Plug in. Log in. Drive.Hours logged the way FMCSA wants them.

T42 ELD is the logging device built by Trucking42 for the owner-operators and small fleets we dispatch every day. One tap sends your logs to the officer. Nobody — not you, not your carrier, not us — can erase driving time.

Works with

Freightliner, Volvo, Kenworth, Peterbilt, International, Mack and more. PT30, PT40 and IOSiX gateways. 9-pin, 6-pin and 16-pin diagnostic ports. Android and iOS.

How it works

Up and running before your coffee gets cold

No installer, no wiring. The gateway plugs into the diagnostic port; the app does the rest.

    1Plug in

    Plug in the gateway

    Engine off. The port is under the dashboard, by your left knee: 9-pin on most trucks, 16-pin on Volvo and Mack, 6-pin on older trucks. IOSiX plugs straight in — twist to lock.

    Start the engine

    Wait for the light. PT30 and PT40 glow green and stay steady. IOSiX blinks green and blue. That means the gateway reads your engine.

  3. 3Connect

    Log in and tap your ELD

    Android or iOS. Log in with your own Driver ID, then tap your gateway's name in Connect ELD — it is on the sticker, like PT30_5DE3. The app pairs itself; no Bluetooth settings to dig through.

  4. 4Drive

    Drive — logging is automatic

    Driving starts on its own when the truck moves. Change status when you stop, certify your day with one tap, and show or send your logs when an officer asks.

Features

Made for the driver's seat, not the back office

Hours of service

Your hours at a glance

Drive left, shift, cycle and break on one screen. The timeline shows when to take your 30 and when you must stop — before you plan the next load, not after.

  • Yellow means running low, red means stop
  • 8-day recap and violation check
  • Adverse-conditions switch adds up to 2 hours when the weather turns
Roadside inspection

Roadside inspection in 30 seconds

Tap DOT inspection, pick Web service or Email, tap Send. The officer gets today plus the previous 7 days in the standard FMCSA file. No signal? Hand over the tablet in Inspection Mode — nothing on that screen can be changed.

  • FMCSA Option 1: Web services and Email
  • Instruction sheets built into the app for the officer
  • Printable blank paper logs for malfunction days
Tamper-proof

Logs you can trust — because nobody can rewrite them

Driving recorded by the truck is locked. Edits create a new entry and keep the original with your note. Your carrier can suggest a fix; only you can accept it. Every back-office action is written to an audit log we cannot edit.

  • No "fresh hours overnight" — by design
  • Unidentified driving is shown to you first, not hidden
  • Driver license data encrypted at rest
Certify

Sign your day in one tap

The bell reminds you. The app shows your on-duty, driving and miles, the exact FMCSA certification statement, and two buttons. Changed something later? It asks you to sign again.

  • Reminders at log-in and log-out
  • Team drivers: both log in, switch seats only when stopped
  • Personal conveyance and yard moves, if your carrier allows them
Registration status

T42 ELD is waiting for FMCSA registration

We have built and tested T42 ELD to 49 CFR Part 395, Appendix A, and submitted it to the Federal Motor Carrier Safety Administration. Until FMCSA adds it to the Registered ELD list, T42 ELD must not be used as your ELD for hours-of-service compliance (49 CFR 395.22(a)). We will publish the result here and email everyone on the early-access list the same day.

FAQ

Questions drivers ask us

Still have a question?

Call the 24/7 roadside line or message us on WhatsApp — we will also check whether your truck is ELD-exempt.

+1 (305) 399-8553
Can I use T42 ELD now?

Not yet as your official ELD. T42 ELD has been submitted to FMCSA and registration is pending. Until it appears on the FMCSA Registered ELD list, keep using your current registered ELD. Join early access and we will email you the day it is listed, with the ELD Identifier.

Does it work with my truck?

Any model-year-2000-or-newer truck with a 9-pin, 6-pin or OBD-II diagnostic port: Freightliner, Volvo, Kenworth, Peterbilt, International, Mack and more. Older engines without an ECM may be exempt from the ELD rule — call us and we will check.

Can my dispatcher change my logs?

No. Your carrier can propose a correction with a reason; it stays as a proposal until you accept or reject it in the app. Driving time recorded by the truck cannot be shortened by anyone, including Trucking42.

What happens if the ELD breaks?

A red M appears on screen with a letter code. Tell your company in writing within 24 hours, switch to paper logs for today and the previous 7 days, and your company has 8 days to fix or replace it. The exact steps are on page 12 of the manual and inside the app.

Can I switch from another ELD?

Yes. Your old logs stay with your old provider for the required 6 months; we help you export them. Most drivers switch in one afternoon: order the gateway, install the app, log in.

Do I need to carry the printed manual?

Not since July 2026. Keep the two one-page sheets (how to send logs, what to do on malfunction) and blank paper logs for 8 days. All of them are in the app under DOT inspection → ELD documents.
