UCR Fleet-Size Brackets
Also known as: Fleet-Size Brackets, Vehicle Brackets, UCR Bracket Schedule

Definition
UCR fleet-size brackets are the six tiers in the UCR fee schedule, defined by the number of commercial motor vehicles a carrier operates: 0–2, 3–5, 6–20, 21–100, 101–1,000, and 1,001 or more. The fee rises with each bracket and is set nationally by FMCSA through rulemaking under 49 USC §14504a and stays in place until a later rulemaking changes it (91 FR 56063), so it does not vary by state. Picking the right bracket is a key step in filing UCR correctly. For 2027 the federal fee runs from $55 for 0–2 vehicles to $54,165 for 1,001 or more (49 CFR 367.50).
