Before you book a load with PROMASTER INSTALLATIONS LLC
- Make sure the MC has active broker authority — a carrier-only MC booking loads is a double-brokering red flag.
- Confirm the $75,000 broker bond or trust (BMC-84 / BMC-85) is on file.
- Call the phone number listed with FMCSA, not the one in an email or load-board post.
- Get a signed rate confirmation before you move the load.
