Summarize:

Buildings and outdoor flag staffs should be flown from sunrise to sunset. If a national flag is flown at night, it should be brightly illuminated with proper lighting, such as that of a spotlight.  National flags should not be flown in bad weather, such as heavy rain or thunderstorms, unless the flag is an all-weather flag. Some nations require that during a brief period of precipitation, the flag be lowered until the weather clears. in a position superior to all other flags. The national flag should fly higher than other flags present. This includes state and provincial flags. The exception to this is when flags of other countries are also displayed, such as at the United Nations or during the Olympic Games. If multiple flags are flown on the same staff, the national flag is to be flown above the others, at the top of the staff. When flags of multiple countries are flown in the same place, they must all be displayed as equals. They should each be flown on individual flagpoles, each of the same size.  All of the flags must be the same size and no flag can be bigger or smaller than another flag. National flags of multiple countries should be arranged in alphabetical order. When displaying flags in a line, the position of the national flag in relation to other (non-national) flags changes based on the number of flags present. These range from two flags, to five or more.  When two flags are displayed in a line, the national flag should appear on the left side when viewed by an observer. When three flags are displayed in a line the national flag should be in the middle (or the second flag). When four flags are displayed in a line, the national flag should be the first flag on the left when viewed by an observer. When five or more flags are displayed in a line, two national flags should appear at both ends of the line. In other words, in a line of five flags, the national flag should appear as the first flag and the fifth flag. When displayed horizontally or vertically, the flag should be hung correctly, in accordance to the nation’s wishes. In the case of the US flag, this means the union (the blue field of stars) should be displayed uppermost and to the flag’s own right. This will be to the observer’s left. Note that some nations restrict their flag from being hung in this fashion, or have specific instructions for doing so. When carried in a parade, the national flag should be carried on the marching right. If there is a center of flags in a line, the flag should be carried in the center of that line. The flag must hang freely.  If the flag is displayed on a float, it must be hanging from a staff. The flag is not to be draped over any portion of a vehicle. Flags featured on a float must otherwise follow standard flag procedure when displayed with other flags. Events with public speakers, such as those that occur at a podium, should hang freely from a pole, superior to other flags present. The flag should be located to the speaker's right side, as a sign of honor and respect. For those observing the speaker, this will be on the speaker's left.
