Our read on this carrier
Worth a Closer Look
A few things are worth checking before you hire this carrier or give them a load.
Looks fine ! Worth checking × A real concern
1 other trucking company use this same address
This can be perfectly normal (a shared business park or mailbox) — but it can also point to related or shell companies. Confirm the address if anything else looks off.
Trucks fail roadside inspections often (109%)
109% of this carrier's roadside inspections ended with a truck or driver ordered off the road — well above the ~21% national average. Higher means more safety problems.
Not on any U.S. sanctions list
This carrier's name doesn't appear on the U.S. Treasury sanctions blocklist — clear to work with on that basis.
Licensed and authorized to operate
The FMCSA lists this carrier as having active operating authority right now.
No history of a revoked license
This carrier's operating authority has not been revoked and re-registered.

These checks use public U.S. government records — the carrier's license status, safety-inspection and crash history, ownership links, and the U.S. Treasury sanctions list — refreshed automatically. A flag doesn't prove wrongdoing; it's a prompt to verify before you do business.
