NASCAR alters bus stop chicane at Daytona road course

NASCAR has tweaked the Daytona International Speedway Road Course’s bus stop chicane before this weekend’s national series tripleheader, following driver feedback from the season-opening Busch Clash.

The sanctioning body added rumble strips to the Turn 9 and Turn 10 chicane on the backstretch to prevent cars from getting into the grass and spraying dirt onto the racing surface and other cars.

The rumble strips will be the same as the front chicane. The one to the driver’s right on entry is approximately 36 feet long, and the other is approximately 30 feet long.  NASCAR.com
