Roadside Manual & Inspection Guide
Roadside Inspection and Malfunction Instructions
If the log data cannot be transmitted due connectivity or technical issues you are still compliant as long as you are able to show your logs on your device. Below is the Q&A guidance provided by the FMCSA.
Q7. Would an electronic logging device (ELD) be non-compliant with the ELD rule if the data cannot be sent electronically to an authorized safety official at roadside?
A7. No. If the electronic means for transferring data is unavailable or fails, the driver can still be compliant by showing either a printout or the actual ELD display of their RODS.
