NASCAR will expand its officiating footprint and the tire-pack infrastructure this weekend at Circuit of The Americas.
Concerns were raised during last year’s race about drivers shortcutting Turn 6 at the Austin, Texas, road course. NASCAR will begin officiating that corner for drivers who exceed track limits — just as rules against cutting the course already were applied last year in the esses section (Turns 3, 4 and 5).
NASCAR is also adding tire packs in Turns 6 and 19, after they were successfully used to monitor shortcuts through the esses last season.
