Each field from the public registration, and what it means when you’re vetting this carrier.
- USDOT number 256299
- 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 ROBERTSON'S READY MIX LTD.
- MC number MC 1040325
- An MC (docket) number means the company applied for interstate operating authority to haul regulated freight for hire or to broker loads. Brokers and shippers usually check MC authority before booking.
- 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 Interstate
- Interstate carriers can haul freight across state lines and fall under the full federal safety rules (FMCSRs).
- Fleet size 1,239 power units, 1,239 drivers
- ROBERTSON'S READY MIX LTD self-reports 1239 power units (trucks and tractors), which makes it a large fleet. Fleet counts come from the carrier's own MCS-150 filing and aren't independently audited.
- Last MCS-150 update Jul 22, 2025
- The MCS-150 is the registration form where carriers report their address, fleet size, and operations. ROBERTSON'S READY MIX LTD last filed it on Jul 22, 2025. That's within FMCSA's two-year update requirement, so the company details here are reasonably current.
