What is TTY often used for in emergency situations?

TTY, or Text Telephone, is specifically designed to enable individuals who are deaf, hard of hearing, or have speech impairments to communicate over phone lines. In emergency situations, TTY is crucial as it provides a reliable means for these individuals to access emergency services and convey essential information without the need for spoken dialogue.

This technology allows a user to type messages that are then transmitted over the phone lines and displayed as text on the receiving device, enabling clear, effective communication. This capability is essential in emergencies where voice communication may not be possible.
