The International Association of Transportation Regulators (IATR) is a growing peer group of taxi, limousine and for-hire transportation regulators, dedicated to improving the practice of licensing, enforcement and administration of for-hire transportation through the sharing of information and resources. Member jurisdictions are:


Taxi Commissions and Committees, solely responsible for the governance and control of taxi licensing and enforcement;


Police Departments and other law enforcement agencies with responsibility for taxis;


Consumer Protection and Transportation Departments of cities and regions, with responsibility for public safety and service quality;


Airport Authorities; and


State and federal agencies responsible for limousines and other motor carriers, where there are cross-jurisdictional issues

IATR held its first organizational meeting on September 22, 1988 in Tampa, Florida. The organization was incorporated as a not for profit corporation in the District of Columbia on March 8, 1989.
