Becoming a Dump Truck Broker (Subbing Overflow Legally)
May 19, 2026·8 min read
Short answer
You can broker dump truck work to other operators once you have MC Authority as a broker (separate filing) or a subcontractor agreement structure. Typical brokered margin is 8–15%.
The natural next step after your third truck is brokering out the fourth, fifth, and sixth loads to trusted operators — and taking a margin for the relationship.
The two legal paths
- Register as a property broker with FMCSA (MC broker authority, $75k bond, separate from carrier authority)
- Contract subs under your carrier authority as subcontracted haulers with a written subcontract, additional-insured status, and W-9 on file
