Every organization that employs drivers must ensure that they are hiring qualified and safe motor vehicle operators. Fortunately, there are several methods to obtain this information, one of which is the Commercial Driver’s License Information System (CDLIS). A CDLIS report assists in confirming that your drivers possess the appropriate licenses and are safe operators, thereby helping you maintain compliance with both state and federal regulations.

What is a CDLIS?

The Commercial Driver's License Information System (CDLIS) is a comprehensive national database that allows state driver licensing agencies (SDLAs) to verify that each commercial driver possesses a single driver license and maintains a complete driver record.

  • The CDLIS is a database comprising state DMV records, which include the current and up to three prior commercial motor vehicle licenses.
  • As a best practice, employers seeking to hire CDL drivers should obtain CDLIS reports, utilize the FMCSA’s Pre-Employment Screening Program, review state motor vehicle records, and examine previous employment records.
  • CDLIS reports serve as a crucial tool for transportation companies to identify a driver’s license number, enabling them to verify the qualifications, endorsements, driving history, and compliance of truck driver candidates through a motor vehicle record (MVR).

Through our US Drug Test Centers software, you can run a CDLIS for all new drivers, to ensure that they possess only a single driver’s license and comprehensive driving record, and that they do not maintain any active commercial driver’s licenses or permits in other states.
