Which publication addresses Motor Vehicle Traffic supervision?

The publication that addresses Motor Vehicle Traffic supervision is indeed the correct choice. AR 190-5 outlines the policies and procedures for the supervision of motor vehicle traffic, focusing on safety, enforcement, and the management of traffic-related activities. This regulation is essential for maintaining order on roadways, ensuring that vehicle operators comply with established rules and guidelines, and ultimately contributing to overall traffic safety.

The other publications listed serve different purposes: DA Pam 611-21 pertains to military occupational specialties and occupational classifications; AR 600-55 deals with the Army Driver and Operator Standardization Program, including driver training, licensing, and qualification; and DA 750 provides guidance on the Army's property accountability and maintenance. While relevant to their respective areas, they do not specifically address the supervision of motor vehicle traffic as AR 190-5 does.
