UCR is the annual federal fee that every interstate motor carrier, broker, and freight forwarder pays through their base state to fund safety and economic enforcement programs.
Direct answer
California interstate motor carriers, brokers, and freight forwarders file UCR through California as their base state for the registration year. Bracket A (1–2 power units) is $46 for 2026; tiers scale up to Bracket F (1,001+ vehicles). FastUCRFiling completes the filing same business day with confirmation back from the UCR Plan board.

What UCR is and why California carriers file it
Unified Carrier Registration (UCR) is the federal program established under 49 USC §14504a that requires every interstate motor carrier, freight broker, and freight forwarder to register and pay an annual fee based on fleet size. Funds collected are distributed to participating states to support FMCSA enforcement programs — weigh-station staffing, roadside inspections, and the New Entrant Safety Audit program.
California is a participating UCR state. California-based carriers file through California as their base state, but the registration is recognized in all participating UCR jurisdictions. California is the largest carrier-registration state in the US and runs the most rigorous state-level enforcement layer in the country.
2026 UCR fee schedule
The UCR Plan publishes the annual fee schedule each fall. For 2026, the brackets are: Bracket A (1–2 power units): $46. Bracket B (3–5): $138. Bracket C (6–20): $275. Bracket D (21–100): $957. Bracket E (101–1,000): $4,558. Bracket F (1,001+): $44,508. Brokers and freight forwarders pay Bracket A regardless of fleet size since they don't operate vehicles directly.
California carriers in Bracket A make up the largest filing volume — most owner-operators and small fleets fall into the 1–2 power unit category. Tier escalation is based on the carrier's combined power units across all states; adding a single tractor that pushes you over a bracket threshold means a higher fee for that registration year.
Filing window and California enforcement
The 2026 UCR filing window opens October 1, 2025 and closes the day the carrier files (filing late incurs no extra UCR fee, but participating-state enforcement can pull a carrier out of service the moment registration lapses past December 31). California enforces UCR at every staffed weigh station via the L&I database query — the inspector types your USDOT and sees UCR status in real time.
The penalty profile in California mirrors most participating states: out-of-service order at the weigh station plus a per-offense fine that scales by jurisdiction (typically $100–$500 per occurrence). Repeat offenses compound, and a habitually-lapsed UCR shows up on the carrier's CSA Safety Fitness profile, which brokers and shippers query before tendering loads.
California interstate carrier base — context
California's 62,000+ registered motor carriers (FMCSA SAFER) collectively file UCR every year — making the state a top-volume contributor to the UCR Plan's revenue. Beyond UCR itself, California carriers running through corridors like I-5, I-10, I-15 typically also need: federal MCS-150 currency, current insurance filings (BMC-91), Form 2290 stamped Schedule 1 if any vehicle is 55,000+ lbs, and (where applicable) state-level surcharges. CA Number from CHP (any commercial vehicle 10,001+ lbs); CARB Clean Truck Check annual; California Motor Carrier Permit for intrastate for-hire — all separate from federal UCR and MCS-150
FMCSA Western Service Center (Lakewood, CO) oversees FMCSA-side enforcement actions for the state, but UCR itself is administered by the UCR Plan board (a multi-state compact) and the home state's UCR coordinator. Filing through FastUCRFiling routes through the UCR Plan's online registration portal and produces a confirmation back to the carrier within one business day.
What makes California different
California is the largest carrier-registration state in the US and runs the most rigorous state-level enforcement layer in the country. The CHP commercial enforcement program operates 7 fixed weigh stations plus roving inspections, and CARB emissions agents work independently of CHP. The Ports of Los Angeles and Long Beach handle 40% of US containerized imports — drayage carriers serving them face the most expensive insurance market in the country plus stringent Clean Truck Program rules. The Grapevine downgrade on I-5 is the highest-violation brake-inspection corridor in the state.
- CA Number (CA #) from CHP — required for any commercial vehicle 10,001+ lbs operating in California
- CARB emissions compliance — diesel trucks 2010+ engine year, Clean Truck Check annual inspections for 14,000+ lb GVW
- State-level drug & alcohol testing program reporting in addition to federal Clearinghouse
- Separate CARB registration (TRUCRS) for in-state fleets running older equipment

Running UCR Registration in California? You probably also need BOC-3 Filing in California. A BOC-3 designates a process agent in every US state so the FMCSA has a local point for service of legal process on your operating authority.
Other filings California carriers need
BOC-3 Filing
$75 flat (lifetime)
A BOC-3 designates a process agent in every US state so the FMCSA has a local point for service of legal process on your operating authority.
USDOT & MC Authority
From $299 (plus FMCSA $300 filing fee)
A USDOT number is the FMCSA safety identifier every commercial motor vehicle operator needs; MC operating authority is the for-hire interstate license that lets you legally haul freight for compensation.
MCS-150 Update
$75 service fee
The MCS-150 is FMCSA's biennial check-in form for every USDOT holder — fleet size, driver count, operational mileage, and safety contact information.
Form 2290 (HVUT)
From $149
Form 2290 is the federal Heavy Vehicle Use Tax (HVUT) return for trucks 55,000 lbs taxable gross weight or higher. Filing produces the stamped Schedule 1 — proof of payment that state DMVs require for truck registration renewal.
State Trucking Permits
Varies by program (NY HUT $19+, KY KYU quarterly, NM WDT, OR weight-mile, CT HUF)
State trucking permits cover any state-specific authorization, weight-distance tax, or commercial surcharge that stacks on top of federal UCR, MCS-150, and Form 2290 — required when operating commercial vehicles on a particular state's highways.
Driver Screening
From $39 (MVR-only); full pre-hire pack from $89
Driver screening combines the Motor Vehicle Record (MVR), CDLIS query, Pre-Employment Screening Program (PSP) report, and FMCSA Clearinghouse query — the four federally-required pre-hire checks for any commercial driver position.
Authority Reinstatement
$275 flat
Authority reinstatement reactivates a previously-revoked or inactive MC operating authority — required when FMCSA has revoked authority due to lapsed insurance, missed MCS-150, unpaid civil penalty, or out-of-service safety violations.

Common questions, plainly answered.
California weigh-station enforcement of UCR begins immediately on January 1. The fee itself doesn't increase, but participating-state inspectors can pull a carrier out of service for any operation past the deadline. File immediately to restore compliance.
