Tolong jelaskan mengenai Discounted fares dari Massachusetts Bay Transportation Authority

Discounted fares as well as discounted monthly local bus and subway passes are available to seniors over 65, and passengers who are permanently disabled who utilize a special photo CharlieCard (called "Senior ID" and "Transportation Access Pass", respectively). Holders of these passes are also entitled to 50% off the Commuter Rail fares. Passengers who are legally blind ride for free on all MBTA services (including express buses and the Commuter Rail) with a "Blind Access Card".

Children under 12 ride for free with an adult (up to 2 per adult). Military personnel, state police officers, police officers and firefighters from the MBTA service area, and certain government officials (Commonwealth Department of Public Utilities employees and state elevator inspectors) ride at no charge upon presentation of proper ID, or if dressed in official work uniforms.

Middle school and high school students receive the aforementioned discounts on fares. Student discounts require a "Student CharlieCard" or "S-Card" issued through the holder's school which is valid year-round. College students are not generally eligible for reduced fares, but some colleges offer a "Semester Pass" program. A special "Youth Pass" program was introduced in 2017, allowing young adults less than 25 years old who reside in participating cities or towns and are enrolled in specific low income programs to pay reduced fares.
