UCR Tier 1 vs Tier 2: which bracket applies to your fleet

UCR Tier 1 covers carriers with 0-2 power units and costs $80 in 2026. Tier 2 covers carriers with 3-5 power units at $237. Trailers do not count, only power units. Fleet size is locked as of July 1 of the year preceding the registration year — so the 2026 registration (paid by December 31, 2025) is calculated from your July 1, 2025 fleet count.

How to count your power units

UCR counts only commercial motor vehicles operated in interstate commerce as of July 1 of the prior year. Definitions:

  • Counted: trucks, tractors, buses (any self-propelled CMV used in interstate commerce)
  • Not counted: trailers, dollies, converter gears, intrastate-only vehicles, vehicles in a fleet but not yet placed in service
  • Lease wrinkle: a leased-on owner-operator's truck counts toward the lessee carrier's UCR, not the owner-operator's. Reverse for trip-leased equipment held under the carrier's authority.
  • Multi-MC carriers: if one parent operates trucks under two MC numbers, each MC files its own UCR with its own count of trucks operating under that MC during the prior year.

Tier-2 jump: most common audit trigger

UCR auditors typically pull a carrier's IRP apportioned-plate roster and 2290 schedule list as of July 1 of the prior year and reconcile against the UCR fleet count. The bracket boundary at 3 trucks (Tier 1 → Tier 2) is the single most common audit trigger because owner-operators commonly add their second and third trucks mid-year and forget to update UCR.

If an audit shows under-reporting, the carrier owes the higher tier's fee plus a per-state penalty (typical $100-$500 per state) plus interest. The audit can also generate a CSA Driver Fitness BASIC entry that increases roadside-inspection probability for 24 months. Filing accurate counts at $237 instead of underreporting at $80 is always cheaper.

Frequently asked questions

Do trailers count toward my UCR fleet size?

No. UCR counts power units only — trucks, tractors, buses. Trailers, dollies, and converter gears are not counted toward the bracket. Brokers and freight forwarders pay UCR as Tier 1 regardless of any equipment they own.

What if my fleet grew from 2 to 4 trucks during the year?

You report fleet size as of July 1 of the year before the registration year. So for the 2026 UCR registration (paid by Dec 31, 2025), you count the trucks you operated as of July 1, 2025. Adding trucks after July 1 does not bump you into the next bracket until the following year — but UCR auditors do verify counts against IRP/IFTA records, so accurate reporting matters.

Can a leased truck be counted on someone else's UCR?

Yes. The carrier whose authority the truck operates under counts it for UCR. If an owner-operator leases their truck to a motor carrier under a 49 CFR 376 lease, the motor carrier counts the truck on its UCR — not the owner-operator. The owner-operator only files UCR if they have their own MC authority.
