QCMobile App User Guide

The Federal Motor Carrier Safety Administration (FMCSA) QCMobile app allows convenient access to FMCSA’s motor carrier data for interstate truck and bus companies. QCMobile provides access to the same information that is available on FMCSA’s website. 
Public access via QCMobile serves to make our roadways safer by providing easier access to carrier operating authority, registration and safety performance information, and safety ratings. QCMobile does not make any new information available to the general public. Users with FMCSA Portal access can view additional carrier safety performance details.
The convenience of QCMobile will prove to be a valuable law enforcement tool by immediately revealing if a carrier is under a Federal out-of-service order (OOSO) and retrieving registration information. Motor carriers that operate in violation of a Federal OOSO order are ignoring regulations and consciously disregarding the law. FMCSA considers the continued operation of a carrier despite an OOSO to be a serious threat to public safety. Checking the carrier’s USDOT number to ensure the carrier is not out-of-service is a critical component of all roadside enforcement activities.
QCMobile is free and available for both Android and iOS devices and can be downloaded through the Apple App Store or Google Play.  
Following is a Quick Start guide on how to use QCMobile for iOS devices. QCMobile will operate the same through an Android device. Please note -- the trucking company depicted here does not exist and was created for demonstration purposes only.

Getting Started

  1. Download the QCMobile app through the Apple App Store on your iPhone/iPad.
  2. In the App Store, search for “QCMobile”.
  3. Touch the “GET” button to download the app. You might be prompted to enter your Apple ID and password.
  4. You can verify that the QCMobile app is being installed by going to your home screen.
  5. Once the QCMobile app is installed, touch it to launch it.

Searching for a Carrier

  1. On the home screen you can search a carrier by their name, DOT number, or MC number.
    • Name
    • DOT Number
    • MC Number
  2. Click anywhere on the carrier name to see a detailed view.
  3. Click on the carrier name again to see details on the carriers “Carrier MC Number(s)”, “Power Unites and Drivers”, “Carrier Operation”, “Operation Classification”, and “Cargo Carried”. The “i” will provide a description of what each tab means.
  4. The first view will provide information on “Operating Status”, “Licensing and Insurance”, “BASICs Overview”, “Roadside Out-of-Service Rates”, “Crashes”, and “Safety Rating”. The “i” will provide a description of what each tab means.
    • Operating Status
    • Licensing and Insurance: Active for-hire authority, authority status, and insurance type
    • BASICs Overview: From the detailed screen, users can also access the carrier’s Safety Measurement System (SMS) Behavior Analysis and Safety Improvement Categories (BASICs): Unsafe Driving, Hours-of-Service Compliance, Driver Fitness, Controlled Substances/Alcohol, and Vehicle Maintenance. The data in the SMS is performance data used by the Agency and enforcement community to prioritize motor carriers for further monitoring. The SMS is not a federal safety rating. For more information on the SMS, please visit the “Use of SMS DATA/Information” tab in the settings wheel in the top left hand corner of the app, as well as the SMS website at
      • An example screenshot of one of the BASICs, “Hours of Service”. A carrier’s on-road performance in each BASIC is based on 24 months of inspection and crash data. Performance percentiles are calculated on a 0-100 scale, with 100 indicating worst performance and 0 indicating best performance. For example, a percentile of 98 means that 98% of motor carriers in the same safety event group have better on-road performance in this BASIC than this carrier. Intervention thresholds are organized by BASIC and are set based on a given BASIC’s relationship to crash risk.
    • Roadside Out-of-Service Rates
    • Crashes
    • Safety Rating
  5. If users have an FMCSA Portal account, they can use the “Log In” feature and their FMCSA Portal username and password to access additional information. The login screen can be accessed by clicking on “Log In” on the top right corner. FMCSA Portal users have access to the Crash Indicator and the Hazardous Materials Compliance Behavior Analysis and Safety Improvement Categories (BASICs) as well as the Inspection Selection System (ISS) score. The general public does not need to login to see the majority of the information displayed in the QCMobile app. For information on obtaining an FMCSA Portal account, visit
