What action must you take when driving a vehicle within sight or hearing range of a colors ceremony?

When you are driving a vehicle within sight or hearing range of a colors ceremony, the appropriate action is to stop the vehicle and remain seated at attention. This practice is rooted in military customs and courtesies, as the colors ceremony, which involves the presentation of the national flag, is a solemn event that signifies respect for the flag and what it represents. By stopping and paying attention, you show reverence and honor to the ceremony and the service members participating in it. This adherence to protocol reinforces dignity and respect for the traditions of the military and acknowledges the significance of the moment for those present.
