Yes. Class B CDL applies to all single vehicles with a GVW in excess of 26,000 lbs.
Go to a truck driving school. You're not going to learn how to drive a Class 8 truck by reading about it on this website.
The exact same thing as the first drive axle.
#1 axle is the steer axle, #2 axle is the front drive axle, #3 axle is the rear drive axle.
Truck classification isn't concurrent with the license required to drive them. A single axle water truck could be a Class 5, 6, 7, or 8 truck, depending on the vehicle GVWR. A Class 7 or Class 8 truck would require a (minimum) Class B CDL.
Whoever answered this question is WRONG. If you are talking a "single axle" (One steering axle and one drive axle with 2 tires on the steering axle and 4 on the drive axle) you do not need any special license
From the center of steer axle to center of rear axle on trailer. If you want just the truck it's the center of steer axle to center of rear drive axle.
There's no such thing as a one axle truck. There has to be a minimum of two axles. "Single axle" if a term referring to a truck with only a single drive axle, and doesn't count the steer axle. Same with "tandem axle", "tri axle", "quad axle", and "quint axle".
The power unit has a steer axle, and only one drive axle.
Not enough information to answer. What type, is it a straight truck or tractor trailer, how many axles, what class vehicle, etc. would be needed to give you an answer. With weight laws in the US, a single drive axle truck rated at 26,000 lbs. gross vehicle weight could carry up to five tons, while a Class 7 single drive axle truck rated at 33,000 - 35,000 lbs. could carry up to eight tons. A tandem axle straight truck would be in the vicinity of 12 to 13 tons, and a standard, five axle, semi tractor and trailer can range from 23 to 25 tons of legal payload.
A "hot shot" is simply a single axle truck pulling a multiple axle trailer. It could be anything from a 1 ton pickup up to a Class 8 truck (technically, any single axle would be rated as Class 7, but there's a big difference between a truck which is a true Class 7 truck and a truck which is basically a Class 8 truck with one less axle). So, what exactly are you looking for? Try car dealerships, truck dealerships, Auto Trader, Truck Trader, Heavy Equipment Trader, Craigslist, Ebay Motors, etc.
It's a dump truck with four axles--the steer axle in front and three axles in back. One of them moves up and down via a control in the cab, so the tires aren't on the road if the truck's not loaded. A tri-axle dump truck carries more weight than a one-axle or two-axle truck.
The length from the middle of the steer wheels to the center point between the drive tandems (for a tandem truck) or center of the single drive axle (on a single axle truck).
