NASCAR is going to review its procedures for the Chicago street course race after the delay in throwing the caution for Cody Ware’s head-on impact at the end of Sunday’s race.Ware blew a brake rotor going down into Turn 6 and had a full-speed impact with the tire barriers.

During the Chicago Street Race, Cody Ware slammed into a tire barrier at 93mph and as smoke poured out of his wrecked car, he radioed two chilling words: “Need help.” But for nearly 35 seconds, nothing happened.
