Reading the Watertown figures
Of the carriers registered here, 21 (14%) are carrying an MCS-150 older than 24 months, which is well below 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 An outdated or inactive USDOT record can also create issues with brokers, shippers, insurers and other counterparties.
32 local carriers, 22% of the base, are flagged for hazardous materials, well above the national 7%. Hazmat operations answer to a shorter corrective-action clock if a safety audit goes against them.
Single-truck operators make up 43% of carriers here, well below the 64% national share, with a further 49% running two to ten units.
