## Abstract

FMCSA codifies the statutory requirement that State driver licensing agencies (SDLAs) implement a system and practices for the exclusively electronic exchange of driver history record (DHR) information through the Commercial Driver's License Information System (CDLIS), including the posting of convictions, withdrawals, and disqualifications. The rule aligns FMCSA's regulations with existing statutory requirements set forth in the Moving Ahead for Progress in the 21st Century Act (MAP-21). The rule also establishes a date by which States must be in substantial compliance with this final rule.
