# How to get a DOT number

A USDOT number is free and you apply with FMCSA online. The harder part is what comes after: operating authority if you haul for hire, insurance filings, a BOC-3, UCR, and a new entrant safety audit in your first year.

## Do you need a USDOT number?

-   You operate in interstate commerce with a vehicle over 10,001 lbs gross weight or combination weight
-   You transport 9+ passengers for compensation or 16+ passengers not for compensation
-   You haul hazardous materials in quantities that require placards
-   Many states also require a USDOT number for intrastate commercial vehicles

## Steps to get your DOT number and authority

-   Apply through FMCSA's registration system. The USDOT number itself is free. FMCSA is moving registration to its new Motus system, so check fmcsa.dot.gov for the current portal.
-   If you haul regulated freight for hire across state lines, apply for MC operating authority (FMCSA charges a fee per authority type).
-   Have your insurer file proof of liability insurance with FMCSA.
-   File a BOC-3 through a process agent.
-   Register for UCR, and set up IRP plates and IFTA if you run interstate.
-   Set up drug and alcohol testing, driver qualification files and a maintenance program before your first load.

## The new entrant safety audit

New carriers enter an 18-month monitoring period and get a safety audit, usually within the first 12 months. Auditors check driver files, hours of service, drug and alcohol testing, vehicle maintenance and insurance. Some violations are an automatic fail, such as using a driver without a valid CDL or medical certificate, or having no drug and alcohol testing program.

## Get a DOT number questions

### How long does it take to get a DOT number?

The USDOT number is usually issued right after the online application. MC authority takes longer because of a protest period and the insurance and BOC-3 filings.

### How much does a DOT number cost?

The USDOT number is free from FMCSA. Operating authority has a federal fee per authority type.
