IndyCar changes full course yellow guidelines after Alexander Rossi incident at Sonsio Grand Prix

IndyCar Officiating has again made a post-race rule change following a controversial ruling during a race. IndyCar Officiating will no longer take pit windows and the running orders of cars into consideration when deciding whether to deploy a full-course yellow on cautions. The ruling is a reaction to Saturday's Sonsio Grand Prix at Indianapolis Motor Speedway, where Ed Carpenter Racing's Alexander Rossi's No.

20 Chevrolet stalled at the start-finish line due to a hybrid failure . As Rossi sat in his powerless car on Lap 21, IndyCar race control decided to only deploy a local yellow while keeping the rest of the IMS road course hot. When Rossi exited the car and hopped over the pit lane wall, race control was forced to escalate it to a full-course caution.

"The fact that it took that long to throw a full-course yellow, when a car's on the front straight and people are going by at 170 miles an hour, also seems insane, when they don't let us drive in the wet yesterday," Rossi said on Fox. "So, I don't really know where the priorities lie. So pretty frustrated.

" In the past, IndyCar has hesitated to deploy cautions that would cause a major re-racking of positions or hinder those who were saving fuel as they waited longer to pit than others. The rule change will no longer take those factors into consideration, instead weighing "driver status, vehicle position and condition, the location and readiness of safety personnel, recovery access, and the speeddifferential between affected cars and approaching traffic. " During Rossi's incident on Saturday, two of the race's leaders, Alex Palou and Kyle Kirkwood, had not yet pitted and their pit stands experienced confusion on whether the pits were open during the local caution.
