Final answer:
When using a commercial vehicle for personal use, the driver must record total mileage driven and business-related stops in her logbook.
Step-by-step explanation:
When using a commercial vehicle for personal use, the driver must record total mileage driven in her logbook. This includes both business-related mileage and personal use mileage. The logbook serves as a record of all the miles driven, which helps the driver keep track of the vehicle's usage and any associated expenses.
While recording the total mileage driven is important, it's also crucial to record any business-related stops made during the trip. This helps the driver maintain an accurate record of the purpose and duration of each stop.
In her logbook, the driver does not need to record hours of sleep or personal use details. These aspects are not relevant to the purpose of the logbook, which primarily focuses on documenting the mileage and business-related stops in a commercial vehicle.
