1) The feds dont force you to do so.
2) You dont have a “right” to operate a motor vehicle on public roads.
I respectfully disagree...I built the highway, I pay for the maintenance of the highway, I do not need permission of the state to go from state to state in this country, I purchase and license my vehicle therefore I have the right to use the highway......I have, however CHOSEN to allow states to ascertain that YOU are worthy of driving on my highway......by so doing, I will also go along with being tested to make sure that I am also capable of driving on your highways......I guess it's better this way....the pioneers did not seek the permission of anyone to drive their conostoga wagons to California
You do indeed have a RIGHT to operate a motor vehicle on public roads.
