Do you have experience driving semi-truck? Do you know any one who own an semi-truck and willing to lend you the truck for practice and for tests? First you have to get your "air brake" endorsement done then you can do your class one knowledge test, practice and road test. My advice to you is to go to one of the driving school that offers class one classes it is both the easiest and safest way to obtain a class one license. Do it the proper way for your own safety and everyone driving around you. my 2 cents!
