They dont pull over every little violation,but if they have a reason to pull you over they tend to add all the other citations.There are tons of cops around for the event due to the large amount of people.Last year each day had 100k plus people.Every one know what happens with that many people in a small area drinking.Alot of showing off and attempts to drag race and so on.So when they pull you over they start writing a nice long list.Only time they would bother you is if they think it is a safety hazard.One that really bothers them is the tires past the fenders,and the bumper heights.PA law on bumpers is to protect smaller vehicles so if there is an accident you bumper does not go over hood and into the windshield.
