Connecticut motor carrier statistics
Connecticut ranks #31 of the 50 states and DC by active motor carrier registrations, with 21,557 active carriers — 1.0% of the U.S. total. 6,173 of them (28.6%) hold operating authority. Computed from FMCSA's census snapshot of 2026-09-04 10:47 UTC.
Among Connecticut's 6,173 authority holders, 3,191 (51.7%) report a single power unit and 304 (4.9%) report a fleet of 10 or more. 1,426 (23.1%) last filed an MCS-150 biennial update before September 2024 — below the national 25.9%.
Registration overview
| Measure | Connecticut | Share | U.S. share |
|---|---|---|---|
| Active registrations | 21,557 | 1.0% of U.S. | rank #31 of 51 |
| With operating authority | 6,173 | 28.6% | 32.6% |
| Hazmat-registered | 2,095 | 9.7% | 7.0% |
“Share” is the measure as a percentage of Connecticut's active registrations; “U.S. share” is the same percentage computed nationally, so the two columns are directly comparable.
Operation type
| Operation | Carriers | Connecticut | U.S. |
|---|---|---|---|
| Interstate | 8,391 | 38.9% | 31.0% |
| Intrastate, hazmat | 684 | 3.2% | 2.1% |
| Intrastate, non-hazmat | 12,436 | 57.7% | 66.7% |
| Not reported | 46 | 0.2% | 0.2% |
Percentages are of active registrations. Interstate (census code A) carriers cross state lines; intrastate carriers operate only within Connecticut.
Fleet size
| Power units | Carriers | Connecticut | U.S. |
|---|---|---|---|
| 1 power unit | 3,191 | 51.7% | 49.8% |
| 2–9 power units | 1,719 | 27.8% | 26.8% |
| 10–49 power units | 253 | 4.1% | 5.0% |
| 50 or more power units | 51 | 0.8% | 1.2% |
| None reported (0 or blank) | 959 | 15.5% | 17.2% |
Percentages are of Connecticut's 6,173 active authority holders. Power-unit counts are self-reported on the MCS-150 and are not validated by FMCSA; a small number of records carry implausible values, so treat the top bucket as an upper bound.
MCS-150 filing currency
| Last recorded MCS-150 update | Carriers | Connecticut | U.S. |
|---|---|---|---|
| September 2024 or later | 4,325 | 70.1% | 66.0% |

| No date recorded in the census | 422 | 6.8% | 8.1% |
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.
