The Miami carrier base in numbers

Reading the Miami figures

Of the carriers registered here, 9,185 (54%) are carrying an MCS-150 older than 24 months, which is well above the national rate of 38%. That filing is required on the applicable biennial cycle even when nothing about the business has changed. An outdated or inactive USDOT record can also create issues with brokers, shippers, insurers and other counterparties.

Single-truck operators make up 77% of carriers here, well above the 64% national share, with a further 21% running two to ten units.

2,110 of the local carriers, 12% 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.
