"Can't avoid jack-knifing? Don't be a truck driver"
 

"Public Enemy No. 1: tractor-trailer drivers who can't keep their rigs from jackknifing"

(hey, I'm just quoting the guy who wrote that)

Just another idiot who thinks he knows everything. I love how they never take into account when the truck jackknife's to safe the van full of kids who's parent decided to cut the truck off, then slam on the brakes.

Oh, it gets even better...
Now, it would seem they want EVERYBODY to have an accurate CRYSTAL BALL, so that we all know we will not be able to handle a truck without jackknifing one. To be able to look into the future and know that one can never be a truck driver because 5 years down the road, a jackknife is coming.

That's just a little much to expect from entry-level drivers, don't you think?
