You really need to attend a driving school, or else go through a company which has their own driver training programme. The written parts of the test are easy enough, and can be accomplished simply by reading the manual - air brakes, combination vehicles, etc. However, the part which will get you is the road test - the state does not provide a test vehicle, and, in many states, road testing is done through third party testing facilities (using driving schools or company driver programmes) and the state DOT will not have the facilities to conduct a CDL road test.
However, for starters, you can go to your nearest DMV office, and obtain the CDL handbook - CDLs are federally regulated, and all states have the exact same material in their CDL handbooks.
Everything you need is in the CDL handbook. Read it. Study it. Learn it.
You need a Commercial Driver's License (CDL). You can get it at the Driver's Licence place. But I suggest you get the books on a CDL and study first !
You'll need to study for the General Knowledge and Combination Vehicles tests. Also, if applicable, Air Brakes.
Get the CDL handbook and study it.
That depends on what class of CDL you're going for. For a Class A CDL, you'll need to study General Knowledge, Combination Vehicles, and air brakes if applicable. For a Class B CDL, you'll need to study General Knowledge and air brakes if applicable. For a Class C CDL, you'll need to study General Knowledge, air brakes if applicable, and either Hazardous Materials or Passenger Vehicles since the only instance in which you'd obtain a Class C CDL is if you were operating a vehicle under 26,001 lbs. GVWR which was either hauling hazardous materials or else was a bus designed to transport more than 15 persons (including the driver). Any endorsements you'd need will also have to be studied (e.g., hazmat, tanker, doubles and triples, passenger vehicles).
Yes. Go to your DMV, and ask for a CDL handbook.
Yes, you will need insurance to drive with a CDL license.
They're all in the CDL handbook. Study it, learn it. If you're not competent enough to do that, you have no business holding a CDL.
The answers for every state's CDL tests are found in the CDL handbook. If you're not willing to study it and learn these things, well, it's probably for the better that you don't get a CDL.
All of them.
Yes you do need a CDL License to drive a bucket truck.
All the answers to the questions on the written test are provided at no charge in the CDL handbook. All you have to do is study it.
