Who is responsible for monitoring the competency of drivers according to Army Regulation 600-55?

Monitoring the competency of drivers is primarily the responsibility of the designated unit trainer or operations noncommissioned officer (NCO). This individual plays a crucial role in ensuring that soldiers meet the necessary standards before they are allowed to operate military vehicles. They are tasked with administering the training and evaluation processes that assess driver proficiency. This includes conducting assessments, providing necessary training sessions, and ensuring compliance with the regulations established in AR 600-55.

While the unit commander is responsible for overall unit readiness and mission accomplishment, and the safety officer focuses on safety protocols, the direct oversight of driver competency falls specifically to the designated unit trainer or operations NCO. They are the ones with the relevant expertise and day-to-day involvement with driver training, making them the key personnel for this responsibility.
