The test in IL was Multiple choice, if youve studied and you remember the KEY WORDS, such as Air LEAK DOWN pressures, Braking Distance, Tire pressures, etc youll be fine, The Driving test is more difficult as its now a SKILLS TEST, Ive always driven trucks with a Auto Trans, your license is no different they dont grade you or test you on Transmission types, Since its hard to get seat time and practice the skills test unless you know someone with a truck, I recommend you RENT a NON CDL Straight truck and practice your Backing, alley backing, turning, and stopping skills....its a cheap way to practice the day before you take a test if your planning on driving a Straight truck....Find a large parking lot and practice your PERCEPTION DISTANCES, thats the one I see most people having issues with....there are several sites with the Practice tests, but your CDL book is where the tests originate, learn it, read it front to back...there is no shortcut.
