Starting a trucking company, filing by filing

What you have to file, what it costs, and when it's due, checked against FMCSA, IRS, and state sources. No quote forms, no filing service to sell you.

14,367 new USDOT numbers were added in September 2026, according to FMCSA's Company Census File. See the trend and your state.

Which rules apply to your truck?

Cargo van, box truck, hot shot, or semi: the federal rules turn on weight. Find the lines your truck crosses.

  1. Under 10,001 lbs
    Not a commercial motor vehicle by weight under the federal safety rules. A for-hire carrier whose whole fleet is under 10,001 lbs GVWR (non-hazardous freight) files at least $300,000 in liability coverage.
  2. 10,001 lbs and up
    Rating or actual weight, truck alone or with its trailer. In interstate commerce it's a commercial motor vehicle:
    • USDOT number
    • Medical certificate (DOT physical) for the driver
    • ELD for hours of service, unless an exception applies
    • $750,000 liability for for-hire general freight in vehicles rated 10,001 lbs or more
  3. 26,001 lbs and up
    • CDL: Class B for a single truck; Class A for a combination when the trailer is rated over 10,000 lbs (rating or actual weight, whichever is greater)
    • IFTA fuel-tax license if you run in two or more IFTA jurisdictions: two axles and over 26,000 lbs, or any vehicle with three or more axles
  4. 55,000 lbs and up
    Form 2290 heavy vehicle use tax, based on taxable gross weight

Simplified. Each rule measures weight its own way, and hazardous materials or passengers change the rules.
