Commercial Driver License Information System (CDLIS) Subcommittee

The primary mission of the Federal Motor Carrier Safety Administration (FMCSA) is to reduce crashes, injuries, and fatalities involving large trucks and buses. The Commercial Driver License Information System (CDLIS) contributes to this by ensuring only qualified drivers are driving commercial vehicles on our nation’s roadways. The CDLIS application and procedures are major components to assist in the oversight of the commercial driver licensing program.

CDLIS has been in operation since April 1992. It serves as a clearinghouse that each of the 51 jurisdictions (50 U.S. states and the District of Columbia) can check before issuing a commercial driver's license. CDLIS helps to ensure a commercial driver has only one license nationwide. It also ensures that all convictions are reported to the licensing state and made part of the driver's record.

The CDLIS Subcommittee provides guidance and direction on improvements, enhancements, and changes related to the CDLIS application and processes. The group addresses known limitations and identifies opportunities to support future growth and improvements. 


  • Analyze current CDLIS functionality and provide prioritized recommendations for future improvements to CDLIS functionality
  • Define business requirements (to include assessing any federal rule making to determine its impact on CDLIS)
  • Review and provide recommendations on issue resolution
  • Provide input on the timing of changes for implementation
  • Provide and support ongoing communications between the subcommittee and the broader AAMVA community
  • Endorse and promote subcommittee decisions within the CDLIS community

Change Management

The subcommittee also supports a process for change management to initiate discussion of and request enhancements to the CDLIS system.

Goals of Change Management within CDLIS

  • Provide a consistent and well-defined mechanism for stakeholders to initiate discussion of and request enhancements to the CDLIS system
  • Encourage stakeholders to properly vet enhancement requests prior to formal submission
  • Provide a streamlined process that results in better tracking of and more timely responsiveness to enhancement requests
  • Provide the submitter with the ability to determine the status of his/her enhancement request at any time
  • Provide all stakeholders with transparency to vetted enhancement requests

 If you have identified a need for a change to CDLIS, follow these steps.

  1. Write a brief description of the business need or issue.
  2. Describe your change request and how it addresses the business need or issue.
  3. Vet the business need and your change request (#1 and #2) internally within your organization to ensure that the need for your change request is supported by your organization from both a business and technical perspective.
  4. Contact a subcommittee representative to discuss your request to ensure that:
    • Your change request has not already been submitted by another stakeholder
    • Your change request is needed based on potential insight into how other states might be addressing the business need or issue
  5. Submit your request. You will receive confirmation of receipt, including an identifying change proposal number. You can check the status of any submitted change request by sending a request.  


The CDLIS Subcommittee is comprised of jurisdictional and regional representatives. Regions are divided further into sub-regions so that each sub-region representative is the point of contact for five or fewer jurisdictions. See below for representative designations.
