Nope no protection from coach. Only HMS has that power.

Well maybe now some of the hate on here for Denny will slow down. Dale Sr stood up for the drivers also, and had a lot of fans that booed him. When have You seen a HMS driver do it?? They don't have to because they get to do what the hell they want and ASSCAR turns a blind eye.
You will know today most likely, as I am sure if it is out on the net, he will be the recipient of a ticket from Asscar. That is the way they do business, and as I have said all along, THEY ARE CROOKED. When is the last time You saw Larson who passes many cars leaving pit road get ticketed?? I have seen it where a car he passes gets the ticket, and wonder how can he pass the speeding car if he isn't speeding.
Asscar picks and chooses who they like and dislike.
