Kyle Busch (18) rammed Ron Hornaday Jr. (33) during a caution period in the NASCAR Camping World Truck Series race Nov. 4, 2011 at Texas Motor Speedway. NASCAR officials took quick action, parking the driver for the Nationwide and Sprint Cup races that weekend — a costly move for a driver contending in the Chase for the Sprint Cup.

Kurt Busch was already on probation when he told a reporter that it was that fact that "refrains me from not beating" him up, though in relatively more colorful language. That confrontation, which came on pit road following the Nationwide Series race at Dover International Speedway in June 2012, was the latest in a series of Busch run-ins with members of the media that had resulted in monetary fines. This time, NASCAR went a step further and suspended the Phoenix Racing driver for one race.

Infraction: His car body failed to match the templates at a postrace inspection at the NASCAR Research and Development Center following the opening 2010 NASCAR Chase for the Sprint Cup race at New Hampshire Motor Speedway, which he won. Bowyer was penalized 150 points, crew chief Shane Wilson and car chief Chad Haney were suspended six races and fined $150,000 and team owner Richard Childress was penalized 150 points. The team appealed the penalties all the way to the chief appellate officer, who upheld the point deduction but reduced the fine, to $100,000, and suspensions, to four races each for Wilson and Haney.

Defending series champ Keselowski and Penske Racing teammate Logano were each assessed 25-point penalties following infractions in the race at Texas Motor Speedway. The penalties went further, though, with each losing his crew chief (Paul Wolfe for Keselowski and Todd Gordon for Logano), car chief (Jerry Kelley for Keselowski, Raymond Fox for Logano) and team engineer (Brian Wilson for Keselowski and Samuel Stanley for Logano) to suspension for six points races in a span that also covered the all-star race. Travis Geisler, who serves as team manager for both the No. 2 and No. 22 cars, was also suspended six points races.

Infraction: Team owner Childress had a confrontation with driver Kyle Busch following a Camping World Truck Series race at Kansas Speedway in June 2011, allegedly punching Busch several times during the clash. NASCAR deemed the actions detrimental to stock car racing, fined Childress and placed him on probation for the rest of the year.

Jeff Gordon (24) hit the wall after contact with Clint Bowyer (15), then hit Bowyer when he came back around the track to cause a major pileup at Phoenix International Raceway on Nov. 11, 2012. A day later, Gordon was fined 25 championship points, $100,000 and placed on probation until the end of the year.

NASCAR levied harsh penalties to the Penske Racing teams of defending series champion Brad Keselowski and Joey Logano following infractions discovered at Texas Motor Speedway, then heavier fines to Matt Kenseth and his Joe Gibbs Racing team when the engine failed to meet specifications on April 24.

They're not the first to be caught by NASCAR, though. Check out the biggest hits NASCAR has levied in history against teams caught crossing the line.
