Verified Oct 22, 2026 against FMCSA Company Census File (data.transportation.gov)

D M Bowman Inc (USDOT 135530, MC-138438) is an active motor carrier based in Williamsport, Maryland that FMCSA's census classifies as for-hire and that declares hazardous materials on its MCS-150. Operation: interstate. Operating authority: active for-hire authority (MC). Fleet: 265 power units and 244 drivers (244 with CDLs). Power units count straight trucks as well as tractors, so they can exceed the tractor count. It reported 17,322,019 miles for 2025 on its MCS-150. Cargo classes declared: chemicals, liquids / gases, dry bulk commodities, general freight, intermodal containers, building materials, construction, machinery, large objects, metal: sheets, coils, rolls, logs, poles, beams, lumber, agricultural / farm supplies, grain, feed, hay, beverages, paper products, U.S. mail. It is also classified as a private carrier of its own goods. FMCSA safety rating: satisfactory, from a compliance review on July 9, 2009, 17 years ago; it reflects that review, not current performance. In the last 24 months it had 274 roadside inspections, 34 of them (12.4%) with an out-of-service order; 7 hazmat inspections; 18 reportable crashes (3 deaths, 7 injuries); a crash on record does not by itself mean the carrier caused it. Registration (MCS-150) last updated July 6, 2026.

Key facts

Fleet size	100–499 power units Power units, banded. source
FMCSA safety rating	Satisfactory Satisfactory, Conditional or Unsatisfactory after an FMCSA compliance review; most carriers have never had one and are not rated. source

Registration update overdue	No The MCS-150 was last updated more than two years ago, past FMCSA's two-year update requirement; fleet, driver and cargo figures may be out of date. source
Operation	Interstate Interstate, intrastate hazmat or intrastate non-hazmat, as declared on the MCS-150. source

USDOT number: The registration number every interstate (and many intrastate) commercial carrier holds.

MCS-150: The registration form carriers file with FMCSA and must update at least every two years; fleet, drivers, cargo and the hazmat flag on this site come from it, as the carrier declared them.

Safety rating: FMCSA's result after an on-site compliance review: Satisfactory, Conditional or Unsatisfactory. A rating is not refreshed unless FMCSA reviews the carrier again, so many are years old; each profile gives the review date. Most carriers have never been reviewed and are not rated; that is not a bad mark.

Power units: Trucks and tractors that pull or carry freight.

Reportable crash: A crash involving the carrier's vehicle with a death, an injury treated away from the scene or a vehicle towed away. FMCSA records it whoever was at fault.

Cargo classes: Self-declared on the MCS-150 from FMCSA's fixed list. Some carriers tick most of the list, so a long list means 'declared', not 'specialises in'; the hazmat flag does not say which hazardous materials.
