What do I need in my vehicle at all times to comply with FMCSA regulations on ELDs?

Beginning on December 18, 2017, drivers using ELD's must always have the following materials on hand in their vehicles:

1. A driver's instruction manual that shows how to operate the ELD
2. An instruction sheet describing how to transfer Hours of Service data from the ELD to an authorized safety official
3. An instruction sheet describing how backup reporting works in the case of ELD malfunctioning
4. At least 8 days' worth of blank driver’s records of duty status (RODS) graph-grids
