stupid is stupid does ??

I am not sure that I understand your situation. You have passed the written tests to get a CDL learners permit? These permits are something new since I retired. Let me make the following point. Most of the time in truck driver training will be spent on the practice range and on the road, not in the classroom. Most of the time, you will be driving, riding with an instructor while another student drives, or riding while the instructor drives. It takes at least four weeks because apprentice style training involves demonstration by the instructor followed with practice by the student, over and over again, until certain things such as gear shifting become second nature. In the beginning, students will drift out of their lane while coping with the transmission, speedometer and tachometer. Only with weeks of practice will students be competent to go out on their own; and you can not train your body by reading about it.
