FMCSA Data Dissemination Program

Overview

The Federal Motor Carrier Safety Administration (FMCSA) created the Data Dissemination Program as a mechanism to share the FMCSA regulated entity census and safety performance information at no charge to the public. The goal of the program is to increase citizen participation in government, create opportunities for economic development, and inform decision making in both the private and public sectors.

The datasets for FMCSA regulated entity data as well as other Department of Transportation (DOT) operating administrations are located on the DOT - Public Data Portal (DataHub) website.

The FMCSA datasets are organized into four categories:

Entities with a USDOT Number
Entities with Operating Authority
FMCSA Safety Measurement System (SMS) Data – All active Motor Carriers
FMCSA New Entrant Safety Assurance Program Out of Service (OOS) Orders

The relevant data dictionary containing the data schematics and definitions are also located on the DOT - Public Data Portal with each data file.

Please note that the Data Dissemination Program will undergo changes as the Agency modernizes its architecture and data schema in preparation for the launch of the FMCSA Registration System, Motus, in 2025. DataHub files will continue to be made available in the interim at no cost. For more information about the changes and when they will occur, refer to Registration Modernization Resources Hub | FMCSA.

Entities With a USDOT Number

The “Entities with a USDOT Number” datasets are generated from a 24-hour old database, which are updated daily and usually available on the DOT - Public Data Portal by 12:00 PM EST.

Data for “Entities with a USDOT Number” are broken out into three data groups:

Company Census File, Crash File, and Inspection Files. These data categories exclude inactive, shipper only business types, and entities that have an active Hazardous Material Special Permit (HMSP) on file at FMCSA and USDOT Pipeline and Hazardous Materials Safety Administration (PHMSA).

Company Census File

The Company Census File contains records of active entities registered with FMCSA. Active entities include those entities subject to the FMCSR, Hazardous Material Regulation (HMR), or intrastate non-Hazardous Material (HM) carriers. To identify each entity, FMCSA assigns a unique number to each entity record. This number is referred to as the USDOT Number.

The data within the Company Census File is updated daily from a 24-hour old database. Data within the Company Census File does not reflect real-time data. The Company Census File doesn’t include inactive USDOT Numbers, shipper only business types, and/or entities that have an active HMSP on file at FMCSA and PHMSA. Therefore, the Company Census File data may differ from what is shown in other Agency systems that are refreshed on a different schedule.

Company Census File | DOT - Public Data Portal contains FMCSA registered entity identifying data, business operations, carrier review, equipment, and driver data. The attachment section of the Company Census File | DOT - Public Data Portal also has the relevant Data Dictionary and Schematic.

Crash File

The data within the Crash File is updated daily from a 24-hour old database. Data within the Crash File does not reflect real-time data. The Crash File doesn’t include inactive USDOT Numbers, shipper only business types, and/or entities that have an active HMSP on file at FMCSA and PHMSA. Therefore, the Crash File data may differ from what is shown in other Agency systems that are refreshed on a different schedule.

The FMCSA Crash File contains data from federal, state, and local police crash reports involving drivers and vehicles of commercial motor carriers operating in the United States. Each report contains about 80 data elements pertaining to the motor carrier, driver, vehicles, and circumstances of a crash. Due to sensitive and/or privacy restrictions, driver and hazardous materials data are not included in any crash files released to the public.

Crash File | DOT - Public Data Portal may contain multiple records for a crash. Separate reports are entered for each commercial motor vehicle involved in a crash. These multiple reports can be distinguished by combining the REPORT_STATE, REPORT_NUMBER, REPORT_DATE, REPORT_TIME, and REPORT_SEQ_NO fields. The attachment section of the Crash File | DOT - Public Data Portal also has the relevant Data Dictionary and Schematic.

DISCLAIMER: The information contained in this Crash File represents data that was reported to FMCSA through the requirements of state and federal programs.

NOTICE: This webpage is provided under the sponsorship of DOT in the interest of information exchange. The U.S. Government assumes no liability for its components or use thereof.

QUESTIONS: Crash data in the Crash File are sent to FMCSA by state and federal enforcement agencies. Only those enforcement agencies can resolve concerns about missing or inaccurate crash information. For the name of the proper contact person in each state or to resolve any other questions about the content of this file, please contact FMCSA.CDO@DOT.GOV.

Inspection Files:

The data within the Inspection Files are updated daily from a 24-hour old database. Data within the Inspection Files do not reflect real-time data. The Inspection Files don’t include inactive USDOT Numbers, shipper only business types, and/or entities that have an active HMSP on file at FMCSA and PHMSA. Due to the physical size of the Inspection Files, FMCSA publishes three years of historical inspection data going back from the date the Inspection File was generated on DOT - Public Data Portal. Therefore, the data within the Inspection Files may differ from what is shown in other Agency systems that are refreshed on a different schedule.

FMCSA is the agency within DOT that is responsible for monitoring and developing safety standards for commercial motor vehicles operating in interstate commerce.

The FMCSA Inspection Files contain data from state and federal inspection actions involving Motor Carriers and Transporters of Hazardous Materials operating in the United States. Most of the inspections were conducted at the roadside by State personnel under the Motor Carrier Safety Assistance Program (MCSAP).

Federal and State field enforcement staff perform inspections on Interstate and Intrastate Motor Carriers and Shippers and Transporters of Hazardous Materials. Violations of FMCSR that are severe enough may result in a vehicle and/or driver being placed "out-of-service."

The data from inspection activity is collected and stored in the FMCSA Inspection Data Files.

Inspection data is broken down into the following separate data files: Vehicle Inspection File; Inspections Per Unit; Vehicle Inspections and Violations; Special Studies; Inspections and Citations.

Vehicle Inspection File

The data collected from inspection activity is collected and stored in the FMCSA Inspection Data Files. Due to privacy restrictions, driver information is not included in any inspection files released to the public.

FMCSA Safety Measurement System (SMS) Data – All Active Motor Carriers

FMCSA Safety Measurement System (SMS) data refreshes monthly. It provides measurement results for Commercial Motor Carriers’ public behavior using Behavior Analysis and Safety Improvement Categories (BASICs) method. Data files in Safety Measurement System (SMS) are organized into two (2) categories: SMS Input Data Files and SMS Output Data Files.

SMS Input Data Files

The four input data files are snapshots of datasets taken on the third or last Friday of each month, contain the publicly available census, inspection, violation, and crash data used for the current month’s SMS calculations:

SMS Input - Motor Carrier Census Information | DOT - Public Data Portal This data is from an FMCSA Comprehensive Safety Analysis (CSA) monthly data run, which contains the FMCSA registration data of all active Interstate and Intrastate Hazmat Motor Carriers of property and/or passengers. Contains the USDOT Number, company names, addresses, contacts, telephone and fax numbers, e-mail, HazMat flag, passenger carrier flag, number of power units, number of drivers, mileage, mileage year, operation, and classification registration information. File is comma delimited. One carrier per row.

SMS Input – Inspection | DOT - Public Data Portal This file contains identifying information for the inspection such as the U.S. DOT#, Report Number, Inspection Date, State, and Vehicle Information. It also includes information about the relationship of each inspection to SMS BASIC information, and violation counts by BASIC. File is comma delimited. One inspection per row.

SMS Input – Crash Data | DOT - Public Data Portal This file contains the publicly available crash data used for the current month’s SMS calculations. The file contains a record for each commercial motor vehicle involved in a crash including the U.S. DOT#, Report Number, Crash Date, State, and Vehicle Information.
