Well. People are certainally allowed to do whatever they want during the Red Flag, But they cannot interrupt the race, or sabotage the race during The Red Flag, It leads to a longer red flag.
HERE IS A RULE FOR NASCAR RACE EVENT POSTS IN THIS STREAM. FOR EACH CAUTION, THE POST WILL BE SPLIT, SO PEOPLE ARE ALLOWED TO CONTINUE IN THE COMMENTS, AFTER THEY ARE DONE, THEY WILL RESTART THE RACE. IF THE CAUTION CAUSES A OVERTIME, YOU MAY NOT CONTINUE IN THE COMMENTS, INSTEAD, THE RACE WILL GO TO A GREEN-WHITE-CHECKERED FINISH TO DETERMINE THE RACE WINNER, ONCE THE LEADER TAKES THE WHILE FLAG, THE NEXT FLAG ENDS THE RACE. *RACE INTERUPTIONS WON'T BE TOLERATED*
