When the flag is passing in parade, being hoisted or lowered, all present should face it and stand at attention. Persons in uniform should render the military salute. Men in uniform should remove their headdress with their right hand and hold it at their left shoulder, the hand being over the heart. Women should place their right hand over their hearts.

When carried in a procession with other flags, the national flag should be on the marching right. If there is a line of other flags, it should be front center of that line. The U.S. flag always should be staffed when carried on a float.

• The national flag should be placed in the center, and higher, when displayed with a group of state, local, or organizational flags flown from staffs.
• When state, local, or organizational flags are flown from the same halyard, the U.S. flag should be at the peak. When flown from separate staffs, the U.S. flag always should be hoisted first and lowered last. It should be higher than adjacent flags.
• If the flag is displayed from a staff projecting from a building, the union should be at the peak, unless flown at half-mast. When flown from a halyard over a sidewalk from a building pole, the flag should be hoisted union first from the building.
• Unless flown from a staff, the flag should be displayed flat or in such a manner that its folds fall free. When suspended over a street, the union should point north or east.
• When used on a speaker’s platform, the flag, if displayed flat, should be displayed above and behind the speaker. when displayed from a staff in a church or public auditorium, the flag of the United States of America should hold the position of superior prominence, in advance of the audience, and in the position of honor at the clergyman’s or speaker’s right as he faces the audience. Any other flag so displayed should be placed on the left of the clergyman or speaker or to the right of the audience.
• When flown from a staff in a church chancel or speaker’s platform, the flag should be placed on the speaker’s right. If not on the platform, it should be on the right of the viewers as they face the platform.
• If the flag is displayed flat on the speaker’s platform, it should be placed behind and above the speaker with the union to his right.
• When displayed against a wall with another flag, the U.S. flag will be on the viewer’s left with its staff crossing over the staff of the other flag.
• When the flag covers a casket, the union should be at the head over the left shoulder. During burial, the flag must not touch the ground nor be lowered into the grave. To fly at half-staff, the flag should be hoisted to the peak, then lowered. The opposite applies when lowering it from half-staff.
• Although the flag may be a distinctive feature at unveiling a statue or monument, it should never be used as the covering or veil.
