UCR

Definition

UCR — Unified Carrier Registration — is an annual registration program administered by the Unified Carrier Registration Plan under 49 USC §14504a and 49 CFR Part 367. Every for-hire and private interstate motor carrier, broker, and freight forwarder pays a fee scaled by fleet size to their base state. The 2026 fee tiers range from Bracket 1 (~$46 for 0–2 vehicles) to Bracket 6 (~$44,639 for 1,001+ vehicles). The registration year matches the calendar year, with December 31 as the deadline. Enforcement begins January 1 — out-of-service orders can issue at weigh stations against carriers without active UCR registration.
