Which of these is the only element which it is not compulsory to include on your daily log?

The number on your driver's license is not a compulsory element to include on your daily log. Typically, daily logs are designed to record essential information related to driving activities, such as details that monitor compliance with regulations around hours of service, vehicle inspections, and duty status changes.

Including the odometer reading at the start of the day is important for tracking mileage and ensuring compliance with driving limits. Documenting the location where the duty status has changed is also crucial, as it helps maintain accurate records for safety and regulatory purposes. Similarly, noting the number plates of all buses driven helps in identifying vehicles used during the day, which is significant for operational tracking.

In contrast, the specific number of your driver's license does not directly affect the operational or safety parameters of the log, making it the element that is not required to be documented daily.
