The Americans with Disabilities Act (ADA) of 1990 is a law in the United States that prohibits discrimination against individuals with disabilities in public areas. The ADA sets accessibility standards and requires reasonable accommodation to allow people with disabilities to fully enjoy the same rights and opportunities as others. The law covers a wide range of areas, such as employment, access to public buildings and services, transportation, and communications. The main objective of the ADA is to promote equal opportunities and the full participation of people with disabilities in society.
