Idaho motor carrier statistics
Idaho ranks #34 of the 50 states and DC by active motor carrier registrations, with 13,872 active carriers — 0.6% of the U.S. total. 5,224 of them (37.7%) hold operating authority. Computed from FMCSA's census snapshot of 2026-09-04 10:47 UTC.
Among Idaho's 5,224 authority holders, 2,382 (45.6%) report a single power unit and 376 (7.2%) report a fleet of 10 or more. 1,113 (21.3%) last filed an MCS-150 biennial update before September 2024 — below the national 25.9%.
Registration overview
| Measure | Idaho | Share | U.S. share |
|---|---|---|---|
| Active registrations | 13,872 | 0.6% of U.S. | rank #34 of 51 |
| With operating authority | 5,224 | 37.7% | 32.6% |
| Hazmat-registered | 1,084 | 7.8% | 7.0% |
“Share” is the measure as a percentage of Idaho's active registrations; “U.S. share” is the same percentage computed nationally, so the two columns are directly comparable.
Operation type
| Operation | Carriers | Idaho | U.S. |
|---|---|---|---|
| Interstate | 6,367 | 45.9% | 31.0% |
| Intrastate, hazmat | 216 | 1.6% | 2.1% |
| Intrastate, non-hazmat | 7,287 | 52.5% | 66.7% |
| Not reported | 2 | 0.01% | 0.2% |
Percentages are of active registrations. Interstate (census code A) carriers cross state lines; intrastate carriers operate only within Idaho.
Fleet size
| Power units | Carriers | Idaho | U.S. |
|---|---|---|---|
| 1 power unit | 2,382 | 45.6% | 49.8% |
| 2–9 power units | 1,792 | 34.3% | 26.8% |
| 10–49 power units | 308 | 5.9% | 5.0% |
| 50 or more power units | 68 | 1.3% | 1.2% |
| None reported (0 or blank) | 674 | 12.9% | 17.2% |
Percentages are of Idaho's 5,224 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 | Idaho | U.S. |
|---|---|---|---|
| September 2024 or later | 3,684 | 70.5% | 66.0% |

| No date recorded in the census | 427 | 8.2% | 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.
