UCR bracket B6: $54,165 for 2027

What $54,165 buys, per truck

There is no upper bound to this bracket, so the per-vehicle cost keeps falling as the fleet grows: $54.11 a vehicle at 1,001 vehicles, $27.08 at 2,000 and $10.83 at 5,000. For context the smallest bracket, B1, costs a two-truck carrier $27.50 a truck, so the largest carriers pay a fraction of the per-vehicle rate the smallest ones do.

The edges of bracket B6

Below: there is nothing below B6. Zero vehicles is still B6.

Above: one vehicle past puts you in bracket B1 (0–2 vehicles) at $55, a step of $-54,110. The step is modest at this end of the schedule; the brackets widen sharply further up.

Past a thousand: the top of the schedule

For carriers with more than 1,000 commercial motor vehicles, UCR is $54,165 a year, paid once through the base state regardless of how many states the fleet operates in. The per-vehicle figure keeps falling without limit — $54.11 at the bottom of the bracket — because the schedule has no B7. The 2027 increase here was the largest in absolute terms, $9,329, or 20.8 percent — in line with the 20 percent average across the schedule.

Registration years and sources

2027 registration opened on October 1, 2026. The 2027 fee also applies to every later registration year until FMCSA adopts a new table by rule. Brackets did not change between the two years shown; only the dollar amounts did, by 20 percent on average across the schedule.

Who registers in bracket B6

The largest national carriers and private fleets in the country. Anyone in the bracket who is engaged in interstate commerce to any extent must register; the rule is not about how far or how often.
