USA Today had a moderately interesting article on highway traffic congestion and semi-trucks. The trucker they interviewed objected to laws restricting semis to the right two lanes or lower speed limits for trucks than for passenger vehicles. I can see some merit to his objections — he says, for example, that when trucks are restricted to the right two lanes, they create a wall of trucks that prevent traffic from merging into or off of the highway. And, I think you’re probably always asking for a bit of trouble when you have vehicles traveling at significantly different rates of speed. But, his efforts to point the finger at drivers of passenger vehicles with cell phones seemed a little convenient. Most likely the problem is simply too many vehicles for the amount of road available. Building more roads never seems to solve the problem for very long.
For my part, I get annoyed with the vehicles that just live in the left lanes, regardless of whether they are traveling faster than the traffic in the right lanes or semis that are passing other semis with minimal speed differentials — meaning it takes a long time to complete the pass, and God forbid a hill get in the way during the middle of the pass. The problem with people living in the left lane seems especially prominent among mini-vans in Ohio for some reason.
