Kyle Busch, Larson penalized for swerving after Charlotte race:

Kyle Larson

Kyle Busch and Kyle Larson were held out of the first 30 minutes of practice at Kansas Speedway as punishment for swerving after Sunday's race at Charlotte Motor Speedway. "You swerve, and you're sitting," vice president of competition Scott Miller said Friday.

"That's about all there is to it." It's the first instance in which the infraction has been enforced.

NASCAR executive vice president chief racing development officer Steve O'Donnell warned Sprint Cup drivers before the Sept. 25 race at New Hampshire Motor Speedway of penalties for swerving, which teams have employed to help ensure their cars pass the Laser Inspection Station.Asked whether the teams of Busch and Larson specifically were warned, Miller said the New Hampshire announcement "was pretty specific to what's happening" and noted NASCAR has been analyzing postrace video.
