Connecticut motor carrier statistics
Connecticut ranks #31 of the 50 states and DC by active motor carrier registrations, with 21,734 active carriers — 1.0% of the U.S. total. 6,167 of them (28.4%) hold operating authority. Computed from FMCSA's census snapshot of 2026-10-21 13:18 UTC.
Among Connecticut's 6,167 authority holders, 3,163 (51.3%) report a single power unit and 312 (5.1%) report a fleet of 10 or more. 1,503 (24.4%) last filed an MCS-150 biennial update before October 2024 — below the national 27.0%.
Registration overview
| Measure | Connecticut | Share | U.S. share |
|---|---|---|---|
| Active registrations | 21,734 | 1.0% of U.S. | rank #31 of 51 |
| With operating authority | 6,167 | 28.4% | 32.3% |
| Hazmat-registered | 2,064 | 9.5% | 6.7% |
“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 | 8,478 | 39.0% | 30.9% |
| Intrastate, hazmat | 0 | 0.0% | 0.01% |
| Intrastate, non-hazmat | 13,211 | 60.8% | 68.8% |
| Not reported | 45 | 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 | 3,163 | 51.3% | 49.4% |
| 2–9 power units | 1,743 | 28.3% | 27.1% |
| 10–49 power units | 260 | 4.2% | 5.0% |
| 50 or more power units | 52 | 0.8% | 1.3% |
| None reported (0 or blank) | 949 | 15.4% | 17.2% |
Percentages are of Connecticut's 6,167 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. |

| No date recorded in the census | 453 | 7.3% | 8.7% |
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.
