How to Pay Your Fare on MAX
Using a ticket
There are no fareboxes onboard MAX. Before boarding, buy your ticket from a ticket machine or validate your previously purchased ticket in the validator located near the ticket machine. A validated ticket is your proof of payment, good for two hours on buses, MAX and Portland Streetcar. Keep your ticket until you have completed your trip.
Using a pass or bus transfer receipt
If you have a TriMet pass or bus transfer receipt, just board MAX and have a seat. (Check the expiration time at the top of your transfer; you may board until that time.)
