"Through time you have to recognize when you get a reminder or tap on the shoulder, something that may need to be addressed," Pemberton said. "This is one of those times where we look outside our sport and we look at other things, and we feel like it was time to address this."
"Really, we're formalizing rules that have been there," Robin Pemberton, NASCAR's vice president of competition and racing development, said at Michigan International Speedway. "It's reminders that take place during drivers meetings with drivers about on-track accidents. We're just formalizing this and it's something that we worked on this week."
