What is the main responsibility of the dispatcher regarding vehicle usage?

The main responsibility of the dispatcher concerning vehicle usage is to determine vehicle authorization for use. This involves ensuring that the individuals requesting to use the vehicles have the appropriate permissions and that the purpose of the vehicle use aligns with organizational policies and regulations. An essential part of effective vehicle management is prioritizing safety and compliance, making sure that only authorized personnel are allowed to operate the vehicles.

The other options, while important in the overall management of the vehicle fleet, do not fall squarely within the dispatcher’s primary role. Washing vehicles, maintaining fuel levels, and scheduling regular maintenance are typically responsibilities managed by other personnel or departments. These tasks are critical for the operational efficiency and upkeep of vehicles but do not pertain directly to the dispatcher's core duty of overseeing who can use the vehicles and for what purpose.
