Yes, you can! Remember to touch your card to the yellow card reader but DO NOT touch out again when you alight or you’ll be charged a penalty fare.
FYI: In 2016, a ‘Hopper Fare’ was brought in, which allows you UNLIMITED travel on TfL buses and trams within 60 minutes from the time you first touch your Oyster card to the card reader on a bus or tram. This means that, whether you use one or 10 buses within that hour, you only pay for one.
