Title IV of the ADA amended the landmark Communications Act of 1934 primarily by adding section 47 U.S.C. § 225. This section requires that all telecommunications companies in the U.S. take steps to ensure functionally equivalent services for consumers with disabilities, notably those who are deaf or hard of hearing and those with speech impairments. When Title IV took effect in the early 1990s, it led to the installation of public teletypewriter (TTY) machines and other TDD (telecommunications devices for the deaf). Title IV also led to the creation, in all 50 states and the District of Columbia, of what was then called dual-party relay services and now are known as Telecommunications Relay Services (TRS), such as STS relay. Today, many TRS-mediated calls are made over the Internet by consumers who use broadband connections. Some are Video Relay Service (VRS) calls, while others are text calls. In either variation, communication assistants translate between the signed or typed words of a consumer and the spoken words of others. In 2006, according to the Federal Communications Commission (FCC), VRS calls averaged two million minutes a month.

When it is not obvious what service an animal provides, only limited inquiries are allowed. Staff may ask two questions: (1) is the dog a service animal required because of a disability, and (2) what work or task has the dog been trained to perform. Staff cannot ask about the person’s disability, require medical documentation, require a special identification card or training documentation for the dog, or ask that the dog demonstrate its ability to perform the work or task.

Service animals – For evidence that an animal is a service animal, air carriers may ask to see identification cards, written documentation, presence of harnesses or tags, or ask for verbal assurances from the individual with a disability using the animal. If airline personnel are uncertain that an animal is a service animal, they may ask one of the following:
· Psychiatric Service Dog is a dog that has been trained to perform tasks that assist individuals with disabilities to detect the onset of psychiatric episodes and lessen their effects. Tasks performed by psychiatric service animals may include reminding the handler to take medicine, providing safety checks or room searches, or turning on lights for persons with Post Traumatic Stress Disorder, interrupting self-mutilation by persons with dissociative identity disorders, and keeping disoriented individuals from danger.
WAVE is a suite of evaluation tools that help authors make their web content more accessible to individuals with disabilities. WAVE can identify many accessibility and Web Content Accessibility Guideline (WCAG) errors, but also facilitates human evaluation of web content. Our philosophy is to focus on issues that we know impact end users, facilitate human evaluation, and to educate about web accessibility.
...the full and equal enjoyment of the goods, services, facilities, or accommodations of any place of "public accommodation" by any person who owns, leases, or operates a place of public accommodation. Public accommodations include most places of lodging (such as inns and hotels), recreation, transportation, education, and dining, along with stores, care providers, and places of public displays.

A. The ADA requires that service animals be under the control of the handler at all times. In most instances, the handler will be the individual with a disability or a third party who accompanies the individual with a disability. In the school (K-12) context and in similar settings, the school or similar entity may need to provide some assistance to enable a particular student to handle his or her service animal. The service animal must be harnessed, leashed, or tethered while in public places unless these devices interfere with the service animal's work or the person's disability prevents use of these devices. In that case, the person must use voice, signal, or other effective means to maintain control of the animal. For example, a person who uses a wheelchair may use a long, retractable leash to allow her service animal to pick up or retrieve items. She may not allow the dog to wander away from her and must maintain control of the dog, even if it is retrieving an item at a distance from her. Or, a returning veteran who has PTSD and has great difficulty entering unfamiliar spaces may have a dog that is trained to enter a space, check to see that no threats are there, and come back and signal that it is safe to enter. The dog must be off leash to do its job, but may be leashed at other times. Under control also means that a service animal should not be allowed to bark repeatedly in a lecture hall, theater, library, or other quiet place. However, if a dog barks just once, or barks because someone has provoked it, this would not mean that the dog is out of control.
If you do get sued, if you immediately remediate your website, you may be able to get the lawsuit dismissed on mootness (there’s no longer anything in dispute, i.e. plaintiffs are arguing your website is inaccessible but you’ve already made it accessible). This definitely does not mean you should wait to fix your website but it does mean you may have an out.
As organizations around the world scramble to bring their sites into compliance with the World Wide Web Consortium’s Web Content Accessibility Guidelines (WCAG), focus on other, preexisting accessibility regulations has also intensified. The United States’ Americans with Disabilities Act (ADA) is one of the most visible and one of the most complicated pieces of legislation in the sphere of accessibility. Let’s look at some of the ins and outs of what an ADA compliant website means today.
A person traveling with a service animal cannot be denied access to transportation, even if there is a “no pets” policy. In addition, the person with a service animal cannot be forced to sit in a particular spot; no additional fees can be charged because the person uses a service animal; and the customer does not have to provide advance notice that s/he will be traveling with a service animal.
Federal law isn't the only consideration for businesses. Additionally, each state interprets the law differently. Consider the case against Netflix in 2012. Lawsuits were brought in federal court in Massachusetts and California. Netflix was accused of violating the ADA by not offering "closed captioning" options for its Internet streamed movies. Illustrating the complexity of this issue, the courts reached completely opposite decisions. Massachusetts held that Netflix must comply with the ADA, while the California court found that Netflix did not fall under the ADA's definition of "public accommodation."
