Reading the Gillette figures
Single-truck operators make up 48% of carriers here, well below the 64% national share, with a further 44% running two to ten units.
81 local carriers, 14% of the base, are flagged for hazardous materials, above the national 7%. Hazmat operations answer to a shorter corrective-action clock if a safety audit goes against them.
68 of the local carriers, 11% of the base, took their registration out in 2025 or later, close to the national figure of 12%. Many carriers first registered in 2025 or later may still be within FMCSA’s New Entrant Safety Assurance Program, depending on their registration date and status. New-entrant carriers are subject to FMCSA’s safety-audit and corrective-action process.
