Public transport is arguably the safest and most common way for travellers to get around when they're in a foreign country. After all, it almost always ends up where it's supposed to, and in many places, infrastructure and schedules are incredibly high quality.
Having said that, however, like all methods of travel, it does come with its own unique set of risks.
The good news is that there are ways to keep yourself safe while using public transport overseas, and they're quite easy to put in place.
