Frequently asked questions

About trucking companies in Baltimore, MD

Which trucking company in Baltimore has the biggest fleet?

COWAN SYSTEMS LLC leads the Baltimore, MD ranking with 1882 power units on its most recent MCS-150 filing. Its complete public workup — risk flags, score breakdown, insurance filing history, and record timeline — lives at https://mclookup.com/carrier/548880.

How many motor carriers operate out of Baltimore?

953 active carriers list a Baltimore, MD headquarters address in the FMCSA census (after filtering for realistic fleet data). The top 100 by fleet size are ranked on this page; the rest are searchable by USDOT or MC number.

How concentrated is trucking capacity in Baltimore?

Among the 100 largest Baltimore fleets, the top 10 hold 51% of the 11,667 combined power units, and the median fleet runs 57 trucks. 18 of these carriers operate 100+ power units, 82 run 25-99, and 0 run 5-24. 0% hold an MC number, meaning for-hire interstate authority rather than private carriage.

What does the ranking on this page measure?

Position reflects self-reported power units — tractors, straight trucks, and buses, excluding trailers — from each carrier's MCS-150. A plausibility filter (driver-to-truck ratio between 0.3 and 5.0) removes registrations with obviously bad data before ranking.

What shows up on each carrier's linked profile?

Every row links to that carrier's public record page: red and caution risk flags with point deductions, a category-by-category score breakdown, the month-over-month FMCSA record timeline, insurance filing history, and any shared-contact links to other carriers — all from federal data, refreshed on a rolling ~48-hour cycle.

Do I need an account to vet a Baltimore carrier?

No — the public record pages are open. A free account adds the deeper workup: BASIC percentile detail, crash-by-crash records, live insurance verification against federal minimums, and watchlist monitoring with change alerts.
