This has nothing to do with the car sponsors, or the signage on the cars, trucks, awnings or tow cars.
To use the tool companies just as an example. If Doug Herbert has a model at his pit handing out Snap-on info, that's one thing. If he sends this model over to stand in front of the Kalitta pit to hand out Snap-on info, would that be OK? What about any of the other MAC TOOLS cars?
I'm guessing that most of you said no.
So the issue becomes where do you draw the line? And the answer is at the end of the pit stall. So if your model is roaming the pits, she is breaking the rules. It's not a matter of sponsoring the cars, it's a matter of what is and isn't allowed at the track.
