What must vehicles on military bases do when the national anthem is played?

When the national anthem is played on military bases, vehicles are required to stop. This action is a sign of respect for the anthem and what it represents. Stopping is a way to honor the flag, the nation, and the sacrifices made for freedom and rights guaranteed by the United States. It also demonstrates proper military customs and courtesies, reinforcing discipline and respect within the military environment.

Vehicles continuing to drive or sounding their horns would show a lack of respect for this ceremonial moment. Saluting is reserved for personnel who are in uniform, and while it is also a sign of respect, it applies to individuals rather than vehicles. Therefore, stopping ensures that all can participate in honoring the national anthem appropriately while fostering a culture of respect throughout the base.
