511 Phone Access for the Hearing and Speech-Impaired
To access 511, hearing and speech-impaired callers simply dial 711, the national three-digit number for access to Telecommunication Relay Services (TRS), and ask the operator to connect them to the 511 service by calling 1-888-500-4636. Once connected, the 711 operator will act as a go-between, relaying callers' requests for travel information to the 511 system and then providing system responses back to the callers. All transportation information available in the 511 system can be accessed by hearing and speech-impaired callers.
