Okay, kiddo! Imagine that there is a person whose job is to help cars and people move safely and avoid accidents on the roads. This person is called a traffic warden.
Their job is to wear a special uniform and stand at a specific location, like a crossing, a junction, or even a car park, where there is a lot of traffic coming and going.
They hold a baton, which is like a stick, and they use it to signal to cars, bikes, and pedestrians whether they should stop, go, or wait. They might blow a whistle to get everyone's attention and to warn them of danger.
Traffic wardens also watch out for cars that are parked illegally or in places where they shouldn't be, like in front of a fire hydrant or on a footpath. If they see this happening, they can fine or ticket the driver so they will hopefully learn not to do it again.
Overall, the traffic warden's job is to keep everyone safe and make sure that traffic flows smoothly without there being any accidents.
