A commuter pass is a ticket or card that allows individuals to use public transportation, such as buses, trains, or subways, for a specific period. These passes can be purchased for daily, weekly, or monthly use, providing a cost-effective way for regular travelers to save money compared to buying single tickets. Commuter passes are often available for various transportation systems, including local transit authorities and regional rail services. They may also offer additional benefits, such as unlimited rides within a designated area or discounts for students and seniors, making them a popular choice for daily commuters.
