Colour Royal Blue

A plain royal blue coloured flag.

The plain royal blue coloured flag is also part of our range of motor racing flags and is included in our set of 11 motor racing flags. In motor racing, the plain royal blue coloured flag is used to indicate to cars being lapped that they should give way to faster cars; however, this is not mandatory, so the plain royal blue coloured flag is sometimes referred to as the 'courtesy flag'.
