The Portsmouth carrier base in numbers

What the local carrier data shows

Of the carriers registered here, 13 (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 An outdated or inactive USDOT record can also create issues with brokers, shippers, insurers and other counterparties.

Single-truck operators make up 40% of carriers here, well below the 64% national share, with a further 49% running two to ten units.

11 local carriers, 11% 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.

What Portsmouth carriers actually haul
