Drivers on the track get upset. They yell. The scream profanities. Sometimes, they even bump a car a little.
This went over the line, and NASCAR has responded.
During Sunday's Bumper to Bumper 300, a furious Kevin Lacroix -- angry that Alex Labbe made contact with his during the final turn -- slammed into him during the cool down lap and damaged both vehicles. Check this out:
NASCAR took this very seriously. Lacroix has been fined $1,000, loses 10 championship driver's points and has been placed on probation through the end of 2017. Car owner Sylvian Lacroix was also docked 10 owners points.
