After conducting himself unbecoming of a NASCAR driver, oh, wait, this is a USAC fine.. sorry.
Calling his behavior "unacceptable," Tony Stewart was fined $10k and placed on probation for the rest of the year within USAC. He could make it the perfect sweep and get on the S-List of NASCAR too if he tries hard enough.
On top of that, Stewart will also be paying to replace the radios and uniforms of the USAC officials. (What the heck did he do to them?)source: http://www.thatsracin.com
