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

Thompsongas LLC (USDOT 2812287, MC-938205) is an active motor carrier based in Frederick, 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: 1,210 power units and 787 drivers (621 with CDLs). Power units count straight trucks as well as tractors, so they can exceed the tractor count. It reported 16,264,256 miles for 2023 on its MCS-150. Cargo classes declared: liquids / gases. It is also classified as a private carrier of its own goods. FMCSA has not issued it a safety rating (no compliance review on record). In the last 24 months it had 635 roadside inspections, 37 of them (5.8%) with an out-of-service order; 487 hazmat inspections and 9 hazmat out-of-service orders; 15 reportable crashes (0 deaths, 5 injuries); a crash on record does not by itself mean the carrier caused it. Registration (MCS-150) last updated September 19, 2024, more than two years ago and past FMCSA's two-year update requirement, so the fleet, driver and cargo figures above may be out of date.

Key facts

Fleet size	500+ power units Power units, banded. source
FMCSA safety rating	Not rated Satisfactory, Conditional or Unsatisfactory after an FMCSA compliance review; most carriers have never had one and are not rated. source
Rating age	Not rated How old the FMCSA safety rating is. A rating reflects one compliance review on that date, not current performance; old ratings say little about the carrier today. source

Operation	Interstate Interstate, intrastate hazmat or intrastate non-hazmat, as declared on the MCS-150. source
