What R J GRONDIN & SONS’s FMCSA record shows
Each field from the public registration, and what it means when you’re vetting this carrier.
- USDOT number 571593
- 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 R J GRONDIN & SONS.
- 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 Active
- FMCSA lists this USDOT number as active. Active status alone doesn't confirm current insurance or operating authority; those are separate checks.
- Operation type Intrastate Hazmat
- Intrastate carriers are registered to operate within a single state. Booking one for a load that crosses state lines is a compliance red flag.
- Fleet size 53 power units, 40 drivers
- R J GRONDIN & SONS self-reports 53 power units (trucks and tractors), which makes it a mid-size fleet. Fleet counts come from the carrier's own MCS-150 filing and aren't independently audited.
- Last MCS-150 update Sep 25, 2025
- The MCS-150 is the registration form where carriers report their address, fleet size, and operations. R J GRONDIN & SONS last filed it on Sep 25, 2025. That's within FMCSA's two-year update requirement, so the company details here are reasonably current.
