ADA

The ADA or Americans with Disabilities Act of 1990 is a law that prohibits discrimination against people with disabilities, and also ensures them equal opportunity for employment. Not only does this law include employment opportunities, but it also ensures that public accommodations, commercial facilities, and transportation are equally accessible to those with disabilities. 

For the full version and all of the amendments to this law over the last almost two decades you can visit the official website at www.ada.gov. There is so much information here it was hard to process, they have publications for misinterpreted info. and also to help businesses comply with the Law as well.
