A competitor’s second violation is cause for receiving the black flag and removal from the track.
4.7.8 If there is a yellow flag before completion of 1 lap, the original start position is assumed for all karts/kars. Drivers are urged to remember the kart/kar number lining up in front of them and reform the starting line as to avoid the necessity for a red flag.
