Good luck trying to get such an endorsement, because such a thing does not exist on US licenses.
The answer is no. Someone who holds a CDL must complete and pass the written air brakes test and perform their road test in a vehicle so equipped, otherwise they get a "no air brakes" restriction which prohibits them from operating a commercial vehicle equipped with air brakes, but doesn't prevent them from operating a vehicle exempt from CDL requirements which is equipped with air brakes.
On a US licence, there is no air brake endorsement - there is only a restriction for CDL drivers from operating a commercial vehicle equipped with air brakes if they don't complete the written test AND road test in a vehicle equipped with air brakes.
There is no such thing as an air brake endorsement on a US license - only a restriction for CDL holders who do not pass the written air brakes test and perform their pretrip and road tests in a CMV which is equipped with air brakes.
There isn't an air brake endorsement. If you haven't completed and passed the written air brakes test at the DMV and conducted your road test in an air brake equipped CMV, then you have a restriction prohibiting you from operating a CMV equipped with air brakes. You take the written test and do the road test in an air brake equipped vehicle.
In the US, no - there is no such thing as an air brake endorsement - only a restriction for CDL holders who don't pass the written air brakes test and complete the pretrip and road tests in a vehicle equipped with air brakes, which prohibits them from operating vehicles requiring a CDL which are equipped with air brakes.
There is no such thing as an air brake endorsement on any US license, CDL or otherwise. Only a restriction for CDL holders if they don't complete the written air brakes test and perform their pretrip and road tests in a CMV equipped with air brakes, which prohibits them from operating a vehicle requiring a CDL which is equipped with air brakes.
That depends on which country you live in.
As much as their company is willing to pay them. You could have a Class B CDL and drive a trash truck, dump truck, roll off truck, oilfield truck, or have a job where driving isn't even the primary line of work. By the way, there is no such thing as an air brake endorsement on a US license - only a restriction for CDL drivers if they don't pass the written air brakes test and perform their pretrip and road tests in a vehicle equipped with air brakes.
No. Such an endorsement does not exist for US licenses.
If it does not require a CDL to be driven, there are no additional requirements. Such an endorsement does not exist on US licenses.
You can't get one. Primarily, because there is no such thing as an air brake endorsement on a US drivers licence. For a non-commercial vehicle (as defined by the FMCSR), absolutely no knowledge of, testing of, or training on air brake systems is required. It is only applicable to CDL holders. If they do not take both the written air brakes test AND conduct their road test in an air brake equipped vehicle, they receive a restriction on their CDL which prohibits them from operating air brake equipped commercial vehicles.
Depends on your country. If you have an air brake endorsement, then you're not in the US, as there is no such thing here. Other countries require it. Your licensing requirements for operating that vehicle will also depend on the Gross Vehicle Weight Rating.
If you're in the US, there is no such thing as an air brake endorsement. CDL drivers receive a restriction which prohibits them from operating a commercial motor vehicle equipped with air brakes if they do not pass both the written air brakes test and do their road test in a vehicle equipped with air brakes.
