“Share” is the measure as a percentage of District of Columbia's active registrations; “U.S. share” is the same percentage computed nationally, so the two columns are directly comparable.

FMCSA requires a biennial MCS-150 update. The cutoff above is the first day of the month 24 months before this page was rendered. A stale census date is a strong signal but not proof of a missed filing — check a specific USDOT number with the MCS-150 update checker.
