The AAMVA Code Dictionary (ACD) is a key component to driving records. The ACD Codes reflect provisions in federal regulations dealing with commercial drivers. The states use the codes to identify the type or reason for a conviction and the reason for a driver withdrawal such as a suspension, revocation or withdrawal when communicating with the Commercial Driver’s License Information System (CDLIS) or with the Problem Driver Pointer Systems (PDPS). Many states have adopted these three-character codes in their own proprietary conviction code tables, especially when indicating out-of-state convictions.
The American Association of Motor Vehicle Administrators (AAMVA) is the copyrighted owner of the ACD. AAMVA recently released a new version – ACD Release 5.0.0 – which is scheduled to take effect on September 1, 2013. There are additions, deletions, and revisions of codes.
