Racing Flags


In motorsports, flags are waved from observation post on the side of the track to notify drivers of danger or to give instructions from Race Control.

Observation post locations and flag locations are determined at each circuit and have been approved by the FIA or ASN. Therefore, it is not possible to change the location where the flag is waving without permission.

There are many different types of racing flags waved on the circuit. Operation rules are different for automobiles and motorcycles. Therefore, the operation rules of the flag are explained clearly.
