Alright this can get complicated. The difficutly of the test depends on a couple of things. 1. Are you getting a class A,B, or C? 2. What state do you live in? 3. Are you going to be getting any endorsements like Hazardes or Passenger vehicle. Over all if you go for you Class A "this is what I have" you looking at roughly 125 to 150 questions at the local DMV. After you get your permit you will have to pass the Vehicle checklist and driving test. For the check list you must successfully point out 70 to 75 out of roughly 120 points on the truck, tell them what it is and why you are checking it. You cannot read off of a paper!!!! For the driving test as long as you don't speed or run anyone over you should be fine. what gets most people is the backing up straight part and backing up in a turn. They set out cones and if you stray farther than three feet or hit the cone you fail auto matically. Things to think about. Depending on what state you live in expect Random drug and alcohol screening. Test positive you loose you licience. Also in most states if you get pulled over driving your personal vehicle for anything its double the fine and double points because you are a professional driver. Also your BA level for alcohol is cut in half so if it is .08 where you live than yours will be a .04 now.

Not to be as technical. It is very hard (without proper training), and will cost around $5-7,000

its probably hard to get any license, dont know how much it cost
