223rem ----- Semis are enbreastled to use the roadway and know it. Tires are expensive and most of the crap that will flat a tire is on the shoulder. About the only time a trucker is willing to risk that is for blocking the shoulder in a traffic jam so the MFFYs can't use it to muck up the situation... even more worserer.
Personally, I liked to turn my rig into the R lane when turning right (vice-versa), make that big swing around and have my trailer end up dead center and going exactly straight at the finish of the turn. But that isn't always possible or, a lot of the time, practical and-or the safest method.
Operating a truck consists of making an almost constant series of compromises. The average idiot drive one without the compromises, but it isn't very smart. That's why truck "driving" is often referred to as "operating". You drive a car, a truck is operated ala heavy equipment operation... because that's what it actually is. To those who know what the f*** they're doing: operating a piece of large, heavy equipment, at high velocity, in traffic.
Just watch out for trucks. A lot of 'em are doing the best they can with what little brains they got... and some aren't. It's not wise to differentiate between 'em. -----
