- 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.

- Fleet size 170 power units, 125 drivers
- INTERMOUNTAIN SLURRY SEAL INC self-reports 170 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.
