A NASCAR executive said that series officials clarified a rule on starts and restarts after drivers came to them with concerns before Sunday's race at Kansas Speedway.
The result was Richard Buck, managing director of the Cup Series, telling competitors in the drivers meeting: "A reminder to stay in your lane until you cross the start-finish line. The front row establishes the lanes and the inside lane must be established above the inside painted line.''
Martin Truex Jr. and crew chief Cole Pearn admitted they missed the directions in the meeting. Truex was penalized on a restart when he went below the white line. Kevin Harvick followed Truex below the white line but was not penalized.
Steve O'Donnell, executive vice president and chief racing development officer for NASCAR, explained the rule Monday on SiriusXM NASCAR Radio and why Truex was penalized and Harvick wasn't.
"We had some discussions early on with some of the competitors on Sunday morning about the fact that not necessarily just the inside lane, but if the inside car dropped below the white line it would force, potentially, the outside row or one of the drivers in the outside row to change lanes and the fear of being penalized,'' O'Donnell said.
"We were asked to see if we could clarify that. That was why the language was put in place in the drivers meeting. Clearly communicated by Richard (Buck) to stay above the while line. It was really the first row of drivers that set that line so anyone who is following them was going to be put in a tough position because they had to stay in line, so that was why the penalty was called on (Truex) and not the drivers that dropped below behind (Truex).''
