Pit road closed (pit entry lanebrane locked) cars on pit road can finish fueling and Tires.
Lane brane forces all traffic to a lane outside of pit exit. so safety car may enter track without being hit
Safety car enters track from pit exit
position of all cars frozen
no cars should pass safety car.
All cars must maintain position (drivers will have to allow room to change lanes being courteous and maintain position) no laps are counted until are cars are in proper position
when all cars are in proper position Pit road opens
X= number of laps Safety car returns to pits
x= number of laps green flag at start finish line no speeding before green flag
this is just how I would do it if I could automate this... im positive its not perfect, but this is the most basic Yellow flag I have experienced over the years.
i know there are people who would love Prototypical rules for all of the major Race Divisions, but this seems to work with oval and road course type racing
