Interstate vs. Intrastate: Know Which Path You Need

The requirements depend on whether you will operate across state lines (interstate) or only within Idaho (intrastate).

RequirementInterstateIntrastate
USDOT NumberThrough FMCSAThrough Idaho State Police

IRPYesNo

Step-by-Step: Interstate Authority

Step 1: USDOT Number

Apply through FMCSA at safer.fmcsa.dot.gov. Free. Processing takes 1-2 business days.

Step 2: MC Number

Apply through FMCSA. $300 filing fee. Takes 3-4 weeks for full approval.

Step 3: BOC-3 (Process Agent)

Designate a process agent in each state where you operate. Blanket filings cost $30-50.

Step 4: Insurance Filing (BMC-91/91X)

Your insurance company files form BMC-91 or BMC-91X with FMCSA.

  • Minimum: $750,000 for general freight
  • Recommended: $1,000,000 CSL — most brokers require it
  • Call RMS at (208) 800-0640 for a new authority quote

Step 5: UCR, IFTA, IRP

  • UCR: Annual registration at ucr.gov
  • IFTA: Apply through Idaho State Tax Commission
  • IRP: Apply through Idaho DMV

Step-by-Step: Intrastate Authority

Step 1: USDOT Through Idaho State Police

This is the key difference — intrastate USDOT numbers in Idaho come through Idaho State Police, NOT FMCSA. Contact Motor Carrier Services: 208-334-8611.

Step 2: Form E Insurance Filing

Your insurance company files Form E with Idaho Motor Carrier Services.

  • State minimums: $25,000/$50,000/$15,000
  • Recommended: $1,000,000 CSL — state minimums are a trap. One accident on I-90 in winter will blow through $50,000 in seconds.

Step 3: Vehicle Registration

Register vehicles with ITD. Vehicles over 10,000 lbs in Idaho overnight for business need temporary registration.

Idaho-Specific Tips for New Carriers

  • Idaho is one of the lowest-cost states to base a trucking operation. No toll roads, no weight-mile tax.
  • The color-coded weight system lets you run heavier loads on designated routes.
  • Pacific NW owner-operators often establish business in Idaho for cost advantages while running loads into Oregon and Washington.
  • Shop your insurance at 12 months. First-year premiums are always higher. RMS specializes in finding competitive rates for carriers with clean first-year records.
