Starting a dump truck business: authority, weight limits, and costs
A dump truck business usually starts as an intrastate operation: the loads are local, so state rules decide most of the paperwork. You register with your state for intrastate authority, add a USDOT number where your state requires one, and watch the federal weight limits the moment you touch the Interstate.

Why dump trucking is a state-first business
Dump truck work is short haul by design: aggregate, sand, and demolition debris move from a pit or plant to a job site, and the whole run often stays inside one state. An operation that never crosses a state line and hauls no interstate freight does not need federal operating authority, though it still answers to its state's intrastate authority rules and needs a USDOT number in the states that require one for intrastate carriers.
So your first two lookups are state lookups. Check what your state calls intrastate authority and what it charges in the intrastate authority by state table, then confirm whether your state makes in-state carriers register federally in state DOT number requirements. Cross a state line for hire, even once, and the standard federal steps apply: a USDOT number plus interstate operating authority.
The weight limits that shape every load
Dump trucks earn by the ton, so the weight rules are the business model. On the Interstate System, federal law sets the ceiling:
State-by-state legal size limits and single-trip permit base fees live in the oversize permit costs by state table. The axle-weight limits and weight-tiered overweight fees a heavy dump load actually triggers render in full on each live state's oversize and overweight permits page, such as Texas.
The costs that stack on top of the truck
The truck is the big check, but the compliance stack has its own line items: state registration, insurance sized to your radius and cargo, and the federal heavy vehicle use tax for trucks at or above the Form 2290 threshold. The Form 2290 guide covers the filing calendar, and the full budget walkthrough lives in how much it costs to start a trucking company. For the coverage side of that stack, including why dump work prices differently, see dump truck insurance.
Dump work shares its shape with another local, equipment-heavy trade: if your plan leans toward recovery work instead of aggregate, the tow truck business guide maps that state-first path too.
