I would imagine in SD the interstates like much of Florida's interstates are pretty straight so I'm guessing here that the truck driver either dozed off a bit or who knows what. Unless it was on a curve and well you know.
In Florida there's a law that either you move over one lane or slow down to 20 mph below posted speed limit. So for example if FHP is on the shoulder with light flashing even if it's to help a stranded citizen then you move from the slow lane to the middle lane or stay in slow lane but, slow to 20 mph below posted speed limit. Most FHP fatalities are attributed to the very thing you mentioned.
Even with lots of announcment by radio and local tv before it was enacted it took a while for folks get with the program but, after enough tickets and a couple of years I now see folks moving over most of the time as I travel about 40 miles roundtrip on I-95 each day. You really can't appreciate how fast 55 let alone 70 mph is unless you've been on the shoulder like changing a flat and a semi goes by or even a car...Man it's fast. It ought to be a required field trip exercise for all new licenses but then again safety would be an issue so probably not a good idea.
Hopefully your 2003 incident was w/o injury. Take care and be careful out there.
