I run a diesel dually and pull a 42' trailer..
it has a LQ in it and I carry the latest copy
of the regulations just so I can pull it out
and have the person(cop) show me(I have the
pages with a tab on them to say what is and
what isnt legal for me and my rig.. so far I
have never been pulled over.. but I am legal
and I keep my rig clean and always check my
lights daily if I'm using the rig
