---|---|---|---|
| Cheap monthly, buy the device | $149 | $20 | $629 | Basic logs only; GPS or IFTA often cost extra |
| “Free” device on a contract | $0 | $30 | $720 | Early exit usually means paying the rest of the contract |
| Leased device, 3-year term | $0 upfront | $35 | $840 (and a third year to go) | Device goes back when you leave; you start over |
The lowest monthly fee is not always the cheapest ELD. Ask every provider for the same four numbers in writing: device price, monthly fee, activation fee and early termination fee (what it costs to leave the contract early). Then add them up for the time you plan to stay. We compared real published prices in 5 best ELD providers compared.
5. Read the contract before you read the features
Most ELD problems come from the contract, not the device. Warning signs:
- Automatic renewal that signs you up for another one to three years.
- A rented device that you must send back, often with a fee if it is late or damaged.
- Activation or setup fees for each truck that are not on the price page.
- Features that come only with a more expensive plan, like IFTA miles or GPS history.
- A price that changes between the phone call and the contract.
A contract is not always bad. A one-year contract with a free device can be a fair deal. Just know exactly what it costs to leave early.
6. Make sure it handles a roadside inspection
This is where a weak ELD causes trouble. During an inspection, the driver must show the logs on the screen and send them to the officer. Before you buy, ask the provider to show you how it works, and try it yourself:
- How does the driver open the inspection screen? It should take one or two taps.
- How are logs sent to the officer? Most devices transfer through FMCSA’s web service or by email.
- Do you get the ELD information packet the rules require in the truck: the user manual, data transfer instructions, malfunction instructions and blank paper logs for at least 8 days (49 CFR 395.22(h))?
7. Test support before you need it
If the ELD stops working at 2 a.m., you need a real person to help. Before you sign, call support late in the evening or on a weekend. See who answers and how long it takes. Ask if they speak your drivers’ language. It costs nothing and tells you a lot.
8. Pay for the extras you’ll actually use
Besides hours of service, these extras save owner-operators and fleets real time or money:
- IFTA miles by state. If you drive in more than one state, the ELD counts miles in each state for you. Your quarterly IFTA report takes minutes, not hours.
- GPS tracking. Useful if you have more than one truck, or if customers ask where their load is.
- Electronic DVIR. Do pre-trip and post-trip inspections on the phone, not on paper.
- Dash cams. Good for fleets and for proving what happened in an accident. They usually cost extra each month for each camera. Skip them if you will not watch the video.
What users complain about most in ELD reviews
We read about 120 recent user reviews of five well-known ELDs. Five problems came up again and again, whatever the brand. Here is what to check before you buy, so they don’t happen to you:
| Common complaint | What to check before you buy |
|---|---|
| Support is slow or hard to reach | Call support at night or on a weekend. Ask if they speak your drivers’ language. |
| The device disconnects from the phone | Ask how the device reconnects, and test it in your truck during a trial. |
| Violations that look wrong, or logs you can’t fix | Ask how drivers request edits and whether the app warns before a driving limit. |
| The app changes or breaks after updates | Ask how often they update and whether drivers are warned before changes. |
| Hard to cancel or get a refund | Read the renewal and early-exit parts of the contract before you sign. |
Best ELD for trucks: owner-operator vs. fleet
| Owner-operator (1 truck) | Fleet (2 trucks or more) | |
|---|---|---|
| Top priority | Low total cost, no long contract | Fleet view: where every truck is and how many hours each driver has |
| Must have | Easy app, quick inspection transfer, IFTA miles | Driver log review, alerts when a truck moves with no driver logged in, GPS |
| Nice to have | Tablet support, dash cam later | Dash cams, link to your TMS and dispatch |
| Watch out for | Leased devices you can’t keep | Per-truck activation fees that multiply |
10 questions to ask any ELD provider
Copy these questions into an email. Send the same list to every provider you compare:
- What’s the exact device model, and where is it on the FMCSA registered list?
- Has any of your devices ever been revoked? What happened to your customers?
- What does the device cost, and do I own it or lease it?
- Which cable fits my truck (year, make, model), and is it included?
- What’s the monthly fee, and which features are included at that price?
- Is there an activation, setup or shipping fee?
- How long is the contract, does it auto-renew, and what does leaving early cost?
- What are your support hours, and can I reach a person at night?
- How does the driver transfer logs during a roadside inspection?
- Can I try it in my truck before I commit?
Do you even need an ELD?
Most drivers who cross state lines and keep logs need one. The main exceptions (49 CFR 395.8):
- Drivers who keep paper logs no more than 8 days in any 30-day period.
- Trucks with an engine older than model year 2000.
- Drivers using the short-haul exception, who don’t need logs at all.
- Driveaway-towaway operations where the vehicle being driven is the cargo.
If you are not sure you have an exception, use an ELD. Our post on ELD compliance guide covers the latest rules.
What if your ELD stops working?
ELDs do break sometimes. The rules say what to do (49 CFR 395.34). The driver notes the malfunction, tells the carrier within 24 hours and switches to paper logs, rebuilding the current day and the past 7 days on paper unless the ELD can still show them. The carrier then has 8 days to repair or replace the ELD. This is another reason to choose a provider whose support answers the phone.
Where TenTrucks fits
We built the TenTrucks ELD with this checklist in mind. It runs on the Pacific Track PT30 or PT40 device, which plugs into any of the five ports above and pairs with the driver’s phone or tablet. Service is $29 per truck per month. On a 1-year plan, the device and the cable are free. IFTA miles by state, GPS tracking and 24/7 support are included. It works for owner-operators and fleets of any size, and it connects to the TenTrucks TMS, so loads, dispatch and logs are in one place. See ELD devices and cables or ELD pricing.
On top of the ELD, you also get:
- AI that reads your load documents. Send a rate confirmation and the load is created for you.
- Your own hours rules. Custom duty cycles for fleets with state or industry exceptions.
- Not only trucking. It works for construction, field service, oil and gas, agriculture, utilities and other fleets.
- Settings that fit your fleet. A modern app you can set up the way you work.
- Something missing? Tell us, and we can build a custom feature for your fleet.
FAQ
What is the best ELD for owner-operators?
The best one is on the FMCSA registered list, fits your truck’s port, and costs the least for the time you will use it. It also has a contract you can leave. For most owner-operators that’s a plug-in device with a phone or tablet app, a monthly fee of about $19 to $35 and no lease. TenTrucks fits this: $29 a month with GPS, IFTA and 24/7 support included, and the device and cable free on a 1-year plan.
Is a cheaper ELD less compliant?
No. A registered device meets the same rules at any price. Cheap and expensive ELDs usually differ in extras, support and contract terms.
Can I use my phone as an ELD?
Yes, as the screen. The phone alone can’t read the engine, so you still need a device in the diagnostic port. While driving, the phone must be in a mount. The TenTrucks ELD works with a phone or a tablet.
How much should an ELD cost?
Published plans run about $19 to $35 per truck per month. Devices range from free with a plan to about $150. Compare the two-year total, not the monthly price. TenTrucks is $29 per truck per month, with the device and cable free on a 1-year plan.
Can I switch ELD providers?
Yes, when your contract allows it. First save your log records (carriers must keep them for 6 months). Then install the new device. Make sure drivers know the new inspection steps before you turn off the old one.
