Who periodically assesses the performance of drivers?

The selection of supervisors as the answer highlights their critical role in the ongoing assessment of driver performance within the Army. Supervisors are directly involved in overseeing the day-to-day operations and training of personnel. They have the responsibility to evaluate the capabilities, skills, and compliance of drivers with established safety and operational standards. By conducting regular assessments, supervisors can identify any issues or areas for improvement and ensure that drivers stay proficient in their skills. Their direct oversight enables them to provide immediate feedback and coaching, which is essential for maintaining high performance and safety standards in driving tasks.
