When I went through Sage truck driving school back in '04, the instructors told us in class that semis are supposed to stay out of the far left lane when there are more than two lanes running in the same direction, even if there were no signs posted that prohibited trucks from using that lane. The instructors said semis should stay in the right two lanes...I see them using the far left lane all the time now, like they think that lane is there specifically for them or something...
