Which of the following is NOT a clerical duty expected of the driver?

Typing invoices is not typically considered a clerical duty expected of the driver. The primary responsibilities of a driver usually focus on transporting goods, ensuring vehicle safety, and interacting with customers. While drivers do need to handle certain administrative tasks, such as getting required signatures and filling out or listing services on invoices, these tasks often do not require skill in typing. Therefore, typing invoices is generally outside the scope of a driver's typical duties, which might instead involve more manual record-keeping or using a simple electronic device where typing is not the primary focus.
