Raising and Lowering the Flag

The flag should be raised briskly and lowered slowly and ceremoniously. Ordinarily it should be displayed only between sunrise and sunset. It should be illuminated if displayed at night.The flag of the United States of America is saluted as it is hoisted and lowered. The salute is held until the flag is unsnapped from the halyard or through the last note of music, whichever is the longest.
During the ceremony of hoisting or lowering the flag or when the flag is passing in a parade or in review, all persons present in uniform should render the military salute. Members of the Armed Forces and veterans who are present but not in uniform may render the military salute. All other persons present should face the flag and stand at attention with their right hand over the heart, or if applicable, remove their headdress with their right hand and hold it at the left shoulder, the hand being over the heart. Citizens of other countries present should stand at attention. All such conduct toward the flag in a moving column should be rendered at the moment the flag passes.

Displaying the Flag Outdoors

When the flag is displayed from a staff projecting from a window, balcony, or a building, the union should be at the peak of the staff unless the flag is at half staff.

If the flag is suspended over a sidewalk, the flag's union should be farthest from the building. When the flag is suspended over a sidewalk from a rope extending from a house to a pole at the edge of the sidewalk, the flag should be hoisted out, union first, from the building.

When the flag is displayed over the middle of the street, it should be suspended vertically with the union to the north in an east and west street or to the east in a north and south street.

When it is displayed from the same flagpole with another flag - of a state, community, society or Scout unit - the flag of the United States must always be at the top except that the church pennant may be flown above the flag during church services for Navy personnel when conducted by a Naval chaplain on a ship at sea.

When flown with flags of states, communities, or societies on separate flag poles which are of the same height and in a straight line, the flag of the United States is always placed in the position of honor - to its own right.
..The other flags may be smaller but none may be larger.
..No other flag ever should be placed above it.
..The flag of the United States is always the first flag raised and the last to be lowered.

When flown with the national banner of other countries, each flag must be displayed from a separate pole of the same height. Each flag should be the same size. They should be raised and lowered simultaneously. The flag of one nation may not be displayed above that of another nation. The order of precedence for flags generally is National flags (US first, then others in alphabetical order in English), State (host state first, then others in the order of admission) and territories (Washington DC, Puerto Rico, etc.), Military (in order of establishment: Army, Marine Corps, Navy, Air Force, Coast Guard), then other.

The flag, when flown at half-staff, should be first hoisted to the peak for an instant and then lowered to the half-staff position. The flag should be again raised to the peak before it is lowered for the day. By "half-staff" is meant lowering the flag to one-half the distance between the top and bottom of the staff.

When the flag is used to cover a casket, it should be so placed that the union is at the head and over the left shoulder. The flag should not be lowered into the grave or allowed to touch the ground.

When the flag is displayed in a manner other than by being flown from a staff, it should be displayed flat, whether indoors or out.

That the flag, when carried in a procession with another flag, or flags, should be either on the marching right; that is, the flag's own right, or, if there is a line of other flags, in front of the center of that line.

The flag of the United States of America should be at the center and at the highest point of the group when a number of flags of States or localities or pennants of societies are grouped and displayed from staffs.

When the flag is displayed on a car, the staff shall be fixed firmly to the chassis or clamped to the right fender.

The flag should NOT be displayed on a float in a parade unless it is flown from a staff or displayed flat against a "wall" on the float, similar to the way it is displayed on a wall behind a speaker's platform. The flag should never be draped over any part of the vehicle, including draping it across the front of the vehicle for parade purposes. When you fly the flag from a vehicle in a parade, remember the rule about prominence. This means the flag should be to the right of the driver, preferably mounted securely to the right, front fender. It is a common mistake to fly the flag from the REAR of a vehicle but remember the rule.

Showing Respect to the Flag

The flag should never be dipped to any person or thing. It is flown upside down only as a distress signal. (This tradition may come from the 1908 Summer Olympics in London, where countries were asked to dip their flag to King Edward VII: the American flag bearer did not. Team captain Martin Sheridan is famously quoted as saying "this flag dips to no earthly king", though the true provenance of this quotation is unclear.)

If flown at night, the flag must be illuminated.

The flag should not be used as a drapery, or for covering a speakers desk, draping a platform, or for any decoration in general. Bunting of blue, white and red stripes is available for these purposes. The blue stripe of the bunting should be on the top.

The flag should never be used for any advertising purpose. It should not be embroidered, printed or otherwise impressed on such articles as cushions, handkerchiefs, napkins, boxes, or anything intended to be discarded after temporary use. Advertising signs should not be attached to the staff or halyard.

The flag should not be used as part of a costume or athletic uniform, except that a flag patch may be used on the uniform of military personnel, fireman, policeman and members of patriotic organizations.

The flag should never have placed on it, or attached to it, any mark, insignia, letter, word, number, figure, or drawing of any kind.

The flag should never be used as a receptacle for receiving, holding, carrying, or delivering anything.

The flag should never be carried flat or horizontally, but always aloft and free.

The flag should never be fastened, displayed, used, or stored in such a manner as to permit it to be easily torn, soiled, or damaged in any way.

The flag should never be used as a covering for a ceiling.

The flag represents a living country and is itself considered a LIVING THING. Therefore, the lapel flag pin being a replica, should be worn on the left lapel near the heart.

If the edges become tattered through wear, the flag should be repaired or replaced.

When a flag is so tattered that can no longer serve as a symbol of the United States, it should be destroyed in a dignified manner, preferably by burning.

It is a common myth that if a flag touches the ground or becomes soiled, it must be burned as well. While a flag that is currently touching the ground and a soiled flag are unfit for display, neither situation is permanent and thus the flag does not need to be burned if the unfit situation is remedied.

Although the Flag Code is U.S. Federal law, there is no penalty for failure to comply with the Flag Code and it is not widely enforced—indeed, punitive enforcement would conflict with the First Amendment right to freedom of speech.
