What is an ACD code on a driving record?

An ACD (AAMVA Code Dictionary) code is a standardized three-character code used by U.S. and Canadian motor vehicle agencies to describe convictions, withdrawals, and other events on a motor vehicle record (MVR). ACD codes let jurisdictions exchange driver history in a consistent format.

Who maintains ACD codes?

ACD codes are published and maintained by the American Association of Motor Vehicle Administrators (AAMVA) in the AAMVA Code Dictionary, which is updated periodically as new offenses, withdrawal actions, and license types are added.

Why do MVRs show ACD codes instead of plain English?

MVRs use ACD codes so the same record can be read across state lines. Each state writes its own statute language, but the ACD code maps that statute to a standardized national meaning that screening teams and insurers can interpret.
