Nelson Piquet Jr. has been fined $10,000, required to participate in sensitivity training as directed by NASCAR, and placed on indefinite probation for violating the sanctioning body’s Code of Conduct policy.

As you can see in the screenshot above, Piquet Jr. left a homophobic slur on fellow NASCAR driver Parker Kligerman’s Instagram account. This action violated Sections 7-5 (Code of Conduct) and 12-1 (actions detrimental to stock car racing) of the 2013 NASCAR rule book.

“Nelson Piquet Jr. recently communicated an offensive and derogatory term that cannot be tolerated in our sport,” said Steve O’Donnell, NASCAR senior vice president of racing operations. “NASCAR’s Code of Conduct explicitly spells out in the 2013 rule book our position regarding the use of disparaging terms. We expect our entire industry to abide by this Code.”
