What SUBSURFACE INVESTIGATIONS INC’s FMCSA record shows

Each field from the public registration, and what it means when you’re vetting this carrier.

USDOT number 337321
The USDOT number is FMCSA's permanent ID for this company. It never changes, even when the business renames, moves, or changes owners, so it's the most reliable way to identify SUBSURFACE INVESTIGATIONS INC.
MC number None on file
No MC number is on file. That's normal for private fleets hauling their own goods and for intrastate-only carriers, but a company with no MC number can't legally haul regulated interstate freight for hire.
Operating status Inactive
FMCSA lists this USDOT number as inactive. Inactive carriers shouldn't be dispatched; confirm the company has reactivated before booking a load.
Operation type Interstate
Interstate carriers can haul freight across state lines and fall under the full federal safety rules (FMCSRs).
Fleet size 2 power units, 2 drivers
SUBSURFACE INVESTIGATIONS INC self-reports 2 power units (trucks and tractors), which makes it a small fleet. Fleet counts come from the carrier's own MCS-150 filing and aren't independently audited.
