A flag, which is a symbolic piece of colored cloth, is used for signaling, messaging, identification, advertising, or decoration. The exact interpretation of a flag is based upon its usage and location:
* National – symbolizes one’s country.
* Swimming – denotes the limits of a beach swimming area. The poles being crossed indicates the beach is closed.
* Railway – used on a railway, with red meaning stop; yellow meaning carefully proceed; a hoisted green, blue, or white meaning proceed; a blue attached to the side of a train meaning not to move because work is in progress; a blue on the track meaning not to remove or displace anything on the track; and any color being waved vigorously meaning stop.
* Sports – colored flags used during sporting events. For example, the checkered flag used in auto racing to signal the conclusion of a race or the flags thrown by football referees to signal an error in play.
* Sea – flags often used to signal other ships when a ship is in distress and doesn’t have other communication means. Click here to read more.. »
