Layout, you are asking the wrong questions.
Put it this way, why are they demanding more and more ideas to restrict the trucker? The reason has been because the percentage of the drop in accidents has not been declining enough for the feds. With the number of truck accidents, they want the number to decline double digits every year but in reality that can't be done.
Now we are going to have the CSA2010 and the prevention through analyzing the problem to death methodology used to help that decline increase. Instead of finding the root cause of these problems that they are so focused on, we seem to be going backward with more wrong ideas like some of the CSA2010 and Hours of Duty changes and less input of common sense.
New Jersey is just another state which thinks they know what has to be done to prevent accidents when we know that the solution would be to demand more use public transportation.
