Unless specifically exempt, CMV drivers must keep daily logs of their time spent off-duty, driving, and on-duty (not driving), and carriers must retain copies of those logs and supporting documents (e.g., fuel records) for at least 6 months. In many cases, drivers must keep these logs electronically using ELDs; however, in cases where drivers are not ordinarily subject to the ELD requirement but must otherwise keep paper logs, this document will serve that purpose.
