Here in ol' Virginny, they'll post "no commercial vehicles or trucks except buses" for the left lane of any four-or-more-lanes highway........ not that I've ever actually SEEN anybody get pulled over for this, and I HAVE seen a lot of violations. (And if you try to keep to the speed limit on the Beltway around DC, you're in danger of getting run over!)
