Checkered pattern on paramedic fly-car
A 'checkerboard' (or 'chequerboard') is a board on which
American checkers is played. It is an 8×8 board and the 64 squares are of alternating dark and light color, often red and black.
The term checkerboard is also used to denote any rectangular square-tiled board. In this sense it refers not to a physical board as such but to the
mathematical abstraction of such a board. The adjective ''checkered'' may refer to a pattern resembling a checkerboard, as in the
checkered flag used to welcome the winning cars in a
Formula One race, for instance, or the livery on some emergency service vehicles.
An 8×8 board is also used for some other
board games, although not necessarily a board with an alternating pattern:
