The presence or absence of air brakes has no impact on whether or not that vehicle requires a CDL.
Air brakes have absolutely nothing to do with determining whether or not a vehicle requires a CDL.
No. Air brakes are not a parameter in determining whether or not a vehicle needs a CDL.
If it's a registered farm vehicle, then typically, no, although the licence requirements for vehicles exempt from CDL regulations vary between states - some states may require an upgraded non-CDL licence, and may require the air brakes test to be taken. If it's a commercial use vehicle, and not registered as a farm vehicle, then they would need a Class A CDL without an air brake restriction (there is no actual air brake endorsement).
If the vehicle is for commercial/business use, or otherwise does not fall into an exempted category with the FMCSR which makes it not require a CDL (and is operated within the conditions which must be met for that exemption to be applicable), then that vehicle requires a CDL. If it is equipped with air brakes, and requires a CDL, then the driver must have completed and passed the written air brakes test, and must have performed their pretrip and road tests in a CDL vehicle equipped with air brakes. Otherwise, they get a restriction which bars them from operating a vehicle which requires a CDL and is equipped with air brakes. If the vehicle does not require a CDL, then no endorsement for air brakes is needed - air brake endorsements do not exist on US licenses; only the aforementioned restriction for CDL holders.
Only on vehicles which require a CDL to be driven. Recreational vehicles, rental trucks under 26,000 lbs. GWR, etc. do not require a CDL, unless they're either designed to carry more than 15 passengers (including the driver), or carrying hazardous materials in a quantity sufficient to require placarding. ______________ You may want to double check that.......... I think in all states you do need a CDL with an Air Brake Endorsement to drive a truck with air brakes. It would probably mean that you would have to have a Class B also. I don't think there is any trucks made with air brakes that have a light enough gross rating that they wouldn't require a Class B to drive. _____________
The presence or absence of air brakes in a vehicle has no effect of whether or not it requires a CDL.
Air brakes have absolutely NO effect on whether a vehicle requires a CDL or not.
Air brakes aren't even a factor in determining whether or not a vehicle requires a CDL.
This will depend on: What use the bus is put to. Are you carrying passengers? Then yes CDL required What licence it has on it. Non commercial non passenger may not require CDL Air brakes. CDL required.
There is no air brake endorsement - if a CDL driver does not complete the air brakes portion of the written test, and test in a vehicle equipped with air brakes, then they get an "L" restriction on their CDL, prohibiting them from driving commercial vehicles with air brakes. For some bizarre reason, this only applies to CDL drivers - an F750 equipped with air brakes and grossing at 26,000 lbs or less does not require a CDL or air brake permissions. If it's loaded to the point where it weights 26,0001 lbs or more, now it requires a CDL without an air brake restriction. If it weighs under 26,000 lbs. but is designed to transport more than 15 persons (including the driver) or is transporting hazardous materials, then again, it'll require a CDL with the appropriate endorsements and no air brake restriction. But Joe Average can drive around in a U-Haul or RV weighing significantly more than anything they've ever driven in their entire life, and equipped with air brakes, and it requires not one additional bit of licencing or training for them to be able to do this.
There's no such thing as an air brake endorsement on any US license - only a restriction for CDL holders which bars them from operating a vehicle requiring a CDL which is equipped with air brakes if they don't pass the written air brakes test and perform their pretrip and road tests in a CMV which is equipped with air brakes.
