Mission and History

The DUI Defense Lawyers Association (known as "DUIDLA") was incorporated in June of 2014. The organization became a 501c(6) non-profit organization in order to promotes excellence in aggressively defending those charged with DUI or DWI related crimes across the United States.

DUIDLA provides training and education to its members who include many of the top DUI attorneys across the United States. At last count, the organization had approximately 800 members. The stated purpose of DUIDLA is:

"To protect and ensure by rule of law those individual rights guaranteed by the state and Federal Constitutions in DUI-related cases; to resist the constant efforts which are being made to curtail these rights; to encourage cooperation between lawyers engaged in the furtherance of these objectives through educational programs and other assistance; to serve as the first and last line of defense of the Constitution; to assist attorneys and public defenders in obtaining advanced training in DUI related areas through our education scholarship grants."

Members are encouraged to take on leadership positions within the organization. DUIDLA prides itself on transparency and intends to:

  • publish all financial aspects of the organization on the members-only section of its website;
  • hold meetings that are open to all members when important decisions are made impacting the organization; and
  • elect its leaders through a democratic vote.

DUIDLA serves attorneys, both private attorneys, and public defenders, in obtaining knowledge and advanced training in DUI-related areas. The organization is a network of women and men across the country committed to DUI education and outreach.
