What procedure should be followed if multiple, incompatible electronic logging devices (ELDs) are used to record a driver’s record of duty status (RODS)?

The motor carrier and the driver are responsible for ensuring that all of the RODS information required by the HOS rules is available for review by authorized safety officials at the roadside. If the driver uses multiple ELDs that are not compatible (e.g., the data file from one system cannot be uploaded into the other system), the driver must either manually enter the missing duty status information or provide a printout from the other system(s) so that an accurate accounting of the duty status for the current and previous seven days is available for the authorized safety official.
