New controversial requirements of the DLA are: (1) provinces and territories in Canada and states in Mexico are allowed to join the DLA and (2) member states, provinces, and territories are subject to reviews by DLA authorities for compliance with the provisions of the DLA. The DLA originated in concept with the 1994 establishment of a North American Driver License Agreement (NADLA) task force, and has created controversy among state representatives opposed to citizen data being shared with other countries. According to a 2005 analysis of the DLA done by the National Conference of State Legislators, the DLA defines "jurisdiction" to allow participation by a territory or province of Canada and by any state of Mexico or the Federal District of Mexico. The DLA can be amended by a vote of at least two-thirds of the member jurisdictions.
