Roadside inspections Oct 18, 2024 – Oct 18, 2026
No roadside inspections in this period.
How these rates are calculated
Period: Oct 18, 2024 – Oct 18, 2026. Vehicle rate = vehicle inspections with a vehicle out-of-service order ÷ vehicle inspections (levels 1, 2, 5 and 6). Driver rate uses levels 1, 2, 3 and 6. The Texas average covers 347,521 vehicle and 460,200 driver inspections of all Texas-based carriers in this period. It mixes every type of operation, so compare with care; rates based on a handful of inspections say little. FMCSA's own SMS measures are weighted differently: SMS profile ↗ · SAFER snapshot ↗

No violations recorded in roadside inspections in the last 24 months.

Questions about CARROLL STONE & ROCK COMPANY INC
What does CARROLL STONE & ROCK COMPANY INC's operating authority allow?
FMCSA records show no active operating authority for CARROLL STONE & ROCK COMPANY INC (MC400344), so it may not haul regulated interstate freight for hire or broker loads under these dockets.
Which information about CARROLL STONE & ROCK COMPANY INC is old or missing?
Operating authority is the last known status from the FMCSA snapshot of May 14, 2026, not a current check. No insurance filings were found in the public data. There are too few vehicle inspections in the last 24 months to judge the out-of-service rate. FMCSA has not issued a safety rating, which means no compliance review is on record, not that the carrier is unsafe. The MCS-150 was last updated May 2, 2019, so fleet size and contact details may be out of date.
What should I verify before booking CARROLL STONE & ROCK COMPANY INC?
Confirm the authority and insurance on the Motus record for USDOT 400344. Call the company back on the phone number on file, (817) 596-0102, not a number from an email or load board message. Check that the MC number the dispatcher gave you matches MC400344, and ask the insurer for a certificate of insurance naming you as certificate holder.
