Reduced cash/stored value is for Pico Rivera K-12 students and may only be used on Montebello Bus Lines. You may add cash value on any MBL bus or online to use it on any TAP participating transit agency.
Any MBL Student Monthly pass may only be used on Montebello Bus Lines. If you need to board another TAP participating agency bus, you may purchase an Interagency Transfer or add cash value to your TAP card at the time of boarding to properly board a MBL bus.
MBL does not accept Metro passes or any other agency's passes. Montebello Bus Lines only accepts MBL Day Passes, Student Passes, cash value, and Interagency Transfers (IAT).
This means you do not have a valid MBL pass or any cash loaded onto your TAP card, so your card is not valid to board MBL. You may add cash or purchase a Day Pass or a Student Pass at the time of boarding to properly board a MBL bus.
You may still add cash value, purchase a Day Pass or a Student Monthly pass on board any MBL bus or at the Montebello's Transportation Department, but it will not be subsidized and it will be at full value.
