A public light bus is like a tiny bus that carries people around cities. It looks like a big van with windows and seats inside.
Lots of people in some countries like Hong Kong and Philippines use these small buses to travel around town because they are easy to get on and off and can go to many places.
The driver usually gets paid by how many people he takes on the ride, so it is important for him to drive around the city and pick up as many people as possible.
Even though public light buses are smaller than regular buses, they still follow the same traffic rules and have to stop at red lights and stop signs.
So, if you want to get around a crowded city quickly and easily, you can try riding on a public light bus!
