Following feedback from drivers and a review of data, NASCAR and Speedway Motorsports replaced the blue rumble strips in Turn 16 prior to Sunday’s NASCAR Cup Series Playoffs race at the Charlotte Motor Speedway Roval.
On Saturday night following the NASCAR Xfinity Series race, the blue, 4-inch tall rumble strips were replaced with red-and-white stripes that measure 2.25 inches tall. The new strips were painted blue, and the rules will not change for today’s Round of 12 elimination race.

Vehicles must run on the full course at all times.
-
Going straight at the chicane(s) may result in a stop-and-go penalty.
-
In the closing laps of the race, if there is not enough time to assess a pass-through penalty, a post-race time penalty of 30 seconds will be assessed to the vehicle’s total time.
