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.
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.
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.
Yes. A Class 7 single axle straight truck exceeds the 26000 lb. GVWR. A semi truck is a Class 8 truck.
That combination, unless it's hauling hazardous materials, doesn't require a CDL at all. Now, if that was a 12,000 GVW trailer, then a Class A would be required. There is no such thing as an air brake endorsement - only a restriction, and only applicable to vehicles requiring a CDL.
26000 lbs of cargo? A tandem straight truck, such as a flatbed or a dump, could haul that amount of weight legally.
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.
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.
In some instances, yes.
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.
No.
That would depend on the weight rating of the trailer and bridge law. For a straight truck, five to seven tons.
