Imagine you are playing a game where you need to draw a line on the ground with a red crayon. But this is not just any line, it's a very special line called the "red route". To draw this line, you need to follow some rules.
First, you can only draw the red route on certain roads or paths that are marked with special signs. These signs have a red circle with a line through it, like a "no" sign. This means that regular cars and trucks are not allowed on this road or path.
Second, you need to know that the red route is very important. It's meant for buses and other important vehicles to use, so they can get to where they need to go quickly and safely. This means that when you are drawing the red route, you have to make sure that it is clear and not blocked by any other cars or people.
Third, when you see a red route sign, you know that you might see a lot of buses and other important vehicles using this road or path. So you have to be careful and make sure to watch out for them. And if you are ever walking or biking on the red route, you need to make sure to stay on the side of the road so you don't get in their way.
In summary, the red route is a special road or path that is only for important vehicles like buses. When you see a red route sign, you know that you have to be careful and make sure it is clear for these vehicles to use.
