With the caution flags removed at the end of the stages during both of the road course races at Sonoma Raceway this past weekend, there were less than a total of six caution flags between the Xfinity and Cup Series races.

While there were a couple of penalties issued during the the Cup Series race on Sunday, the Xfinity Series had a clean race.  And there were no penalties in either series for pre-race inspection violations.

However, there was just one penalty after post-race inspection in the Xfinity Series when the number 21 car driven by Austin Hill was found to have  a single lug nut was improperly secured.

As a result, crew chief Andy Street has been fined $5,000.
