HOS refers to the Hours of Service CMV drivers are required to log. Drivers are required to keep track of their driving hours and breaks.


In the past, CMV drivers utilized paper logs to keep track of their driving hours. With the ELD Mandate, CMV drivers are required to keep track of their Hours of Service through ELDs (Electronic Logging Devices) that produce electronic logs. These ELDs are required to automatically record drive time.
