So okay, I'm trying for a commercial drivers license. The handbook is replete with enough bad English and misspellings to make it difficult enough to simply breeze through, and I hate when something forces me to actually pay attention. Learning about air brakes and the like is cool because it's knowledge, but the things that can screw you up are "At what angle does a trailer begin to jackknife from a tractor", etc.

Off I go to read some more.
