Depends on the GVWR of the vehicle. 26,000 lbs. or less, and the answer is no (unless you're hauling something which requires a hazmat endorsement, such as contaminated soil). GVWR of more than 26,000 lbs, and the answer is yes.
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.
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.
A quad axle dump truck is a tandem axle dump truck, with additional lifting pusher and/or tag axles. The most common configuration is two steerable lift axles in front of the drive tandems, although some will have one pusher in front of the tandems, and a tag behind the tandems.
Three - the two drive axles, and the steer axle.
That's going to depend on the dump truck's configuration. It could be a single axle, tandem, tri-axle, quad axle, quint axle, centipede, frameless end dump, framed end dump, etc.
A quad axle dump truck is a tandem axle dump truck, with additional lifting pusher and/or tag axles. The most common configuration is two steerable lift axles in front of the drive tandems, although some will have one pusher in front of the tandems, and a tag behind the tandems.
The amount of dirt a dump truck can hold depends on the size of the dump truck. The average tri axle dump truck can hold 12 cubic yards of dirt, and a quad axle can hold 14.
A quint axle dump truck is larger than a quad axle dump truck. The quint axle configuration includes five axles, which allows for a higher payload capacity and increased stability compared to a quad axle truck, which has four axles. This additional axle in quint axle trucks helps distribute weight more effectively, making them suitable for heavier loads.
A tandem dump truck is as normal as any other dump truck. Tandem simply indicates that it has two drive axles (as opposed to a single axle, which only has one). A tandem dump is typically allowed to gross at 54,000 lbs. From there, some dump trucks have additional axles (lift axles) which allow them to haul more weight. They're named in accordance with the number of axles behind the cab (i.e., not including the steer axle). So a tandem dump with a single lift axle would be referred to as a tri-axle, with two lift axles it would be referred to as a quad axle dump, with three lift axles it would be referred to as a quint axle dump.... at four lift axles, they're typically referred to as 'centipedes'.
A dump truck with two drive axles.
Tandem axle dump truck. In some states, you may be able to put up to 15 tons on a single axle with an additional lifting tag axle.
What type and configuration of dump truck? A single axle dump truck is going to be much shorter than a centipede, and you could be referring to any dump truck in between the two extremes, as well.
