Belgium has buses as their public transportation. Normally, you can check the information of the buses online on the Internet. Just check De Lijn website to get some information about route and time of buses in Belgium. You can find information about what bus that you need to take to go to your destination place and when the bus will leave from the nearest station or bus stopping place.
If you are a tourist, you can just pay one time trip to the bus driver inside the bus. You need to mentioned the place where you want to go then the bus driver will tell you how much you need to pay. He will give you the ticket after you pay. Small money or coins would be better so the bus driver does not have to take his time to give you the chance, since he need to continue driving.
You can only stop the bus in the bus stopping place or the station. And when you arrive in your destination, simply press the bell so the driver can stop the bus for you to go out of the bus. But when you are waiting for your bus and you see the sign "GEEN DIENST" on the bus, it means that the bus is out of service. They will not stop to bring you to your destination place.
