Final answer:
A FedEx driver's road test should be conducted using a vehicle that matches what they will operate on the job, from standard delivery vans to larger cargo trucks, depending on their expected duties.
Step-by-step explanation:
When conducting a road test for a driver at FedEx, the size of the vehicle used should appropriately match the class of vehicle that the driver is expected to operate as part of their job duties. For drivers handling the delivery of small to medium packages, a standard FedEx delivery truck or van is often used. However, for drivers expected to drive larger vehicles, such as cargo trucks, the road test should be conducted using a vehicle of similar size and handling characteristics to those they will be operating in their role to ensure they can manage the vehicle safely and efficiently.
