Tandem placement and turning radius

Not necessarily. Whether or not you are good to go once the tires get past the obstacle depends on the angle of the trailer when the trailer goes through the gate at the guard shack. It would not be impossible for the trailer to hit the guard shack at a point behind the tires if the trailer entered at the wrong angle.

 

If it is all about when the tandems get past the obstacle, then why is trailer swing irrelevant? What you wrote seems like a contradiction to me.

 

Why does it have to be considered rocket science to discuss how something works? You make it sound as though anything that is not so obvious that it just goes without saying must then be rocket science. Isn't there anything in between?

If it is true that once you get the tandems past the obstacle, you are good to go, then why is trailer swing irrelevant to why someone is able to get the trailer past the guard shack? What makes the tandems the deciding factor if trailer swing is irrelevant to this? The trailer is 53 feet long regardless of where the tandems are.

Why have truck driving schools at all if everything about how to maneuver a semi-truck is just common sense?

 

In post #61, FLD wrote that once the tandems get past the obstacle, you are good to go, and trailer swing is irrelevant to why you are good to go once the tandems get past the obstacle. Do you agree with FLD's post #61?

If once the tandems get past the obstacle, you are good to go, then why is trailer swing irrelevant?
