Firefighting and emergency response vehicles are exempt from CDL requirements under federal law. The state may, however, require that a non-CDL Class A or B licence be held by the driver of the vehicle, and individual department policies may require a CDL, rather than a non-CDL licence.
Air brakes have absolutely NO effect on whether a vehicle requires a CDL or not.
Yes you do need a CDL License to drive a bucket truck.
He needs a CDL to drive a fire truck on the highway. Most heavy duty truck mechanics have that license. In my state (CT) you can drive a fire truck with a Class B (straight truck CDL) or what we call a Q endorsement which is a fire apparatus only endorsement of your normal license. You take the Class B test and they'll give you just the Q. I don't think its as "governed" as the CDL is. On another note the Q endorsement lets you drive any FD truck from the little ones to the 80,000 lb ladder truck if you get checked out on it. I understand the intent of the law or allowance I should say, but there are considerations,hazards, and skill about handling that kind of weight which was covered in my Class A CDL class that weren't really mentioned on my Q. If that ladder was a commercial vehicle you would need an A license for that weight.
No, not to insure it just to drive it. You can insure it and let someone else drive it as long as they have their Class A CDL.
If it's a truck which anyone else would be required to have a CDL to drive, then yes.
If the vehicle requires a CDL in service, it'll require a CDL for the test drive.
If they're paid for that work, they must log it.
Can I drive a farm dumptruck without a cdl in Washington State
No, just to drive it.
Yes, but you can't drive it.
Depends. You can drive up to a Class 6 truck (up to 26,000 lbs. GVWR) without a CDL. Class 7 or Class 8 trucks require a CDL.
It depends on the model. You need a CDL to drive one that bends in the middle or is over a certain length
