    I believe I've heard this over 100 times now at trucking school. I do focus primarily on the trailer, but sometimes my drive wheels or other parts of the tractor can cross the boundary line too, so I have to pay attention to the tractor sometimes too.


    That's what they told me at CRE. At the truck driving school I attend now, they tell me to just focus on my flat mirrors.

    I've noticed that everyone loves telling people who are straight line backing that they are oversteering, but sometimes I and others will understeer.


    That would cause the trailer to drift to the right even more.

    My instructors tell me that I "overanalyze" everything, but I've tried to back up without thinking, and it's a disaster. Backing up a tractor-trailer is second nature to some people, and they can do it without analyzing it, but I can't learn how to do it without thinking. I've tried to mindlessly less it without analyzing it much, and it's a disaster.

    I've mentioned earlier on this thread that I have one instructor who will turn his steering wheel to the left (when straight line backing) and then he will immediately turn the steering wheel PAST the center point to the right (or vice-versa). It did not occur to me at the time, but I think I know what he is doing now. When the trailer is drifting to the left, he turns the steering wheel to the left to move the rear end of the trailer to the right. Immediately after that, when he turns the steering wheel to the right, I think that what he is doing is just getting the tractor straight with the trailer (as opposed to moving the rear of the trailer to the left).

    Do you people agree with me?

    keeping the truck straight with the trailer is the whole idea.

    but you also have to aim for where your backing to park.

    so it's basically 2 concepts.

    Okay, this is the last time, until next time that I answer this question.

    Some folks here have already put it down and some have put it mostly down but.....

    Backing up straight is a function of the trailer wheels. The wheels on the trailer are supposed to be perfectly alligned but they never are. Therefore the trailer drifts. In zero wind, it will drift either left or right. It will not drift left once and then right. It will always go the same direction. So you put the correction in and then take it out. Do not oversteer. Put it in, take it out. Put it in, take it out. Why is that making me horney.....

    Anyway.... To put the correction in you need to look in your mirrors. If you have you hand on the top of the steering wheel, the trailer will run away from your hand. Move your hand toward the offending rear end of the trailer. If the trailer rear end is moving toward the drivers side move your hand Counter-Clockwise or toward the left. If the rear end of the trailer is moving toward the passengers side, move your hand toward the right or Clockwise. Only move your hand two hours on the clock in either direction. By that I mean move it from 12 to 10 and then back to 12. That should keep it from going back the other way. Little movements not large corrections.

    Local drivers like to use the old suicide knobs and for them they move the wheel in the other directions.

    Now if you are driving for Swift just get out and flag someone down. They will back it up for you for $40.

    Hey expedite_it, don't sweat... :biggrin_25519: it will come to you with practice and time. You just need to take your time and practice... and practice... and practice some more. For me, one thing that helps is to move the truck slowly so I can fix as soon as end of trailer starts going the wrong direction. My instructors used to say, while backing, look in the left mirror (flat one) and if you lose sight of the rear of trailer, move the steering wheel a little to the right... "lose sight, move to the right". Keep backing slowly. Of course, you will have to bring steering wheel back to left (small adjustment) once you see end of trailer in the mirror again. And don't move the steering wheel to much, just a little and watch where the trailer is going. If it goes to left in a angle, move steering wheel to the left, if it goes to the right, move steering wheel to the right. Slowly. Try to do this in first gear, in very slow motion. If you get confused, STOP and figure out where the end of trailer is going and what direction you need to move the steering wheel... That's what I do. Good luck.
