The document DOT officers ask for at roadside. Download the ELD Hub cab card and driver manual for your device — PT-30 or IOSiX, iOS or Android — and keep it in the truck.
Match your ELD hardware and driver phone. Print a paper copy for the glovebox, keep the PDF on the driver's device as backup.
An ELD cab card is a 1–2 page reference that lives in the truck. It exists for one reason: a DOT officer walks up at a roadside inspection, asks how to pull the last 8 days of hours-of-service data off the ELD, and the driver hands them the card.
FMCSA rules require every driver operating with an ELD to carry an instruction sheet covering data transfer, malfunction procedures, and how to switch to paper logs if the device fails. The ELD Hub driver manuals below include all of that.
Roadside inspections
DOT officers use the cab card to verify your ELD is registered and to pull HOS data.
Malfunction procedures
If the ELD fails, the manual tells drivers exactly how to revert to paper logs — legally.
In the truck, always
Paper copy in the glovebox, PDF on the driver's phone. Both count under current FMCSA guidance.
An ELD cab card is a printed document (usually 1–2 pages) that drivers keep in the truck for roadside inspections. It shows the DOT officer how to operate the ELD, transfer HOS data, and switch to paper logs if the device malfunctions.
Officers can ask for: your HOS logs (transferred via email or web services from the ELD), a driver's manual for the ELD, instructions on how to transfer data, and paper log-book forms in case the ELD fails. The cab card / driver manual covers most of those requirements in one document.
FMCSA requires the documents to be 'in the vehicle' — the current guidance accepts either paper or an accessible digital copy on the same device running the ELD. To be safe, most fleets print a paper copy and keep the PDF on the driver's phone as backup.
The cab card is a subset of the user manual — the pages a DOT officer needs at a roadside stop (data transfer instructions, malfunction procedures, driver interface). Some providers hand out both; others combine them. The ELD Hub driver manuals include all the required cab-card content.
It's a violation. Depending on the officer and jurisdiction, you may be cited or logged as out of compliance. It's not usually out-of-service, but it hurts your CSA score.
Match your hardware and phone. If your fleet uses PT-30 devices and drivers run iPhones, download 'PT-30 ELD — iOS.' If you're on IOSiX and Android, download 'IOSiX ELD — Android.' If you mix hardware, keep all four PDFs on the driver's phone.
FMCSA-registered ELD at $15 per truck per month. No contract. Works with PT-30 or IOSiX hardware you may already own.
