Look for a METRO bus stop signs (located throughout Portland and Westbrook, along Route 1 in Falmouth, at/near Maine Mall, and along Route 1 and downtowns in Yarmouth, Freeport, and Brunswick). The routes served are listed on the sign.
Signal the Bus Driver
Use a hand motion to signal the bus driver at the bus stop.
It is a good idea to arrive at your bus stop five minutes before the bus is due to arrive. The route you want to take will displayed on the top of the bus (this is called a Destination Sign).
