You can of course use cash. The fare box will accept bills up to $20 for multiple riders. Pennies and $1 coins are not accepted. All other coins are accepted. The driver does not carry change. If you pay with three $1 bills, you will not get your 25ยข refunded or credited. You will also have to pay for every trip even if you have to take 3 trips to get where you are going. The only exception will be the free routes which will be noted in another page.
