Imagine you are playing with your toy cars on a big road with two or more lanes. You can drive your cars on any lane you want, but sometimes some lanes are faster than others because there are fewer cars or there are no big trucks or buses. The same thing happens in real life for cars and trucks on highways.
Local-express lanes are special on highways where there are more than two lanes. They have two types of lanes: local lanes and express lanes. The local lanes are like the regular lanes that we use every day. They take us to the nearby exits and entrances of the highway. The express lanes, on the other hand, are like the fast lanes. They take us longer distances without stopping at the nearby exits or entrances.
Think of it like this, you and your family are going to a big park. You can take the regular streets and stop at all the traffic lights and signs, or you can take the highway and drive directly to the park without stopping. The regular streets are like the local lanes of the highway, and the highway is like the express lanes.
Drivers on the highway can choose which lane they want to drive on based on where they want to go and how fast they want to get there. If they want to exit soon, they can drive on the local lanes. If they want to travel fast over a long distance, they can drive on the express lanes.
So, local-express lanes are like having different choices of roads where you can pick the one that fits your need to get where you want to go faster and easier.
