Public transport is like a big bus or train that lots of people can use to go places. It's like a big car that can fit lots of people at the same time, and it runs on a special track or road.
When you want to go somewhere but don't have a car, you can use public transport to get there! This is especially useful if you don't live close to the place you want to go or you don't know how to drive.
To use public transport, you need to buy a ticket or a special card that lets you ride on the bus or train. Sometimes you have to wait a little while for the bus or train to arrive, but once it does, you get on and take a seat.
You can also bring your friends or family with you on public transport, and you can even eat, drink, or play games while you ride.
Public transport helps people save money because it's cheaper than taking a taxi or driving a car. It also helps the environment by reducing the number of cars on the road and the amount of air pollution they create.
So next time you need to go somewhere, consider using public transport!
