Which document should drivers maintain to verify their hours of service compliance?

To ensure compliance with hours of service regulations, drivers must maintain a logbook or utilize an electronic logging device (ELD). These tools are specifically designed to record driving hours, rest breaks, and overall duty status, which are crucial for verifying compliance with federal regulations governing the amount of time drivers can operate a commercial motor vehicle.

Keeping accurate records via a logbook or ELD helps drivers and regulatory authorities track whether the drivers are adhering to mandated hours of service limits. This is essential for promoting road safety and preventing fatigue-related incidents.

The other options, while related to vehicle operation and safety, do not serve the specific function of tracking hours of service. A maintenance schedule focuses on vehicle upkeep and repairs, a compliance certificate serves as proof that a driver or a vehicle meets certain regulatory requirements, and an inspection report documents the condition of the vehicle but does not relate to the driving hours of the operator. Thus, the logbook or ELD is the critical document for ensuring compliance with hours of service regulations.
