NASCAR addresses blocking in Daytona drivers meeting

NASCAR Vice Chairman Mike Helton warned drivers in Sunday night's drivers meeting about blocking. Helton explained the genesis of the double yellow line at Daytona International Speedway and Talladega Superspeedway before getting into a discussion about blocking. Drivers are not permitted to go below the yellow lines to advance their position. If so, NASCAR will penalize them. If a driver blocks and forces a competitor below the yellow lines, the driver doing the blocking may be penalized.

"I point to that because blocking is kind of creeping that way here and at Talladega," Helton said told the competitors. "Last night's race, I think, was an example of the unintended consequences that can come from a blocking move. I'm not telling you how to drive a racecar. Lord no, I couldn't do that. But drivers be conscious about the moves you're making on the racetrack, particularly when it comes to what we call blocking. Be thinking about that in tonight's race." NBC Sports
