During colors, vehicles within sight or hearing of colors shall take what action?

During colors, vehicles within sight or hearing of the ceremony are required to stop as a sign of respect for the national colors. This protocol reflects the importance of rendering honors during the hoisting or lowering of the flag, which is a ceremonial activity that symbolizes patriotism and recognition of military and national service. Stopping allows for a moment of reflection and shows adherence to military customs and courtesies.

While proceeding cautiously, using sirens, or slowing down may all seem like respectful actions, they do not convey the same level of honor and reverence as stopping does. The act of stopping ensures that attention is fully dedicated to the ceremony, reinforcing the values of discipline and respect expected in military culture.
