START – (in absence of lights) #
For rolling starts, karts start at the moment the flag is raised.
For standing starts, karts start at the moment the flag is dropped.
A service vehicle or slow moving kart is on the circuit. #
The flag will be waved to indicate the sector of the track that the slow moving vehicle is in, and held stationary whilst the vehicle is in the next sector.
Change of surface ahead #
This could mean there is something in the road ahead, water / oil / stones / mud on the circuit.
Caution through this sector.
Immediately cease driving at racing speed #
Proceed slowly, without overtaking, and with maximum caution to pits or start line obeying marshal’s instructions, and being prepared to stop should the track be blocked.

Immediately slow down #
Immediately slow down and form up behind the leader, no overtaking. Continue at a reduced pace, with no overtaking until a green flag is shown at the start finish line. The race leading kart must slow down to a steady pace (as on a rolling start lap).
All clear, at the end of a danger area controlled by yellow flags #
Also used to signal the start of a formation lap and shown at all posts during first lap of each practice session and during the formation lap.
End of race or practice #
False Start #
Slow down and reform the grid. Continue on another rolling lap, stay in formation at the speed set by the pole sitter at the front.
The following flags will be shown with a board displaying the race number of the individual competitor(s) that the flag is relevant to. #

Warning to the driver that their behaviour is suspect and that they may be black-flagged on further reports.
Notification of apparent mechanical failure or a fire #
Might not be obvious to the driver. The kart concerned must call at the pits for repairs / retirement on the next lap.
The driver must stop at the pits within one lap of receiving the signal and report to the clerk of the course #
A penalty of exclusion may be enforced.
