What Is the UCR Program?
The Unified Carrier Registration (UCR) program replaced the former Single State Registration System (SSRS). It requires certain transportation companies to register annually and pay a fee based on the size of their fleet.
UCR is administered by a multi-state agreement, and Idaho participates fully in the program.
Who Must Register for UCR in Idaho?
You must register for UCR if your business:
-
Operates in interstate commerce
-
Has a USDOT number
-
Transports property or passengers across state lines
-
Is a:
-
Motor carrier
-
Owner-operator
-
Freight broker
-
Freight forwarder
-
Leasing company
-
Important: Even one truck crossing state lines triggers the UCR requirement.
Does UCR Apply to Idaho-Based Trucking Companies?
Yes. Idaho-based trucking companies must register for UCR if they operate interstate, even if:
-
You only cross state lines occasionally
-
You are leased to another carrier
-
You are a single-truck owner-operator
-
Your truck is registered in Idaho
UCR applies regardless of whether you haul freight for hire or operate under your own authority.
Intrastate vs Interstate Operations in Idaho
| Operation Type | UCR Required? |
|---|---|
| Intrastate only (within Idaho) | No |
| Interstate (crossing state lines) | Yes |
If your trucking business never leaves Idaho, UCR is generally not required. However, once you cross state lines—even once per year—UCR registration becomes mandatory.
How UCR Fees Work
UCR fees are based on the number of commercial motor vehicles in your fleet:
-
Owner-operators with 1 truck pay the lowest fee tier
-
Larger fleets pay higher fees based on fleet size
-
Brokers and freight forwarders pay a flat fee (no trucks required)
Fees are paid annually and must be renewed every year.
When Is UCR Due?
-
UCR registration is due every year
-
Typically opens in October
-
Enforcement usually begins January 1
Late registration can result in fines, citations, and roadside enforcement issues.
How Is UCR Enforced in Idaho?
UCR enforcement in Idaho may occur through:
-
Roadside inspections
-
Weigh stations
-
Compliance audits
-
FMCSA and state enforcement agencies
Failure to register can result in:
-
Fines
-
Out-of-service orders
-
Delays at weigh stations
UCR vs USDOT Number
Many carriers confuse these two:
-
USDOT Number: Identifies your company for safety tracking
-
UCR: Annual registration and fee requirement for interstate operations
Having a USDOT number often means you also need UCR, but they are not the same.
Why UCR Compliance Matters for Idaho Truckers
Staying UCR-compliant helps you:
Avoid fines and penalties
Pass inspections smoothly
Maintain good standing with FMCSA
Operate legally across state lines
Final Thoughts
If your trucking company in Idaho operates interstate, UCR registration is not optional—it’s a required annual compliance step. Even small fleets and single-truck owner-operators must register if they cross state lines.
