Traffic lights use different colors around the world so people can understand what to do easily, just like how you know red means stop when you play with your toy car.
Why Different Colors?
Imagine you're playing a game with friends. If everyone uses the same rules, it's easier for all of you to know what to do next. That’s why traffic lights use red, yellow, and green, they’re like signals in a big game where cars are the players.
But sometimes, people in different countries choose slightly different colors or even shapes for their traffic lights. It's just like how some kids draw houses with square windows and others use circles, both are correct, but they look a little different.
How We Know What to Do
When you see red, it’s like your teacher saying “time to stop and think.” When you see green, it’s like getting a green light to run and play. Yellow is like a friend shouting, “get ready!”
Even though the colors might look different in some places, they all help people know when to go or stop, just like your favorite toy helps you learn new things every day!
