Assuming this is a commercial use vehicle, and not a registered farm vehicle or recreational vehicle (which are exempt from CDL requirements), the answer is no, unless:
If the vehicle ends up requiring a CDL, you must take the written air brakes test at the DMV along with all the other written tests for your CDL, and you must perform your road test in a vehicle equipped with air brakes. Otherwise, you receive a restriction on your CDL which prohibits you from operating a commercial vehicle equipped with air brakes.
No.
In some instances, yes.
Persons with an Ontario Class DZ licence are licenced to drive vehicles such as straight truck, dump truck, cement truck, garbage truck and rescue & fire trucks - with airbrakes. A Class D licence is required to operate a vehicle over 11,000kg with a towed trailer not over 4600kg. Should your towed trailer exceed 4600kg, you will need to upgrade to a Class A licence.
If the Gross Vehicle Weight Rating - not the actual laden weight at the time - is under 26,000 lbs., then no. You will, however, need a current and valid DOT medical card.
You need to call your state's DMV on this. I know I have seen the F750 registered as a 26k truck before, but the laws on this will vary by state.
Only if it's a: transporting hazardous materials or b: a bus designed to transport more than 15 persons (including the driver).
Need to know which jurisdiction you live in to answer this question. In the US, the presence of air brakes on a vehicle has no impact on the license class, and that would be determined by the Gross Vehicle Weight Rating of the vehicle. Most likely, you would need a Class B CDL for the vehicle you're describing.
Not unless it's a bus designed to transport more than 15 passengers (including the driver).
No. Such an endorsement does not exist for US licenses.
Only if it's transporting 16 or more persons (including the driver) or sufficient quantities of hazardous material to require placarding with HAZMAT warning signs.
To answer you we need to know what country's traffic regulations you are asking about.
No just read the section in the drivers manual. Airbrakes the go to your BMV and take the test I think its 25 to 30 questions over airbrakes
