Daniel's pretrip, while excellent, wouldn't have quite passed with the DOT in Kentucky where I tested, but it should easily do for illinois which allows 3rd party testers. I can't remember now what it was missing for Kentucky, but only DOT does testing and they want everything to worded and described a very specific way and give a handout to the CDL school there listing exactly what they want with no deviations.. about 20 pages of info lol.
