Fleet size and carrier records in Williston
Single-truck operators account for 48% of the Williston carrier base, compared with 64% in the national comparison used here. At that size the owner may handle much of the compliance administration personally. Owner-operators who are subject to Part 382 generally participate in a compliant random-testing consortium or similar third-party program.
Hazardous materials carry more weight here than they do nationally: 91 carriers (14%) hold a hazmat flag against 7% across the country. That adds placarding, shipping papers, security plans and endorsement checks to the standard file.
Filing currency is the standout number here. 221 carriers, 34% of the local base, last filed an MCS-150 more than two years ago, below the national picture of 38%. The biennial update is required on the applicable filing cycle even when nothing has changed, and missing a required update can affect the carrier’s USDOT record.
